I have been pondering this question for a while and thought to throw it out there and get everyone's opinion. We all know that old 50/60s lenses often have poor coating which could affect image quality in certain light condition. I was wondering if adding an expensive modern multicoated UV filter in front of the lens would will improve lens with a lot of veiling flare? You think this would work? If not, why not? _________________ Follow me on 500px |

I think he was more referring to, if you could buy a filter that had modern multi coatings would it significantly help older lenses with no coating or only single coated? Could it add more saturated colours and contrast? It will likely impact flare as filters do so I think the focus on saturation and contrast should be foremost. _________________

Every glass-air surface cause reflections.
For normal incident it is about 4% on an uncoated glass, and less than 1% on a coated glass.
For oblique rays it is more normaly.
An uncoated front lens reflects more light back to the filter. So a filter will reflect more light back into the uncoated lens than on a good coated lens. So a filter cause more harm on an uncoated lens than on a coated one.
A very good filter has less reflections than a cheap coated filter - but both reflect more light than no filter.
If you use a filter as protection, you ned to be aware that you get more stray light or flare - not every time visible, but for example at night photography a filter could decay the work much. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

I find this all to be true from my own experience.
But forgetting flare for a second and how a uv filter can cause anomalies etc
Would a good multi coated filter potentially improve saturation and contrast on a non multi coated or single coated lens? _________________

Ok cool. Was just a thought.
I am not trying to make dog turds into jewelry however. I have good glass, I always just wondered if I put a multi coated filter on say one of my old Leica lenses which is very sharp just lacking contrast and saturation due to old coatings, would it improve contrast and saturation if I put a new multi coated filter on it. But you are all saying no, fair enough...but has anyone actually tried it? Done side by side comparisons between the lens alone and then again with a multi coated filter screwed on? _________________

Most UV filters cut UV where the lens + camera would very damp it too. So no improvement there.
But: There are definitly filter that can improve image quality in terms of sharpness. Take a small bandpass filter, and you get rid of color aberrations _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

A filter, multicoated or not, has no ability to remove the reflection of other optical elements of a lens. And if the filter is not of high quality, it will introduce its own reflections, further degrading the performance of the lens.
UV filters are one of the greatest deceptions in the history of photography, as ordinary photographic lenses do not transmit UV. The lens itself filters out the UV radiations. The UV filter is totally useless except for the mechanical function of protecting the front lens against accidental shocks. _________________ If raindrops were perfect lenses, the rainbow did not exist. |
