Ivar B Posted October 3, 2007 Share #1 Posted October 3, 2007 Advertisement (gone after registration) I had my shipment with Leica UV/IR filters yesterday, or I had one filter (43mm) while the other i ordered (55mm) appears to be out of stock. On the export documents, country of manufacture of the filters listed as Japan. Any idea who actually makes them? Link to post Share on other sites More sharing options...

The first filters come form B+W, but doesnt work, so Leica never shipped them and ordered filters from Hoya Link to post Share on other sites More sharing options...

pelikan1931 Posted October 3, 2007 Share #4 Posted October 3, 2007 i can see some cyan corners using E46 B+W filter on my coded 28 summicron, none with my Leica E46. I guess the B+W is designed for totally IR filter free sensor, whereas the M8 has just a very thin IR filter in front of sensor. Link to post Share on other sites More sharing options...
sparkie Posted October 3, 2007 Share #5 Posted October 3, 2007 Hang on, is this true? I bought quite a few B+W IR CUT filters early on as Leica IR filters were taking too long to arrive. I'm pissed Link to post Share on other sites More sharing options...
stunsworth Posted October 3, 2007 Share #6 Posted October 3, 2007 Sparkie, I'm using B+W filters on 24/28/35/50 and 90mm lenses and haven't personally noticed an issue. Link to post Share on other sites More sharing options...
larry Posted October 3, 2007 Share #7 Posted October 3, 2007 Advertisement (gone after registration) The B+W filters work just fine. I'm not sure where this rumor started. Larry Link to post Share on other sites More sharing options...
sparkie Posted October 3, 2007 Share #8 Posted October 3, 2007 I have read on one of the threads that only the leica IR filter will not produce cyan corners on the WATE perhaps the rumor was a spin off of this Link to post Share on other sites More sharing options...
robsteve Posted October 3, 2007 Share #9 Posted October 3, 2007 The Leica brand are really only needed on the 21mm and wider lenses. The B+W creates too much of a cyan cast in the corners of the super wide angles. I am like steve and use B+W filters on all my lenses, except the WATE, which has the Leica filter.

@bumac Posted October 3, 2007 Share #10 Posted October 3, 2007 I use B&W on my 25 from Zeiss, the 35 (Serie VII) and on my 50. No problem at all. Link to post Share on other sites More sharing options...
AGeoJO Posted October 3, 2007 Share #11 Posted October 3, 2007 I am using Leica filters for my 21mm and 28mm. The other 4 lenses have either a B+W or even a 55mm Heliopan. I did get cyan shifts on my 21mm in the far corners using the Heliopan before I finally got my 55mm from Leica. The Heliopan is now on my 90mm Summicron with no ill-effect, thank you. The IR filtering effect of the Heliopan and to a certain degree on the B+W appears to be stronger than that of the Leica ones. That much actually that it creates the cyan shifts in wide angle lenses. See Sean's review on the various IR filters. Link to post Share on other sites More sharing options...
gerasdoc Posted October 3, 2007 Share #12 Posted October 3, 2007 It's not a rumor. Leica recommeds using it's own IR cut filter on lens wider than 28mm. Link to post Share on other sites More sharing options...
mas Posted October 3, 2007 Share #13 Posted October 3, 2007 I'm having great luck with B&W. Leica, however, can't seem to get anything shipped and when they do, they are defective. My silver 43 won't screw on more than half a turn on any lenses. On a $5500 camera to get service this bad is criminal. Michael Link to post Share on other sites More sharing options...
pelikan1931 Posted October 3, 2007 Share #14 Posted October 3, 2007 for outdoor shots, the B+W is fine, but cyan corners become noticeable for indoor shots, on my coded 28 cron. the purple/red hue coating on the B+W seems to be thicker/darker.

sean_reid Posted October 4, 2007 Share #15 Posted October 4, 2007 Interesting. Are you in effect saying that filters from B + W do not work? Some results from extensive testing... B+W filters work very well but the Leica firmware is tweaked for Leica filters. The difference is noticeable (in some lighting conditions) with 21 and wider (sometimes 24 and wider) lenses and negligible thereafter. This has nothing to do with the quality of the filters. This has nothing to do with the quality of the filters. This is simply a result of how the corrections are written in the M8 firmware. With 28 and longer lenses, the B+W filters are fine and the Heliopans do fairly well as well. Cheers, Sean Link to post Share on other sites More sharing options...
