I wrote up a description of the Ricoh version of the Vivitar 2xmftc (hah!) on my blog because I was unable to find much info regarding this thinger before getting it.

The short-short version... I'm pretty sure it's the Vivitar rebranded, and it has the spring/ball style of "Ricoh pin" and seems to present no risk of getting stuck on my K200D (though it was a bit nerve racking PROVING that it wouldn't stick!). EDIT: See below for a warning that I may have just been lucky so far with the sticking issue... And I have been so far unable to get really satisfying photos from it (though the blog post lists a litany of reasons why this is probably my fault rather than that of the TC.)

I figured I'd post here so that others who come across one might be able to find out a bit about it.

I have one of these and it certainly got stuck on my K10D.
Took me ages to get it off and I then proceeded to remove the pin.
Since then it has been fine, although I hardly use it and have just won a Vivitar PK/A version on Ebay for $50.

Wow, that's bad news to hear it go stuck. Did it work for a while and then one day get stuck or did it stick the first time you used it?

Worked for a while and then one day it stuck.

Ok, looks like surgery is in order before I use this again. Thanks for the warning!

Mine is Teleplus one, PK/A version, most likely made by Kenko. It also had the "ricoh pin". It worked fine on DS, never got stuck, but it got stuck on K10D the first time I used it. luckly with a little force I was able to take it out. Now the pin is removed.

Interesting this pin; I purchased the K10D just over a year ago to replace my Ricoh XR-M & immediatly on returning home, fitted the three lens I had (Ricoh, Tokina & Tamron) with no problem; lucky me as I had no knowledge of a problem.

The pin seems to "land" on top of a screw & I'm wondering if the that screw is turned slightly in a different direction during manufacture changes the orientation enough to cause, not cause, the problem. I wonder if a metalic epoxy could be used to smooth out that area?

Its actually not a bad little converter.

50mm F1/7, closest I can get is this.





With the converter ....





That's the top flower.

I am selling mine soon as I should hopefully be getting my Vivitar PK/A version any time now.

Great find! I've seen 'em go for as high as $130. I'm quite happy with mine, although I haven't had much time to play around with it. I keep meaning to...
