Originally posted by unixrevolution From what I've seen on eBay, M42 Takumars and Spotmatics are all over the map right now. I'm curious about this myself, as I ran across a Takumar 1.4/50 at a pawn shop, and want to know how much I should ask for it. (Don't worry, I already had a 1.4 takumar, so it's not as though I'm getting rid of the only one I had.)
According to eBay's "What's it worth?" Dialog, the 1.4 is worth 79.73 on average, with a price range of $0.01-$149.00.
The 28mm f/3.5 is worth $47.57, with a maximum price of $129.
The 135mm f/3.5 is worth 43.35, with a maximum price of $89.
Of course, how much your lenses are worth depends on their condition and where you try to sell them.
They have always been all over the map. However, there are at least 3 different versions of the Super Tak 28mm f3.5 lens. The first one has 6/7 formula with 58mm filter threads and f3.5-22 and the 2nd one is the same except it is f3.5-16. The 3rd one is 7/7 with 49mm filter threads and f3.5-16. There's a similar thing with the Super Tak 135mm f3.5 with a 4/5 and 4/4 version. There may be other subtle variations on top of that.
There are 3 versions of the Super Tak 50mm f1.4 as well not counting variations. The earliest has a 7/8 formula and the latter 2 have 6/7. The best way to tell them apart is with the Asahi part number on the A-M switch 358, 378 or 37801 in order). There are also Honeywell part numbers.
879 on the oldest and blank on the newer ones.
That said, those price are actually what I observe and these lenses are on a list I keep up with to some degree.
Edit: The Asahi part number on the A-M switch for the Super Tak 28mm f3.5 in order are 348, blank, 43871 and the Honeywell numbers are blank, 741 and 7081. As you can see, the blank ones cause a problem since they correspond to different models in the Asahi/Honeywell scheme.
The Asahi part number on the A-M switch for the 4/5 Super Tak 135mm f3.5 is 354 and the 4/4 version is 43541 and the honeywell numbers 743 for the 4/5 and blank on the 4/4.
