What is the deepest, most beautifully iridescent lens coating you ever saw?
I think the deepest purple color I ever saw was some old Ayashi Pentax lens that I thought was a beater until I looked at it the right angle. I was looking at some OM lens and it was pretty too.
The widest is on my Fujinon 300 f5.6.
The most non existent? My magnifying glass lens I like to play with...
The most unusual... I don't even know where to begin...
boy, the best I've seen would have to be on my friends leica (not sure what lens it was), but it was a greenish yellow IIRC, and it was beautiful!!!!
saw it at his 4th of July party this year, at the end of the day, when the light was soft, and a spot of sunshine poked through the trees, and lit up the element.
What a strange subject to bring up, nevertheless...
The green-blue hue of my Canon 70-200 f4L or the purple-bluish hue of my 24mm f3.5L TS-E.
I don't stare at the lens too long: I can see somebody in it and I don't like what I see...
A couple of weeks ago I stared down long and hard at a Carl Zeiss Planar T* 80mm and didn't see any visible coating! I did see dust inside the lens though...
Rodenstock Grandagon f6.8 90mm from the late 70's early 80's - the coating is so good it's almost impossible to see, or get a reflection off a glass surface.
But some other lenses Schneider, Rodenstock, Pentax aren't far behind, particularly my early SMC Takumars
Zeiss 80/2.8 biometar. Deep purple, almost black, no matter what angle you look at it. Almost no light reflected off it. Arsat MC 30mm 3.5 fisheye is a close second.
I have two OM Zuiko 50mm/f1.4s. the "black nose" one has a very nice blue-ish coating but the "silver nose" one has a completely different looking "gold" coloured coating. Both lenses perform very well but the "silver nose" seems slightly less critically sharp and a bit less contrasty which comes in useful when shooting in sunlight - hence the reason I've kept both.
Otherwise, I have a Nikkor AF-D 85mm/f1.8 and AF-D 50mm/f1.4 whic have beautiful purple and blue coloured coatings.
