I've waited 6 years to save up to purchase one of the two lenses I wanted for my camera before coming across this site. I was super nervous to purchase a lense sight unseen, but after combing through many reviews and reading over their rating system I decided to take a chance to see if I could save myself some money. I purchased an Excellent rated lens and was impressed beyond relief once it arrived. I received a practically brand new lens for a fraction of the price. KEH will now be my go-to camera equipment company for future purchases.
