What options are there for a 35mm equivalent 16-18mm lens for a DSLR?
Assuming that I’m not being body manufacturer specific.

Sigma 10-20?

Seconded the Sigma 10-20 it’ rocks more than any other in that price bracket.

if you try to fill the frame with the rider they will crash into you 🙁

Is that from personal experience Simon?
I’m not that fussed about zoom – just looking for options for architectural photography (and I can’t justify a rising front lens), then it’ll come down to what body. I’ve been a Pentax type since ’81 so will have to have a look.

Is that from personal experience Simon?

yes, even at 18mm 🙂

Tokina 12-24mm AT-X 124 PRO DX II gets good reviews.

I’ve got their 10-17 fisheye and it’s great. Solid quality.

The sigma 10-20mm I had for a while didn’t focus properly. Not uncommon it seems.

not so necessary now that you can easily correct verticals in post processing

Another Sigma 10-20 user here. Never had any problems with focussing. It’s been great

Sigma 10-20mm is an ace lens, just don’t get sand in it like me.

Software below for doing just that.

Ptlens

Note that Ptlens can also take out lens distortion and vignetting

tokina 11-16

beautiful lens

f2.8 as well

Just bought a K20D – will think about the Sigma 10-20 lens (tried it in the shop and it seemed pretty good – quite a beast though).
Apparently they’re going up by £200 in the next month 😯

The Tokina 12-24 is supposedly better than the Sigma 10-20mm. Ken Rockwell has done a review of several wide angle lens’ although his ‘opinions’ do need to be taken with a pinch of salt.
The pics in his review do seem to supprt what he says though.

Sigma again

Enjoy gittin down and dirty

Another sigma 10-20 user here, very happy with mine.

MIlle says buy one.

If you’re using a Canon… then go for the 10-22mm EF-S, it’s an absolutely cracking lens. Bit more expensive than the Sigma, but it is a Canon… here’s some of my favourite MTB pics with it 🙂

Of course, it’s not just the lense… the photgrapher helps 😉 modest I know 8)
