dbane883 Posted May 13, 2016 Share #1 Â Posted May 13, 2016 Advertisement (gone after registration) This may be a dumb question , but I have a 50mm Summilux 1.4 Black Chrome E43. I have searched high and low for a variable ND filter with no luck. Do you know if any manufacturer makes a vario nd filter in this size? Thx Link to post Share on other sites More sharing options...
Advertisement Posted May 13, 2016 Posted May 13, 2016 Hi dbane883, Take a look here 43mm vario ND filter. I'm sure you'll find what you were looking for!
michaelwj Posted May 13, 2016 Share #2 Â Posted May 13, 2016 You might have to go for a 43-46 step up and use a 46mm vario filter. Not pretty though. Link to post Share on other sites More sharing options...
Hayek Posted May 13, 2016 Share #3 Â Posted May 13, 2016 Heliopan and B+W start at 46mm. Link to post Share on other sites More sharing options...

david strachan Posted May 13, 2016 Share #12  Posted May 13, 2016 Variable ND filters can wreak havoc with digital sensors. That's what mine does, on testing, and pushed to the +10 setting or whatever, to the extreme. I've bought sets of ND filters but haven't ever used them. Maybe there'll be a scene one day, I'll want to Neutralize. Link to post Share on other sites More sharing options...

pop Posted May 14, 2016 Share #14 Â Posted May 14, 2016 Is this phenomenon with all variable ND filters irrespective of the maker? No, it is not. I have a variable ND filter and have so far not been able to provoke that efffect, unless I set it beyond the maximum value indicated on its frame.

The aforementioned filter on a Jupiter-3 lens, all shots at 1:1.5, exposure set to automatic. The first shot is exposed for 1/500 sec, the last one for 4 sec.  1/500 Welcome, dear visitor!

Hayek Posted May 15, 2016 Share #17 Â Posted May 15, 2016 No one has spoken of B+W or Heliopan; are all polarizers created the same, resulting in the identical artifact? Â This is a real bummer. I have a 2-stop Heliopan I use with my Summicrons for B&W and wanted to get the variable for convenience. Link to post Share on other sites More sharing options...
pico Posted May 15, 2016 Share #18 Â Posted May 15, 2016 No one has spoken of B+W or Heliopan; are all polarizers created the same, resulting in the identical artifact? Misunderstanding. The variable ND filters use two polarizing filters in opposition to each other to create an ND filter and sometimes cause the artifacts already noted. Â Straightforward (linear) polarizing filters are one layer. Circular polarizers add a 1/4 wave filter. Circular is the way to go if you use autofocus. Neither will cause the artifacts noted so far. Neither will straight ND filters. Â So, circular and nd is good. Enjoy! Link to post Share on other sites More sharing options...
