  • Drop in filter system for m4/3 rds

    Just seen a post about a drop in filter system for m4/3 rds cameras - don't know if anyone is interested but thought I would share

    Could be useful for 7-14 users I guess, if it works well.

      Seen this earlier but wondered how the space for the filter would still allow focus would it have pass through electronic connection or act like a tube and only allow manual?

        A very interesting idea. Almost seems too good to be true.

        Solves a number of issues with filter use but like Ed I wonder about electrical connections and normal lens functionality. If those are solved then it would certainly appeal to me.

        A question for those with better technical knowledge than me. Does the increased distance between the rear lens element and the sensor create problems?

        I've worked hard to be this grumpy. It hasn't been easy at times but it's worth it.

          My reading of it is that it's only of use with legacy lenses, as a) it has no pass-through electronics capabilities and b) as Hec wonders, it changes the flange depth.

          So, it's a legacy adaptor with a slot for filters. Wonder how it copes with ND grads?

            I think it is an adapter and at the bottom of the page it has a list of 4:
            1. Canon EF mounting lens to Sony camera E mount

            2. Nikon camera F mounting lens to Sony E mount

            3. Canon camera E mounting lens to M43 mount

            4. Nikon camera F mounting lens to M43 mount

            Not even a mention of 4/3 to m4/3 or OM to m4/3

              This would appear to be a straightforward legacy lens adapter for manual focus lenses with a greater registration distance than MFT but with a slot for drop in filters.

              My only concern is over where the best place in system of lenses is the best place to put a flat pane of glass without affecting optical quality when the system was not so designed, i.e. which end? I have an OM mount 500 mirror which takes an internal filter and it is designed to always have that filter, even if it a clear one.

              Having said that I do tend to put a filter on the front of every lens but I do know it will impact quality slightly (I think my pictures can stand it).

              Obviously it has an advantage if you are using one of the premium legacy lenses with a front element too big for a filter.

                I suggested something along this line a year or so ago on here. Having a few lenses with no filter thread or that can't take filters. If Olympus won't give us a base ISO of 12 you need rear mounting filters.
                It's the image that's important, not the tools used to make it.
