WTB DA* 16-50mm
Does the sigma also have better contrast, colours and bokeh? When people talk about IQ it comes mostly down to just sharpness so that's why i ask. :wink: When I did the test I did focus on sharpness, both the sigma and pentax's contrast was good, colour the sigma seems a bit warmer than the penta...

WTB DA* 16-50mm
It's by no means a bad lens, but in my view the 16-50 is rather better. 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 ...

WTB DA* 16-50mm
Sorry to come back to this topic once again, but http://www.robertsdonovan.com/?p=850 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, sh...

WTB DA* 16-50mm
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). Sorry to come back to this topic once again, but http://www.robertsdonovan.com/?p=850 You are Stefans love c...

Thanks for helping me make the choice easy folks...
I turn Pentax SR off and have it set to "1" on the lens for normal use or "2" for tracking birds in flight. With wildlife Alistair, you've just got to get the shot. Don't worry about using it wide open. F8 or 11 will often lead to another compromise, be it a higher ISO, or a too slow shutter spee...

I often use mine at 500mm, but if I get the chance to pull it back in to say 460mm, then this is possibly a greater benefit. My 135-400 sigma IQ is better at 350 than 400 even when 350 is cropped to give the same FOV as 400.

SMC-M 28mm f2.8 version II
As Matt has said this is identical to the Pentax-A series 28mm f/2.8 which is also the same optics as the Pentax-F version. I never thought it was as good as the Pentax-A 24mm, but it didn't cost anywhere near as much. It's much better than stuff like the Sigma II 28mm f/2.8 which some people pra...

SMC-M 28mm f2.8 version II
I have the SMC Tak 28/3.5, K28/3.5, M28/3.5, A28/2.8 and the Vivitar 28mm/2.8 close focus. I keep meaning to do some formal(ish) sort of test of them but haven't managed to find the time as yet... Usually the Tak gets used on my ES/ESII, the K and M on my K-mount film bodies and the A on the K20D,...

Lens for Street Photography
I'm looking around for a wide angle prime lens to use on my K-7 for Street Photography. Something around the old 28mm film camera lens (say 18mm on the K-7). Compact, preferably not too slow & doesn't have to be auto focus but auto metering would be handy. I've considered the DA 21mm f3.2 & the ...

da15 produces great results even wide open, no worries. but there is nothing 'not to slow', compact and reasonably priced in that segment. maybe da21 is the closest match, or manual focus 20mm? i use old manual focus 24/2.8. a bit narrower but very good results. and not hard to find 24/2 if you wa...

Lens for Street Photography
I think when the reviews say it's best stopped down they are thinking of landscape work where you want edge to edge sharpness. But do you want this all the time?? I can see uses for that, i.e archiving pics, but I've seen some landscape pics which look great taken at wider apertures where the nar...

Don't forget the Voigtlander 20mm. It's f/3.5 and manual focus but it is small and highly rated by all accounts. Probably a bit more expensive than the pentax 20mm though.

I also use the Sigma 24mm f2.8 Super-Wide II for street photography, much smaller but a bit longer than you say you are looking for. That would have been my suggestion, I have both the AF and manual focus versions, but as you say too long. It is decent wide open at f/2.8 though. John
