Tripod Collar

I got the 150-450 lens for Christmas which I am thoroughly enjoying. I'm having trouble removing the tripod mount for the first time from the lens. The locking knob becomes fairly tight after a few turns. Before I apply substantial force can the mount be removed and is it done by loosening this knob?

To remove the foot (not the collar, which stays in plac), here's what you do:

loosen the knob on the foot (not the one on the collar).
push on the knob (which has become a button)
slide the foot to the front

You're done.

welcome to the forums

do you have the manual for the 150 - 450 lens. if not, this is how I got my copy

I bought mine used but in excellent condition. came with everything except the written manual

Download operating manuals - RICOH IMAGING EUROPE S.A.S

select "k mount" in the "product group" code box

select lens model in "product" box

hit search and select the language you need

please take a look at this thread and let us see how you handle the "big guy" (as I call my 150 - 450)
