JVC GY-HD100A (E) - Canon Lenses?

Hi guys
I don't know a lot about this camera or JVC cameras full stop. I'm a XL2 user and I have lots of EF lens that I would want to sue. What lens fitting does the JVC have and is a Canon lens adapter available to take my ef lenses?

Also is the mult factor the same when using them (x7.2)

Thanks in advance for any help.

Mat I came from an XL2 as well. Put your seatbelt on.

Yes, same x7.2 "magnification"

I have Canon EOS glass and tried for quite a while to find a JVC to EOS adapter (knowing full well I'd have to adjust aperture while the glass was still mounted to the Canon). Couldn't find anyone who made one. It's such a niche market that they seem stuck on Nikons (at least that's what I found), because they have manual iris, not electronic. I know Cinevate makes EF and EOS adapter rings for their Brevis 35mm DOF adapter, but as far as simply mounting your 35mm still lenses to the JVC, you might need to get some used Nikon glass.

You can purchase(from Canon) an EOS lens mount. You can also purchase(from Fujinon or JVC) a Fujinon lens mount. What remains to be found is the focal plane distance, which should be easy to determine. Once this is done, a machine shop can mate the lens mounts on a tube of appropriate length. Care must be taken to align the mounts planar and coaxial, of course, so precision machining will be required.

I would be willing to share in the cost of developing/fabbing such an item. Perhaps others would be, as well.

By the way, Canon makes an adapter to adapt EOS lenses to the XL2. The adapter allows manual aperture adjustment of the EOS lenses by the thumbwheel on the XL2. The electrical connections shouldnt be terribly difficult to figure out.

Bill, I have a good relationship with a great machine shop through our racing. Do you think the focal plane distance might be written in some Canon spec sheet somewhere? Maybe a body mount ring to sensor spec even? Or do you think it's a start from scratch type of deal. You are right, the mount should be a breeze to have made once the proper dimensions are nailed down.

Eric...
I've never seen a published number, but, it should be easy to get, if you look in the right place. There are several ways to get it that I can think of:
1-LETUS makes a Canon EOS mount for their adapter (http://www.letusdirect.com/cart/Letu...treme-p-6.html)
Perhaps they would share the info
2-Measure the distances involved on some lenses and camera bodies(I don't like this because you would need to touch the glass and the sensor block)
3-I'm sure someone on this forum has the info, if they could share

Hey guys.

Thanks for the info. So the standard lens fixation is Nikon...ok so I could take the choice to swap to Nikon versions of my lenses...hhmmm that could be a pain. But I wouldn't need the EF adapter anymore and they can go for 150+.

Anyone draw any comparisons between this camera and the Canon XLh1 besides the cost of course :-) !?
