I took a bunch of pictures of a tiger lily today with the Phoenix macro, DA 50-200, K-mount Tak 135 and the DA*50-135. They were all pretty boring, the focus wasn't always the same and I didn't think they showed much of anything other than I'm still not very good with flowers (and I have LOTS of practice). However, I did take this picture as I was walking down the street because I wanted to capture the bright colors. Then I did some cropping, and thought they were far more informative.

I hope that Scott does better than I have with showing off this lens.

K10, DA*50-135,f6.3, 1/500 sec, 135mm focal length. Full frame picture, just resized with someUSM added:

Notice on the full frame picture, the bottom of the picture? Here's a 100% crop with USM and a little photoshop to paint out the rest of the numbers:

P.S. - originally posted picture was too compressed - reposted with less compression.

Now that last crop is impressive. I am glad to see that Pentax appears to have a contender here.

Harriet, you can't do this to me! I'm saving up money for a new body and an expensive tripod, not for a new *-lens!

I thought that last one might get some people's attention - it got mine.

Kjell - you've got a number of top quality lenses, so this one shouldn't take priority. It isn't perfect by any means, and today I've discovered just how difficult it can be to shoot stuff with a razor-thin DOF. It does have significant amount of vignetting when you push the limits of the lens.

135mm, 2.8, 1/2000 sec. cropped to show what I wanted to capture, lightened because it was a bit underexposed, then resized in CS2. I think this one would fit right in with the "boring picture" topic.

The original, uncropped version, resized only in CS2.

Hi Harriet,

I noticed this yesterday, and wanted to confirm it before I posted any pics with this lens. The problem is that it's not consistent. Happens at f2.8 only, but not always, and only at the sides of a shot, not only at the corners -- I was thinking that might be the hood, since it's so deep, but no. . . Hmmm

I didn't think about the hood being the part of the problem. I've noticed it mostly when I've been shooting something in the sky - this picture and one of a robin on wires above me and I had the hood on both times, was shooting wide open and at max focal length. I hadn't thought about the hood - wonder if it's an influence with certain types of lighting, like in the sky. I didn't notice it at all when I was indoors or at the track field. More experimenting is needed, I think.
