Hi Howard,

This is quite surprising for me, if you have unwanted reflections with an IR
filter I see no reason to have the same problem with an UV or any other
filter. Did you asked Leica?, this can ruin a good picture, this one is very
good but ruined by this effect.

Saludos cordiales
Luis

Asunto: [Leica] Lens reflections from IR cut filter - Mui Wo Ferry Pier

Hello Luggers,
Well my replacement M8 is in Hong Kong with Fedex, according to the
tracking, but didn't get delivered on Saturday. Monday is a holiday (China's
National Day) so I expect the camera will arrive on my doorstep on Tuesday.
In the meantime, Schmidt has given me a loaner
M8 and so I have been out on the streets again. Here is a picture of the Mui
Wo ferry Pier, where the ferries come in from Hong Kong Island, taken with
my newly coded 50mm Summilux Asph, wearing an IR cut filter. I know that
conventional wisdom is that lenses longer than 35mm don't need to be coded,
nor are IR cut filters really required, but I have decided to code and
filter equip all my lenses - so that I don't have to think about switching
lens detection on and off for Coding and IR filters. Besides I like to know
the focal length in the EXIF data. One problem, however, with using IR Cut
filters unnecessarily is unwanted reflections. Please see the attached photo
of the Mui Wo ferry pier.
