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

OK I give up. How is a FF and APS-C sensor smaller than an existing Pentax offering or are you referring to the 645D?Your point about Nikon and Sony about to release cameras with sensors smaller than an existing Pentax offering proves what exactly? And is relevant to the Q how?
Only relevance is the different directions that the various manufacturers are going.
Have a look at the other forums, for some reason the majority of comments about the Q are negative. Why?
Any criticism's I make of Pentax are fair comments, IMO. You'll have to excuse me if I don't show any sense of remorse.

Maybe not gone. The recent issues with the K5 may have revived the lost market share situation.possible you mean gone are the days of lost profitability, and losing market share?
The Q may end up being a great success. What with Nikon and Sony about to release new 32Mp FF DSLR's and 24Mp APS-C DSLR's with the new Sony sensors, its good to see that Pentax are keeping up the rear with their miniature offering. Maybe the K4 will use the new 24Mp Sony sensor and the FF K3 the 32Mp Sony sensor?

For those that believe in magic though, why not put a mask over their APS-C sensor that has an even smaller window and they could have 5000mm lenses that started off as 43mm Ltds.

That aside, please be happy with your adapters and micro sensor once you purchase, I'll have to make do with a larger sensor and 400mm f/2.8 with or without TC's to get my image magnification.
Each to their own.
Best regards
great smiley by the way.

They have your permission "agreement" to use the images in any way they see fit. So do you. You "may" be credited but you will need that in writing. I have just agreed similar terms with Fremantle Council for street images.

Shocking weather in South Western Australia. Horizontal rain and poor internet connection. Fridge is fine and so is the wine.
