On the Leica forum there is a lot of discussion about the strength of different brands of filters, B&W being the strongest, Leica the weakest and Heliopan in between. By the light reflected it does seem that the heliopan reflects more IR than the Leica filter and is therefore slightly stronger. Please see: http://gallery.leica-users.org/v/Howard+Cummer/UV+IR+Code+Pix/IR-Cut- FiltersW.jpg.html http://tinyurl.com/2je3u8 Whether this makes any difference in real world pictures is a matter of debate but the consensus is forming on the forum that for focal lengths 21mm and wider Leica filters are more compatible with the adjustments provided by the 1.012 firmware update when using coded lenses and for narrower view lenses it doesn't matter so much which IR cut filter is used. Just my 2 cents additional for today. Cheers Howard (in Hong Kong and now going out to take pictures.)
