Actually, you have to ask yourself another question first: Why should I repair my historical camera at all? Well, I'm not primarily a collector, I also want to use my old cameras. That's the only way I can understand the essence of a camera. So I have to at least repair them, but it would be...

Thank you for your feedback.

That's a very interesting point. I'll look into it. The exponent of 1.2 seems to take into account the fact that, in practice, the system resolution is slightly better than one would expect based on the simple formula. This is interesting because it would result in lower values for the purely...

It wouldn't leave me alone. My comparison of the Minox A, Mamiya Super 16, and Edixa 16 also focused on the lenses. Unfortunately, I had to work with estimated values for the resolution because no published values were available (except for my own for the Minox A). Now I've taken the...

In the meantime, I have continued comparing the three subminiature cameras. Some of the results surprised me. Here you can find my thoughts on the Minox challengers Mamiya super 16 and Edixa 16. Now it's time to look at the lenses and exposure systems...

Minox may be legendary, but it's not the be-all and end-all when it comes to subminiature cameras. I took a closer look at two alternatives that are certainly not to be outdone: What happens when three of the 20th century’s most brilliant engineering minds tackle the same challenge? I have...

:D

Actually, I just wanted to give a tip about the Minox frame counter. It's about a mistake I always made when reading the frame number without realizing it. But once I started thinking about it, more and more questions came up. First, here's the initial question. What number does this frame...

The ultimate test of whether a camera repair has been successful is to expose a roll of film. Only then can you assess whether shutter, escapement, lens adjustment, and film transport are working correctly. We have therefore taken test photos and posted them online. Take a look at the pictures...

The VEF Minox Riga is a true icon of subminiature photography. It is not just a camera; it is a testament to the technology of the 1930s. But as with any old masterpiece, time and use can take their toll. When a legendary piece of machinery reaches a certain age, the question is not whether to...

Thank you very much for all the tips! I will follow up and see what I can find.

Thanks for explaining that! Now I finally understand where those reviews come from that say you should overexpose rather than underexpose film. So it's all down to marketing. Of course, film manufacturers wanted to advertise their films as fast as possible. Do you know the source of the...

Many people who use analog cameras are concerned about whether the shutter speeds are correct and or how they can be adjusted. These are legitimate questions, especially if, like me, you enjoy working with these cameras. But is this question also relevant in practical terms? How important is...

Having Minox colour films developed is a complicated and time-consuming undertaking. Since I practically only take colour photographs, I have come up with a method that solves this problem. The same procedure can also be used for other small film formats, so it is not limited to Minox. If you...

That's very interesting! The Mamiya 16 is a really great design. It's bigger than the Minox, but the negative format is also larger. The ingenious thing about its design is, as you say, its simplicity. This not only makes it easier to manufacture but also makes it much easier to maintain and...
