Canon announces the 5D Mark IV (and two lenses)

[peety3]

1Dx has 1-2 stops better ISO ability than a 5D3. I'd be surprised if a 5D4 can improve by >2 stops, enough to put it ahead of a 1Dx. On par, maybe.

My wife and I "share a pool of cameras": two 1Dx, a 5D3, a 5DsR. Her technical habits are too sloppy for her to use the 5DsR in most cases, so she usually gets a 5D3 and 1Dx, and I get 5DsR and 1Dx, though on rare occasions I'll take both 1Dx. Overall, it's been a great setup for us (with a trusty 1D3 as spare, serving time at my folks for an occasional bird photo), though I've wished I had another 5DsR as backup (but couldn't justify it in front of other lighting and lens wishes). 1Dx2 does nothing for me; maybe a 1Dx3 with dual CFast, but the incremental fps bump is of no use _to me_. Bring in the 5D4, and now I start looking at it as the potential double-duty camera: upgrade my wife's 5D3 to 5D4, and becomes a much better spare for a 5DsR than anything else we had. Oops, but wait, the 5D4 price is awful close to a 5DsR, AND I can't reuse my grip...now I'm back to a 5DsR (and steal the grip from my 5D3) unless/until the 5D4 price drops.

Based on DPR, I thought I was seeing ~1/3-2/3 improvement of the 5DIV over the 5DIII at ISO 6400. Using DXO data, I see the 1Dx/1DxII at about a 1 stop improvement, the 5DIV likely is closing the gap at higher ISO, but still just a bit off in terms of DR. In terms of other parameters (tone/color/etc), they all seem very close.

EDIT- If I were to guess, I suspect the 5DIV will slip right between the 5DIII and 1Dx I/II above ISO 1600, but exceed the 1Dx and be just below the 1DxII for ISO 100-1600.

Of course, this is just DR.

In terms of other parameters (tone/color/etc), they all seem very close.

I just think it will make the best back up camera for me along with the 1DX not as a replacement or upgrade except for the fact all the focus points are available at f/8. For birders that is huge I can also see perhaps using it at family functions or outings where I would rather not take the bigger/heavier 1DX.

Also with the sale of my 7DII I can easily swing the price right now

Ha...Don't have to convince me. My favorite article I've read on the 5DIV was taking the position that Canon made it too good. That it will be cannibalizing sales from C100/C300/5DsR/etc, maybe even 1DxII.

If real world tests come back as I expect, I honestly think it may be a near perfect "all around" dSLR (8 fps, few other very minor spec things). Which is what I suspect is Canon's intent. The "niche/markets": 1DxII--aimed at high frame rate and those that want the best; 5DsR--high MP crowd that want the ultimate resolution; 5DIV---Event/do everything very well camera. 6D(II)....FF entry level "do everything but not as well" camera at lower price point. That really covers the market really well. Sure people will find nits to pick, but those that own those cameras seem to love them.

As for those going with 2 body kits, I can see offsetting the 1Dx series with the 5DsR (like Rick) if you want the resolution, the 5DIV if you if you want more general purpose FF, or 7DII/80D if you want crop factor/smaller/lighter.
