Pink on Green

This is a photo from my new Pentax 50-135 f2.8 DA* lens. I love the lens already. It could be a little longer at the long end, I think, but the image quality is exceptional. I wandered around in the yard for a bit, shooting this and that. It's no macro lens - minimum focus is on the order of 3 feet or so - but it still does an admirable job of capturing anything from 1:4 on up.
The colors the lens produces are very contrasty and saturated. It focuses nearly silently, although it doesn't seem any faster than the screw drive lenses I have. The bokeh is usually smooth, although its character changes significantly depending on the type of background. Flare is very well controlled - I shot up through the tree limbs at the sun, got a small starburst and otherwise good contrast near the places the sun poked through.
All in all, I think it's well worth the money you spend on it. If you're shooting Pentax, get one!
