Hi folks.
Thank you for this great forum. It's obviously a busy one and bursting with great info and stories.
I have a long relationship with Pentax gear. My father, who passed away a couple years ago, was a Pentax dedicated professional photographer and AV producer. (Remember when AV meant multi-carousel, split-screen presentations with synchronized sound and narration?) Well, he taught me the art of photography when I was a teen. I started with a Zeiss-Ikon Contaflex and couldn't wait 'til he thought I was ready for a Pentax. Finally, received a Spotmatic in 1967.
My career took a different path, but now that I am retired I'm starting make more photographs. I still have a Spotmatic, several screw mount Takumars and others. I bought a Nikon 5100 in 2011 and its been a lot of fun. I like both Nikon and Pentax equipment. Its just too bad that they are so incompatible with each other.
Anyway, here is my first question:
Right now I'm staring at a 1977 Tokina-made 100-300mm Close-Focusing f/5.0 zoom lens.
It's branded as a "Bushnell" but it appears to be identical to the one marketed by Vivitar. It belonged to my Dad and so has the M42 thread mount. It is permanently affixed with 4 set screws. According to Camera-wiki.org, Tokina made this lens for Vivitar as part of their family of 2nd generation TX II interchangeable mount lenses. If that is true, couldn't I remove the M42 mount and just replace it with a TX II P-K mount or even a Nikon AI mount?
This might be stretch here but please let me know if you have any advice.
Forever yours
