JeffreyTotaro Posted June 20, 2007 Share #1 Posted June 20, 2007 Advertisement (gone after registration) Hello: I just ordered a 15mm CV and I'm curious if people are hand coding this lens (how do you do that?) or if it's really necessary. Do you have to tell the camera that you're not coding it? In other words if I leave it uncoded do I have to change the menu when I change lenses? Thanks!

Shootist Posted June 20, 2007 Share #2 Posted June 20, 2007 Most are coding it as a WATE (Wide Angle Tri-Elmar) and then selecting 16mm in the menu option that comes up when you have a lens coded as a WATE mounted to the camera. There are several thread about coding this lens and 50-100 threads about hand coding just about any lens you can think of. Also there are numerous threads about attaching a 39mm UV/IR cut filter to the CV 15. Link to post Share on other sites More sharing options...
JeffreyTotaro Posted June 28, 2007 Author Share #3 Posted June 28, 2007 Hello: I was all set to code my M-mount adapter when it arrived today. I searched on this topic and saw that it is not possible to code it with CV adapter due to the cut-out in the adapter. What are the solutions for this situation? Is there another adapter out there? I would need to act fast as I am leaving for Barcelona on Saturday. The adapter I have is the 35 one (since the lens is not coupled and my dealer was out of the other ones). I'll continue to search on this but I haven't found it yet. Thanks! Link to post Share on other sites More sharing options...

To contact John do a search for John Milich (on this board). Cheers, Sean Link to post Share on other sites More sharing options...

lars_bergquist Posted June 28, 2007 Share #7 Posted June 28, 2007 Advertisement (gone after registration) I have used the CV15 for a long time ... I bought my first Leica in modern time (an M4-P) in order to go with it! There are two ways to use the CV on an M8: • Use it as is (uncoded, no filter). If you have other, coded lenses, you can keep the coding menu set to 'on/IR' and nothing untoward will happen. There will be no coding for vignetting (but the lens does not vignet overly much) and no correction for filter-dependent cyan drift, which is as it should be. You will have occasional cases of Polyester Purple, but mostly on minor details in the picture – this is not a portrait lens. • Code it and put an IR cut filter on it. For this you need John Milich's bayonet adapter and also his combined lens hood and filter holder. I have these on order. Any compromise is bad. Remember, coding is no great avantage in itself. It becomes one if you want to use the filter. Coding and menueing for a filter and then not using one will get you an interesting red drift in the corners. The Cosina/Voigtländer 15mm Super-Wide Heliar is a remarkable lens, and with John Milich's gear, it is the next best thing to the 16mm 1:4 prime Leica lens I have been plugging for. The WATE comes in a bad third. The old man from the Age of the Hologon Link to post Share on other sites More sharing options...

Do you have to tell the camera that you're not coding it? In other words if I leave it uncoded do I have to change the menu when I change lenses? Thanks! I use my CV 15mm coded as a WATE with a sharpie pen. It is not as fancy as the Milch adapter, but it doesn't cost $150. If the black ink wears off I just re-apply it, no big deal. I do not use an IR filter on this lens. The little vignetting that occurs is removed by the M8 and coding of the lens- and the menu choice is "Coding - ON" but not "ON- with IR filter" as that adds a magenta cast to the corners that I do not need as I don't use the IR filter. Just an alternative thought! Link to post Share on other sites More sharing options...
geoffreyg Posted June 28, 2007 Share #9 Posted June 28, 2007 There's always the simple approach: no filter, no coding. It requires fewer brain cells. And while there is some drift, I'm happy enough with it. The color in the upper left corner seems just fine, at least on screen. Welcome, dear visitor!

hofrench Posted June 28, 2007 Share #10 Posted June 28, 2007 THAT is a gorgeous image. Tell us more. I'm expecting my CV 15mm next week. It's a bit of a departure for me, since I've always pretty much stuck to the 35-50mm range. Link to post Share on other sites More sharing options...

Some more Venice images are posted at: http://www.l-camera-forum.com/leica-forum/architecture/28094-venice.html Its a great street lens. If you want to get out of the distortion, it has to be held just square, and keep a good control on the (large) foreground. But what a neat lens.Thinking about an 18 or 21, for something with a bit less reach, and a bit more foregiveness on the extreme corners (where things with the 15 can get a bit wild).
