The A7RII isn't perfect, neither is the 5DSR.

I’d note that perfection is an inappropriate yardstick.

I still largely use my 5Diii for long lenses 200+, though have started shooting 70-200 adapted on my A7Rii (such as below). A lot of what I struggled with using A7Rii has been addressed with the new model. I have yet to see whether with sync port will indeed allow me to drive HSS from my elinchrome monolights. If it does not I may send it back as that was my top priority for an update. I *wish* they would consider making the body 1/2” taller. That would substantially improve handling, IMO.

For those in this thread that do have both the a7r3 and a7r2, I'd love to see a comparison at ISO 100 between the two. Curious to see the DR improvement in real world images.

Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, DR, MP's or AF, it is about the light.

I asked for people with both cameras and real world images. I find these jumbled setups distracting to look at.
But last time I checked these studio scenes the new Sony looked comparable to the new Nikon. I'd say that's pretty good then but I'd like to see something like a slightly underexposed quarter tone.

Comparing dynamic range is challenging to do visually since on all recent cameras it exceeds virtually all displays, meaning you must tone map to see it. If we had 15-stops of capability in the display you might see the differences.

The lower noise of the Riii relative to Rii *should* be advantageous if you desire to push shadows up. That’s rarely my cup of tea, though, and I therefore expect no practical differences with my displays.

I pointed you to controlled comparisons from somebody with both cameras. No 'real world' images can compare to studio setups when looking for tiny differences in small tonal ranges, that is just a fact, so these kinds of results are the very best (most accurate/illustrative) you are going to get. 'Real world' comparisons invariably include a lot of variables and the results are normally subjective rather than measurable and objective.

Download the samples as RAW files and present them any way you find easiest to digest. The bottles give nice and comparable tonality.

I agree the output looks very good, I also believe anybody that thinks there are useful differences in output now is barking up the wrong tree. An appropriate specialist lens is going to make more impact on final output IQ than a virtually unmeasurable difference in sensor output across brands.

In practical terms, as an example, if you own an A7R MkII and shoot architecture (I know you do) I'd expect using one of the new TS-E's is going to make a larger IQ difference in your deliverables than moving to an A7R MkIII. However if you own a 5D MkII/III are looking to up your game and shoot the same, I'd think an A7R MkIII would be a better investment than a lens. However, when all is said and done now output IQ differences are so small between the D850, 5D MkIV and A7R MkIII, other factors really should be bigger deciding factors.

In general I agree with your assessment. In the particular case one could argue the pixel shift brings value to architectural photography. TS-E would *probably* sway me, but it’s a trade between optical distortion and detail/DR/moire-avoidance.

Some bad news, I can’t feel any difference between the grips of the a7r II and A7r III.

And the good news:

It’s more customizable than I expected. If there is a function you can’t map somewhere I haven’t found it and probably wouldn’t want to map it. The controls feel good, not gimmicky.

It’s responsive. It doesn’t turn on right quick, but once it’s on it goes.

The EVF is beautiful.

I initially intended to have AF-ON stay default and AEL be for EyeAF. However I discovered that you can map the center press of the joystick (what resets the AF point to center on canons), so I instead put the AF-ON function there (meaning I need not move my thumb after selecting an AF point), and put the EyeAF function on the AF-ON button as well as lens button.

That freed up AEL, which I have toggling between exposure preview and not, a function I had to tediously find in the A7R II menus. Combined with the custom menu, I can’t think of any reason I’d have to navigate the main menu with any regularity.

Congrats!!!  :)

Compared to mrk II, how is 6400ISO & 12800ISO? Thanks in advance.

A9 is the only body I have as FF. I'm kinda want 2nd FF body, too lazy swapping 2470 &70200 ;D , but want to see what a7s III has to offer. The a7r III looks very good.

So I shot a couple hundred family photos today, and lo and behold CameraRAW doesn’t support the files yet. There were a few at 6400 which look good in the EVF, but I’ll be in a holding pattern (not a fan of captureone, which does support it).
