    Help-Lens coder kit does not work

    I purchased the d-coder kit and have tried a lot to get the camera to recognize
    the lens. I have the recognize lens IR on . Using a Sharpie pen to mark the lines or dots on the lens using the decoder. I have it with the right side up.
    I tried 3 different lens and not one will work. 50mm, 35mm 90mm
    Have anyone else have this problem.
    Thank

    Have you checked the coder template against the camera mount?. If the detent slot and code reader diodes don't line up it can't work. this was the situation with one template I downloaded.

    try the coder ring on a lens that's already coded and see if you need to offset it a bit.

    Re: Help-Lens coder kit does not work

    I had the slight offset problem with the one I got originally (blue). I found I had to offset it slightly for an accurate registration. You can only really check with a coded lens.

    Something else to watch out for is that the mounts bring up the correct framelines because they are used alongside the code. This was a problem for some of the ZM lines (21 certainly).

    Any advice where to buy the best (easiest? most reliable?) coder?

    I have the Bo Coder, for $5, it is excellent! I highly recommend it:

    Here is the original post on the coder:

    For the Bo Coder too. I liked mine so much, I saved up and bought a second. No registration issues whatsoever.

    Thanks again Bo!

    It worked for me if I was very careful. I know the maker, Tim Isaac, and he'd happily replace it for you if it's not working for you. You can reach him at www.matchtechnical.com.

    A note from Bo:

    "M9 UPDATE: Just got my M9, clearly something have changed, my coded lenses which works just fine with the M8 mostly did not work with the M9... until I socked on a bunch more ink. they must have changed the sensor to require more contrast, as a single layer of sharpie don't seem to do the trick anymore. this will be a easy fix on the new grooved lenses, I'm heading out in town for black model airplane enamel.. on my 15mm I have a coding strip and this worked, but the same strip on the CV 35 1.4 did not work, probably because it was a bit more worn, I updated it with a fresh one and now that lens also works.

    Conclusion... soak on more ink, paint or whatever you are using for black. The M9 have a more picky sensor, I'm almost wondering if they did this new calibration to bug people doing sharpie codes."

    Where can you get the codes with which to use the coder?

    Jack, send me an email and I'll send the codes out to you; I have them in a word document file.

    Re: Help-Lens coder kit does not work

    Here are the codes I found. Waiting for the Bo coded. My Xacto skills I guess weren't very good. IF you have a chance, check your coded lens against it and confirm.

    The Match Tech M-Coder kit from Tim Isaac works very nicely. The template snaps securely into place, the look-up wheel is comprehensive and easy to use, and the machinist pen works better than Sharpie. I've had no problem coding some of my older lenses with it and being recognized by the M9.

    Than's the coder I am using, but will try the Machinist pen. Have been using a Sharpie.

    I can confirm what Bo wrote; the M9 is much more finicky than the M8 with manual coding. It's been a bear to get them to work as I would like on the M9 when they worked fine on the M8.

    Update. Just coded my Zeiss 28mm for the m8 with Bo's coder and the lens code below. I have to say, I did a poor job with the sharpie. Slapped the lens on just to see how bad, and it worked great. The info on the photo shows 28mm.

    90 Elmarit coded with Match coder; the process took perhaps a minute and my M9 recognized the lens. This is a slick system as the plastic template snaps firmly into place on the lens mount making accurate placement of the marks a breeze.

    Tom, thanks for the update. What type of marker you prefer?

    Re: Help-Lens coder kit does not work

    I found the only problem with the D-Coder kit is that the fine side of the pen tends to dry up quite quickly. It often takes two or three goes to get the coding to work. I think the critical factor is the width of the lines you draw. I generally mark the position with the coder and an ultra fine black marker (even finer that the supplied pen) and then widen them out slightly, after having removed the coder. I still find that a Pentel Sharpie gives the most consistent results. The only lens I have failed on (and then only on my M9 - it works fine on my M8 ??????) is my older model Zeiss ZM 50/2 Planar. This is the model before they moved the mount retaining screw countersink. I have tried filling the recess with various materials but still no joy on the M9. Of course I can code manually, which is why I am not too worried.

    Not to burst your bubble, Tom, but my M8 read my 90 pre-ASPH as a 90 pre-ASPH with no coding. It seems the screw is in such a place that the M8 read it as a code.
    I have used both the Tim Issac and the $5 coders. I use the $5 now. Both work great. If you are looking for a more permanent solution, you might check with Don Goldberg. He sent one of my mounts out for coding, while my lens was in for adjustment. He may still be offering that service.

    Burst away, Cindy. The lens I coded was a 90 Elmarit, not the Cron.

    I have also just coded a Zeiss Biogon 28/2.8 successfully. I thought this might not work because of the screw located exactly where one of the black dots goes, but it did succeed. I coded it as the 28/2.8 pre-ASPH.

    I was just kidding.
    The M8 did often read screws as black dots...that is why it read my 90 cron correctly without any coding. That might not be true if the M9 is more demanding.

    Re: Help-Lens coder kit does not work

    Cindy, that is interesting about screws being read as a black dot. I had assumed that my effort to blacken the screw, which was only partially successful, had done the trick. That would suggest that there are some lenses that cannot be hand coded a screw is located where a white dot must be. Maybe whiteout would work? I had intended that as a joke, but then it might work.

    Re: Help-Lens coder kit does not work

    Whiteout might flake off. We had good success with black and white nail polish when there were detents reamed out. I haven't heard of any lenses that were not able to be coded. I wouldn't worry about any lens over 50mm that was not coded anyway. You would just lose the ability to check the exif, but vignette correction is not usually needed over 50mm (in my experience).

    Re: Help-Lens coder kit does not work

    I was an early tester for the Bo $5 coder. It works very straightforward. You can go to your favorite office supply store and pick up a few sharpies of different tip thickness that work for you.

    However, after doing my own tests, and studying Sean Reid's, I haven't found coding needed for these lenses:

    CV 15/4.5, CV 21/4, M-Hexanon 28/2.8, Canon 28/2.8 ('50s), CV 40/1.4, Leica E43 50/1.4, Leica E46 50/1.4, Leica 75/1.4, Noctilux F1 E60, Summicron 35/2, or a dozen other Leica and non Leica lenses.

    IR/UV filters on the other hand are good to keep around for specific situations.

    Re: Help-Lens coder kit does not work

    The type of ink used in the pen is important. Many pigments used in the inks look dark or black to the eye but are transparent to infrared and will not work. The M8 and M9 use pairs of infrared transmitter/receiver diodes to read each code bit. If you can't make a coder work (although it should work with pens supplied) it's worth trying different makes of pens.

    Bob.
