This test is with my six week old Sony A7iii, Sony adapter LA EA4 & Minolta 35-70mm f3.5-4.5 zoom. These shots were all taken hand held at f8 and 1/60 sec. I used a Godox TT350s flash set on TTL. All are from jpeg out of the Sony set at large & fine. I used the jpegs as I could see only a tiny bit of image degradation using jpeg. This is beginning to be the norm with this camera. When I was using my Nikon D5500 or D750 I almost always shot raw and edited with Lightroom CC or CC Classic. I did that because there was a substantial benefit to do so. With the Sony A7iii the jpegs come out so good there just does not seem to be a point to store the bigger raw files. When I say the Sony jpegs are good I mean both image sharpness and color.
This lens I got for free. I bought a Minolta 70-210 from eBay for $32 a couple of years ago to go on my Minolta 600si film camera. I looked up this lens on the internet and it gets some good ratings. Cheaply made but it is sharp and works well when you get a good sample. This should be evident from looking at these photos I just shot today.
I used these settings to get these shots. Single shot, DMF focus, center focus area, 0 exposure comp, auto ISO, center teetering, AWB, std color, and A mode set at f8. The camera chose 1/60th.
I have found with this lens that if the background is very busy and bright the bokeh can be distracting. But this is no Zeiss Otus or Sony G master lens.
This lens works very well with both the LA AE4 adapter and the Godox flash. I set the flash on TTL and put on a light diffuser that Godox included when I bought this flash two weeks ago.
These lenses can be bought at a low price and if you are looking for a budget zoom with this focal range I recommend it.
