Guest 3ldfilms Posted January 6, 2006 Share Posted January 6, 2006 Can someone describe the difference between an Arri bayonet and standard mount. Being primarily a director I have not paid much attention to the mounts in the past, but I just got a Super 16 K-3 with crystal motor and Arri standard mount. I'm looking to get a couple of extra lenses. Can one get adapter between bayonet and standard? Link to comment Share on other sites More sharing options...

I'm looking to get a couple of extra lenses. Can one get adapter between bayonet and standard? An Arri Bayonet mount lens like the Optar Illuminas I have, has two little metal parts which protrude out of it on opposite ends (its easier to show a picture than describe it.) On my ACL they go into an adapter that has room for these two parts. The adapter which I got from Les Bosher, has a locking mechanism to hold the lens in place. I used to have an Arri Standard lens, the Angenieux 10-150. It didn't have the metal parts jutting out of the side, but went into the mount straight, and you would tighten it up once it was seated in the hole. Here are a couple of links which give much more lucid descriptions of these mounts: http://www.cinematechnic.com/resources/arri_16bl.html Look under lens mount. Also try: http://www.rondexter.com/professional/equi..._and_mounts.htm Hope this helps, Mike Link to comment Share on other sites More sharing options...

Both mounts have the same flange depth and diameter. The two nobs on the bayonet give the lens a more secure grip, but prevent the bayonet mount from going into the standard recepticle. ---LV Link to comment Share on other sites More sharing options...
Mark Dunn Posted January 7, 2006 Share Posted January 7, 2006 Are you sure it's an Arri Standard mount? My K3 has a bayonet but I think it's proprietary. The flange focal depth and mount diameter don't seem right. Link to comment Share on other sites More sharing options...

The flange focal depth and mount diameter don't seem right. When Du-All does there upgrade they also switch the mount to Arri Standard which is both a blessing and a curse. I have a couple of Pentax Super Takumar lenses that are great on K3s (even though they are 35mm still lenses) that I can't use any more.
