DA*16-50 vs DA21 @ 21mm?

i have the DA21mm, and also a 18mm Sigma, and also an FA35.. and an FA43...

i figure i can sell the 18, 21 and 35, keep the 43 just cause, and purchase a DA*16-50 for trips and general use (in the future i plan on getting a K20D, so the HSM/SDM + weather sealing will match it nicely)

but i'm hesitant of ditching the 21mm,

does anyone have BOTH that they tested at 21mm f3.2 and on?

If you are interested in resolution, here is a comparison, both fully open:

thank you for the images, seems the 21 trumps somewhat (unless the CA's are the main reason for the DA's blurriness)

is this at F3.2? (edit nm read the comment)

Don't look at the colors. They are not true.
I did an auto-correction.
This is simply for resolution.
Both are shot fully open.

The main problem of the DA* 16-50 is AF inaccuracy.
This is a very serious issue. Many are affected.
There are many threads about this.
Try it carefully in a shop, before you buy one.

The DA21 looks quite impressive (discounting the fact that the DA is at 3.2, while the DA* at 2.8). I would at least wait to see comparisons with the Tamron 17-50 before putting down the money on the DA*. But then you lose out on weather sealing...

blende8 thanks again for your tests .... always very handy, makes me feel good about my DA21, even though it is kinda slow

gooshin there was a used DA* on the forums i think from toronto and craigslist for a good price

about the DA* focus concern, will the new K20d focus adjustments not take care of that?

theoreticaly yes, which is why this little tidbit does not bother me much at the moment.

I'd wait as well, if you don't have to have the new lens right now. Going by its reviews in other mounts, it could be verty good indeed.

If a zoom lens ever matched a solid prime lens in overall performance that lens would be a winner. If it comes close then it is a true performer, and I would expect the DA*s to be true performers.
