Sigma EX 70-200

Hello, im off to buy a new lens and i consider a Sigma EX 70-200/2,8 APO HSM DG Macro. Is that a good lens?, I have not seen any photos taken with a pentax camera and that lens..

Or should i wait for the new Tamron AF 70-200/2,8 Di IF Macro or Pentax SMC-DA* 60-250/4 ED that will be released in sweden sometime this fall.

might add that i will have a extender on the lens.

thanks

I say wait for the Tamron. I just think (and this my own humble, limited - experience opinion) Tamron is a sturdier build and offers a sharper picture.

The reason being that this lens doesn't exist in Pentax mount

I'd wait for the DA* or try to find a used EX 70-200 f2.8 (non HSM older design) but they are pretty difficult to find.

The Tamron is surely going to be a good performer.

I was verrry lucky to get my DG non-macro copy. It's out of production and all are in the hands of actual users, not shops. Fantastic lens other than the CA at f2.8-3.5.

Also, given that there's only another 2 months of autumn left, don't bank on the DA*60-250. We haven't seen any further news of the 200/2.8, 300/4 or many other lenses on the Pentax roadmap either.

the macro version still hasn't been produced/released for pentax mount (although it was supposed to be ages ago). You need to find a 2nd hand no-macro version.

I am not sure that it is safe to say that the Tamron is of sturdier build and offers a sharper picture.

The Sigma non macro is a solidly built, professional quality lens, with a proven track record of being tack sharp from wide open to whatever ap you decide you need.

While it is posted that there are CA problems at 2.8-3.5 by another user down the thread... I personally have never seen it on any of my images. Perhaps it is a copy issue, but certainly not an across the board problem.

I have to respectfully disagree. Don't know about EX short zooms, but the two Sigma EX "super zooms" are much, much better built than any Tamron zoom I've handled in my own hands. Specifically, the 70-200/2.8 and 100-300/4 EX lenses. My only macro lens is a Tamron 90/2.8 macro, and both EX lenses are better constructed. Just no comparison.

Now, the non-EX lenses...sure, I agree with you. But, not the EX lenses.

Steven,

I have to agree with you about the Sigma 70-200 EX DG 2.8 and the 100-300 EX DG 4.

These lenses are superiorly constructed and will withstand the rigors of professional shooting and handling. They are both extremely sharp and can compete head to head with anything Canon and Nikon and even Pentax can put out in similar focal lengths. I know there are hard core individuals out there that think only OEM lenses are worth mounting but the reality is that if you want a chance at sharp and professional quality images there other lens manufacturers that can deliver... and at a reasonable price too. Pentax makes it easier to go with other manufacturers these days because they produce next to nothing.

Ahhh! I long for the old days when Pentax rivaled the big two in lens diversity. Those were the days. Let's hope Pentax starts talking in two days and starts delivering something to mount on their cameras at the same time!

Stephen
