F mount adaptor at DVinfo.net

Ian Savage · June 21st, 2006, 07:37 AM

How many makers (and who) are there of F Mount adaptors for the JVC 100 series and which have the forum users well erm used actually :-) ???

Is there a Canon EOS adaptor made for the HD100 ??

I think they indicate on their site that only the Nikon is adaptable.

Does the image still has 'HD' quality using these lenses?
What about CA?

Still looks HD to me. CA varies from lens to lens.

I am having issues with internal flares using the Zoerk adapter (under some conditions the steel ring around the camera imager is kicking reflected light back into the image). You might want to try the Les Boscher adapter.

so may I suggest a very simple cure ?

go to a hobby shop, and get some flat black enamal paint (testors) in one of those little 1 oz containers, plus a small brush or two. then procede to very carefully paint the offending surfaces. obviously keep the paint at thin as possible. I assume there is some un painted metal on the inside of the adaptor. if you don't feel up to the task, any camera (video or photo) repair shop will be able to handle this for you. I know I have done this a couple of times with still camera gear to tame an internal reflection off of some bare metal surface. I guess in an emergency, even using a sharpy to blacken the offending sufaces would work, but the ink in sharpies tend to be a bit glossy when applied to non-porus surfaces

From what I understand, Canon lenses have a shorter back focus distance that won't work properly on the HD100. (It's not possible to mount the lens close enough to the prism.) Nikon F lenses, on the other hand, are just long enough for an adapter.

Steve Oakley · June 24th, 2006, 10:23 AM

actually, a EOS lens lacks an iris ring, so you would have to electronically control the iris. AFA FD glass is concerend, I have been toying around with building a FD->JVC adaptor for a while. the bigest problem is the lock lever on the camera's lens mount protrudes above the top of the lock mount. if that wasn't there, it might be possible to make an adaptor. second is that the out diameter of the canon lens is equal to the diameter of the JVC lens mount, this means these it almost no space to bring a tube forward which would connect the flange that would sit in the JVC mount, come forward, and join to a canon lens mount. In short, the physical space to make a *reliable* and sturdy adaptor is pretty much not there. the walls of the tube would be very thing, like soda can thin. I have taped a canon lens to the body and gotten focus at infinity, but I would hardly call it a usefull thing. Nikon uses a lens mount which is basically opposite that of canon, it provides a flange on the body which goes around the rear project element, which means is narrower, and can "reach" into the JVC mount to make infinity focue possible

Hi Steve,
The offending metal is not on the adaptor, it is on the HD100. The adaptor/Nikkor lens combo simply leaves it exposed. I'm a little squeamish about painting right around the imager because the metal is very glossy and I'm not sure how well the paint will stick. Maybe some electrical tape will do the trick.

Mike Pellegatti · April 28th, 2007, 06:13 PM

I saw what you said about the metal on the JVC not being covered by the Zoerk adapter and the possibility for a lens flare from a light leak. I blackened it with a product from Birchwood Casey called Aluma Black. Gunsmiths use it to touch up nicks and scratches on aluminum. I believe the metal is a magnesium frame but could be wrong, however, the product worked on it. It's a liquid and I carefully wet the folded corner of a paper towel and applied the liquid to the JVC metal and it turned it black. It won't chip off as it colors the metal like a gun blueing process. Be careful not to get it on the imager glass.

One of these days somebody is going to reverse engineer the EF mount and give us a way to stop down the lens while mounting it on an adaptor. C'mon, Sigma and Tamron did it.

Bill Ravens · April 29th, 2007, 06:27 AM

canon has an adapter. It's both powered(ie it has a piece of glass in it) and its electrically powered to drive the aperture ring. Its purpose is to be able to use EOS lenses on an XL2. Obviously, it has a canon EOS mount on one side and a canon XL2 mount on the other side. Here it is at B&H
