I think my Sigma EX 14/2.8 is capable of that shot.

Yeah, i was thinking to buy this lens too but im not sure whether the f2.8 can make a great DOF like the 24mm f1.8.

Do you mean out of focus background/bokeh. I cant recall a single photo I have taken with this lens where I've blurred the background but I found a photo with quite good bokeh from this lens over here: Flickr: Discussing Your best Sigma 14mm f/2.8 Image in Sigma 14mm f/2.8 EX
There is one with a ear of some grain in the foreground with the background blurred.

That shot is the equivalent of a 16mm f1.2 lens on APS-C. No such lens exists unfortuntely, not even close.

Wide and fast is best done with full frame cameras I'm afraid, that's their key strength over APS-C (that and 1 stop noise advantage).

A 14mm f2.8 is the closest I can think of for APS-C, an equivalent of 21mm f4.2 (that's almost 4 stops difference in DOF though ).

One thing you could try is to get a fast normal-tele prime, and then stitch images ala the "Brenizer Method" to get the same effect.

More samples here.

Cheers.

Get a Pentax A 50mm f1.7. It is manual focus but will meter through your camera and it is reasonably priced.

Sigma f. Pentax AF 2,8/14mm EX Aspherical (eBay item 350450498507 end time 25-Apr-11 02:59:19 AEST) : Cameras Photo

I have nothing to do with the seller. In fact, I think its daylight robbery, B&H used to sell new for about 850.

Anyway, your thread rekindled my interest in this lens, pulled it out and had a bit of a play:



You can see more samples in architecture section titled Queen Victoria Building.

This may be so, but you can still achieve the equivalent DOF, just with a shorter camera to subject distance.

are you sure you want a wide prime for portraiture? Usually a focal length between 50-135 is used. And Pentax sells a great zoom that covers that exact range with prime lens performance, the DA* 50-135/2,8
Love them for portraits! Men only, women became very sad once see it, they usually find themselves looking fat

You're about 3.5 years late for that deal.

Anyway, I see that you are going for SIGMA EX DC 10 - 20 F4-5.6, beware that you will get even less OOF backgrounds with that one.
