How does Sony FS5 compare with Canon C100mkii?

Sony FS5: Best documentary camera ever?

Is the Sony FS5 the best documentary camera ever?

Over the past couple of years, I’ve migrated away from DSLR shooting to pretty much using the EOS c-series cameras, in particular the C100mkii, for most of the documentary-style shooting I specialize in. But a few weeks ago when the Sony FS5 began shipping, I opted to become an early adopter. The specs were just too tempting.

Last week I wrapped production on my first commercial project with the FS5. And while I have a long way to go in exploring this camera fully, I’d like to share some of what I have – and haven’t – observed so far.


First up: I haven’t seen anything nasty in the footage, as others have reported. The only unacceptable quality I’ve seen so far is when shooting in center crop mode in low light, with the gain jacked up to 3200 ISO or higher. That produces nasty pebble-sized grain. But as long as I hang at 0db (ISO 1000 in hypergammas or ISO 3200 in slog) I find the results are spectacular. Razor sharp, crisp detail, plenty of color information to play with in 10-bit HD.

The FS5 gets noisy when pushed past 3200. In fact, I would say it’s best not to push it past 1600 ISO. And in SLOG, don’t pus it at all. It really wants a lot of light. Like one to two stops more than base ISO. So to my way of thinking, this is an ISO 1000 camera, whether you’re shooting SLOG or standard gammas. Set it in your head and forget it. And ISO 1000 is a pretty decent base ISO, isn’t it? The C100mkii’s base is 850. So we’re in the same ballpark with both cameras here. But the C100mkii can be pushed well over 3200 with great results. So Canon retains the edge for low-light shooting.

Canon color science is also more cinematic with less effort. All you have to do to get great looking footage when shooting C-log is drop on a LUT in post. The FS5, in SLOG, also requires dropping on a LUT (more about which ones in a moment). But then you have to do more work. Sometimes much more.

The good news is that the 10-bit HD footage loves to be graded! And it’s actually a lot of fun to push it around and you can do that to quite an extreme without the image falling apart. It’s definitely a different look, the Sony. I read somewhere that because Sony has a long tradition of news cameras, their look is more video than cinema. Canon, with it’s EOS C-series, is gunning squarely for cinematic results. And I have to say I prefer the Canon look. Skin tones look more alive. But it’s a subtle thing. I like the image coming out of the FS5 a lot, it’s just different from the C100mkii.

The first project I shot with the camera didn’t lend itself to shooting SLOG (as Allister Chapman has eloquently argued, SLOG isn’t good in low light) so I shot in PP6, which is Hypergamma 3/cine. No LUT required, off we go. Here’s how a few of the interview frames looked without too much grading – I just added a little Film Convert using FS7 settings:

1 2 3

You can see that the last guy’s skin tones are unfortunately rather lifeless, but that’s not the camera’s fault:  I didn’t do a good enough job flagging him off from ghastly artificial light in the warehouse location where the interviews were shot, so you get a lot of that light showing up under the key.

Regarding 4K, I haven’t shot with it enough to comment. And I don’t plan to use much 4K anyway. That’s not why I bought this camera. It’s a pain in the ass to edit 4k (at least on my circa 2011 iMac) and none of my clients are asking for it. The only reason I can imagine using it regularly would be for getting two shots out of an interview, but in most cases I’d rather have the 10-bit than the 4K. Still, it’s very nice to have the option, something the C100mkii doesn’t.

In my SLOG shooting tests, I definitely find that this camera needs to be overexposed by at least one stop to keep noise down in the shadows. This makes monitoring a challenge. With the FS5, you’re stuck with just a single LCD mode that boosts the contrast to help with focus – but does nothing to reduce the overexposure. Not good enough! You really do need to shoot with a LUT when shooting SLOG.

LUTs are not supported by the FS5, however, so to use them you need a third-party monitor that supports them. I rented the SmallHD 502 on the advice of Seattle DP Gabriel Miller, and liked it so much that I bought one after using it for a single day. I wouldn’t dream of shooting without it now. It’s screen is almost as big as my DP6, but it’s tiny. A photographer friend asked me if it was my iPhone when he first saw it! And ultra lightweight. It lives on the top handle of my FS5, without compromising the compact form factor of the camera. Unlike the Atomos Ninja, which I also rented. Way too big and makes the whole thing top-heavy. No good.

So, which LUTs to use for monitoring (and post)? I’ve found two very good LUTs for this purpose. The first is the Sony Alexa emulation LUT. It comes in two flavors, one- and two-stop pushes. The second is a higher contrast version of the same LUT, with a one-stop push, called AA709A, that was developed by Art Adams. I’ve packed up all three and tweaked them so they’ll work with the SmallHD 502. You can download the FS5 LUTs here.

Next up, I’d like to talk about my favorite thing about the FS5: it’s body.

The ergonomics of the FS5 are SUPERB. It’s the first camera I’ve used in years that makes me want to shoot handheld. And I’m doing it all the time now. I’d basically forgotten that shooting handheld was even an option for me, ever since trading in my JVC HM100 for a 5dmkii. Even with the C100mkii, I find it wants to live on a monopod. But not this camera. It begs to be held in your hand, and it’s so easy to get great results with it, because it’s so light and so easy to MOVE with it. It’s changing how I think about shooting b-roll.

With both the FS5 and the C100mkii, the beauty is you can arrive on location and pull your camera out of the bag and begin shooting without building anything. But I give the FS5 the edge here, because even with my SmallHD 502 monitor attached and rotated horizontal, it measures just 10” high. That’s enabled me to turn my unused Steadicam Merlin travel bag into the perfect grag-and-go camera case for the FS5. It’s the perfect size bag to fit camera with my Canon EFS 17-55mm f/2.8 zoom lens, with Metabones IV adapter, a shotgun mic, and 502 monitor attached. The only thing I have to do to begin shooting is rotate the monitor to the right shooting angle, and press record.

I find myself picking up the FS5 with my right hand, by reaching into the grip, squeezing it, and lifting it, one-handed. It’s so light you can do that. It just balances in your right hand like an extension of your body, freeing your left hand to focus, operate the menus, and to cradle the camera for stability. That right handle is perfectly balanced. Really, the design team at Sony deserves an award for the FS5.


I haven’t used the FS5 with any Sony lenses. I am using it with my Canon EF glass, using the Metabones adapter and speed booster. Unfortunately my Contax Zeiss set won’t work with speed booster, because there are elements on the lenses that protrude too far.  I haven’t been able to try out the autofocus features of the camera with Sony glass.

The nice thing about the Metabones adapters, at least the version IV one that I have, is that the firmware issues others have reported seem to be resolved. Changing the iris behaves as expected, with the aperture dial on the camera. Also, image stabilization works perfectly on Canon glass with the adapter. My go-to lens on the C100mkii has been the the Canon EFS 17-55mm f/2.8, and it works flawlessly on the FS5 with the Metabones adapter.

It’s also very nice to be able to punch in to center crop mode and get even more reach from the lens.  But I do find that center crop works best in plenty of light. The Clear Image Zoom feature is also handy, but in the situations I’ve tried it, I definitely noticed a drop in image quality. Not as bad as most digital zooms, but enough that I won’t plan on using it regularly. Apparently the feature works better in some situations than others, because it uses a database of images to determine what image processing to apply. This will require more testing before I determine its strengths and weaknesses.

To compare with the C100, the Sony FS5 is definitely a manual focus camera. I LOVE the autofocus on the C100mkii, and I will continue to rent the C100mkii when I have projects that need snappy autofocus such as sports shooting or other situations where I don’t have time or mental bandwidth to chase focus. However, paired with the 502, manual focusing with the FS5 is a joy.

Using the 502, I’m able to gauge focus on the FS5 very precisely. A quick flick of the joystick zooms me into the image to check focus while rolling, and the way SmallHD has implemented peaking on the monitor is superb. So I really don’t find I miss the C100 autofocus so far.


I have rigged up my FS5 with a Manfrotto quick release plate, which allows me to go instantly from rails and follow focus on a tripod, to handheld configuration. The camera is so lightweight that I have to rig it up and raise the center of gravity in order for it to balance on my Vinten AS5 fluid head. But the quick release gives me the best of both worlds: super stable, controlled tripod shooting one minute, and nimble handheld the next.


With a C100mkii, I use an external monitor mounted to an arm coming off a rail block. But with the FS5, I’m finding it most convenient to put the lightweight, compact 502 monitor right on top of the handle using a Manfrotto LCD ball head. This is a heavy ball head! It weighs as much as the monitor itself. But it’s buttery smooth in its operation, almost effortless to adjust, unlike the cheaper, lightweight ball heads. These have to be cranked down so hard it hurts your thumb, and they work loose and sometimes fall off. So it’s worth every penny and every ounce to get the Manfrotto. It’s the right tool for the job.


I find myself shooting with both the LCD and the 502, keeping the menu display active on the LCD, and the 502 clear of menus so I can focus and frame without any distraction. With the latest firmware, you now have the option to send the menu display to the external monitor, should you wish, as you can on the C100mkii. But the C100mkii’s monitor is in a much more awkward place than the FS5, which is completely configurable however you like it, and depending on your shooting situation. But the EVF on the C100mkii is superior to the FS5s, which feels just adequate.


It makes sense to have everything as light as possible with this camera, and to that end, I purchased a very thin, very flexible thin gauge 24” SDI cable that SmallHD makes. It works amazing. This little guy is what you want for monitoring. HDMI cables don’t cut it! I’m SO very glad that FS5 includes an SDI out, something the Canon C100mkii does not. I can’t tell you how many times I’ve cursed the C100mkii when the signal drops out momentarily to my external monitor because I simply touched the HDMI cable. So yay for no more HDMI cables. And with the SmallHD SDI cable, you get the same thin flexibility as a thin HDMI cable. Yay!



Another neat trick with the FS5 is to get Swit S-8U63 batteries that include a d-tap. I picked up 3 of these, which aren’t cheap at $180 apiece. But three batteries is enough for me to shoot all day. I get about 2.5 hours shooting time per battery while also powering the SmallHD 502. Also great news is that with the Sony FS5 charger, these batteries go from empty to fully charged in less than an hour. *UPDATE:  A reader commented that these batteries occasionally reset the camera clock on the FS5. This is something I’ve observed, but didn’t know it was the fault of the battery. So if you rely on accurate timecode for your projects, you should avoid Swit batteries for now, and choose Sony’s OEM batteries instead.


The ND wheel that allows you to smoothly and steplessly adjust the ND to control exposure is the killer feature of this camera. I can’t overstate how epic this is. Finally, a tool to control exposure without stepping the iris and changing depth of field! It’s the best thing ever for documentary style shooters. Goodbye, matte box. I don’t know if I can shoot anything else again after using this. And apparently Sony is going to release a firmware update that allows this to be set to an auto mode, which will automatically set the correct exposure using only this ND. How cool is that?

The slow motion features are fantastic, but I haven’t had a chance to use them much yet, so I won’t comment on that other than to say it gives me great pleasure to know that 240fps in full 10-bit HD is  just a button push away when I want it.

To sum up, I love this camera for it’s body. Does that make me shallow? I don’t think so. This camera has taught me that form IS function.  I’ll continue to admire the C100mkii for its look, for its autofocus and low light capabilities.  But for now I’m going steady with the FS5.

    Thanks so much for this Dan! I’m currently on the brink of upgrading from a 5dmkiii and i’ve been doing so much research. In particular, I’ve been looking at the FS5 and the c100mkii. Your review has helped me tremendously! Quick question…for your interviews, did you shoot with just the FS5 or did you also have a B cam? If so, what did you use as your B cam? Jus wondering. Thanks! Love your work!

    1. Dan McComb Post author

      Thanks JC, glad you found it helpful. Having shot with a 5dmkiii for years myself, I think you’d be thrilled with either camera.

      Regarding the interviews, they were all one camera. For this project I will be using the interviews with extensive b-roll and timelapse footage, and only very briefly cut to them to establish the speaker. In fact I often don’t even shoot interviews – just record them, audio only. It’s a trick that forces me to shoot better b-roll and often results in better performances by non-professional talent. For those times when two angles are necessary, I’m looking forward to shooting 4K and just cropping in for the close frame. But I haven’t tried that yet.

    Hi Dan,

    First of all, thanks for your comparison-really great article and I enjoyed reading. I have fully equipped GH4 and I’m more than happy but I need someting for “pure” run’n’gun shooting, so I’m on the fence here – C100 mk2 or FS5?! Would you be so kind to tell me image wise and/or IQ/resolution of the picture in HD – who is really better ?
    Thanks in advance.
    Cheers, Sven

    1. Dan McComb Post author

      Hi Sven, most def, any DSLR is going to be a pain for running and gunning compared with C100mkii or FS5. Both cameras have a superb image, resolution wise. But the edge goes to Sony here, because you can choose 4K if you really want the resolution. The C100 has a 4K sensor but only gives you the option of HD. Image wise, if you compare graded SLOG footage next to graded C-log footage from these cameras, there is more dynamic range from the FS5, by about two stops. That’s VERY nice to have.

      Apart from that, I prefer the Canon look. It’s slightly more cinematic, warmer, with better skin tones. The FS5 can look a little clinical. But if you have the luxury of spending time with the footage in post, you can really push the 10-bit SLOG footage around, and get the look you want. With the C100mkii, you’re stuck with 8-bits, so the image won’t hold up as well with extreme grading. But Canon is correct when they say they have “the right 8-bits,” so as long as you’ve exposed correctly, your image probably won’t need much grading anyway.

    Nice review, but don’t you have any problems with the SWIT batteries? I had them initially but sometimes they would reset the internal clock & timecode when inserting a fully charged battery.

    1. Dan McComb Post author

      Ah, so THAT’s why the clock is sometimes reset! I wondered what was causing that. Thank you for sharing that info, very helpful. In my case, I’m prepared to put up with the hassle of an occasional clock reset to gain the convenience of the d-tap, but then, I rarely rely on timecode. For projects that require timecode, I’ll be sure to stick with OEM batteries.

  4. Christopher Rompre

    Hi there,
    That’s a fantastic idea to power the SmallHD with the D-tap. I didn’t see how you connected the D-tap cable to the 502 monitor. Is there a DC in, or did you need an battery adapter?

  5. Tim Kang

    Solid review!
    I’ve been looking for a solid comparison article for these two cameras for awhile now and man.. you definitely went beyond my expectations! I recently just ordered the c100ii and reading this article gave me more confidence that I chose the right camera! Especially with the price drop.
    But maybe one day I’ll get my hands on an fs5 and possibly convert over haha!

    Thank you!

    Hey Dan, I’m loving this camera as well.

    I’m a canon color guy as well and had my eye set on the c300Mkii but then the price scared the crap out of me. Then I thought, well I love the C100mkii but this camera (other then the colour) is killing it for function. That variable ND really is a game changer and isnt even on the FS7.
    502 is a perfect match. I’m thinking of the 702 bright.
    SLOG 3 is nice and easier then SLOG2. I didnt really like preset feature for white balance. I couldnt really find where to manually set Kelvin on the fly other then the Indoor/Outdoor presets. Did you find this?
    Shame the 4k isnt full 4k but hey cant complain.

    I shot a little test with it the other morning at sunrise which you can see here:

    Even with camera totally stripped down I could assemble it with lens, top handle, side grip, monitor timed in 57seconds!

    I cant wait to purchase this soon and just dont want to pickup my A7S anymore lol. Or unless Canon come out with an updated C100 or a C200 this is the way Im going.

    1. Dan McComb Post author

      Hi Shaun,
      I rented the 702 for a project recently and liked it so much I ended up buying one. It’s a fantastic monitor! Too big for running and gunning, but great for interviews and scenarios where you’re on sticks. Outdoors in sunlight I find it still needs a lens hood, but for overcast and other outdoor scenarios, the 1000 nits is plenty bright enough.

      If you want to manually set white balance while shooting SLOG, you just need to select the Pro color mode. Good to go.

      I would sure love it if the 4K were 10-bit, but hey, this camera gives you so many other things and I don’t shoot 4K often anyway. Too much overhead in the edit that I don’t want to incur the workflow hit from pushing all those pixels around.

      It will be interesting to see what Canon announces at NAB, hey? Rumor is they have something aimed at the same specs as FS5, but I’ll believe that when I see it!

      Happy shooting.

      1. Shaun

        “Too much overhead in the edit that I don’t want to incur the workflow hit from pushing all those pixels around.”
        Yeah definitely a laptop cafe edit killer amoung others such as size etc.

        “It will be interesting to see what Canon announces at NAB, hey? Rumor is they have something aimed at the same specs as FS5, but I’ll believe that when I see it!”

        Same! And of course even if it is killer there is lead time and all that jazz which they need to get better at so I think FS5 will do me and I’m sure its a unit I could move very easily if I wanted to switch.

        Thanks for the white balance tip. I didnt shoot SLOG this time. Cine3 only.

  7. Case

    Thanks for the review. It definitely has me thinking more about the Sony. I working with the Sony F3 and I currently work with several C100’s. The C100 would be a very hard camera to part ways with, however, I like the Sony (brand) and the ergonomics of their cameras. Do you happen to have any side by sides or even video footage available somewhere that was shot with the Sony FS5? I am looking for video clips from someone who actually knows what they are talking about. Not some YouTube videos from inexperienced users who are still unsure of their settings. lol
    Thanks again for the review!

    Great Article! I am buying cameras for a Ministry I work for 2 FS7 and 1 FS5 for mobile handheld use, I am having a hard time picking a lens that I could use on a slider and that would have IS. You still recommend that 17-55 or if you could pick any lens what would you get? I have read so much and I am buying so much stuff my head is spinning… this article was very helpful!

    1. Dan McComb Post author

      If I were buying today I’d get Canon 24-70mm f/4 IS zoom, and use it on the Sonys with a Speedbooster. That will give you the equivalent of the 17-55 only with much better IS, due to the hybrid IS that lens has.

    Awesome article! This is an article I’ve been looking for. I’m new with external monitors and SDI, but what is the main difference between the SmallHD 501 and 502. What is the added benefits of the SDI + HDMI connections? Have you tried the less expensive SmallHD 501 for LUT support?

    1. Dan McComb Post author

      Hi Andy,
      The only difference between the 501 and 502 is that the 501 lacks an SDI connector. They both support LUTs equally well from what I understand, although I haven’t used the 501, as I can’t abide the terribly flimsy hdmi connectors. Once you go SDI, you never go back!

  10. Alexandru Pop

    Hello Dan,
    I have a question for you. I want to buy Canon EOS C100 Mark II body, (price $ 3,499.0) or Sony FS5 body (price $ 4,748.00) I have Canon lenses, 70-200 f2.8 and 24-70 f4. Canon. What do you advise me to buy. I in 80% use the wedding room and events. The second question, what lens do you recommend the good kit to shoot for C100 or FS5. thank you.

    1. Dan McComb Post author

      Hi Alex,
      If I were shooting weddings and events most of the time, I’d go with a Canon EOS C100 Mark II over the Sony. One word: Autofocus. It works really well, and with events where you’re running and gunning, it benefits you. Also, the look coming out of Canon Cine EOS is superior, in my view, especially for event shooting, in which you often have to turn your footage around quickly without time to apply LUTs and fuss with the color the way you have to do with Sony cameras when you’re shooting Slog.

      As far as kit lenses, you already have a very good set up. With those two lenses, you should be able to cover pretty much anything that events will throw at you. My kit lens of choice is the Canon EFS 17-55mm f/2.8. It’s a little faster than your 24-70, but covers essentially the same range. I definitely recommend that lens if you’re looking for an extra stop of speed out of your lens.

      1. Alexandru

        Ok, I understand, but c100 is not 4k, what do I do in the future? But how about GH5, do you think it would be better for events?
        Thank you, Dan! 🙂

        1. Dan McComb Post author

          It’s nice to have the option of 4K, for sure. But you have to ask yourself – how are you going to be using this camera most of the time? If you only get occasional 4K projects, then just rent a 4K camera for them. That’s what I do. I don’t use my FS5 for 4K projects anyway, because I want 10-bit when I’m shooting 4K. And I rarely have clients requesting 4K in the space I’m working in. Your mileage may vary.

          I would definitely avoid the GH5 for event coverage, because a DSLR is much more difficult to use ergonomically than a proper video camera. If you don’t believe me, rent both cameras, shoot an event with both, and make your own decision. DSLRs are nice for specific situations (ie, gimbal use, small slider use, and some situations where you want to work discreetly). But for your bread and butter stuff, there’s no substitute for having all the video-specific controls that you need, where you need them.

          1. Alexandru

            Yes it is, I have two variants, I buy FS5 and use canon lenses that they own or Panasonic GH5 and a Panasonic HC X1 camcorder, and then both. What do you get from this offer? I remain grateful for the conversation, and give a beer! 🙂
