Originally posted by ecitraro Toward those goals, I will probably be looking at adding some used lenses, specifically something that will shoot 36" x 48" canvases (the largest I have to date). I'll also need an improved lighting system as I have a number of very heavy impasto works, as well as shiny pieces, drawings, and watercolors, but for now, I will just use northern shade/daylight.
Welcome! for the past year I´ve been working with art reproduction. You´l need a lens with even resolution (form center to corners). the longer (between 35mm and 100mm) you can afford (due to subject distance and reflections), the better. a 50mm Macro lens is a good start. Even better a 70mm or 100mm Macro lens (Pentax, Sigma, Tamron). This is also a great general purpose lens that should be in every photographer´s bag. And regarding lighting, continuous lighting is far easier to set up (to ensure even lighting).
I´ve been working with the K-5IIs and it´s great. So the K-3 should be even better. Good luck!
