5DIV can only do 3 sec. continous shooting ?!

Quite surprised at the shallow RAW shooting ability of the 5DIV. Its single processor + CF slot can only push 21 full raw frames in one burst limiting continuous shooting time to 3 sec. Almost half of the 5DIII(!!).

Canon could have used a processorset-up like the 5DS/R or CFast to change this - even if I'd prefer not to deal with yet a third card format myself.

Now, I very seldom shoot long bursts, but if I where to get a 5DIV to supplement my 5DS/R that actually makes its far less of an obvious upgrade for action shots to me.

Even the 5DS/R will shoot for ~3.7 sec @ 5fps (18-19 shots) before slowing down. 5DIV has 40% more fps, but the 5DS has >20% longer time to follow the action when that's important. For me its mostly short bursts 3-4 pictures and once in a while (very seldom) long bursts - but these few times I really want the burst to be as long as possible. YMMV.

5DIII could keep shooting much longer reaching ~5.2 sec @6fps with a fully charged battery - or for even longer as fps drops as the 5DIII battery level drops (I know it can only do 6fps as long as you do not use both card slots and forgo the added safety...).

It is a surprising limitation, it's a shame Canon didn't offer a CFAST version(a la Nikon D5), I guess it's still possible that the 1DX2 and 5D4 could be offered a CFAST upgrade via a service visit later on, I mean if Nikon can do it......

Also worth noting that the 5D4 does have 2 processors, 1 Digic6 and a Digic6+

3 seconds at 7fps is a lot of photographs. Some CF cards will improve on that figure. The 5DIII has a subtle issue where the buffer drops dramatically if the SD card is in use or engaged in the menu system. Many photographers don't realise this and use put raws on the Cf card and jpeg on the SD card and then find that their buffer only lasts a second. The 5D4 doesn't suffer with this due to the faster SD card slot. But if it's such a problem, the 5D4 might not be the right camera for you...go get a 1DxII, that's got an unlimited buffer.

Agree DxII is the camera to get for action shots. 5-6-7 fps is not "fast". 14 fps makes a real difference.

Just seems Canon got the balance wrong here with a little more fps but only almost half the shooting time compared to the 5DIII.

Accroding to the Digital Picture review of the 5DIII and specs of the 5D4...the 5DIII was good for 18 raw files or 13 if dual card writing is enabled. That's 3 seconds or just over 2 seconds. Which is the same as the 5D4...so where did this "5D4 has lost half of it's raw burst speed" come from? It hasn't, it's still the same as a 5D3.

From my experience FPS has to be taken in conjunction with burst capability as well... if a subject takes say 3-6 seconds to move across the FOV and you fill the buffer after 2-3 seconds at 7fps then wait another 5 seconds for the buffer to clear than that's not very good....would prefer a lower fps and higher burst rate. Still with the iV you can lower the FPS to cover the FOV.

What is the fps when using silent mode?
On 70D you have 3 speeds: silent, normal and high. Different fps for each mode. Does the 5D4 not have the same?

5DIII could do up to 33 RAW shots in a single burst using the right card and full battery power. 18 in a burst probably was an early measurement and faster CF cards got available(??).

21 frames @7 fps @ 30mpix doesn't seem bad for an 'all rounder camera'. Still, I am kind of surprised the buffer isn't a little larger.

What are you shooting that absolutely needs 3+ sec continuous with out modulating the shutter to extend buffer depth?

Would you say that 8 fps is fast enough for action shots or do you need 14?
Every fps helps (even if there's a very practical limit to fps usability). My point is that diminishing returns set in much faster than people consider. The difference between 5-6-7 fps is almost irrelevant for your keeper rate.

For some of course that small difference may still matter.

There are three different ways of stating the buffer capacity, and Canon is conservative in its specs.

The most conservative method is to use the physical buffer size and presume that all pictures are taken simultaneously. 21 photos will fill it. But that isn't physically possible.

The second figure you'll see is the number of shots that can be taken before the buffer actually is full, taking into account the seconds that occur during the filling up. For instance, the 7D2's buffer is a 25-shot buffer, but you get 31 shots before it fills up with a not particularly fast card.

The third - and, for me, the most accurate - is how many pictures I can get with a 1066x card. With the 7D2 that's 41-44 pictures, or about 4 seconds of shooting.

We won't know the latter figure for the 5D4 until it gets into the hands of people who are willing to share this information. I suspect it'll be in the 30s and roughly the same period of time that the 7D2 can shoot before filling, which would translate to about 30 pictures and about 4 seconds.

One of the most intriguing questions I have about the 5D4 is whether or not it'll supplant my 7D2 for wildlife. Between the all-over F/8 autofocusing, improved resolution that makes it on par with the crop cameras for pixels/duck, and the quieter shutter, it'll be an interesting competition. The big disadvantage will be the missing 3 fps, but I'm not anticipating buffer will appear very different.

Pixels/duck must be the most practical unit I found regarding resolution. Kudos to you. :D

However, the calculation is not exactly right, made the same mistake myself previously. To get the same 1.6 magnification from cropping out the the 5D4 you'll end up with roughly 12MP (30.4MP/1.6/1.6, or use the fact that an APS-C sensor is roughly 40% the size of an FF sensor, so 30.4MP x 0.4 = 12MP).

Nothing to sneeze at, but far from the 20MP of the 7D2, so less pixels/duck. :)

Have to go up to 5DS/R sensor to change the pixel/duck balance.

I love pixels/duck term. Of course its inventor was wrong about pixel density but this term more than makes up for the mistake. And 5D4 makes a nice compromise if light becomes less than optimal.

EDIT: Can you imagine future super resolution cameras advertisements: More pixels/duck ;D

Ok, now back to my question.

Would you say that the DIGISUPER 75 is a camera? Please answer with either "Yes" or "No."

If you're not going to answer others' questions, why should you expect they'll answer yours? ::)

Ack, yes, I forgot about the "square" nature of the crop factor. Good point. It'll still be an interesting competition between image quality, especially at the higher ISOs I am forced to use to get the shutter speed up.

If I were to guess right now, I would predict the 5D4 will win in most circumstances, excepting really fast action and super long distances (both of which I shoot frequently).

As for the pixels/duck, I'm merely using the term of art I've seen here on the forum. Can't claim authorship.

Pixels/duck - I love it, no matter who thought of it. :)

As far as fps, how satisfied you are with a certain speed depends on what you're shooting. If it's sports, and you're shooting a single action, like a ball flying into a net, which happens only a few times in 90 minutes, you definitely want as many fps as you can get during its flight.

I shoot birds, and if I'm shooting a small falcon with fast wingbeats, I may not need high fps because during one second there are several complete wingbeats and a higher chance of getting good wing position on any single frame. But an eagle may have only 1-1/2 wingbeats in a second, so the camera is going to have to make up that chance for the perfect wing position by firing more times. If I've got a 5D4 and a 7D2, I'm more likely to try for the perfect shot with the 10 fps camera. The extra 3fps increases my odds of getting that perfect position by a considerable amount on a slow-flapping bird. I've had many 3-second bursts in which I never got that really good position on the bird, or I got a good position but the nictitating membrane was covering the eye (and how fast does THAT happen?).

So for my purposes, having great DR (for underwing shadowing) and 14fps (100% better chance of a great shot) will be worth an extra 1.3 pounds. (I'm not convinced that the 5D4 will have outstanding DR.)

Do you realize all of the recent xD models from Canon have menu options for the user to set the frame rate for high speed continuous and low speed continuous shooting? The 7D Mark II, for example, allows anywhere from 2 to 10 fps for HSC and anywhere from 1 to 8 fps for LSC. It won't let the two overlap, so if you set HSC at 6 fps the fastest you can set LSC would be 5 fps. If LSC is set to 7 fps the slowest you can set HSC is 8fps.

If you want to stretch 20 or so frames to 5 seconds total time, reduce the HSC rate to 5fps.
