This is a Vivitar 28mm F2 in excellent condition, with no glass or mechanical problems. I've shot with this lens on my Canon FTb-QL and it delivers astonishingly good results even wide open! The lens is fast and wide providing tremendous versatility for shooting in confined spaces under ambient light, or for outdoor work in low-light situations such as on city streets at night. The sale includes a really finely made original case and Canon lens caps. I've set what I think is a favorable price. Price: $50 plus shipping. I ship to most countries and take PayPal.
