Please, help me pick a wide angle lens...
Mar 13, 2011

Here are the options for my precious K20D:

$650 Sigma 10-20mm f/3.5 EX DC HSM Autofocus Zoom Lens for Pentax
$480 Sigma 10-20mm f/4-5.6 EX DC J Autofocus Lens for Pentax Digital SLR Cameras
$700 Sigma 8-16mm F4.5-5.6 DC HSM Ultra-Wide Zoom Lens

$500 Tamron SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) за Pentax
$700 Pentax SMCP-DA 12-24mm f/4 ED AL (IF) Autofocus Lens
$480 Pentax SMCP-DA 17-70mm f/4 AL (IF) SDM Autofocus Lens for Digital SLR
$500 Pentax smc-DA 15mm f/4 ED AL Limited Series Autofocus Lens

I would like some help deciding which of these lenses to get. Here is my situation. I am wedding photographer (I started off recently) and I have the following lenses:
Pentax 50mm f/1.4
Pentax 35mm f/2
Pentax 50-200 f/4-5.6

I sold my kit lens and now I am looking for something on the wide end because... it is torture to shoot a wedding without a wide-angle lens.

What I like about the Pentax 17-70mm is that it has SDM and focuses rather quickly (which is important for me). It also has quite a useful range. It is also the cheapest one on the list and the financial side is very important factor in my decision.

Personally I like the Pentax 15mm f/4 more but ... I am not sure if its a good idea for weddings because its not a zoom lens (or may be it wouldn't be a problem if I buy a back-up body some time in the future)

Then there are the Sigmas and the Tamron. DPReview says that the Tamron 10-24mm is has much better center sharpness then the Sigma 10-20mm f/4-5.6... so I am leaning towards the Tamron. But is the Pentax 12-24mm worth the $200 difference comparet to the Tamron?
Anyway... HELP.
