Lately, many people have pick up the new k10d and started using it with some tiny primes like the DA21. It seems that some are complaining that there is a auto focusing problem/issue with this combination.

The "Online Photograher" blog describe this problem. http://theonlinephotographer.blogspot.com/2007/01/pentax-k10d21mmda-autofocus.html
And the DPreview forum also have many post on it.

I am wondering if anyone of you out there really has got this auto-focusing issue with DA21? Like not able to focus to infinity? out-of-focus when wide open at f/3.2? poor bokeh? Can those DA21 owner please share your experience... thanks!

I did mount this lens at CP to try it out. My impression is that it is a very sharp lens and the only thing I don't quite like is the color rendering when compared to FA lens. So what is wrong with it? Anyone?

I agree w/ Lee here, better buy this lens in a local store and test it out, make sure you get a good one :)

I had one on my Ds for a short while, quite a nice lens, sharp and contrasty. Color is abit different just like most other DA lenses, but for a wide angle lens, shouldn't be a problem I guess. Price is quite reasonable too. If you need a wide (but not super wide) angle lens, this is a great option.

Of course there is an FA20/2.8 and A20/2.8, both are great lenes. Hard to find though.

Cheers!

Fengwei, but you didn't have any auto-focusing problem with your DS /w DA21 back then when you had it? The DA21 is so cute for the size of it and it will serve its purpose as a carry everywhere lens that is wide enough for general.

Sometime, there isn't a chance to test the lens when you purchase it through mail order/ebay. I own 13 lenses and none of it is purchased in singapore.

Any DA21 owner out there with problem in auto focusing?

I didnt notice any autofocusing problem with mine, but I didnt do any chart test but real shootout. It worked fine on my Ds.

Don't have it anymore, cant test it on my K10D ...
