Tokina 11-16mm f/2.8

joosay........great lighting on those.

thanks finally experimenting with OCF ...and it's addicting!

yes. well done! particularly blending the ambient vs. flash light..

sweet fixie! Black on white is such a good combo.

Thank you!

Those shots are dare I say...magical

Hey guys! I got an 11-16 the other day and have been playing around with it a bit. I haven't had a good chance to play with it outside or with big scenery (which is probably the best place for this lens), but I'm having trouble really capturing things well. If I have it on 2.8, it usually is only focused on one point or a couple of points, and can't capture the whole picture sharply. I've toyed with single-point or auto-point selection, but I can't seem to get it right. I've also played with OneShot and Servo and stuff, but I think it has more to do with the single-point/auto-point thing. How do I capture a big subject, wide-open and have it all in focus?

stop it down at f/4.0 or higher if you want a deeper DOF

But so many of these pictures were taken at 2.8 and they're all in focus@!

A sample from another member (at 2.8 ) for example:

I think I read somewhere that Ultra Wide Angle lenses are more prone to focus problems due to "Curvature of Field". This is more pronounced at closer focus distances and with faster apertures like f/2.8 due to less depth of field.

An example would be a flat surface like a wall. It is impossible to have the entire wall in focus.

But at longer focus distances the extra depth of field of the wide angle makes up for it.

Is that not correct?

you don't really have to worry about DOF when you're shooting this wide!

rough calculations/memory stuff, so I may be off a little, but I'm sure I'm close:

If you're at 11mm/2.8, focused on something that's 6 feet away from you, your DOF starts around 3 feet from your sensor, to somewhere just shy of 30 feet from your sensor
Same scenario, but add 2 feet (8 feet sensor to subject), then everything from 4 feet out to infinity is your DOF

DOF on a wide lens can almost be forgotten about - it can be really difficult to blur out the background, even at 2.8!

I guess you learn something new everyday...thanks for clarifying:p

Homer, thanks for the input. BTW, that's a huge list of nice lenses you have

So in the example posted above, if the photographer was far enough away, it wouldn't matter where he was focusing, right? Because the whole object is within that depth of field/focus?
