A 300mm F4 Tripod Mount

Looking for a 300mm lens with a tripod mount. I know the FA has one but it's considerably more expensive than the A version. Doesn't sound like there is any real difference in IQ and I'm good with manual focus so if I can save some bucks....

The A series 300/4 is a pretty small lens, it does not look like a 300. I don't think it ever came with a tripod collar, and I'm not sure where you would mount one.

Evening,

I have the same lens (A* 300/4) and went through the same search (for some reason I miss typed an M for an A). The information is down at the bottom of the thread....Actually, as I get older - I have found that my eyesight is not conductive to manual focus, especially for the longer focal lengths. Earlier this year, over the holidays, I picked up a 60-250 with the 1.4x teleconverter.

The one thing I can say on this setup, is that you need a rail that supports a front mounted assembly. Hence the screw hole on the leading edge. There are only a couple of vendors that support this.

Sorry, should've specified; 645 A 300mm. This lens is longer and heavier than the DA 300, which has a tripod collar. Thanks

Have you looked at the RRS setup? They offer a very solid rail which is good for the 645Z and long lens. I looked at mine, but there are no part numbers on the rail nor on the roller extension.

Hi!

I use this 'Canon tripod mount ring A(W) 70-200mm.F2.8' on my 645 A*300/4:

It's a little to wide, my quick and dirty solution was some electric insulation tape
