[quote:3496ace15f="vic cross"]My experience with the colors of Tamron is bad, actually very bad.
I had the Sigma 10-20 for a long time, and the DA15mm for a long time. The Sigma was very nice, perfectly sharp enough across the whole frame; a bit stretchy in the corners but I think that's just a fact of life with 10mm. I didn't notice anything untoward about the colours. There was a bit of vignetting which sometimes made vegetation look too dark at the edge of the frame.
The DA15mm gave lovely crystal clear images and colours - the edges were a bit blurred/OOF on close inspection (even if the centre was perfectly in focus) but overall the images popped.
But for versatilities sake, if I was choosing now it would be between the Sigma 8-16 and the Pentax 12-24.

You should throw the Sigma 10-20 into the mix. It's a cracker. I'm sure anyone on here who has one will tell you the same. It has a very good reputation and I love mine.
CHEERS Vic.
My main concern with a third party lens is mainly the colors (and sharpness).
My experience with the colors of Tamron is bad, actually very bad. I own the Tamron 70-300mm F4-5.6 AF Di LD Macro. The lens is sharp but the colors are very different and far from the colors I get from my Pentax lenses. I work only in RAW and I have to work double the time on images taken with the Tamron to get the right colors. It can be very interesting to see compare images taken with the 2 lenses I mentioned in the original thread post or images compared to Sigma wide zoom. I understand that the Sigma colors are a bit cold.

I am out for a new wide lens. The 2 lenses which made it to the top for me are
Tamron SP AF 10-24mm F3.5-4.5 Di II LD
and
Pentax smc DA 15mm f/4 ED AL Limited
I sure know they are not of the same category and I am fully aware of the differences between them.
I read a lot on the net and compare sample images - that's the best one can do in order to get information and decide.
The important factors for me are sharpness and true to life colors - and here is where I ask for advice.
When I compare full size images from DP Review - I tend to think that the Tamron lens is sharper than the Pentax.
Is it true?
How good is the Tamron lens in terms of sharpness and colors?
How do they compare?
Does anyone have any experience with both?
Samples to compare?

I have tried again with the clarity and contrast in ACR - it does not come to the same quality as Capture One 7 Express! Download a trial version from their site and try it for yourself. The difference is clear and nothing but amazing.

"I an using Adobe CS6 with ACR and Capture One 6 Express."
The 1st one in each looks a lot better/sharper so is that
the Adobe one? That's the way you started off.

I an using Adobe CS6 with ACR and Capture One 6 Express.
Just downloaded a trial version of the new Capture One Express 7.
I am so impressed how the Capture One manages to pull out small details that ACR simply cannot see! Colors are also great.
The last 2 samples are from my Pentax K-10D and the rest are are RAW samples from the net. All the samples are 100% crops - I think you will be able to see the difference quite clearly...

BTW, the lens arrived and I can already say - it's a great lens.
