Hello All, Please Excuse The "caps" Bad Vision. I Recently Acquired A
Vivitar 75-260mm Zoom Telephoto Lens. It Has A Threaded Mount, And A
Pentax Bayonet Adapter Ring. The Lens Is Auto Zoom And Has A Manual
Mode Switch. I'm Using It With My Pentax K1000 Manual Body.

I'm Sure There Are A Few Things I Should Know About This Combo
That I May Not Be Able To Figure Out Myself, And Since Vivitar Was Unable
To Offer Any Tech Support, I Thought Someone In The Forum Might Be Able
To Give Me A Tutorial. Hopeful !!!
