I just picked up one of these on a whim. I won't get it for a few days. Anybody familiar with it? It seems like an m42 helical but has a teleconverter as well? _________________ photos are moments frozen in time |

Got it. A 2X TC with two screw on extension tunes marked 2.5X and 3X. I can't remember if I ever tried it. Unsure if extenders go before or after the TC. Redlections look like 4-element, but maybe only 2, they are close together difficult to count. No helical. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

Oh well. It was cheap and I can always use the m42 extension tubes. The 2x well....we'll see. Spiratone stuff is a bit of grab back some quite good others....not so much. _________________ photos are moments frozen in time |

I first got into photography in the early 1980s, by which time Spiratone ads were the photo equivalent to JC Whitney ads for cars. I spent lots of time scouring the Spiratone listings, but the Varxtender was an accessory that I never paid any attention to. It seems rather clunky in operation, but I imagine it works ok for what it does.
Here's an eBay ad for one:

Here's another listing from Google books -- an article from a 1970 edition of Popular Mechanics which mentions the 2x Varxender, and which includes a brief description as to how it works.
