Hey James,

Would love to know where I can learn that math...calculating dof based on aperture and lens would be a great thing to know... Does your calculation take into account the sensor size? My understanding is that the same lens used at the same aperture and focal length on a t2i and 5d will yield a shallower dof on the 5d due to the 5ds enormous sensor. Is this correct?

Yes sensor size is part of the calculation. As you say, the bigger the sensor the shallower the DOF, other things being equal.

I don't think the maths is that hard to learn, but why bother when you can get a computer to do the work? Here are two useful online calculators that will enable you to pose as a ninja photo nerd:

What do you think about getting "the three Canon low-light primes"?

I mean...

28mm 1.8
50mm 1.4
85mm 1.8

... and maybe cheat in a Tokina 11-16 for ulta wide shots.

Do you think that set would work?
