Yes! These 100/2.8s are very nice indeed. I had one of these practically glued onto my camera for a good while until I found an RE Auto-Topcor 100mm f/2.8 to compare to it. I recently found out that they are at least extremely similar if not optically identical , with the Topcor having better build quality and different coatings (Topcor's build is more refined and has a slight IQ advantage as a result).

This particular Vivitar can be found under several(!) different brand names with a few variations in build. Here is a thread I started on this breed of Vivitar 100mm f/2.8:

Spoiler: I still don't know for sure what manufacturer churned these out.

Still in the post-apocalyptic ghetto mood, so here is a second one from the series, though I much prefer the cold one posted above earlier.

Last month I shared an image of a northern mesquite lizard (Sceloporus grammicus microlepidotus). I commented that around here they are known as lagartijas de árbol or tree lizards, and a few days ago I found out why.

I was looking out of one of my apartment windows and saw this little fellow perhaps a meter away on the tree that grows just outside. My window is 10 meters above the ground.

Note the blue belly; this is a male.

Regards,

Alan
