    Found this great site that rreviews all Olympus Zuiko 35mm FF lenses... http://www.mir.com.my/rb/photograph...olympusom1n2/shared/zuiko/htmls/indexzoom.htm - scroll down to see the full list...

    Was looking at the 18mm UWA and saw thay had a innovative filter solution...the lens has a 49 dia filter thread to which you screw on a 49-72 adapter and then mount the filter. This lens has a 100 deg angle of view, so the same could be done for an 8mm m43lens... http://www.mir.com.my/rb/photography/hardwares/classics/olympusom1n2/shared/zuiko/htmls/18mm.htm

    Also had a look at the 16mm full frame fisheye and saw that they built 3 optional filters into the lens... http://www.mir.com.my/rb/photography/hardwares/classics/olympusom1n2/shared/zuiko/htmls/fish16mm.htm

    Was also amazed at how small and light these lenses were.

    If only Oly/Pan/Others would adopt similar solutions today....

    I was actually playing with a used 7-14 in the camera store today, Sadly the edge of my Lee Seven5 Grad filters show up at the very far edge of the lens at 7mm while handholding it in front. Maybe if I shaved off some of the top/bottom lens shade it would work? The straight ND filter worked if tilted to the side, but let in a lot of reflections, I'd need a way to stop light from getting in between the sides and the filter. I'd really like to get a UWA that at least took some form of ND or Grad ND, and I don't feel the 9-18 offers enough extra width when I already have the 12-35. I'll probably be selling my 9-18 soon.

    I would think that a rear filter solution would be the best way to solve the problem. That's what I did with my Rokinon 8mm fisheye lens.

    You could use a rear filter for a normal ND or maybe UV filter, but not for something like a graduated ND

    Could you elaborate on your 8mm filter?

    I have thought about adding a gel filter holder from the Panasonic 8mm fisheye to the back of my 7.5mm (not uncommon on UWA lenses) but perhaps there are alternative solutions I have not considered?

    This is the best solution I've seen to date.

    Filter holder for P 7-14

    I made my own filter holder for the Panasonic 7-14.
    I used an original lens cap glued it into a 77 mm Cokin P lens adapter using 2 part epoxy.
    I then removed the "cap portion" of the cap on a lathe.
    There is no vignetting even at 7 mm when using the outermost slot in the Cokin P filter holder.
    The only mod needed to the lens itself is a strip of gaffer tape to compensate for the barrel diameter getting smaller towards the camera.

    Someone could probably make some bucks on this with a 3D printer.

    The present.
    This is pretty much what I did with the same results. Best solution, I need the gel holder in the back of the 7-14mm for the yellow 2a to neutralize the purple blobs on my EM-5. heh.
