Dear Lowell Goudge:
The PIPE Here again (just been calling around to TRY getting some sort of CAD work to do for income!)....
...and from the attached photo of my Vivitar, you'll see it's UNmodified...it EASILY fit on my K100D, just about as easily as it always has on my K1000SE "film burner"...!
I got that lens, a LOONG time ago, from the well-known KEH.com website for used camera gear. I traded them my Pentax 200mm f/4 prime lens to get it, and got a "one-touch" tele zoom that's slightly LARGER in maximum aperture than the Pentax "prime", and with a macro capability on top of that! I had ALWAYS wanted one of them, after seeing one in 1984 in the photo department of the now long-defunct "Lechmere" department store in Weymouth ("Lechmere" was a Boston area chain of department stores)...and thanks to KEH, I got just about the best model of the Vivitar S1 made in that focal length...the ORIGINAL model of it, all f/3.5 of it, too!!!!
I'd LIKE to get a rubber lens hood for it, partially to protect the front of the lens (a possible candidate is listed at
Hama | 67mm Screw-In Rubber Zoom Lens Hood for 24mm | HA-929.67 )...but that's got to wait for more CAD work to come along...!!!
I haven't YET tried doing RAW shooting with my K100D...that MIGHT take a good editing software package like Bibble Pro to get decent post-processing results...and
I would LOOOVE to get a
Sigma 135-400 DG autofocus tele lens (which I've nicknamed the "Li'l Bigma") that would be usable on BOTH my K1000SE film burner (in manual form) and on the K100D digital...
...but "for now", at least, I DO have the Vivitar to give me a capability of having a manual, equivalent-to-a-
105 to 315mm telephoto (or somethng CLOSE to that) lens, thanks to that
helpful "crop factor" parameter, when it's sitting on the K100D!
Yours Sincerely,
The PIPE!
