Thank you

...to everyone for your helpful and prompt advice.

After reading what Lowell had to say, I realised that whilst the 16-45 may have been the lens to have for my most recent trip, it might not fit in with a long-term lens strategy so well.

Am now veering back towards something going out to 70mm at the long end. Possibly the Sigma 17-70, or maybe even Tamron 28-75. If I get the latter, I still have the kit lens for wider stuff, until such time as I can afford an ultra-wide. Which will not be anytime in the near future, unfortunately, unless I win the lottery.

I'm in the same situation as you are and came to the same conclusion. Pentax now has the 17-70SDM which throws another wrinkle in the decision but the pricing on the Pentax has my $$$ marked for the Sigma.

The Sigma is a full stop faster on the wide end and only ~1/2 stop slower long, is a Macro lens and has a better warranty. The Pentax is SDM but the Pentax SDM motors are not ring types and apparently offer no focus speed/reliability advantage.

Some folks have said that the Pentax is sharper wide open vs the Sigma corner-to-corner. From what I've seen the Sigma is plenty sharp.

Mr. T. I have both the Sigma 17-70 and the Tamron 28-75 (LBA is a wonderful thing) and quality wise I think the Tamron is a better lens. The difference between a constant F2.8 and the variable aperture of the Sigma is a big deal. Also the Tamron is both lighter and smaller, and to my eyes sharper. However, the zoom range of the Sigma is handier. The last fact is a great rational for owning both if you need to explain to someone

NaCl(of course trying to explain LBA to non photographers is very difficult at best)H2O
