It's one stop from a 2.8. If noise performance is better due to the larger sensor, it may function no worse than smaller sensored compact at a wider aperture.</p> <p>The new Sigma lens may be hard to pack. If it's too heavy for carry-on status, just put it on the camera and hang the camera around your neck. Act like it's really small and light.</p> I’m sure the f4 lens is a sacrifice to size.

The new Sigma lens may be hard to pack. If it’s too heavy for carry-on status, just put it on the camera and hang the camera around your neck. Act like it’s really small and light.

If they had gone with a more normal focal length, maybe they could've eked out a decent maximum aperture. And I don't quite understand how they could only get f/4 out of a fixed lens.</p> <p>Oh well. As you say, let's see what else they can do with the platform.</p> What a fucking waste. If they had gone with a more normal focal length, maybe they could’ve eked out a decent maximum aperture.

Oh well. As you say, let’s see what else they can do with the platform.

Maybe in the next version, they will have a faster lens. I am still looking for the perfect inbetween camera between a point and shoot and a full blown kit. The 5D is just too much sometimes but I want more than the SD900 can do.</p> <p>The 200-500 looks incredible but I wonder how much it is going to cost.</p> Eric, agreed that f4 for the DP1 is lame.

The 200-500 looks incredible but I wonder how much it is going to cost.
