Tripod collar add-on for SMC 67 300/4

I'd like to balance my setup with this lens on the 645D and was looking for collars. I see a lot of them for specific lenses and was wondering if anyone had found one that would also fit this 67 lens. It's a 82mm filter and I imagine the barrel is maybe 10mm thicker.

I'll measure it more precisely if I need to but thought I'd ask in case any of you have already solved this issue and know of one that is compatible.

Thanks!

never have seen one, I don't think. You might have to find yourself a machine shop who can build you an aluminum one.

I looked into this when I owned the old 300. Not much room to add a tripod mount to this lens. You might consider the 300 EDIF. They have come down in price in the past two years.

Really Right Stuff has a lens support system that uses a "Y" bracket which provides contact at the outer end of the lens with two rubber covered steel wheels. The bracket is mounted with a couple adjustable Arca Style rails and clamps. It isn't nearly as convenient as a tripod support collar but it does work.

Thanks, I have seen those but I'm currently using Manfrotto heads and that thing looks more awkward than just dealing with a couple of mm's worth of sag.

I think the longer term problem might be the warping of your lens mount.

Initially there is a learning curve trying to figure what rail lengths and clamps are required for the specific lens-camera system and since the system is based around the Arca Standard, the tripod head needs to be Arca compatible. When adjusting the support "Y" bracket, there is a lot of leverage so care must be taken not to distort the camera lens mount. Overall the system works very well for me but there certainly is a lack of convenience as well as cost of the various bits and pieces. THe Chinese are now building some much lower cost rail and clamp components - see the B & H Listings

Thanks, I'll have a look.
I'd be pretty surprised if this warped the mount as it seems solid enough to take the stress for the amount of use it gets but I guess it is something to keep in mind.

the monfrotto support I use works well with tripod and monopod.

76mm ID Orion Telescope Tube Rings | Orion Telescopes

I used one of these telescope tube rings on the 645 A*300/4 for the short time I owned it. If there is a stationary part of the lens barrel they just slip on and you can twist the tightening bolt until its snug. There are a wide variety available from different manufacturers so you could probably find one that fits close. I'm not sure what happened with 300mm lenses and the Pentax tripod foot department but they left this necessary accessory off a lot of their lenses for a couple years.

Ooh, that looks very promising. I'll get a good measurement and probably grab one of these. Thanks!
