filters for summicron 1:2/90

Hello, I have a summicron M 1:2/90 for my M8. it has not the 6 bit code but an UV IR CUT filter. I just noticed, that it has also a UVa filter. I am not sure if it is good to have both filters on. I know that the UV IR CUT is necessary but I think it is not correct to have both. In fct, the pictures with this lense is always strange in colour, somehow with low contrast. On anthother side, is it correct that I will not need the UV IR cut with the M9 (whenever I receive that camera). should I then put the UVa filter but not the UV IR? I would be greatful for a help. thank you,

BOTH filters on is surely to be avoided; with M8, I consider the UVIR as almost mandatory, though certainly there can be specific photo tasks in which one doesn't need it (I made some ancient architectural subiect pics with 21 asph unflitered - lens detection on - very good) , but anytime you have fabrics or nature (foliage, meadows..) in the frame, the UVIR adds definitely to the color balancing. With a 90mm lens, the coding is de facto un-necessary for color correction at the edges... so you can simply put the UVIR on and set lens recognition off... you simply lack the lens info in the EXIF file, and that's all - colors are "right".

 

I haven't yet a M9... ... UVIR ought to be superflous... and I suppose that a standard UV filter could be useful in the situations in which it can be in film (high altitudes, stron sunlight etc...)

Thank you very much for the information which is very useful. sorry for not saying something earlier, I had problems with my access to internet for several days. this is regrettably common. thank you for your help.

Look, Luigi, the old pre-ASPH 90mm Summicron does auto-code itself as a 90mm 1:2.8, courtesy of a screw head in the coding area. At least mine did. So you can keep the auto coding on.

 

You can in fact keep auto coding on with all lenses of 50mm and longer. No menu-diving is called for. I did not mess with it. None of the (unspecified) horrors that Leica intimate in the manual did materialise. Now I am driving a M9, and my M8 sits on a shelf in the window of my Leica dealer.

I'll try, Lars... but I'm not lucky about "screw-activated-recognition"... : http://www.l-camera-forum.com/leica-forum/leica-m8-forum/106777-m8-recognizes-uncoded-tele-elmarit.html#post1130750

The camera thinks it is a four element Tele-Elmarit. I have one and that one works too.

Hey ! I tried tonight my Cron 90... It IS recognized ! Clearly credit goes to the cross-cut screw-heads... "read" better than the single cut heads of Tele Elmarit... and probably also for it comes from Your Country, Lars...
