Lals Posted December 3, 2014 Share #1 Posted December 3, 2014 Advertisement (gone after registration) Hi, Any recommendations for a ND filter or even a variable ND filter for the 50 APO? I looked online at BH and it looks like there are no ND filters available that with will fit Leica front lens diameter of 39 mm. Do any of you use one? Does it always require a step ring? Can you use a lens cap with it? I was thinking to get a good quality variable ND filter that I can just leave it on the camera when I am shooting in bright daylight ..say mexico on the beach.

Nr90 Posted December 4, 2014 Share #2 Posted December 4, 2014 (edited) B+W sells 39mm ND filters. The same lens cap as without the filter should work. Example: http://www.bhphotovideo.com/c/product/8038-REG/B_W_65073011_39mm_103_Neutral_Density.html Edited December 4, 2014 by Nr90 1 Quote Link to post Share on other sites More sharing options...

Jeff S Posted December 4, 2014 Share #5 Posted December 4, 2014 So you bought the APO? Would be nice to check back in on this thread so folks know. Also haven't seen you back here. In case it's helpful, prior threads and posts can be accessed by clicking on your user name, then 'statistics'. Easy to forget what you started.

Lals Posted December 4, 2014 Author Share #6 Posted December 4, 2014 These are Schott glass.. nice! but any that are variable stop ND filters? Would prefer to get a single one that can go multiple stops. Quote Link to post Share on other sites More sharing options...
Lals Posted December 4, 2014 Author Share #7 Posted December 4, 2014 Advertisement (gone after registration) Hi Jeff, I checked back in..

Jennifer Posted December 4, 2014 Share #8 Posted December 4, 2014 I had a similar conundrum when looking for a suitable ND filter to use with my 35 & 50 Summilux lenses. Since both these take 46mm filters a variable ND filter was an option, however, I eventually plumped for a simple B + W 3 stop filter and up to now I can't say that I've ever encountered a situation where I couldn't manage perfectly well with that one strength alone.

michaelwj Posted December 4, 2014 Share #9 Posted December 4, 2014 Hi, Variables aren't traditionally used in Leica world - remember they M5 was the first with TTL metering, before then they were useless, or even now with an M-A. They're usually a bit thicker so might vignette a bit too. You don't need to take all of them with you, depending on the day either a 3 or 6 stop would be fine. I have a 3, 6, and 10, but never carry them all at once - its usually dictated by film speed. I'd suggest starting with a 3-stop, that gets you from f/8 to f/2, pretty useful really. On the other topic, sounds like you bonded with the APO more than the 'lux? Cheers, Michael Quote Link to post Share on other sites More sharing options...
Lals Posted December 5, 2014 Author Share #10 Posted December 5, 2014 Thanks all. I think I will go with a 3 stop ND filter for now. Quote Link to post Share on other sites More sharing options...

Showing my own stellar maths skills, it actually gets you from f/5.6 to f/2 (5.6-4-2.8-2). Doh. Still my most used though. Michael Quote Link to post Share on other sites More sharing options...
a911s Posted December 5, 2014 Share #12 Posted December 5, 2014 Hoya Pro ND is the most neutral. Quote Link to post Share on other sites More sharing options...

Michael Do you find this more useful than a 4 stop to go from f/8.0 to f/2.0? Just asking because I am looking to get one, only one and wondering if this would be more useful.

algrove Posted December 6, 2014 Share #14 Posted December 6, 2014 Leica had Heliopan do a special run of VND filters size 46 & 60. I bought a step up 39-46 and when needed use the 46 VND on the APO 50. Quote Link to post Share on other sites More sharing options...

Just asking because I am looking to get one, only one and wondering if this would be more useful. I don't know who makes a 4 stop, but I've never been wanting more than 3 in typical use, even with a film M. The 6 stop is useful when I'm mid way through a roll of 3200 and its now daytime, I don't tend to use it with 400 film much, never with 100.

Actually B&H has 4 stop filters by Heliopan and Formatt Hitech in 39mm. Quote Link to post Share on other sites More sharing options...
M11 for me Posted June 29, 2017 Share #17 Posted June 29, 2017 This is an old thread though. But in thr meantime we habe 4-Stopp ND-Filters that match the 50mm Lux and at the same time the 28mm Cron. As 4Stops is not too much I just bought 2 to mount on top of each other to get a 64x filter. The 2 together work well on the 50mm whereas on the 28mm the might create vignetting. First tests show that the 2 together are not "neutral" any mure but create color shift to blue. This can easily be corrected in lightroom though. But still: This disappoints. Does someone have ecperience with these filters on an M10. Does someone use 2 together? Furter the M10 can automatically exposure up to 125 seconds. But still my arrow blinks when looking through the finder. How do you manage that? Quote Link to post Share on other sites More sharing options...
