I hope I'm in the right part of the forum.
I know there are some sites that give you mathematical numbers about depth of field when you punch in different numbers, but I don't really understand what I'm seeing.
I'm interested in buying an extender because I do need the extra reach. I'd use it only in good day light, so my only concern is the DOF.
Does a 400mm f4 produce about the same, more or less depth of field compared to 300mm f2.8? Is there anyone that maybe has a 300 2.8 and a 1.4x extender to show real life examples?
