Tamron 17-50 mm

Hi

I am planning to buy a Tamron 17-50mm f2.8 after reading lots of reviews on this. However, I am confused and unsure as to how many different models Tamron offers this lens and want to make sure I am buying the right one.

Please advice, the best model that I should look for in the tamron 17-50 for pentax. Also, how does this Tamron compare with the Sigma 17-50 - I can see the rating almost similar in the database but the Sigma seems a bit pricier!?

thanks, I would appreciate your advice at the earliest as I am now looking out for the black friday deals to snap a tamron.

S

Errrmmm as far as I know, there is only one Tamron 17-50 in Pentax mount. It has screw drive and it is labeled "Di II LD Aspherical (IF)".

It performs well optically vs the Sigma. The Sigma is more expensive due to the HSM.

I had a Tamron 17-50 but now own a Sigma 17-50. I didn't like the build quality of the Tamron and the Sigma definitely has better sharpness wide open.
If you only going to use it occasionally then the Tamron is a great choice. But if you plan on keeping it for a long time, using it as your main lens, then to me the Sigma is the best way to go. The auto focus is faster and quiet as well

Good luck with your choice!

Cheers

Thanks Randy, helpful to know. Will see if I can get this in a price I can afford. I know it is expensive than the tamron.

Interesting, this is exactly opposite of what I found. Must have gotten a bad one. Anyway my Tammy has been around the world and is still doing fine.
