May i offer a little advice, its NOT about the gear, do not worry about the gear, although that is important, your much better off looking at images that you like and try to create the look you wanted, by playing with light, composition, and posing and yes some of the coolest images i ever created NON porn where done with .1 mm thick Aluminum foil with .25 mm hole punched in centre.
