Da 12-24 or sigma 10-20 F3.5

i`m going to buy a wide angle lens. do you have any sugestion about Da 12-24 and sigma 10-20 F3.5. sigma 10-20 is more wide and i find many pictures in 10mm on 500px, i thought it should be sigma 10-20 but not sure about that. anybody ever used this lens and how is the quality compare to
da 12-24 ? Thanks!

I have previously owned the Sigma 10-20 f4-5.6 (in both Pentax and Nikon mounts) and the currently have the Pentax 12-24; but not had the Sigma 3.5 version.

The Sigma 10-20 f4-5.6 is one of my favourite all time lenses, and I understand from the reviews that the f3.5 version is an improvement.

What I would add is that I have been really very impressed with the Pentax 12-24 although I have yet to really test it out completely. The constant f4 is a bonus but you will have to pay more for this than for the Sigma.

If I were you I would be tempted to do what many of us have, start with a used Sigma 10-20 f4-5.6 and then if wide angle is for you then you can always upgrade.

Hope this helps,

There is a good looking 10-20 Sigma for sale in my local camera shop. Camera Box in Kettering. They have a web site so I'm sure you can find it. I have one and I love it. So do most owners from what is said on this forum CHEERS Vic.

Thanks, Andrewa. i had a da 16-50 and always found 16mm is not enough for wide view.it`s a good idea to start with 10-20 F4-5.6. it`s much cheaper.

i find the website but do not see any sigma lens.

I have read a lot of opinion that version 3.5 has more discorrections compare to old version 4-5.6

Over here is test of 3.5 and compare to old version

Hard to go wrong really!
I have had them all! (no surprise!)
If you want staggeringly wide Go sigma 8-16mm
Want cheap and use filters go Sigma 10-20mm F4-5.6
Want a bit faster go Sigma 10-20mm F3.5
Want the best?
Go Pentax 12-24mm F4, it is the best corrected (optically) of them all.
What CA there is, is very easily corrected and from my point of view as a Landscape shooter it is the sharpest across the frame with the least distortion of all those I have mentioned.
They are all very good and your spoilt for choice...
Just pick the one that suits your budget and be happy!

Also look at the Sigma 12-24mm. Usually overlooked but I went from the Pentax 12-24mm to the Sigma (mainly due to usage, the Sigma was a lot cheaper and made more sense as I rarely used UW).

I have to say it's an excellent lens and also has the benefit of being FF compatible so when Pentax release their FF body in 2025 you will have an extremely wide lens.

Thanks Jules, that`s quite helpful. cant image you got all of these. the
only thing bothers me is 82mm diameter of sigma 10-20 F3.5. i got a progrey filter holder system and can be work with 77mm polarizer.if i turn to 82mm, the 82mm polarizer must be another big cost. DA12-24 in uk is really expensive, maybe i should asked my friend buy one from Japan or Hongkong.

some probable words about FF body released this year, hope they can do it soon. otherwise when i tired of zoom lens i will get a sony a7 to fit the beautiful FA limited lens.
