Hey there,

I decided to add my testing scene for some of my Minolta AF lenses with the 42mpx Sony sensor.

I picked up 3 zooms and 2 primes to compare the portrait focal length between 100mm and 200mm.

The Minolta 135mm has really impressed me during this session.

Ehm, confused. The LA-EA5 supposedly does not work on the A7r2 or A7r3 - but you used the 42mpx sensor - that is the A99m2?

Also, in your samples there is no bokeh, which is something I would look at for a portrait lens. Even is you say the bokeh of the 135mm is "creamylicious".

Results are as expected btw. Nice lenses all. Maybe not super sharp as modern lenses, but very likeable. TFS.

Hey addy,

yeah yeah indeed I used them on A99m2. The thing is that accordingto these results I'm pretty confident that they those lenses will cope with the 61mpx sensor too.
==> True I will have to assess that too, that's a fact.

Good point: adding samples about the bokeh. I'm on it then ;)

What do you think to assess the sharpness if I added a full size zoomable version of the image ? :o

Thank you for all your positive feedback. I know what I have to work on

Looks like you mistakenly referred to the 28-135 as the beercan. Its nickname is the secret handshake.

But I agree: as far as budget lenses go, these work pretty well for portraiture. The 85/1.4 has dropped to ridiculously low price nowadays so it's almost a budget lens, compared to the hey day of alpha, maybe 10 yrs back.

The 100/2.8 macro works for portraiture - if you can soften the skin a bit. I use the Nik collection and it works wonders.
The 100-200/4.5 is also a decent performer and goes for almost next to nothing. The MFD is terrible, though.

I am not that much about detailed pixelpeeping, but I am sure some people would love the option to look at the sharpness in more detail.
Some bokeh samples would be nice.

re. the beercan: yes The Beercan is the 70-210/4, but the whole generation sometimes is called beercan, most notably the Big Beercan 70-300mm.

Like I did not say - nice write up (with some pointers )

if you don't mind my saying so, I far prefer the real world images you shared as compared to the dry flowers.
It's difficult for me to discern the IQ on those shots due to the lighting, the OOF areas and DOF.
Typically for such tests I've seen people use test charts or such that's set up parallel to the sensor plane so it's easy to see the center and edges and also how the IQ transitions between these zones.

I like the real world samples

I find test charts of limited use tbh. They seem to emphasise differences that are not field relevant and they are only relevant at the distance they used - but they never ever tell you the focus distance. Do not get me wrong, these test charts can be useful, but I tend not to look at them but look at the real life samples.
