wlaidlaw Posted May 18, 2011 Share #4 Posted May 18, 2011 Duncan Meeder / Foto Henny Hoogeveen have very kindly send me some more bigger pictures of the cut away Tri-Elmar which I post here, with their permission. I am continually surprised that Leica has not re-issued an updated version of this lens. A number of people have said to me that they would buy an M9 if they did. The only problem with the current one is that even the series 2 is fragile with a mount that requires delicate handling and often is subject to issues. For example my series 2 (one of the very last in a black silver box and coded from new), works perfectly on my M8 but on the M9, to get the viewing frame for 50mm to display correctly in the VF, you have to go from the 35mm side. If you go to 50mm from the 28mm side, the 50mm frame only displays faintly. Not worth going back to Solms to rectify. On a revised lens, I am guessing it would become optically a zoom and the 28mm length would be better than the series 1 or 2. At 28mm f4, the Tri-Elmar is just a touch on the soft side.

I just did a search for Tri-Elmar Cut Away to post those pics I had been sent and did not notice the section it was in. Maybe Customer Forum or Barnack's Bar.

wda Posted May 18, 2011 Share #7 Posted May 18, 2011 Advertisement (gone after registration) Wilson, I have no problem with viewfinder frames with my series 2 version lens, but it is a complex mechanism. Link to post Share on other sites More sharing options...
wlaidlaw Posted May 18, 2011 Share #8 Posted May 18, 2011 Wilson, I have no problem with viewfinder frames with my series 2 version lens, but it is a complex mechanism. As I said, mine is fine on the M8. Maybe I just need some Solms fairy dust sprinkling on it, as opposed to the fairy other substance that ends up on the sensors ;-}} Wilson Link to post Share on other sites More sharing options...
ho_co Posted May 18, 2011 Share #9 Posted May 18, 2011 It's the only lens I've seen that comes with instructions, viz what kind of oil to use to lubricate the sliding mount tab, and how often to do it. Wilson, maybe that's it: They discontinued the lens because its lubricant was fouling the digital sensors. Shoulda just moved the MATE repair guy to another desk.

Wilson, maybe that's it: They discontinued the lens because its lubricant was fouling the digital sensors. Shoulda just moved the MATE repair guy to another desk. Howard, I did a swap for mine of a virtually new chrome 50/1.4 ASPH for the MATE. The instructions were missing from the box. What sort of oil should I be using on the sliding mount tab and how often. Maybe that is the issue with my M9. I certainly have never oiled it since it came back from its last visit to Solms in Jan 2009. Wilson Link to post Share on other sites More sharing options...
ho_co Posted May 19, 2011 Share #11 Posted May 19, 2011 Wilson, sorry, I can't find the instructions at the moment. Leica Customer Service could doubtless inform you. I've never lubricated mine; I think the main thing is not to over-lubricate and to be sure the movement of the frame-setting tab is free. I've started a new thread to try to get an answer: http://www.l-camera-forum.com/leica-forum/customer-forum/182489-tri-elmar-28-35-50-help.html.

wlaidlaw Posted May 19, 2011 Share #13 Posted May 19, 2011 Hello Everybody, What about also putting a picture of the cutaway in the Forum wiki? Best Regards, Michael Michael, There is already a pic of a cut away on the Tri-Elmar section of the Wiki. It has a different serial number, so it must have been a regular activity to get a hacksaw out and slice your Tri-Elmar in half. Wilson Link to post Share on other sites More sharing options...

ho_co Posted May 20, 2011 Share #17 Posted May 20, 2011 Wilson-- Here's Carl Brettville's response from the other thread: Howard,On page 16 in my Tri-Elmar v1 booklet under "Tips for lens care": "In order to ensure smooth lens changes, the bayonet has been coated with a thin layer if grease in the factory. Normally, this lubricating film will remain on the lens for years, even if the lens is wiped from time to time. In the event that a grease solvent is used when cleaning, a fresh layer of grease should be applied. To do this, apply a small of vasseline to the bayonet with your finger and spread it with a clean cloth. Attention: Do not apply too much vaseline to the bayonet." Note the following from page 11: "When the lens has not been used for longer periods of time a definite resistance might be felt when rotating the focusing ring. This only occurs at the first turn however and does not signify a defect of the lens." I remember when first getting mine (old new stock) I thouht there was something wrong with it as the focusing was increadibly stiff. Reading the above passage calmed me down.

wlaidlaw Posted May 20, 2011 Share #18 Posted May 20, 2011 Wilson--Here's Carl Brettville's response from the other thread: Thanks for that info Howard. I already use silicone grease (RS-Components) on all my L-M lens mounts. It has a higher lubricity than Vaseline and does not age, turning to yellow wax, as the more volatile, lower molecular weight compounds evaporate. I was envisaging getting an oil can out and squirting it into the moveable tab area ;-}}. I am guessing that the VFF change is stiffer on my M9 than my M8, so does not work as well going from 28 to 50mm. If you give the frame change lever a little flick, the 50mm ghost frame changes into a proper one and the ghost remnants of the 28 frame disappear.

wlaidlaw Posted May 20, 2011 Share #20 Posted May 20, 2011 Howard, When I first got the Tri-Elmar, when you changed to 28mm on my M8, it did not display 28mm in the EXIF unless you held the focal length change ring hard against its stop, even though the frame was correctly selelcted. It had just come back from Solms for not changing the frame properly at all. I spoke to Solms and was asked to send both my M8 and T-E in and Leica arranged pick up (there was also a focus issue after the upgrade, so I was happy for the M8 to go back). I was told that it was very difficult to get a T-E working consistently well on two different cameras. They said they would set it up to change frames perfectly on one camera and get the correct EXIF's and when they put it on another body, it would not be quite right. I guess that is the issue on my M9. It is certainly not going off to get a perfectly liveable-with issue adjusted. Maybe that is one reason they have not re-issued the lens.
