Prime objective
Hi,
I am considering getting a "prime" objective to use indoors, in low light conditions. Also it would be great for the added depth of field.
However I have a question. I have a Canon 450d DSLR which means its not full frame. Essentially I have to multiply the focus length by 1.6X. So I was wondering should I get a prime objective that is 50mm (meaning effectively 80mm) or a 30mm (which would give me 48mm effective).
