 p.3 #3 · p.3 #3 · Is the Sony a7R IV the best value full-frame camera on the market? | |
I switched from R IV to R V (I can save 20%+ on tax back then was a big factor), I'm not a pro, I shoot random things, landscape, cityscape, pets, recently moved to another country and I can see more birds and insects (but less cityscape), maybe I can sometimes see fox, deer or smaller animals.
R V has better viewfinder but I don't find the lower res of R IV finder limiting.
R IV interface is not slow (but I came from R II) but R V is better.
For cityscape (especially modern Metropolitan), lossless compressed raw is good. Sony lossy compression can affect very high contrast scenes (like lights on top of skyscrapers against dark sky), you probably won't see artefacts often but it does happen. It also affect highlights recovery (which is IMO important for cityscape at night).
AF of R V is better than R IV, I don't have a lot of experience with R IV but when shooting my dog running towards me R V gives much more keepers (using Sigma 135/1.8).
I prefer the flip screen of V to IV since it's better for tripod use in portrait orientation.
IBIS is also noticeably better.
For stars, I'm not sure much has change but unless it's for scientific use it's not really an issue. I have shot landscape with Milky Way and none of my Sony was able to eat that away. Even star trails are fine too. I lost track of that issue.
Is Sony still developing and updating the firmware for the IV?
sadly no, I think they probably can add lossless raw but that why I switched
I don't convert ARW to DNG, but I did that from time to time when I was shooting uncompressed raw with R II / IV. I failed to see any benefits in converting lossless compressed raw to DNG.
When shooting an auto exposure bracket and long exposures, will the a7R IV take a dark frame for long exposure noise reduction?
dark frame for noise reduction is optional, just like any other Sony bodies I have used.
Is rolling shutter an issue...
Of course it's an issue, that's why they made stacked sensor for A1 and global shutter for A9 III. You just have to work around the limitations.
The sensor of R V is probably slightly twisted from R IV, they are very similar, I don't think image quality has any meaningful changes. But R V can shoot 8K video and AF points are slightly different.
I think Z8 is a good value but I'm ex-Nikon shooter so maybe I'm biased.
CFexpress type A used by Sony is not great value wise.
Value is very subjective, one is clearly better in every way so there are always tradeoffs and only you can tell what's important to you. I still keep a A7R II since I consider it great value (although I can't reliably use it for pets and wildlife, birds etc). I also think 42mp is more efficient than 61mp. Some might say R III is great value.
