The folks at Lens Rentals have a lot of filters lying around. One day, an employee named Kenny drew the sort straw and had to clean them all, stacking them as he went. And then he wondered, what if I shoot through these?
The results are not startling, but they sure are interesting. A shot through 50 filters looks like somebody smeared Vaseline on the lens. Things get even more interesting when you compare the best and worst filters (apparently not all Lens Rentals customers return the same good filters they receive).
Guess which is which? Photos: Lens Rentals
A photograph taken through five top-of-the-line UV filters shows surprisingly little degradation, despite ten air-to-glass interfaces. A picture through the cheap filters, though, isn't much different to the one shot through 50. The results are blurred and lacking in contrast.
As Lens Rentals' Roger Cicala writes in his post, this is a situation unlikely to ever occur in real life, but it sure shows the difference in quality between the cheapest and the best. The takeaway? If you insist on putting a UV filter on your $1,000 lens, then don't opt for the $20 model.
