Leica LTM Question of MC filter on Flare.

[raytoei@gmail.com]

Hi,

I have a flare-prone 50mm collapsible Summicron.

Does a Multi-coated yellow filter improve the flare situation ?

I was reading up on a Rodenstock literature and it mentioned that the filters are Multi-coated and reduces flare. Does that mean that the resultant IQ is less flare prone ?

thanks

ps. any good yellow filter (filter factor <=2) to recommend ?

No, it will not impact the lens optics. Your lens will have flare just as it always has.

However, a MC filter will perform better than a SC filter. So if you use filters, there is an advantage to getting MC ones. This includes reducing reflections from the lens into the filter.

I recommend Hoya or B+W as good filter manufacturers. I would avoid Heliopan. I have never been impressed with Tiffen.

The only way in which a filter can affect lens flare is by adding to it.

Here is a good discussion of filter flare, and at the bottom of the page a couple of other related pages:

Which verify payasam's point.

That was my immediate reaction. A series of thought-experiments aimed at proving the opposite have all collapsed dismally.

Thanks for all the reply.

Flare is the result of reflections at glass-to air-space transitions in a lens system.

Using a coated / multicoated filter will minimize any additional flare potential caused by the filter itself, but it will not reduce the tendency of your lens itself to flare.

The only flare reductions would be achieved by using a lens hood, and /or having your lens sent- out for coating.

Good luck !
