a6700 vs a7cr ...

The A6700 is the better buy because it’s lighter, smaller, and much cheaper.

If money is no issue but capped at the price of A7CR, I'm taking the A6700 for sure. I shoot some sports with it and the rolling shutter is well controlled with the A6700 so it will be my pick. Now of course if my budget is more than the A7CR then I will take the A9MKIII.

If price is not an issue, the A7CR is an easy choice. For me, the MP difference makes the decision very easy to make.
I initially passed on the 6700 hoping for a A7CR model to be released... and that actually materialized. Then I looked at the video capabilities and the 6700 is better overall in that department - sort of annoying as it is half the price. If I did not care about video, I may have gone the other way. The latest APS-C lens releases though give the crop format a big boost I think. Two of the later examples are the Sony 15mm1.4 and the remarkable Viltrox 27mm 1.2. If one is after the megapixels in FF though, 7CR is the way to go.

If the question is which camera, not considering price, the A6700 has a mechanical shutter, the A7CR has 61mp, there are some low light/noise differences, perhaps not significant, there isn't a one for one lens congruence, there's an 18-135 and 28-200 but no aps-c "20-70," etc. "Fast" primes for light gathering or shallow depth of field. Ignoring prices, the aps-c lense could be lighter and smaller.
A7CR has the same sensor as A7RV, doesn't It?
And photonstophotos.net basically says A7RV in APS-C is just A6700. Therefore, I expect, (disclaimer: I can't be sure), A7CR to behave exactly as A6700 when in APS-C mode. More over when in this article (https://www.sony.com/electronics/support/articles/00229990 ) they say both cameras drop to 12 bit when in ES + Continuous Drive + Lossy RAWs.
So yes if money is not an issue go for A7CR... But only if you ever intend to use FF lenses on it. It would be quite stupid using only APS-C lenses...
(And I don't know about video. I'm not a videographer myself. I don't know how they compare there)

A6400 smaller than A7c R ... A6700 is bigger than A6400 (similar to A7c R)...
A6400 is the last one in the serie with a good size for an APS-C
Yeah, I kind of wonder if this makes sense if you use, say, the 70-350G, where the crop-factor will help give you more reach, but for shorter focal lengths, you use FF lenses.

I wonder how the EVFs compare? That might help me decide.
The pixel density of both cameras is very close. The A7CR is 266 pixels per mm and the 6700 is 264. So their resolution with APS-C lenses is about the same.
I have lenses that I enjoy on both my A7R4 and my A6400, such as the 28-60mm. But that lens affords a wider field of view on the FF body. But don't think the 6700 has greater reach. It has narrower field of view for a given lens, but that is not greater reach. See:
petapixel.com
The wider field of view of FF (for a given lens) could be sometimes advantageous. Suppose you seek 1000 pixel wide images to share online (a typical size) and you shoot a scene at a basketball game. You have about twice as many 1000 pixel images to choose in any FF frame than in the APS-C frame. But this is an unusual situation and I would probably never encounter it.

Probably. I haven't seen it confirmed butmaybe someone has compared them internally. I don't think sony has said.

The 70-350 is kind of a special case. There aren't a lot of longer aps-c lenses. You get the 105mm-525mm angle of view at the aps-c /A6700 26mp resolution at size, weight, and price savings compared to lenses like the Sony 70-300 or the Sigma and Sony 100-400s, etc., so it's a worthy choice on the smaller A7CR. Mid-range and wider lenses may have some size and weight advantages, maybe price, but they advantages aren't as clear as with the 70-350.

If money is no issue, the A7Cr is the easy choice. You get essentially two cameras in one. If you're a video shooter first, the A6700 is the better choice. Both are great on their own, I think the A6700 is the better value if money comes into play, which I would think is the case for most of us.
Yeah, I think money is going to be the main obstacle for me. It's just hard to justify the extra cost. Maybe it'd be different if I were getting poor results, but I get good results out of APS-C -- heck, even 1" sensors are starting to look good, at least with a bit of AI help.
But yeah, if money were no object, I think I'd have a hard look at A7Cr. If the price drops down near the A6700 price level, it will be as I've said for many years -- why bother with APS-C, when you can get FF for almost the same price? But it's still not there yet. And the size is still significant. But it's getting closer...............

The CR has a mechanical shutter too - it`s just that its only second curtain - the only detrimental affect this has, is that it can mess up bokeh when using very fast lenses wideopen at high shutter speeds .

If money is really not a concern, the a7cr it’s almost identical in size (a bit taller but less depth, only 20grams heavier) but has better features, more controls and you can take advantage of both aps-c lenses and full frame.
A7cr in crop mode has 26mpx so same as a6700. Pixel size is similar as well for noise concerns.
all said it is still double the price.
i have not tried the a6700, but I did use the a7cr a bit and it is a beast. Both suited for regular/small hands; handling with big hands won’t be great on either

The A7CR pixel size is same as A6700, so don't expect you will get better dynamic range and ISO performance which is the advantage of FF usually, it will be on-par only. Go for A7CR if you mostly shoot landscape and need a larger print, otherwise can't see the reason for that. But again buy an A7CR for use in crop-mode, can't really think the logic behind.
This is true in APS-C mode. But in FF mode, you get more pixels and more surface area, so overall noise level and DR will be improved.
Seems like overkill for most of us. But there are those who want more! Always, more....
If you ONLY used it APS-C mode, it doesn't make sense. But considering you might use it in FF mode most of the time, and only APS-C for special situations where you swap to an APS-C lens, you're at least no worse off than having the APS-C camera in the first place. As long as people understand the tradeoffs, it should make sense.
