Ok i have my first possible opportunity, but im not sure what size lens would be good for this? I would be doing close up work of tattoos, she has several and is making a portfolio of them. As you may know that I am new to photography and as of now only have a 30-200mm lens so i need to know what would work best for this so I can get one, which I am going to need anyways. And being newbie at this when she asked for a price all I asked for was to be able to use her pics in my portfolio also, was that the best way to do it? I thought it would be that way it helps us both, she gets her pics and I get the experience. Thanks for the help.
