maybe other posters lit him up for it, and he had to delete the comment, lol

in general, sony ff users don't usually think pentax for legacy glass, the pattern is to use whatever glass you had on your last dslr, which would be canikon for most people.

a-mount guys are thinking minolta glass, and all of the minolta 28/2.8 lenses suck, both af and mf, the 28/2.5 mf lens is the only good one... the minolta 35/2.8 primes are strong, but the corners never clean up like my m35/2.8 does.

Do you care about the quality of images with Pentax FF with film lenses or not?

I saw a lot of users complain that using film lenses on Pentax FF camera is ridiculous from other website.

For me, I don't care about it.
It is a load of BS. I use for wildlife 3 different lens (& occasionally TC) combinations.

The principle of these is a sigma APO70-200/2.8 EX released before the full frame (DG) designation I.e. A film FF lens, and have no issue with it or the two TCs I bought also both missing the DG (or FF digit all) designation

My other favourite is a Pentax SMC 300/4 with SMC-F 1.7x converter. Also only film design.

Lastly I am starting to use a Tamron adaptall 200-500/5.6 manual focus lens.

Except for some purple fringing on the tamron, which is manageable I have no issues with the quality of shots.

Newer designs are , well newer, but there is nothing wrong with a lot of the old designs either,

But having said this, I won't use a FF for wildlife, you crop anyways, I will use it for the wide end. There, it is a tougher call because there has been a lot of improvement in the wide area for lenses

Agree about FF for wildlife. For smaller birds, I often end up cropping the crop format.

Any full frame film lens which works well on the K5 I would expect to work well on the K1 since the pixel density is about the same. For example I expect the 24-90 F3.5 - F4.5 to work quite well on the K1.

that's ignorant rubbish.

i've put dozens of legacy lenses on the a7r, pentax at 28-50mm holds it's own... the only place that pentax is definitely weak is at 24mm on ff, for landscape use, but centered objects would be fine.

the longer pentax glass is probably good as well, i've just never looked hard at it, there is a lot more competition there.
Agree totally. Even the 24's could be good on the k1 depending on sensor thickness/nuances etc.

Loads of threads on pentax legacy glass and the sony a7 series.

To sum up:

Excellent: k28 f3.5 k35 f3.5 k55 f1.8 k85 f1.8 m50 f1.7 m100 f3.5 macro
Very good m35 f2.8 m35-70 f2.8-3.5 m80-200 f4.5
Very good for landscapes m20 f4 but too much distortion for architecture
Good m135 f3.5 and very compact

I am looking forward to purchasing the body for use with these lenses.
Yes they are not going to resolve as well as more modern glass but their colour rendition is wonderful and they are a joy to own and use.
