Message: Greatest lens ever made for film camera! I don't care what anybody says about this lens it is finest I ever used on my F1N. I took many shots wide open and got brutal detailed images. There's one in EBay auction right now and I am very tempted to buy this lens again after letting one go 3years ago. I regret selling mine to get Nikon F3 the worst mistake I ever made. This lens with F1N potential is endless. I still have 50mm 1.2L lens but something about 55mm 1.2 Aspherical lens able to achieve corner to corner sharpness like no other normal lens. Pity it won't work with new Canon 21mp Mark III I wonder how images would look in digital world. Long live Greatest Canon FD lens ever made.
