I have noticed most people spend a lot more money on vintage or collectable muti coated lens is this wise? I was thinking how good of a long term investment can a muticoated lens be? I mean after a number of years most lenes will be aflected with haze or fungus destroying coating's which a newer lens would base the design on the number of air spaces and delicate coating's making a modern lens worthless after time has its way with it. I know a uncoated lens can be etched by fugus but I hardly ever see this. So do you think if you used a hood and filter and did not shoot towards the sun the results would be so poor. I have a leica summicron screwmount the coating has worn off no where to recoat that I know of. Maybe it would be better to collect cheap uncoated lenes what do you think?
