This week I bought a Tamron Adaptall 2 2x telencoverter 01F, which is in almost like new condition for less than £30. Luckily I had a spare Nikon AIS mount so I sdidn't have spend another £30 on one.
Trouble is, I'm not too keen on it even though it works as it should. I suppose part of me is a little disappointed at the lack of brightness in my FM2n's viewfinder, even with the f2.5 of all my fixed length tamron lenses. I know I lose two stops to it, but the microprism is unusable as it doesn't "shimmer" at any time and the split rangefinder only works with my eye exactly dead centre on it otherwise it blacks out. On the plus side the ground glass does seem to be more useable, partly because of the bigger image. I may not keep and just go for a Tamron adaptall 2 1.4x converter instead.
I think I was "spoiled" a bit by my Mamiya 2x converter for my M645 1000S because the image stays bright enough to focus easily. I was originally surprised at how bright the screen is when I first got the camera, as I'd owned an ETRSi some years ago and I needed a Beattie Intenscreen to get it to a decent "indoor" brightness.
I also bought 7 12 exp kodak verichrome pan 126 cartridges for my SL126. I now have about 23 Kodak films (some Colour) for it, and even less space in my fridge for food.
