Thanks for your help! So, will the two SLR lenses I have work for close-up detail portraits, say for my eye or something. I want to be able to show the detail of makeup techniques, without the images looking distorted. I don't think I'll be using the Pentax for portraits since it's film, and I need to have the ability to upload images to my computer to my computer quickly. In that case, would you recommend another lens for the Canon for close-up detail portraits?
