I have to ask, given that the 40 XS and Ltd have the same optical formula, how can the Ltd be so much less sharp than the XS? And is that really a solid basis to say the sharpness of any sample of an XS is better than that of any sample of a Ltd? At least, that's how I interpret the marks they get.

I think the review is well-written and quite comprehensive. Too bad the 40mm limited seems to have been a bad copy. The only thing I would like to point out is that the sharpness test with the landscape seems to have been taken in a desert, which is not good for a lens test - bright lights, not much content in the frame, a lot of hot air rising from the ground, creating distortions. Of course, if that is where the reviewer lives, there isnt much to be done. Maybe early morning shot of a straight street in a city?

Could it not just be sample variation?
Yes, the reviewer even states they had better performing 40mm ltd samples in the past and that there is probably something wrong with the particular copy he has.

Cool Adam.

Now get a good copy of the DA 40 LTD and do one of these for the 40 XS, 40 LTD, and 43 LTd. :HeadBanger:

However, the true normal focal length, i.e. the one that most closely approximates the field of view of the human eye, is 43mm. This is why Pentax released...

Yeah, unfortunately it was the best position nearby to get a full infinity shot without things blocking the horizon. I did do the second field test with a closer subject to try to avoid the heat shimmer, etc.

Thanks for the comments, everyone. And to the person who pointed out the front focus/back focus discrepancy in the review comments on the main page, yeah... simple typo. I'm sure Adam will fix that one.
