Initially, I was not too impressed as not having a lens hood seem to yield picture of flatter contrast. I bought a 67mm 3-stage lens hood, added a Hoya UV filter and tried it again on the weekend. The lens is pretty decent and it has a very usable range. Sharpness is decent. And it allows A aperture if you have the adaptall-2 pk/a adapter. I don't see a lot of discussion on this lens, but I find it a good manual zoom that covers a good focal range. It is on the heavy side and though it has a 1:4 close up, its minimal focusing distance is about 6 feet and I wish it is shorter than that.
Hiking & Portraits impressions:
- I love that focal range from 28mm to 135mm, better than 50-135mm or 28-75mm
- I find the lens focal range good for hiking and portrait.
- The focus throw is short, about 1/4 turn, and it allows quick focusing.
- 1:4 close up in the 28mm end is found decent in the center
- sharpness in good lighting is found great, indoor is perhaps a bit too slow
- minor zoom creep towards the long end for my copy
- a bit heavy but easy to handle
