Maybe it's supposed to be that all-important "prime-lens beater"; with exceptional performance across the entire focal range.

I for one would much rather have a faster 70-200. :ugh:

Either a Sigma with HSM for Pentax mount or the Tamron ... but we all know Pentax can make it better.

Can somebody clarify why this lens is so important to so many? It would/will make a fairly long telezoom. Wouldn't a fast standard or wide zoom be more important (like the 16-50 f/2.8).

Just wondering.

Personally the 16-50 *was* more important, but we have it. For me, I prefer to use primes in the 24-100mm (35mm format equivalent) area, but like a 2.8 zoom to cover that. Longer than that, I'd rather not use primes, because I find telephoto composition to be really difficult to judge with primes. Finally, 135mm as a long end is, for me, a far greater sacrifice than 4.0 as a max aperture. When telephoto, 4.0 is almost always fast enough for me. 2.8 makes it hard to get sharp focus in some cases.

So I think the desire for this lens is pretty well justified.

..if they ever make it.
