Haven't done a Buy Me Now! thread for a while, but I simply have to tempt you all with the new Sigma 50/1.4 Art.

Comparable in optical quality to the ludicrously overpriced Zeiss Otus, this has the added benefit of autofocus. Fast HSM drive autofocus at that.

This is still £850, but . . . . not available in Pentax K-mount yet.

Have a look at what people are getting out of this thing on Flickr . . .

Calumet are having opening days this month. If you live near a store maybe you could get to feel one and test drive it.

Free sensor cleaning too, if you need that doing.

Would you not consider using a k mount adaptor?

Don't order from them online, their US side recently went pop.

MJP...To me Sigma have always made a great lens for the money one pays
and...some of their lenses are even better than Nik's or Can's are. I can
vouch for that in the case of my Sig 24-70 @2.8 which is sharper than Nik's.
Granted there's a bit of distortion at the wide end however this doesn't
bother me one iota. And that's all that one could say "wrong with it".

I have Nik's 17-35 @ 2.8 and only wish that Sig had their 18-35 @
1.8 on the market before I bought the Nik as I'm not concerned with a
silly millimeter difference at the wide end.

I'm sure the Sig 50 @ 1.4 will be a winner and judging by the pic below
it's sure to be one...

In the mean time...I'll just have to be content with my 58 @1.2

when I need to use it...

I used the previous model Sigma 50/1.4 on my Sony A900 and I loved it. I only needed to make a slight back focus micro adjustment to get absolutely fabulous pics. The color was much better than the Sony 50/1.4, the images were much sharper and the bokeh was superb. I have since move on to a Zeiss 50/1.4 with my A99 but I will suggest the Sigma 50/1.4 to anybody who wants an excellent lens for walk around and low light shooting at an excellent price.

Like Munkeybooger I use Zeiss. Have the 35 f1.4, 50mm f1.4 and 85 f1.4. All MMG C/Y on my 5DMK2. Incredible lenses. The 35mm has become expensive but the others are very affordable. But, THE lens, without a doubt, is the Zeiss C/Y 35-70mm. Cheap as chips and even Contax state that it surpasses their primes. And it's a macro to boot.
