Who posted that?

Neither of mine are in storage mode and both get used regularly - usually with a wide angle on one and something more macro oriented on the other. It avoids changing from K mount to m42 as well since one has an adapter and the other doesn't.

OW! OW! I want it (but I already have two!

Nowhere have you mentioned the superb bokeh that these vintage lenses produce. Lovely - which is why I use them!

I can't speak for the 200mm (ain't got one) but the T6-2 converter is excellent. I put one on Ebay recently and it was ignored! The F AF converter is an absolute steal at that price. I use mine regularly and would not part with it. There is a bit of a learning curve but once you get the hang of it .... pair it with an A series 50mm macro, just for example!!

There are a couple of them here link

Well, that got people talking didn't it?

The 80 - 320 is a very capable lens. I wouldn't part with mine.

We are the traditional camera users. We are useless as far as a modern manufacturer is concerned. Today's audience wants instant results without fiddling of any sort and will amass thousands of images to our hundreds in any given period. We demand quality. They demand quantity and they certainly don't want to change lenses in the middle of doing it. We are happy(?) to lug a K1 around - and even a tripod to support it with our K mount 400 - 600mm zoom mirror lens or a 50mm macro on a bellows. They want it to fit in their designer jeans back pocket and be capable of doing all those things "whip it out quick and shove it back". They want their faces in front of everything; we want to capture subtle nuances of (to them) boring things. Sorry folks. we are yesterday's business models and we won't make corporate postage stamp money against the megabucks demanded by today's big businesses. Once upon a time, you saw single lenses being offered on Ebay. Today, with the writing on the wall, you see piles of them (literally) and piles of old cameras too. Stack em up and get shut of them while you can. It's a gloomy prospect but I tell myself, "act your age (75) and accept what you can't change."

#7 really does the biz for me.
