Early in the New Year, Jörg-Peter Rau wrote to suggest a series of articles on non-Leica cameras which used the M-mount. I readily agreed although it seemed like a lot of work at the time.
As it turned out, I was right. It was a great work for J-P, and I am still amazed at how he juggled all those cameras (and lenses), managing to test seemingly every permutation. I certainly learned a lot about equipment I had barely given thought to in the past. The M-files became a constant companion during the first four months of 2021, a fortnightly cycle of preparation, proofing and publishing.

The series represents a monumental investment in time and effort, and I am sure it will become a popular internet resource for anyone interested in the history of the M-mount. All this was only possible thanks to a number of helping hands who were generous with loans. Enthusiasts like David Babsky provided some cameras and lenses, says Jörg-Peter.
I am sure all readers of Macfilos join with me in thanking Jörg-Peter for all the insight and expert analysis he brought to this venture. Of course, the M Files are not complete despite all the effort that we put into it. Jörg-Peter has said that he will add a few more episodes about some popular, easy-to-find and interesting Zeiss and Voigtländer lenses within the next few months.
He might also be tempted to dive deeper into the Konica M mount system, most notably the 35/2 and the exotic 21-35 dual range lens. So if a Macfilos reader has such gear and is willing to support the project, I am happy to put them in touch with Jörg-Peter. He told me he also considers acquiring some selected items if reasonably priced.
If you are new to The M-Files, here are all the links to the Macfilos articles in English and the German versions published on Messsucherwelt.com.

Our donations link is now back in action
Apologies to all readers who have tried to donate in the past four weeks and found the message, “this site can’t accept donations”. PayPal changed the rules and didn’t tell us, so we had no idea anything was wrong. We have now sorted this out. If you wish to make a small donation, we will be genuinely grateful. We are a non-commercial site, funded personally by the editorial team. Any assistance is appreciated.
I shouldn’t say this ..not with the post-Brexit extortionate import/export charges between Germany and the UK – thanks, Alexander Boris de Pfeffel Johnson.. but I do happen to have here “..the exotic 21-35 dual range lens..” if J-P wants to try it. (It was, supposedly, the inspiration for the Leica 28-50-35mm (in that order) mini-zoom, and the Leica 16-18-21mm (in that order) very wide mini-zoom.)
I don’t find there’s all that much difference between 21mm and 35mm (I don’t use 35mm anyway), and a 21-45mm would have been much more useful, I think ..but what do I know?
Anyway, it’s yours, J-P, if you’d like to borrow it. (It makes a very good 21mm, anyway!)
Cheers,
David.
