question

Can this fit on a Ef mount or a Nikon D800 camera?What format is this lense for?
Asked by: Anonymous
The 21mm f/1.4 Summilux-M Aspherical Manual Focus Lens has the M-Mount. It would not be compatible with Nikon or Canon DSLRs. It is compatible with Leica, Voigtlander, and Zeiss M-mount rangefinders.

How can I install the filter? Under the hood?

How can I install the filter? Under the hood?
Asked by: A
Yes. There is room under the hood for a special series filter which is made by Leica. It is not threaded but just sits in the space.

question

What size should be the filter(s) to be used with this lens ?
Asked by: Denis L.
You can find the Series 8 filters on BH by searching for ND filters and then scrolling down to the bottom of the filter size list. They are at the bottom of the list. I use the 0.9 (three stop) filter. The reason for the special filter is that they sit behind the lens hood and are not screwed on. There is a slight noise (do to movement of the filter) which is normal. With the M (240), you can leave the filter on and simply switch between ISO 200 for outdoor photos in daylight and ISO 3200 for evening or indoor photos. (Kudos to Thorsten Overgaard!)
