Anyone out there own or used one of these beasties?

Is it worth the increase over a Pentax DA* 300mm F4.

Ive heard good reports from canon shooters who use this lens. Its the only way off getting 300mm 2.8 brand new in a pentax mount.

But it depends what you are shooting and whether you need the speed of a 2.8 and the extra weight that comes with it when compared to the 300mm f/4

One advantage of the sigma is the 1.4 x teleconverter will work with it making an f/4 400mm lens and keep autofocus.

I borrowed a friends Sigma 300mm F2.8 in Pentax mount, AF is faster than DA*300mm but I found the images to be slighty soft at F2.8, I'd say when stopped down to F4 images were on par with DA*300mm at F4. The Sigma is quite a lot bigger and heavier than the Pentax too.

The only advantage with the sigma over the pentax is slighty faster focussing so I decided to keep my money in my pocket and stick with the DA*300mm.

Well, not the only advantage - being able to shoot, albeit softly at f2.8 300mm obviously counts for something.

Has to be said though, 1400 (at SRS prices) is a hell of a lot of money to pay for those two advantages.

I think Timothy W meant a 1,400 price difference between the two.

I've captured a few half decent sport & wildlife shots with my kit 50-200 zoom, and my 600mm Sigma mirror lens has the reach, it's just far too slow at f8.

It's all a bit "pie in the sky" at the moment but if things go to plan over the next few months, I might be able to treat myself. Fingers crossed!

Why not get the da* 300mm from srs, try it out and if you need faster trade it in for the sigma...

I'm beginning to think along those lines.

Probably cheaper to just rent the DA* from SRS for a week.
