Originally posted by Eulogy Heres how to make it no different than using a 52mm - Buy a 72->67, 67->62, 62->58, 58->55 55->52. In the end, it will be like having a metal lens hood, that should accommodate lenses as wide as 18mm or so
Also - Your lens will be very recessed. Reducing potential for damage, even if the filter is smashed to bits.
Not so sure it will be "like having a metal lens hood" as there will be a piece of glass at each end of the set-up, thus still making it possible to have flare. Of course, if you left off the filter, but kept on the adapters, then yes. Just need to make sure they don't have any reflectivity of their own. Also, if there is impact, it will be directly transmitted to the lens, as the "hood" has no "give" to it.
I may, though, stand corrected if someone has had a good experience with this set up. Just be careful not to shoot in the sun, I guess.
