I bought some extension tubes and am starting to practice macro photography. I've been using my 24-70 f/2.8 mostly at 70mm, and man, I am quickly realizing how razor thin depth of field can get. OK for certain shots, but what if I want the entire subject in focus?
I read some discussions in here about focus stacking and using focusing rails, and have a Question:
How is moving the lens 1mm (or whatever the increment is...maybe 0.5mm or less?) closer and closer and shifting the point of focus, any different than keeping the lens stationary on the tripod and manually adjusting the focus ring ever so slightly? Is manually adjusting a focus ring on the lens a blunt adjustment compared to the fine tuning a focus rail provides?
Thanks for your thoughts!
