Sigma 10-20mm vs Tamron 10-24mm

The Sigma runs $499 and the Tamron is $374 after $100 mail in rebate.

Which would you get? I've read the reviews, looked at the lens clubs, and still can't make up my mind. I'm looking for a good travel/landscape lens, something I can use to take creative pics while hiking, and am not really much of a pixel peeper or stickler (not nearly as much as some people here...I see a great looking shot and some of you find a million things wrong with it ).

Will I be sorry if I go for the cheaper one? I do have the Tammy 17-50 2.8, and LOVE it.

I bough the Tamron, and I was happy. I use it extensively in my summer trip in Greece

Note that the Tamron 10-24 has nowhere near the reputation of the 17-50. The fact that you love the latter should not guide you in this decision.

BTW, which Sigma 10-20 do you mean? I went for the constant aperture f/3.5 one. I believe it is superiour in terms of IQ to the Tamron and I don't think I'll ever miss the 4mm at the long end. I rarely use my Sigma above 16mm but your milage may vary.

I'm talking about the Sigma 4-5.6 EX DC. I've read there are a lot of QC issues and people are getting bad copies. That alone makes me weary. Then I read that the Tamron is pretty soft in the corners, but in real world application most would never notice it (and you could always crop a little). I don't mind paying an extra $100 for a superior lens, as I want the nest possible landscape shots. I guess the fact that the Sigma club thread is HUGE says it all...

What other choices do I have for ultra wide angle in the $500 or less category? I really only need 10-16 range, non fish eye.

Not sure why this recent thread was not mentioned, but it includes picture results from both lenses.

If you buy new, just return it until you get a good one. The Pentax 16-50 also had QC issues. Sadly, it happens but as long as manufacturers respond by giving you a new one, I wouldn't be concerned.

Have a look at the thread tomwil pointed to. The Sigma is sharper and has the better bokeh. The images were made at different f-stops, though.

I don't know about other choices, except the Pentax 12-24 which I believe is overrated by Pentaxians. The same lens (Tokina 12-24) is considered to be competent but not outstanding by Canikonians.

I don't have the time and patience to return lenses multiple times. If it's not good the first time, I don't really want it. Still torn... Seems like the Tamron is at least on par with the Sigma, and better in some respects, for over $100 less. I'm checking out Ebay for some used ones before I decide...

Thanks for the replies!

I have a feeling that Pentax owners overrate it because they often describe the 12-24 as a kind of marvel while the same lens (available through the Tokina brand) receives reviews from Canokians that attest it competent performance but also weaknesses (PF). It seems that non-Pentaxians are less enthusiastic about the lens. I'm sure it is good but I don't believe it is the marvel Pentaxians often describe it to be.

That's not the common wisdom and the images in the other thread speak a different language. However, I'm sure you'll be happy with the Tamron as well.

I understand what you mean by this although there is a logical reason behind it. besides, how many UW zooms does Pentax has to offer? there is only one, and other 3rd-party alternatives. Pentax users dont have that luxury that Canikonians have. out of the possible UW zooms that are K-mount compatible, the best one is the Pentax, next to the Sigma 12-24. so it is true if we are going to look at it from a Pentax user's point of view and lens availability.

Has anyone compared the Pentax 12-24/4 to the Sigma 10-20/3.5?

none that I'm aware of. although I have heard that the only thing that differentiates it from the older Sigma 10-20, is the aperture speed. other than that, it is practically the same lens. the Sigma 8-16 seems to be a very good lens. so this can be a better alternative for someone looking for a much wider FOV. it doesn't appeal me due to focal length shortness, but resolution wise, it seems as good as the DA12-24. it seems to have better CA control as well. I would say it's a toss-up between the two lenses and would be decided by focal length needs.

QC is a potential problem with the Sigma 10-20 4-5.6. However you'd really have to buy several (at once) and compare them. Otherwise you'd probably want back one of the ones you'd returned.

I don't have experience with the Tamron, but I'm not sure this isn't a general problem with almost all lenses. It might just show up a little more prominently in the more radical designs like these.
