WTB DA* 16-50mm

Yup, the DA17-70 is a fine lens indeed... just got my hands on a DA*16-50 and there is a marked difference in construction (more solid), focusing is quieter still and easier to manual focus (the focus throw is the same, but the 17-70 is very loose in comparison with no damping), resolution is astounding even at f/2.8 (but focus is super critical of course).
Already I can see I should have bought one much, much sooner

Just need to do some AF testing on the K-5, and will try and keep you posted with more concrete comparisons

Sorry to come back to this topic once again, but

I've owned my 16-50mm SDM since Feb 08, broke it in Feb 11 and replaced it with a new one. Before I bought the replacement, I bought the new Sigma 17-50mm OS HSM so I now have both.

The Sigma is a very good, sharp lens and I think the OS is better than the SR in my K7. It's shortfall is that missing 1mm at the bottom end.

My 16-50 is also very sharp and I have yet to see CA.

Real world results seem different to reviews.

It's an excellent optic.

Best regards

Over time I have had the 16-45mm, 16-50mm, 17-70mm and Tamron 17-50mm.

The only one I still have in my collection is the DA* 16-50mm (and a recently purchased 18-135mm for walkabouts).



You are Stefans love child and I claim my prize.

SO you pefer the sigma 17-50 or the pentax 16-50?? if you have to choose one? in term of IQ I mean, forget about the weather seal.

K10D can you let me know how the bokeh comapre between the two as well. Thanks

I can't say I've looked hard enough to tell. I will do some compo shots and post. I use the 16-50mm more than the Sigma for the extra 1mm. I did post some with the SDM here link

These two with the Sigma







and my first 16-50mm SDM RIP
