Would the noise be much more pronounced in high ISO shots with the RIV?

Cheers, A.

I believe so, but that's where Topaz Denoise comes in! It's a much cheaper alternative compared to upgrading from an R3 to the R4.

Already got the Topaz Denoise, all of these Tamron shots went through it, but I guess I could be more "aggresive" with denoising...

I am leaning more towards RIV over RIII for bigger croping ability (as there is no TC for this Tammy), better EVF (mostly photographing with manual lenses) and better AF tracking. One huge reason for even thinking about upgrading is the poor battery life of the RII - I`m kinda tired of carrying 4-5 batteries with me

The noise is a little more, but if you downsample to 30-40 MP you cant notice the difference.


I didn't really notice any difference in noise in photos with the A7R3 and A7R4 when resolution normalized.

Here, only the A73 looks very slightly better, the A7R4 and A7R3 look pretty similar to me. DxO also shows less than 1/10th of a stop difference in high iso performance between the R3 and R4, though between the A7R4 and A73 the difference grows to 0.15 of a stop

To put another way, at high ISO, the resolution advantage of the A7R4 goes away, and you end up with an equivalent picture to the R3 and R2.
