Monitoring a well-known world market since a while. There is a certain craze there - nearly every lens which can't be properly identified becomes a "Tomioka" - made lens. Or maybe "Komine". Than the seller sets an unreasonable price and waiting for the Godot to his item being sold.
Nevermind that even the (unjusitfiedly) famous 1.2 Tomioka seem to be a pretty lousy lens, hugely over-rated and I believe, no comparison to Minolta 58mm or Nikon 55mm or many Canon lens (FL 1.2 to FD SSC 1.2) which can be easily converted to EOS mount. Just got my third Fujinon 1.2, all under 100 Euro. With the new MFT <--> Fuji AX adapter time to "downgrade" these great Fujinons to Tommy Miau Oka cat's miau and sell for few Megabucks.
But hey, every Miranda, Mamiya, Mamma Mia lens now is Tommy Miau lens, so I am going to have a big company. I know, there was a secred collaboration between Tomioka and KMZ... and every 58mm Helios is a Tomioka. I did read the secret files in the basement of KMZ. And Тётя Маша (aunt Mary) has a Tomioka plant in her огород (veggie garden) growing, so $$$$$ is the limit.
That's the common Yashica lens, sure, made at Tomioka (seriously). I have several and was seriously thinking, they are Okay lens worth maybe 20-50 Bucks. Now I know, I have a gold mine. You look at a proper tree - there should be a Tomioka growing on some branches, look carefully!
I have that, too. Was thinking an OK lens for 50 Buckeros Americanos. Not anymore. Tomioka revolutionarios came, that's worth at least 500 Bucks after Tomioka revolution.
It's THAT real, that now after the Tomioka revolution a common M42 lens can be easily adapted to Nikon "F" mount. 1-2-3 and done, no hard work because it's Tomioka.
