AGeoJO Posted January 22, 2010 Share #1 Posted January 22, 2010 Advertisement (gone after registration) I succumbed to the temptation.... Well, it didn't take much arm twisting , and I ended up with a 135mm APO-Telyt. However, this new lens is not 6-bit coded. I tried to get some info here as well as out there and I was not able to find any pattern on the coding of this particular lens. Could any of the owners of this lens that has been coded help me out, please. I do need the 6-bit code pattern of this lens. I realize that it would not do much, if any, for the correction but it is more for the EXIF data. In addition, what will be my best and fast bet of getting the 6-bit code put in? I found out about the Dymo method - is that still pretty much the best do-it-yourself method? Leica will take 2+ months to do this . Any help is appreciated, Joshua Link to post Share on other sites More sharing options...
Advertisement Posted January 22, 2010 Posted January 22, 2010 Hi AGeoJO, Take a look here 6-bit code for 135mm APO-Telyt. I'm sure you'll find what you were looking for!
Hacker Posted January 22, 2010 Share #2 Posted January 22, 2010 Same here, wonder whether the newer lenses will have the 6-bit code. Link to post Share on other sites More sharing options...
UliWer Posted January 22, 2010 Share #3 Posted January 22, 2010 The Apo-Telyt has no own coding. As the M8 had no frames for 135mm and they thought the lens not appropiate with the crop factor of 1,3x for the M-viewfinder and for there is no optical reason to code it, there is no coding. It's only introduced in the manual lens menue of the M9. If you have the M8, just wait a few days. There are rumours that the next firmware will allow manual lens selection for the M8. Just rumours ... we'll see. Link to post Share on other sites More sharing options...
AGeoJO Posted January 23, 2010 Author Share #4 Posted January 23, 2010 Aah, thank you, Uli. When I had my M8, although I considered getting that lens but it didn't go beyond mere consideration. The M9 changes things. So, I just have to set the lens manually on my M9. OK then, I will have to do that but I just have to remember to switch it back to "auto-detection" afterwards. I forget to that too often on my D700 using MF AI-S lenses. Again, no harm in the image quality whatsoever but the EXIF data is just off. However, like Hacker mentioned though, none of the newer copies of this lens is 6-bit coded then? Link to post Share on other sites More sharing options...
jaapv Posted January 23, 2010 Share #5 Posted January 23, 2010 Hve you considered just sending a mail to Leica to ask? Link to post Share on other sites More sharing options...
AGeoJO Posted January 23, 2010 Author Share #6 Posted January 23, 2010 It is actually more fun posting it here rather than asking Leica that question. Not that I am not interested in finding out the real answer but I would like to hear other people's opinion, too. Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted January 23, 2010 Share #7 Posted January 23, 2010 Advertisement (gone after registration) He He. would be kind of fun if they replied with a code... Say, have anyone tried a 135mm with goggles on the M9.? Link to post Share on other sites More sharing options...
brill64 Posted January 23, 2010 Share #8 Posted January 23, 2010 the 135mm APO-Telyt does not really need coding! Link to post Share on other sites More sharing options...
Bo_Lorentzen Posted January 23, 2010 Share #9 Posted January 23, 2010 I realize it don't need coding. for me I would like to code it just to capture the lens data into Lightroom. . Link to post Share on other sites More sharing options...
chris_tribble Posted January 23, 2010 Share #10 Posted January 23, 2010 Hi - I've had the same issue (and find it useful to be able to use exif file data when searching for images sometimes). I wrote to Leica and they inform me that they have no plans to issue a code number as they don't recommend the lens for digital RF as they don't feel focusing can be assured. This annoys me, but as you can select from the menu on the M9 it's not been too big a hassle. Also, I understand that a future firmware will check if you switch to using a coded lens - this I would like as I've had some interesting moments switching from 135 to 21 and forgetting to re-set coding from the 135... LOVELY lens on the M9 IMHO... good decision! Link to post Share on other sites More sharing options...
UliWer Posted January 23, 2010 Share #11 Posted January 23, 2010 I think you might code it as a 2.8/135-Elmarit, if one really wants the Exif-data. You find the code here in the last entry of the list: Leica M Lens Codes . Though I am not completely sure if this code doesn't show 90mm in the Exif, as the Elmarit triggers the 90mm frames. Funny - since the coding was introduced, so many people asked for a camera menue to select the lenses from. Now when this is introduced for the M9 and possibly will be introduced for the M8 as well, there is again demand for physical coding... Link to post Share on other sites More sharing options...
H. James Wolf Posted January 23, 2010 Share #12 Posted January 23, 2010 The 135 2.8 with goggles works just fine on the M8. Link to post Share on other sites More sharing options...
AGeoJO Posted January 23, 2010 Author Share #13 Posted January 23, 2010 Thank you very much for your input, everyone. Uli, thank you for the link of codes that Carsten put together. Chris, good to know that Leica may incorporate a reminder if you switch between coded/non-coded lenses in the future firmware. Actually, if they just could set it up that way that it would revert back to the manual setting of the last used non-coded lens would be great. For examples, if set on auto detect and a non-coded lens is mounted, then the last setting of the manually entered lens data will be used. I am not even sure whether it works this way right now and all my other lenses are coded. My new lens is still on its way and I cannot check this out on my M9.

I had the same problem more than once, I really hope the next firmware will sort this out. Btw, I'm glad I'm not the only one! Link to post Share on other sites More sharing options...

I tried this - but as the 135 Apo brings up the 135 framelines (not the 90) it doesn't work on the M9. I had a kludge for the M8 where I used an adapted backplate that brought up the 90 framelines and I then got the 2.8 135-Elmarit coding to work. With the M9 all you can do is manually select.

Bo_Lorentzen Posted January 24, 2010 Share #17 Posted January 24, 2010 Ario, The reason for not putting 24mm frame lines on the M9 is quite simple. you would not be able to see the framelines. On the M8 the 24mm with crop factor framed what is practically speaking 31mm focal-lenght. on the M9 there is a 28mm frame line, this is actually a little wider than the 24mm on the M8. The shift in framelines is because the M9 is fullframe and as such the same lens covers a different area. . Link to post Share on other sites More sharing options...
chris_tribble Posted January 24, 2010 Share #18 Posted January 24, 2010 Succinctly put sir! and it's still frustrating that Leica in its wisdom refuses to recognise what a valuable lens the 135 A-T is on the M9! Link to post Share on other sites More sharing options...
scott kirkpatrick Posted January 24, 2010 Share #19 Posted January 24, 2010 Why does the M9 support the 135 and not the 24mm frame? It does seem that the viewfinder system from the M7 was adopted intact, perhaps to avoid having to develop a new magnification. and a new set of viewfinder optics. Leica's reluctance to fully commit to the 135 seems to indicate that this is not a fully optimized solution. Perhaps we will see the zoomable viewfinder system that several have called for in the M10 and the image of its frame will be reasonable-sized. I understand that the recommendation that the 135 only be used stopped down a few stops is because the official estimate of the focusing accuracy to be expected with the M2-9's rangefinder width is less than the DOF wide open. I recently located a used 135 APO Telyt, and will soon see if this is true for me. scott Link to post Share on other sites More sharing options...
luigi bertolotti Posted January 24, 2010 Share #20 Posted January 24, 2010 M7 is available with choice of magnification (0,58 - 0,72 - 0,85) :having M9 a single kind of VF, they are limited to 6 frames/focals ... 24 to 135 encompasses 7. Link to post Share on other sites More sharing options...
