mustafasoleiman Posted July 11, 2007 Share #1 Posted July 11, 2007 Advertisement (gone after registration) This is probably mentioned somewhere else but I could not find it... I need a wider angle than my summicron 35 asph. I think the summicron 28 asph is too close and too expensive for the small step back. The WATE would be an ideal solution, but it's either that or a vacation this summer for my family... So I am looking into the CV12 or 15. My questions are: Are they both screw mount? I have an old leitz screw to M adaptor, would it work? Do they need to be coded? Do they need to have the IR filter? If I use them as they are (except for the screw to M), shooting in colour, what problems will I face? Also the viewfinder will need to be a size higher, correct? What are my options? I am leaning towards the CV15 for size and cost. Many thanks for any advice. Link to post Share on other sites More sharing options...

Philippe D. Posted July 11, 2007 Share #2 Posted July 11, 2007 Hi Mustafa, Are they both screw mount? I have an old leitz screw to M adaptor, would it work? - Yes Do they need to be coded? - Not especially, but it could help some times. Do they need to have the IR filter? - Same as above. If I use them as they are (except for the screw to M), shooting in colour, what problems will I face? - Vignetting. Could be resolved on the computer with software. Also the viewfinder will need to be a size higher, correct? What are my options? - The 21mm viewer. I am leaning towards the CV15 for size and cost. - I have the CV12mm (because i also have a 17mm Rokkor), the CV15mm (as a 20mm) is a good choice for Super Wide angle without the strong effects of the 12.

farnz Posted July 11, 2007 Share #3 Posted July 11, 2007 Mustafa, To add to Philippe's comments, John Milich (jlm) manufactures LTM to M mount adaptors with 6 milled pits at the right position for encoding. You only have to fill the appropriate pits with black or white paint for the M8 to recognise the coding. There are many threads that cover this matter. If you decide to code the lens mount you'll probably want to use a 39mm Leica UV/IR filter so you can use the M8s IR filter ON option to control vignetting and cyan drift. There are a number of threads about fixing the filter to the (unthreaded) CV 15 lens but John Milich has also started manufacturing an excellent filter holder and lens hood. Personally I use a small strip of self-adhesive rubber on the built-in plastic hood, which keeps the filter firmly in place. (The filter needs to be inserted back to front or it will touch the front element.) The CV 15 is normally supplied with the Voigtlander 15mm viewfinder, which appears to be brighter than the Leica vfs. The M8's 1.33 crop factor means that you will see more in the vf than the M8 will capture with the CV 15; I've used 0.5mm wide masking tape as framelines and converted the 15mm vf into a 21mm vf. (The only difference AFAIK between a Voigtlander 15mm and 21mm vf is the addition of framelines by the manufacturer.) Pete. Link to post Share on other sites More sharing options...
chris_tribble Posted July 11, 2007 Share #4 Posted July 11, 2007 CV 15 is a brilliant little lens. Mine has a coded Milich screw > bayonet adaptor and I'm getting the filter holder + hood. Example of how it works below (part of a series on the Anthony Gormley work on London's South Bank. BTW - re needing to step down from the 35 - the 15 is a VERY big step. Worth looking at 21 if you can find one that's afforable... In the pair I'm attaching, the first uses the 35 FOV, the second the CV15 (comes up as 18mm in the Exif) Best Link to post Share on other sites More sharing options...

Cindy Flood Posted July 11, 2007 Share #7 Posted July 11, 2007 Advertisement (gone after registration) Mustafa, You might want to check with John Milich. If your adapter is a 9 cm Leitz, I think that he can put the indents onto your adapter for a very reasonable fee. I would read Sean Reids reviews (if you haven't). He has very good information on these lenses that you are considering and he details what accessories are needed for what circumstances. Link to post Share on other sites More sharing options...
Tony C. Posted July 11, 2007 Share #8 Posted July 11, 2007 Mustafa, I haven't tried the 12mm CV yet, but the 15mm is excellent. Here's a link to a representative shot taken in NYC, no coding, no filter: midtown tunnel Regards, Tony C. Link to post Share on other sites More sharing options...

I wanted to say that but didn't want it to sound like an advertisement. The info./tests on all this stuff, for many RF lenses, adapters, etc., is all on the site. Just a reminder to folks that the 12 is better left uncoded if one is going to use it for color work with IR-cut filters. Cheers, Sean Link to post Share on other sites More sharing options...
