DA 18-135 First Photo Samples

Some photo samples are posted in a thread at the Chinese Xitek Pentax Forum, here it is:-

http://forum.xitek.com/showthread.php?threadid=790281
(in Simplified Chinese)

The photos were taken at the Photokina exhibition hall indoor, you can find downsized images taken at 18mm f/5 and f/5.6, 31mm at f/5, 68mm at f/4.5, 78mm at f/5.6 and 3 other samples 135mm at f/5.6 (here for a middle-distance scene, here for testing the bokeh and here for verifying the skin tone).

After viewing, I do have some good impressions about the IQ of this lens. There is no obvious CA seen, the photos are considered sharp with good contrast (despite they are downsized), bokeh is nice and colour response is okay (the actual colour accuracy/tendency cannot be judged exactly for those indoor environments with artificial lightings anyway).

The barrel distortion at 18mm is a bit dominant but it would be of no surprise for such long-range zoom in 7.5X, nevertheless.

Your samples look nice, with strong textural feel and good skin tone. Thank you for sharing!

Would you mind including them in the text (ofcourse with my (C) still in it)?
I wouldn't mind at all (if you don't crop out my logo! :-P)!

P.S.: I do have some DA L 35mm shots as well!

That's a good idea and thanks for the samples indeed. I suggest that you could email all the samples to me and then I shall upload to my Photobucket before I link them in post(s). Of course, the watermark and copyright info will not be removed and I think I should acknowledge you as the picture provider as well.

As for the shooting information, I believe that the key EXIF data are still there, which should be kept intact.

Very good lens people should be happy with it...for most it will be all they ever need. I would plan on getting one for even shooting.

"The barrel distortion at 18mm is a bit dominant"

There is no distortion at 18mm. Loot at the pillar at the right side of the first photo. The ceiling grid was not straight and it is not possible to make any conclusions of it.

There is no distorsion correction in this photo. I know because I too it.
