I do think that Canon have been too conservative with the memory card slots (the jibe of "welcome to 2012" is not unwarranted). Sure, as long as it'll use the fastest UHS-I speeds (of around 100MB/s, which is 800Mb/s) then either/both cards will be fine for even 30fps 4k MJPEG (60fps would be a stretch on the SD card, but the 5D4 doesn't support it anyway).

However, it is an issue for stills. The sub-$2000 Nikon D500 claims up to 200 raw images, and has a UHS-II SD slot (as well as XQD), so the 5D4 looks pretty poor in comparison.

The 7D got a firmware update that increased the buffer size, and the cynic in me suspects it was less about better optmised memory handling, and more about increasing a constant in the code that would allow it to use a bit more of the internal memory. Memory's dirt cheap these days, and even with 40MB raws, a paltry 1GB of RAM is enough for 25 shots (before you even touch the card). The fact that a number of Canon's bodies now have apparent buffer sizes that are good for exactly 3 seconds of shooting makes me suspect there's probably more RAM available - it's just limited by a constant in the firmware. I mean - it's not like we're griping about 5 vs 6 shots; it's 21 vs 200 (even allowing for the 50% greater resolution of the 5D4, the D500 buffer is way higher, and would be able to empty that buffer to the cards way faster).

I am actually surprised that more company's don't use the XQD cards. With more file size and video all the time it makes sense.

Just out of interest, does anyone know if it's possible to change the video codec by way of a firmware update ?
Maybe Canon could change it in a future update or Magic Lantern could come up with something..

i suspect you are right about ML and the fact that a firmware update could change compression algorithms for the the 5DIV video. I'm not much of a video guy but struggling to match up different types of video (codec/resolution/FR etc) between my two bodies is ridiculous. It should not be difficult at all to get the same video out of every Canon DSLR.

can't disagree. Up until maybe 8-10 years ago, Apple always had a "Detect Displays" button in the Displays control panel. Then after one update it just disappeared. Drove me nuts for a few weeks until I googled it and found that if you press the Option key, the button magically appears. There is ZERO reason to make that kind of change other than trying to control the user experience to such a degree it becomes a PITA.

I don't know how common my style of shooting is, but I have never hit my 6D buffer limit in real world shooting, and have never really given the reasons for limiting it much thought. But you're right, throwing 1 GB of RAM in there should easily change that.

With a fast action sequences and a naturally faster camera, you will hit buffer limits more often. Faster cameras change your behavior a bit.

btw, raw analysis of the 5DIV: http://www.fredmiranda​.com/forum/topic/14479​74 (external link)

About 13.3 - 13.4 EV at ISO 100 (noise level about 3 DN)

That was true when I posted that link earlier, but supposedly now a file was found that had about 13.6 on it. More info will come out once this camera hits the mainstream testers. Lots of folks were hoping to get closer than 1 stop away from Sony DR.

That is why I buy aftermarket grips for less than $100. The price canon wants to charge is outrageous for what you are getting.

And probably very close in quality to the 100.00 aftermarket units as well..total Rip off on canons part. But they kept the body intro prices the same so I guess they are trying to make it back someplace

No SD needs to go away. I bought a card reader for my newest PC. I still haven't used it three years later. I just plug in the camera and download. From now on, wifi needs to be fast enough to download with no physical connection.

That won't work for people who have numerous cards and/or cameras to unload.

All these mirrorless fan-boys are saying DSLRs are going out, but I don't see that happening at all. The smaller package seems nice, but when I went from a T3i to a 7D, I couldn't believe how uncomfortable it was to hold such a small camera. To be fair, my hands are fairly large so that definitely plays into it. But looking at photos of cameras like the a6300 or some of the m43 cameras, all I can think about is how awkward it would be to hold them. The lighter weight would be nice, but I'd take good ergonomics over a lighter weight any day. And don't even get me started on battery life :lol:

For me, there is one draw for mirrorless, and that's the ability to shoot handheld video using the viewfinder instead of the rear screen.

Not enough to make me switch--too many other reasons to stick with Canon until Canon figures mirrorless out.

The Meike one I picked up had the same feel as the Canon grips, really grippy rubber, it had the vertical controls, including the joystick, etc. I never had any issues. Others had some issues with Meike grips, supposedly, but not sure if it was the same generation as the one I had. They are more plastic, and the battery door could be a bit finicky from time to time, but I took that savings and put it toward the purchase of the 70-200 II.

Exactly

I am all Godox for flash and OCF set ups

Godox V860's do the same thing as the 600's from canon

189.00 v/s $550.00

No Brainer

Godox flash is perfect. TTL is better than Canons TTL plus I can put it on the X system and use it with my strobes or on a 5 light set up.

Canon is screwing people with their flash units. Godox changed the game for sure

It is interesting that after 5 years and multiple camera cycles, Canon has yet to reach the capabilities of the EXMOR, but 1 stop is pretty trivial.


Not sure why, but call me JJ.

Well hopefully they are enhancing the new sensor design for the next gen bodies, like the 6D2, etc. It would be interesting if the 6D2 has even more DR, but less features. I could see Canon continuing this leapfrog feature approach to cause folks to either pick up 2nd or 3rd bodies or constantly change out of the old.

A shame they did not use this sensor on the 5ds..

That wouldn't make any sense, IMO; the 5Ds gives Canon the highest pixel count of any DSLR. It gives all of the FOV benefits and shallower potential DOF of FF, with pixel density like a 7D2 or 70D. I'd buy a 120MP FF with Canon's old base-ISO DR, if it had good noise character, even if it only did burst at 2fps.

Did you mean that the 5Ds should have had the same type of ADC as the 5D4? With that I could agree, but unfortunately, Canon was not ready for that when they felt it was time to release the 5Ds(r).

Why did they not hold off releasing mk4 untill this new design was ready for use?

Still think Canon will do a 120mp camera despite all the engineering difficulties of doing so. It may be a ISO 50-800 only type camera or some kind of limitation but they already showed it off and I think they will release it when it's time.
