Jonathan Mac · 03-09-2020, 05:24 AM

It would be nice if this got into the hands of someone here to try it out and post some samples.

Anyway, M35 / 1.4 sold 6.
We all think this price is cheap.
Actual value should be over 1.5 million Japan yen.

I'm curious about that 35mm 1.4. Have you ever seen one? It seems at least as rare as this 20mm, despite being "mass-produced".

I'm hanging out for s/n 293001.... with all the losses on the share market $20k on a lens would just get lost in it all. I wonder if dcshooter would silver it for me......

So is the price 800,000 yen? That would be about $7500.00 USD?

The vignetting seems strong with this one, though. Is it just me, or have the photos been cropped to a different aspect ratio? So maybe vignetting could be even worse... but then this lens is probably more of a collector's item.

I will list this lens on ebay within a few days.
I hope that it will be in the hands of those who take good care of it.
If you have any questions, please ask me anything.

Please post a link when it's on e-bay. I don't have the funds for a lens like that but I'd be very interested to know how much it goes for and if it ends up with someone on the forum it would be very interesting to see how it performs.

I hope someone here gets it. Really it should be in a museum though.

D1N0 · 11-08-2021, 03:00 AM

I made an automated eBay search, but nothing turned up yet.

zbrueningsen · 01-02-2022, 07:48 PM

I saw a posting in January 2020 same deal - I have this lens but I know nothing about it. How in the world could you get this lens and know nothing about it?

What an amazing piece of history. Would be cool to see this!
