sksaito Posted October 25, 2011 Share #1 Posted October 25, 2011 Advertisement (gone after registration) I'm not too good with filter knowledge. What is a Leica E39 type F filter specifically for? Will it fit Summicron 50mm DR lens? Link to post Share on other sites More sharing options...
Advertisement Posted October 25, 2011 Posted October 25, 2011 Hi sksaito, Take a look here E39 Type F filter. I'm sure you'll find what you were looking for!
luigi bertolotti Posted October 25, 2011 Share #2 Posted October 25, 2011 If I remember correctly "F type" filter is a bluish filter to use daylight films with tungsten lighting or flashbulbs (=Wratten 80 C); E 39 refers to the diameter and mount (screw) and is a standard used on many Leica lenses - all Summicrons 50 (new and old - DR included) do accept this kind of mount.

giordano Posted October 25, 2011 Share #3 Posted October 25, 2011 I believe this is the filter for using Type F color film in daylight. If so, it's a fairly pale amber colour and of historical interest only: Type F film was colour-balanced for clear magnesium flashbulbs and hasn't been made for decades. Assuming no damage, it'll fit any 50mm Summicron and many other lenses. Link to post Share on other sites More sharing options...
giordano Posted October 25, 2011 Share #4 Posted October 25, 2011 Luigi and I can't both be right:). Please tell us which colour your filter is! Link to post Share on other sites More sharing options...
luigi bertolotti Posted October 25, 2011 Share #5 Posted October 25, 2011 ]Luigi and I can't both be right[/b]. Please tell us which colour your filter is! Exactly the inverse in our interpretation of "F" ... let's bet 1c, hoping that sksaito tell us the color... Link to post Share on other sites More sharing options...
luigi bertolotti Posted October 25, 2011 Share #6 Posted October 25, 2011 Just read on Laney : "F type : "F" engraved on ring : conversion filter for Kodachrome or Ektachrome type F in natural light" : E39 type listed by Leitz N.Y. as FKDSMI (1959) A strange code...

sksaito Posted October 25, 2011 Author Share #7 Posted October 25, 2011 Advertisement (gone after registration) Sorry guys. I don't have the filter. Someone offered to sell it so I should ask. Thank you Link to post Share on other sites More sharing options...
doubice Posted October 26, 2011 Share #8 Posted October 26, 2011 Just read on Laney : "F type : "F" engraved on ring : conversion filter for Kodachrome or Ektachrome type F in natural light" : E39 type listed by Leitz N.Y. as FKDSMI (1959) A strange code... Strange code indeed - and the reason is that colour correction filters (and this includes Skylight filters) were never made by Leitz in Wetzlar. All colour conversion filters, including the above noted 'F' type, were mounted into Wetzlar-supplied filter mounts by Leica USA. Many of those filters will actually have 'New York' or "N.Y."engraved on the outside of the rim. Leitz New York used different coding system from Leitz Wetzlar. During my film days, I preferred to use B+W or Heliopan colour correction filters, with their much more understandable R and B numbered designations. For the original poster - the E-39 designation stands for a 39mm filter thread (E for screw-in or 'Einschraub' in German). Many Leica lenses from the 50's, 60's and 70's used E39 filters and the 50mm Summicron is of course one of them. However, this filter will be more or less useless today, because the 3200K and 3400K balanced films are just about extinct. The type 'F' filter was an orange filter that corrected the colour balance of films balanced for artificial (tunsten) light to be used in daylight.

The type 'F' filter was an orange filter that corrected the colour balance of films balanced for artificial (tunsten) light to be used in daylight. The film types were: Type B: balanced for 3200K pro tungsten lights - now rare Type A: balanced for 3400K amateur tungsten lights - now extinct Type F: balanced for 3800k white magnesium flashbulbs - long extinct Type D: balanced for c. 5500k daylight (and fake daylight such as blue flashbulbs or strobe).

gyoung Posted October 26, 2011 Share #10 Posted October 26, 2011 I have a couple of empty E Leitz NY E39 filter mounts, usually they have gelatin 80B (artificial A or B film to daylight) and 85B (daylight to A or B film) Wratten correction filters in them. No high speed artificial light film now unfortunately, only slow stuff (and I think that may have gone now) which is good for copying but no good for available light interiors. I have I think a long out of date roll of F type Ektachrome somewhere, kept as a souvenir! Gerry Link to post Share on other sites More sharing options...
