What do you need the most in the 5D Mark IV ?

^^^ Agreed.

Looking at the voting stats for this thread got me thinking - what of the above are we actually likely to see?

Based on evidence from Canon's recent releases, it would make sense for a new 5D to have the same basic AF system as the 1Dx II (just as the 5D3 shared most of the 1Dx's). I can't see a new 5D having more AF points than the 1Dx II, and anything lower might be seen as a regression vs the 5D3.

So:

• Bigger AF point coverage across the frame: The 1Dx II has a small increase, so this looks likely (assuming they'll use the same basic AF system)
  
  
• Faster/better low light AF: It would make sense to keep at least some of the f/8 AF capability from the 1Dx II (even the 80D has multiple AF points at f/8, and AF at -3 EV), and reviews of the 1Dx II indicate it's much faster than it's predecessor. Whilst not low light specific, the 7DII and 5DS also have iTR (present on the 1Dx but not on the 5D3), so it would seem odd to leave that off a new 5D
  
  
• More MP: That seems to be the trend, so even if it's a minor increase I suspect we'll see more. Personally I'd like something in the 28-30MP region
  
  
• Better DR: The 80D and 1Dx II certainly point to that happening, and arguably you need low ISO DR in a 5D more than a 1Dx (because the latter is more high ISO oriented)
  
  
• Better ISO performance: Maybe, maybe not. Quantitive testing of the 1Dx II doesn't seem to show much improvement vs the 1Dx, but since the 7D II Canon seem to have made qualititave improvements (that is, the noise that's present has a more pleasing character). Perhaps that partly explains the perception from users that the 1Dx II is visually better at high ISO than its predecesor. Having testing an 80D against the 5D3 I think there are improvements in that area, so a new 5D may well look better vs the 5D3
  
  
• More FPS: Anyone's guess, though again even the 80D has 7fps (nearly matching the old 7D). With the 7DII and 1Dx II there's certainly plenty of headroom for Canon to give us more in a new 5D (without stepping on the toes of the sports focussed bodies)
  
  
• Spot metering for every AF point: No idea (would be nice though)
  
  
• 4K video: Given the 5D's reputation for video, it would seem a little odd for no 4K support to be available. How well implemented it might be is questionable though
  
  
• Lighter weight: Can't really see that happening
  
  
• Better weather sealing: No idea

The above wouldn't be a bad result though surely.

I'd also add a desire for a much bigger buffer depth; on the few occasions I do bursts with the 5D3 I do find it quite restrictive. Something like 24 RAW+JPEG shots at 8 fps (i.e. 3 seconds of burst) would be a good start.

Of course, Canon may throw us a complete curve ball and release something totally different, but hey, this is the rumors forum so I'm allowed to speculate wildly

Your remarks about the 1Dx2 iso performance is just flat out WRONG.......At least a full stop ISO improvement over the 1Dx1, you can pull 5 stops on a DR test, improvements in darks and shadow retention and a much more pleasing noise appearance............​.25000 ISO is usable with the 1Dx2 when properly exposed.....I have used both cameras

Additionally improvements in AF system, particularly Servo, really sets this camera apart from the pack. SERVO does not miss. Best camera I have ever used

You're conflating high ISO performance with low ISO DR. There's definitely significant forward steps regarding low ISO DR (more than 1 stop in fact). Heck - the crop 80D smokes my 5D3 in this area (http://www.photonstoph​otos.net …k%20III,Canon%2​0EOS%2080D).

Looking at quantitative tests of high ISO noise on the 1Dx2 vs 1Dx (e.g. http://www.photonstoph​otos.net …0EOS%201DX%20Ma​rk%20II_14) doesn't hint at much improvement (and numerous reviews I've seen have indicated the same).

However (as I noted in my previous post), Canon have recently been making progress with the noise character (the 7DII apparently being one of the first). The noise I see on the 80D is also less visually objectionable than the 5D3. So (as I noted in my previous post) that may partly help to explain the perception that the high ISO output from the 1Dx2 is better than the 1Dx. That's not sarcastic praise - it's what actually matters. In theory you could have a sensor with slightly lower quantitative noise, but with such worse noise character that images from a slightly higher (quantitative) noise sensor were preferable.

I'm pretty happy with my 5dIII, but I think this is what I'd want the most. I don't use video, so I don't care about that, but for the sake of what year it is, we need 4k video.

Anyway, my list:

1. Better Dynamic Range
2. More AF points towards the corners, if they can fill the frame out more, its almost worth it for that alone.
3. Better low light
4. HDR bracketing with RAW files
5. Higher Resolution

When you shoot RAW the 5DIII already produces the three RAW files which it combines into a HDR-JPG . I use the facility occasionally and never look ath the JPG but put the three RAW files through Photoshop. or other HDR software to produce the end result.

I would love some recoil to accompany that shutter sound. Always disappointed at the store when I mess with the 5D3 and hear the sound without feeling the recoil.

So... you're saying you want your photos blurry?

(I'm not trolling - recoil you could feel would surely have an affect on the stability of the camera, and compromise image quality when shutter speeds drop)

I think they may have been sarcastic implying that the sound of the mirror and shutter was as loud as a gunshot

I just need it to come out soon so the 5DIII drops into my price range.

lol same ... but so many people are also doing this idk if it will drop that much GFX cards don't drop that much with newer models but they push out a lot more.

My 3 things would be a jump in MP (28-30), better HIGH ISO sorry but Low iso DR wont make me money (I don't sell Landscapes and if I screw up a photo that bad I'd generally delete it), and a jump in FPS, I would like 9 as previously rumoured then again every number between 5 and 9 has been rumoured!!
As mentioned in previous posts a wider AF spread would be great as would a better metering system than the 5D3 BUT if I had the first 3 they wouldn't be my biggest concern.

I just need some on-sensor PDAF goodness.

I always joke about how the 5D3 sounds like it has a mini artillery piece inside compared to the other Canon (and Nikon) bodies I've used/tested. Can't speak for the 1D series though. And honestly, the shutter sound is probably my favorite thing about the camera .

I tend to use it on silent shutter mode a lot as that suits my subjects, so generally I think it's really quiet

It did recently do some high speed burst shots using the 5D3 and 7D (mark 1) and must admit the 5D3 felt/sounded sluggish and clunky by comparison (in terms of fps; obviously the AF is better).

A 5D4 with ~9fps and a deeper buffer would tick a huge box for me. I don't need the fps often enough to justify adding a high fps body, but a new 5D4 that was capable in that area would make it an even more ideal all-rounder for my needs.
