I have been having problems with picture focus. I am using a f4.5 300mm lens on my D300. Here is what I would like to see. How do I compare the DoF of a 200mm 2.8 Lens vs my 300mm 4.5 Lens? I think my DoF is too shallow because I'm not compensating for the extra focal length compared to the 200mm lens.
So, in the end, how do I compare f-stop vs focal length when figuring DoF? I hope this makes sense...
Thanks!
