Voightlander 15mm Heliar w/adaptor - Which M8 lens code?

I've been going back-and-forth with Carsten about the 15mm Voightlander lens he suggested I try out to get wiiiiiiiides. :)

 

I purchased the lens and the M-Bayonet Ring for 35mm and 135mm Screw-Mount-Lenses, which was the adaptor ring B&H noted would let the 15mm be used on an M Leica. (This may not be the right thing, but because the 15mm is so wide I figured the whole *viewfinder* and then some becomes my "framelines.")

 

Carsten said there will likely be some vignetting and/or drift/shift in color. I'm not terribly worried about color drift/shift, but the vignetting is something I'd like to minimize if that's possible.

 

And, the lens might just be *fine* out of the box for my purposes, vignetting and/or color shift/drift may not be so noticable as to bug me. (If it were a $3K Leica lens--or the $3K Zeiss 21mm they're talking about--it *would* bug me, BTW.) I'm only going to really be using this lens in special situations when my 35mm Summicron-M (approx. 50mm equiv on M8) doesn't cut it for wiiiiideness, :)

 

So I thought, well, *could I* code the lens adaptor ring to trigger the M8's lens auto detection so I can get some software goodness applied to the 15mm's images? I've seen a DIY procedure in the forums for coding, after all. And I've seen code lists.

 

But, I couldn't figure out which code would best match the 15mm. None of the reviews I read (Luminous Landscape, for example) or posts I found mentioned coding.

 

Carsten wasn't sure either and wanted to know--then suggested I post it--so I'm posting. :D

 

If I were going to do the do-it-yourself coding of the adaptor ring to get benefits from the in-camera processor, which "code" would I pick from the lists I've seen posted around the forums as an appropriate equivalent?

 

Does anyone know? Or have a good, educated guess?

 

Or, will it really not make a lick of difference if it's coded or uncoded?

 

Thanks!

The very best investment you can make at this point is to subscribe to Reid Reviews. He's about to publish a review on this very lens and surely will extensively handle the point of concern that you mention.

Thanks for the tip. Done. Thanks, Will.

Thanks grober. That's good to hear. With any luck, that review will be ready towards the end of February. The WA TE should be here by the 11th and I still need to finish up the 21 tests and start with the 50s.

 

Will, your best bet would probably be to use the CV 15 with a Leitz 9 cm (90 mm) adapter. The camera will then treat it as a 21/28/90. Then you can hand code the adapter as a 21/2.8 Elmarit Aspherical and that should reduce vignetting.

 

WA TE owners...what frame lines does it trigger?

 

Cheers,

Will, any adaptor will do as the lens is way wider than any of the framelines. In fact it's much wider than the entire viewfinder, so you'll need an external viewfinder. I use the 21mm viewfinder from my Voigtlander 21mm lens.

 

Vignetting isn't as bad as I was expecting. It tends to show up most on clear skies where there is pretty obvious vignetting in the corners.

This mabe works mabe not. I now is 12mm vignettes lesser on RD1 then 15mm, oba on M8 is reversal! Best I thing see how is 15mm cyan compares to some other lenses than chose adaption rink who find same frame line so when to put peint codings will respect this lens to bran of M8.

I finally got my M8

 

Now I need an old Leitz adapter that has the "full circle" so I can self code. I also need it so I can engineer an adapter for the VC units.

 

Any heip?

Hello Rex. I have the non-circular Voigtlander adapter rings as well. You will have to scour ebay and other camera stores for the old adapters. You can however use the current ones and use gaffer's tape to fill in the area. Go to this older thread ( http://www.leica-camera-user.com/digital-forum/10494-proof-concept-regarding-self-coding-lenses-13.html ), page down to the bottom of page 13 for a picture of just that. The tolerances are so tight that you have to re-try this, I would think. -Lloyd

Thanks for the tip

 

Someone machined a circular ring that fit on the VC adapter for a permanent fix. I was the thinking of doing the same but, in addition milling some ovals for coloring in the required coding.

 

Thats why I want the old adapter as more of a model as anything.

There's no "maybe" to it. I've been testing this combination already.

i tried to code a CV 21 with a 35/135 round adapter. it pulls up the wrong exif based on the right code but wrong focal length mount combination.

 

haven't tried a 9cm yet that we seem to know will let you code the 21mm.

 

will be playing with sharpies this weekend.

Hi Bill,

 

The easiest way to go is to use a 9 cm adapter. Otherwise, you'd have to hold the frame line selector in the 28/90 position.

 

Rob,

 

You could try the WA TE code. I don't have a WA TE here yet and don't know what the code is. Maybe Carsten has it?

 

Cheers,

I have a 28-90 so use the WATE code . i need to try this and I was not very lucky with my 35mm lux so i sent it out for coding awhile back.

 

Great just noticed it one black mark I should be able to hit that

maybe I'm misunderstanding various comments. but I'm not convinced the frame selector lever postion, and correspondingly, the frame coding bump on the adapter, has anything to do with the exif data.

 

I have my 15 Heliar coded for a 21 and it shows 21 in the exif data, in each postion of the frame selector lever.
