Digital BW, The Print

I recently acquired a Leica lens that came with a UV/IR filter. I understand that this filter is for use with a digital camera. Is there any problem with using it as a UV filter when I shoot black and white film? Thanks. Paula

A UV filter does nothing more then provide a cover for the front element of the lens. Its only use is to keep the front element clean. A low quality UV filter can actually degrade the sharpness of the lens. Personally I never use a UV filter, a waste of money. Be careful with your lenses and  a UV filter is un necessary.

Filters are usually virtually colourless if they are to block out UV to be UV filters Paula, but a dark red, almost black colour to block out all but IR to be an IR filter. All UV filters are interchangeable, but with IR, digital sensors are sensitive to a different wavelength of IR. Again, it would do no harm to either camera, but if you are trying to do IR film photography, the wavelength, the "colour" if you like, of the filter and the special IR film are best matched for the best results.

I used to think that too, until I went base over apex taking photographs in an engineering works one day - my camera survived, but with a large dirty, greasy, hand print on the front element where I had tried to protect it. Whilst we all take the upmost care of our all out photo gear, there will always be an incident sooner or later when circumstances are beyond our control! For what it costs, in this case nothing as it is already there, why risk it if the filter is of decent quality, rather than the cheap and nasty you are assuming? Strangely enough, because film cameras don't have the same problems with reflections off the sensors as digital cameras do, any recognised brand of filter, anything that is not the bottom of a bottle, is more than adequate - grinding flat glass is not a problem! I have just bought one of the last Sony A700's with the 16-105 lens here in the UK, discounted as a discontinued clearance item, so there is no way I am going to risk having to buy another lens at what would be the full stand alone item price for the sake of a £15 filter!

if your lens is wider than 35mm using the uv/ir filter with film camera will
ruin your pictures as all of them will have cyan fringing on the corners.
these filters are for use with only the m8 camera

If it is a Leica UV/IR filter its purpose is to replace the AA filter 
that they deliberately left off of the sensor of the M8 to give finer 
detail.  You do not need it and should not use it with film.
