samuelphoto Posted January 1, 2011 Share #1 Posted January 1, 2011 (edited) Advertisement (gone after registration) Hello all and happy new year. I'm posting this question in hope that others maybe have tried a simliar option on the Voigtlander 15mm Heliar in M mount with the 52mm filter mount. I'm considering purchasing this lens but am in a bit of a quandary as to how to best attach a UV/IR filter. I am aware that Leica's are the best choice for ultra-wide lenses, but they do not produce a 52mm filter. So, I'm considering a 52/55 step-up ring with a Leica E55 UV/IR filter and maybe also a 55/58 step-up ring on top for a little added protection. Of course this means I would not be using the factory shade which I am OK with. I'm hoping this combination won't vignette and won't impair my ability to focus through the camera viewfinder, though I will be using an auxilliary viewfinder mounted on the hot shoe. What do you think of this option? I guess there is also the possibility of stepping down to use a 49mm filter, but I'm skeptical about that option. Can you recommend a more elegant solution that will still allow use of a Leica UV/IR filter? Thanks in advance for your help.

Islandmike Posted January 2, 2011 Share #2 Posted January 2, 2011 I needed a 52mm UV/IR filter for a CV Nokton 50/1.5 and purchased a Marumi 52mm (new) from Hong Kong on ebay. It works absolutely fine for me with no image degradation that I an see. I have seen reports in the forum that Marumi is the same glass as the Leica version, but could not make any comment on that. The mount is not quite as nicely made as the genuine Leica filters I have in 39mm size, but perfectly satisfactory. Price was around £30 = USD 45. I noticed also that B+W make a 52mm. For an elegant solution, I guess either of these two must be tops. Hope this helps. Cheers Mike Quote Link to post Share on other sites More sharing options...
samuelphoto Posted January 2, 2011 Author Share #3 Posted January 2, 2011 Thanks, Mike, I will look into the Marumi filter. B+W uses a different technology than that used on the Leica. They even state on their web site their 486 filters are not suitable for lenses wider than 24mm. Quote Link to post Share on other sites More sharing options...
epand56 Posted January 2, 2011 Share #4 Posted January 2, 2011 Mike, when I bought the CV 15mm M mount, I've also bought a B+W 52mm UV/IR filter and screwed it on the lens. I've then permanently coded it (you can do that because of the groove in the mount) as a WATE and had no problems since. The B+W filter works great and the lens itself is a bomb.

samuelphoto Posted January 2, 2011 Author Share #5 Posted January 2, 2011 Enrico, it is interesting to hear you say the B+W filter worked well on this lens. I've read, and even the B+W web site says, that it shouldn't be used on lenses wider than 24mm. I don't remember the technical details, just the result. Seems you are pleased with it though. How does this combo work with the lens wide open? Quote Link to post Share on other sites More sharing options...
epand56 Posted January 2, 2011 Share #6 Posted January 2, 2011 Samuel, I had serious problems on my CV 12 where a B+W UV/IR was not only useless but gave me unpleasant results. I found the solution with another B+W filter, the IR blocking filter 489. With it on anithing was perfet. But the B+W filter (UV/IR) and the WATE coding on my CV 15 (I mainly use WATE16) is a very good combo to me. Here you are a couple sample, CV 15 (wide open) first and CV 12 second. 1 Quote Link to post Share on other sites More sharing options...
deirdre Posted January 3, 2011 Share #7 Posted January 3, 2011 Advertisement (gone after registration) I've used the B+W 52mm UV/IR filter on a 15mm CV with good results. Example I've posted before: Quote Link to post Share on other sites More sharing options...

WestMichigan Posted January 5, 2011 Share #9 Posted January 5, 2011 Hello Enrico- you've shared a couple of very nice images! Thanks for doing so. Query: How far do you think you were from the family in the 2nd photo when you shot it? I'm contemplating getting one of those CV Wide Angles when I get my M8. I'm not usually a wide angle guy, but I chalk that mostly up to never having been able to get 'good glass' to make shots that were worth a D@MN as anything other than touristy snapshots. Which I'm not above taking, but I'm capable of & aspire to be more than a few notches above a 'snap shooter'!

epand56 Posted January 5, 2011 Share #10 Posted January 5, 2011 Query: How far do you think you were from the family in the 2nd photo when you shot it? Richard, thank you for your comment. I was far more close to them than you could imagine looking at the picture. I do not remember very good but it was no more than three and a half meters (around 12 foot). This lens is outstanding. I took the picture of the people at the book fair without taking the camera to the eye. It is quite usable even in mild light conditions. On the M8 it is almost a 21. This example is in very low light (you can almost read the paper). Best regards, Enrico 1 Quote Link to post Share on other sites More sharing options...
samuelphoto Posted January 5, 2011 Author Share #11 Posted January 5, 2011 Based on everyone's helpful comments, I just ordered the CV 15 in M mount with the B+W 52mm 486 filter. I'll let you know how it goes soon. Quote Link to post Share on other sites More sharing options...

brunop Posted February 24, 2011 Share #13 Posted February 24, 2011 quick question. should i get the hotshoe viewfinder for the 15mm lens? thanks! Quote Link to post Share on other sites More sharing options...
deirdre Posted February 24, 2011 Share #14 Posted February 24, 2011 Unless you want to frame the shot by successive chimping, yes. Quote Link to post Share on other sites More sharing options...
brunop Posted February 24, 2011 Share #15 Posted February 24, 2011 one more question--is there a difference between the round one and the squareish one? thanks! Quote Link to post Share on other sites More sharing options...
