Congraduations to Kerrowdown for winning this week's challenge; the next one is yours!

Edit: Kerrowdown cannot run next week's challenge, so since wissink has already offered a funny bird shot, let's go with that.

Edit: Comparison of MTF.

Finally, it's interesting to note that it is an SDM lens, not a DC lens, and that the press release describes it as a "new-generation SDM".

Pentax A135/1.8 vs Samyang 135/2
Posted By macTak

The reviews for the Samyang have been nothing short of exceptional, finding it every bit as good or better than the Canon 135L. Plus the Samyang is shockingly free of CA, which certainly cannot be said for the A135/1.8. Frankly, I'd go for the Samyang, and that is even if they were much closer in price; at the moment it is one of the very best (optically) lenses available for Pentax.

Nor is it working for me in the UK. Traceroute shows it stopping at an NTT IP address in the USA, so it makes sense that it would only be out for part of the world.

Weird Bokeh with 40mm Limited vs. XS

They are both 5/4 (Unar Elmar hybrid) designs, but there are definite differences in the shapes of the elements that would unquestionably affect their characteristics.

Weird Bokeh with 40mm Limited vs. XS
Posted By macTak

That Bokeh is the result of over-corrected spherical aberration. Both the Ltd and XS versions have the same optical formula and should therefore be the same in this regard. From my experience with lenses that have some over-corrected spherical aberration (e.g., M35/2), it only occurs (or at least is noticeable) in a certain range of circumstances--for instance wide open when focusing to within 2ft and then with a background that is significantly behind the plane of focus. Based on the samples of the DA40 you link to, the range of circumstances seems pretty similar. Depending on your shooting habits, it may or may not be prevalent, but generally is not catastrophic even when it occurs as only very tight crops/very large prints will make it visible.

A very intersting lens idea. I wonder how the DA15 or another UWA would perform with extension tubes in comparison to this lens.
