Thoughts on Sigma 28-80mm and 70-300mm DL

I started looking to see what kind of lenses I had that may work with the K-r. These are the first two I came across and was wondering what your thoughts were on them. Nothing special but they are both macro with AF. The first is the Sigma 28-80 3.5-5.6. The second one is the Sigma 70-300 4-5.6. If I remember right I bought these new some years ago for a film body I picked up.

I tried them both and they seem to function ok. AF worked and macro too.

Yep, that's about right. There's nothing wrong with either, by all means use them. I have a similar 70-300, it only reaches 1:2 in its "macro" mode, which is more of a close focus than macro, but it can still do the job. It's a little more difficult to handle handheld due to the length when fully extended for 1:2.

It looks like the 28-80 you have also reaches 1:2. It would probably be easier handheld, though you'll have to get closer to the subject.

Bottom line is any K mount lens should work up to its original specs. Any A series will still have auto aperture, anything newer will still have AF. Experiment and have fun with any glass you have.
