OK you are all going to shoot me down in flames, but the sigma 10-20 is the worst lens you could buy for architecture, it stretches at 10mm and at 20 it might just work, I swapped mine for the 16-45 and that gives you the range you would need for architecture but you would be better with a prime lens like a 28mm a 30mm or 40mm, the 16-45 gives you all the options so I would go for that as I did.

Thinking of crowded cities like London, 16mm isn't always wide enough if you can't help but be close to a large building, and the 10-20 or 12-24 has less barrel distortion than the 16-45 or any standard zoom* at the wide end.

The perspective distortion ("stretch"?) of an ultrawide can be a disadvantage or an advantage, depending on what you want.

I suggested getting a couple of primes in addition to the ultrawide for when something longer is wanted.

Regarding the Tamron 17-50: It's great for the type, but I don't recommend it for the K10D in case an AF adjustment is required (common for this lens).

I have a Tamron 17-50 that was perfect for my K10 and is just about adjustable for my K20D. If it hits that sweet spot it is terrific.

I agree that for conventional architectural shots the 10-20 isn't the right choice - but who wants to be conventional

Make mine a 10mm prime

At the possibility of being shot down, the one lens better than the 10-20mm Sigma which is sharp edge to edge and has virtually no distortion is a 14-24mm f/2.8 and is full frame. Unfortunately it is not Pentax fit.

In that case I may as well suggest a Canon full-frame body with one of their tilt-shift lenses. Really the only way to do architecture.

Or perhaps a technical camera?

But, back to reality, get the DA16-45. A great lens for a cheap price. I have replaced it with the DA12-24 but it is now many times the price. And most of my shots are at 24mm anyway.
Listen to my albums free on BandCamp. Or visit my main website for links to photography, etc.

I can recommend the Horseman LE...

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

Possibly a ray of light for the true wide angle, distortion free need on APS-C?

This shot was a compromise as the 16-50 was not wide enough so had to use the 10-17 fish-eye.

Shift lens!



No, seriously, don't. I have one of the non-shift versions of that lens and while mildly amusing to play with it isn't the best £15 I've ever spent.
