My sigma 100-300mm f/4 APO EX DG has been putting in a stellar performance on the K5IIs, though the AF is still a bit twitchy.
Great bird shot. Very sharp and really nice bokeh. Just wondering if you have tried the sigma 120-400?

Picked up the K-5 II s at the weekend (part exchanged my K-30) and these were from first outing with it yesterday with DA* 200.

From my recently acquired Sigma 8-16mm f/4.5-5.6 ASPH DG:



Though be warned this lens is a real Moire machine when buildings are involved.


There are fine gratings over the stained glass windows of this church which cause some pretty bad moire*, so I stopped down to f/14 to eliminate it: you can also get maze artefacts as well which are even more annoying.

*I use this building for the express purpose of Moire testing, those gratings have never let me down.

DA* 60-250 @ 250, ISO 80, F/4, 1/2000. I'm trying to decide if I should keep the 60-250 or trade it in for a DA*300.

Since we don't hear from Rupert much anymore, I figured it was my duty to bring back some tree rat love. Yes, they are troublesome rodents. They are also so damned cute. In case the exif doesn't make it: K5IIs, DA*300, 1/350s handheld, f/6.7, ISO400
