macusque Posted January 20, 2007 Author Share #21  Posted January 20, 2007 Advertisement (gone after registration) god job Marco. Verona is one of my favorite places in Europe. I have worked at the colliseum there and it is a truly fantastic music venue. Keep the images coming...b  Hi Bradley! The Arena in Verona is indeed an amazing place which is still nicely kept alive. Let me know if/when you come here again!  Btw, Kiwi state is always in my dreams... one day I'll fly there for sure! Link to post Share on other sites More sharing options...
Advertisement Posted January 20, 2007 Posted January 20, 2007 Hi macusque, Take a look here IR-CUT filter on 15 Voigtlander. I'm sure you'll find what you were looking for!
J_Brittenson Posted January 20, 2007 Share #22 Â Posted January 20, 2007 Excellent! I have a silver 37mm and a black CV 15. We could have traded! Â I got the 37mm filter to use with a 36-37 step up ring with my Summitar, but the step up is too fat to fit. Glad to have found some use for that filter after all!!!

macusque Posted January 20, 2007 Author Share #23  Posted January 20, 2007 Hi Jan!  I'm glad you found a way to use your filter  This lens is a little gem, isn' it ? It's funny how small the M8+15CV combo is compared to the 1Ds+21 Zeiss... do you remember ? Link to post Share on other sites More sharing options...
Vivek Iyer Posted January 20, 2007 Share #24 Â Posted January 20, 2007 Rear mounted IR cut filters on CV 15 causes focus shifts (infinity focus is around 1 meter or so) and reduction in sharpness ( i think due to my inability find the infinity focus correctly) on an R-D1s. Â Have you noticed any drop in sharpness with the front mounted IR cut filter? Link to post Share on other sites More sharing options...
macusque Posted January 20, 2007 Author Share #25 Â Posted January 20, 2007 Have you noticed any drop in sharpness with the front mounted IR cut filter? Â No, focus is perfect and images are sharp. I need to stop down the lens to f/6.3-f/8 for optimal sharpness at edges, but this is typical for the 15 CV. Link to post Share on other sites More sharing options...
marknorton Posted January 20, 2007 Share #26 Â Posted January 20, 2007 Verona is a glorious place, pleased to say I have tickets for the opera there in the summer. Leica prices though LOL. Â Marco, do you think a 39 filter would work as well? I've used my calipers to measure it and the internal diameter is exactly 41mm. Maybe a slightly larger filter would be easier to secure. The inside of the "hood" is serrated, so a thin strip of neoprene rubber glued around the filter would allow it to press into the front of the lens and stay in place. Â As regards coding, you could also code it with the WATE code, though we'll have to see how that works with firmware 1.10. We still have the issue of the adapter not covering the sensor though.

macusque Posted January 20, 2007 Author Share #27  Posted January 20, 2007 Advertisement (gone after registration) Mark,  a 39mm filter would be even better, providing you can tape it to make it fit tighter so that no silicon is needed. I don't know if it could fall off the lens at certain angle though, but it is surely an easier method  I still have to look at self-coding, I already downloaded Carsten's list and I printed the template but I still have to do the handwork... I noticed that the bayonet on the 15CV adapter is rather narrow, I hope the sarpie method work there. Link to post Share on other sites More sharing options...
robsteve Posted January 20, 2007 Share #28 Â Posted January 20, 2007 Robert, did you manage to mount it without the silicone, maybe using a tape on the ring to make it more tight in place ? That would be an even better solution indeed ! Â I think if a bit of felt was put on the hood tabs, the filter would fit tightly. If you put the filter on upside down, it does not hit the fron element. I don't have my M8 yet to test if the filter orientation makes any difference.

It's funny how small the M8+15CV combo is compared to the 1Ds+21 Zeiss... do you remember ? Yes, it's a great lens! And yes, I remember the CZ 21... nice lens but man is it ever hefty.

doubice Posted January 20, 2007 Share #30 Â Posted January 20, 2007 .....Marco, do you think a 39 filter would work as well? I've used my calipers to measure it and the internal diameter is exactly 41mm. Maybe a slightly larger filter would be easier to secure. The inside of the "hood" is serrated, so a thin strip of neoprene rubber glued around the filter would allow it to press into the front of the lens and stay in place...... Â I tried 39mm, 40mm and 40.5mm filters. The 39mm is the largest one that will fit inside the shade. The 40mm filter might be made to hold by itself, but it would be too far from the front element and parallelism would not be guaranteed. Also - 40mm filters are scarce as hen's teeth, mine is a leftover from my Canon rangefinder days. Â Robert, this is good news - when my M8 arrives I am looking forward to use the CV 15mm Heliar on it, along with a Canon 3.5/25mm lens.

doubice Posted January 20, 2007 Share #31 Â Posted January 20, 2007 .......Mark, I noticed that the bayonet on the 15CV adapter is rather narrow, I hope the sarpie method work there....... Â All the Voigtlander adapters, as well as the majority of the Leica ones have a cut-out along the bottom perimeter, making them difficult to hand-code. This was originally done by Leitz so that the infinity lock of all early LTM Elmars could clear the adapter when pressed down. Â As Sean mentioned, some early Leica adapters for the 90mm lenses did not have this cut-out and would be much easier to hand-code. Boy, am I glad to be a pack rat......... Already dug up three of these oldies out of my 'I don't need this now but you never know' drawer. Â All the best, Â Jan Link to post Share on other sites More sharing options...

J_Brittenson Posted January 20, 2007 Share #33 Â Posted January 20, 2007 What I did with my setup was to cut out four slivers of double sided adhesive foam, and attach to the filter in the four directions where there is some hood. Then work the filter with pads in all the way, so the filter is held in by the foam bits in four directions. The adhesive keeps things from slipping. Works great. Took a little careful work to get it all the way in. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted January 21, 2007 Share #34 Â Posted January 21, 2007 Thanks Jan that sounds like a good way to install it in. I ordered one and hopefully it is not backordered from Adorama Link to post Share on other sites More sharing options...
rvaubel Posted January 21, 2007 Share #35  Posted January 21, 2007 Hi Sean, with "9cm Leitz adapter" you mean a particular screw - to - M-mount adapter ?I use the one from Voigtlander and indeed it seems too small to accomodate the sharpie method. Maybe the Leitz adapter is wider ?  Yes, the older Leitz adapters can be self coded because they don't have the "cutout" that prevents modern adapters from being coded. If this self coding thing takes off, I'm sure one of our enterprising Chinese importers will fill the void  Rex Link to post Share on other sites More sharing options...

chris_tribble Posted January 21, 2007 Share #40 Â Posted January 21, 2007 I just tried the 39mm 486 filter and it too fits inside the Voitlander 15mm hood. Â Same trick with a Hoya 39 filter ring I had floating around. This sort of clips in so should even easier to use. I've got the 39mm 486 on order so will able to swap between my 35mm Cron and the Voigtlander... a solution at no additional expense. How nice. Â I also agree with others who comment on the need for the IR cut filters at all time for colour work - my experience outdoors in cloudy and sunlit conditions with those lenses for which I have filters (currently 21 pre-asph elmarit / 50 pre-asph lux) compared with those that don't is proof positive enough for me.
