I was wondering which set would give me more magnification.
A99II with Sony 70-400G, or a6400 with Sony 70-350G.
Since I was not able to calculate it ;) I made an experiment.

It turned out that after cropping identical crops 100% (with a longer side of 1024px), both images are identical.
Quality at higher ISO speaks in favor of the first set, while the second set is significantly lighter.

I feel the picture on the right is sharper - might be just better contrast, but still.

I did a quick comparison with the 70-400G and 70-350G at f/8 a few months ago and found the 70-350G to be sharper in the centre. That was at shorter distances but also 400/350mm.

Edit: just realized the 70-400G is basically on an 18mp APS-C camera. That might be the reason for the difference? I compared them both on the A6400 and still found the 70-350G sharper in the centre.

In my opinion, the sharpness in the center is similar.
However, at the edges the 70-350G is much better.
Perhaps some of the differences are due to the fact that I take pictures in jpg and there are different degrees of sharpening in both cameras.
Edges. 70-350 on the left.

Are you trying to decide which to buy or do you already have both and are trying decide which to use? the A99ii is just under 18 MP when in APS-C mode and should have a crop factor of just over the standard 1.5, closer to the Canon 1.6.

I have two. I was just curious. I mainly use the smaller set.

Don't forget that at distance atmospheric effects will limit resolution and contrast on both. Also, if you ever do close-ups such as candid portraits, you may find the long MFD a problem. I used to find a 200mm prime worked better than zooms.

If you mean the Minolta 200mm APO then its MFD is the same as the Sony 70-400G (1.5m). The small Sony 70-350 lens has an MFD = 1.1m
Of course, the Minolta 200 will be better for portraits due to the F2.8. Recently, however, I have used this lens less often. It has too much aberration and the AF is not so sure.
