I did this after making a mistake and got a mail back promptly acknowledging the correction to my order. The correct filters arrived by Fedex in about 10 business days!

Our conclusions are the same (I think). Wide lenes really do need to be coded. ( I do hate spending the money and only wish I'd had the 21 done early on, when it was cheaper). There is a slight colour cast from the IR filter at 35mm, but in practice I did not notice it till I tested. My 35 is not coded, but I think it too should be. I agree on "always use the filters", but until you code the wider lens, its going to create a nasty colour shift, so while I don't have coding, I think no filter is better than one: I will do some real world tests some time when my doctor allows me out of doors again. Lastly: damn I ordered the 49mm iR filter for the TE planning to use the b/w filter on the 21 (I had a 49-55 step up ring on the TE. It was working fine, so I should have left it and ordered the 55. Oh well "test and learn" Cheers and thanks --- len-1@comcast.net wrote: From: Leonard Taupier <len-1@comcast.net> To: Leica Users Group <lug@leica-users.org> Subject: Re: [Leica] I have come to this conclusion Date: Fri, 22 Aug 2008 08:14:47 -0400 Hello Alastair, First let me congratulate you on your winning the Leica-Dior contest and your new M8. That is quite an honor and attests to your excellent photographic skills and photos. Now on to your conclusions, #2 in particular. First, if you have lenses 28mm and wider and you want to shoot color, get them coded and get the filters. Without coding and with or without filters the purple cast or the cyan corners are difficult to get rid of. If you don't care about accurate colors then don't worry about it. Always use filters. Your photos will be sharper, especially with the non-APO lenses. IR and visible light focuses at a different point and with the high IR sensitivity of the M8 it might make a difference depending on the light source. The differences may be subtle but we don't spend $3500 for a lens and then get soft photos. I would always use a filter on the 35mm lens, coded or not. I have a coded 35mm Summicron ASPH and the 35mm Summilux ASPH not coded. Both have filters and I have no problem with color casts with either. Use Leica brand filters on the ultra wides, primarily the WATE and 21mm Elmarit Asph. The difference in the color correction with different brand filters is noticeable in the corners. I have no problem with Heliopan, B+W or Tiffen on 35mm and longer lenses.
