bingaloid Posted June 4, 2007 Share #1 Posted June 4, 2007 Advertisement (gone after registration) Hi all, Has anyone tried fitting a Leica filter on a CV Nokton 40/1.4? Is the right one Part# E43? Thanks, David Link to post Share on other sites More sharing options...

furcafe Posted June 4, 2007 Share #2 Posted June 4, 2007 I don't have a Leica filter in 43mm, but I believe the CV 40/1.4 has a standard 43mm (E43) thread. I have no problems mounting a B+W 486 filter to it. Hi all,Has anyone tried fitting a Leica filter on a CV Nokton 40/1.4? Is the right one Part# E43?

bingaloid Posted June 4, 2007 Author Share #3 Posted June 4, 2007 Thanks! I'm pretty sure too, but I thought I should do a sanity check before putting in the order (or the backorder really). - david Link to post Share on other sites More sharing options...
howard_cummer Posted June 4, 2007 Share #4 Posted June 4, 2007 I use a heliopan ES 43 Digital UV / IR filter on my 40f1.4 SC and have hand coded it so that the M8 reads it as a 35 Summilux Asph. The combination works like a charm. The coded dots (painted on with matt black modelling paint) tend to wear off and have to be renewed from time to time. In my experience the 40/1.4 is a great lens and ideally suited to the M8. Also, I filed down the claw on the bayonet so that when mounted the lens brings up 35mm frame lines - which provide loose but acceptable framing for the 40 Cheers Howard (in Hong Kong) Link to post Share on other sites More sharing options...
bingaloid Posted June 4, 2007 Author Share #5 Posted June 4, 2007 Thanks Howard, I'm glad to know it's working well for you. I've got a project coming up shooting cyclists in a really small storefront, so I think the 40 is going to work nicely in combo with a 28/2 - but the lighting in there is really weird so I'm going to need a filter. On the filter front, since both the B+W and the Leica filters are in such demand I figured I'd just go for the Leica since consistency is my best friend in photography and all my other IR filters are Leica brand. I'm curious about the filing/dremel process, but essentially doing something like that scares the bejeezus out of me so I haven't done it. Link to post Share on other sites More sharing options...
robsteve Posted June 4, 2007 Share #6 Posted June 4, 2007 The Leica 43mm filter may not be a standard E43. A few people have posted it doesn't fit on third party lenses. The 43mm Leica filter was made for the older 50mm Summilux and may not be 43mm x .75mm used on modern lenses. Link to post Share on other sites More sharing options...
bingaloid Posted June 4, 2007 Author Share #7 Posted June 4, 2007 Advertisement (gone after registration) Oof. I've actually read conflicting reports about it but came to the conclusion that it _probably_ would work, or at worst would only screw on half-way. I've already hit the submit button on the order, so I guess I get to find out the hard way - or maybe I'll try to cancel. Either way, thanks for heads up!

robsteve Posted June 4, 2007 Share #8 Posted June 4, 2007 I just checked a list of lenses and the filter is 43mm x .5 pitch. It isn't until the 49mm filters that Leica goes to .75 pitch. The cameraquest site does not show the thread pitch for the 40mm Nokton. Leica-M lenses Voigtlander RF Leica Mount Lens Chart Link to post Share on other sites More sharing options...
bingaloid Posted June 5, 2007 Author Share #9 Posted June 5, 2007 I'm assuming the threading on the Nokton is .75 since it fits other known standard filters, like the B+W and Heliopan. I also looked through those two tables, but couldn't come up with a definite answer either way. Hmmmm... EDIT: It looks like a little creative Googling would have helped me, Leica and Rangefinders Forum: E43 to 46mm Step Ring? - photo.net (look 2/3 of the way down the thread) Only thing is I didn't know exactly what I was looking for. Thanks for all the help, now I have to see about changing my order. - David Link to post Share on other sites More sharing options...
howard_cummer Posted June 5, 2007 Share #10 Posted June 5, 2007 The heliopan 43mm #8025 screws on all the way on the Nokton 40's threads so must be the right pitch for this lens. Link to post Share on other sites More sharing options...
bingaloid Posted June 5, 2007 Author Share #11 Posted June 5, 2007 Thanks Howard! The only place in the US I can find the filter is at Cambridge, and they only have B+W. I guess I'll know tomorrow if it's actually in stock. - David Link to post Share on other sites More sharing options...
Artichoke Posted June 5, 2007 Share #12 Posted June 5, 2007 I received the E43 Leica filter as one of my two freebees it fits perfectly and the nifty lens hood for the Nokton fits over it as well, which is not the case for the BW polarizer I got for the 40 Nokton ...with the filter on, the hood wil not mount and with the hood on the BW polarizer cannot be attached however mounting the polarizer atop the Leica IR/cut allows the hood to be used as the threads on the Leica are free ...how effective this combination works is something I have yet to test, though the results I got using both a polarizer and ir/cut with my 21 Elmarit are promising I am still waiting on the 60 mm from Leica & then I can rest for a bit hope this helps Link to post Share on other sites More sharing options...
bingaloid Posted June 5, 2007 Author Share #13 Posted June 5, 2007 Wow, Arthur, you've really saved the day. Great to know it's a good fit, my original plan is back on! [This forum never ceases to amaze me] Link to post Share on other sites More sharing options...
