  1. I purchased the Walter Rx Leica-M eyepiece a few months ago. Everything I have to say about it is in the superlatives. It enables me to use my 21, 35, 50, 75 and 90mm M lenses with clarity and focus precision. I needed the correction for astigmatism as well as diopter. Miraculous device, especially with its rotation mechanism, since I often shoot in portrait format.
    If you have any reservations about purchasing the eyepiece, set them to rest – you will not be disappointed. Is eagle-eye vision and focus accuracy with your expensive Leica camera and lenses worth a few hundred dollars to you? I cannot imagine anyone saying “no”.
    I would now be lost without mine.

  2. Just to say that I am delighted with my eyepiece. I had found focusing on the M9 difficult and this gives me a crystal clear image in the viewfinder without having to wear my specs. I’ve noticed that people on the web are questioning whether and how it rotates. It’s a clever design and the lens rotates with gravity so this should not be a concern for anyone thinking of buying. Overall delighted.

  3. I recently got my first Leica, an M9-P, and after a while realised that my mild astigmatism (0.75) was a problem. I always used to photograph without glasses and with my SLR it never seemed to be an issue, esp. as I was using autofocus most of the time anyway.
    When focusing the Leica-M I encountered a difference when using glasses: I am sure every M-user is familiar with this “snap-in” feeling when the rangefinder image kind of glows up when focus is correct. Without glasses there was a tiny range in which I could not see a difference in the rangefinder image. Therefore I moved the focus ring a little back and forth everytime and never was confident about my focusing although the images usually turned out ok.
    Using glasses all the time never was an option for me, so I started searching for a solution. I came up with some ideas how it could work including the one with a decentered weight as the best idea actually, but without any plan how to get that done or who could produce it. So I was very happy to finally find out that the folks here already made this product and I did not hesitate to order one.

    ***Yesterday I got my eyepiece and it works great***

    Focusing with confidence becomes so easy in both landscape and portrait format.
    As promised the field of view does not change, thus the 28mm frame remains visible. A little side effect I appreciate is that the distance eye-camera increases a bit and therefore my cheak does not touch the monitor leaving marks anymore.
    After a few minutes I totally forgot about the eyepiece and just enjoyed the sharper rangefinder image I got.

    If and only if I had to find something negative I would mention the screw that holds the eyepiece in place. I had to turn it in pretty far and I am sure it leaves a little mark on the ring around the viewfinder. But this is really a minor issue.

    One might say the eyepiece is not cheap – I see it this way: We buy Leica because of it’s outstanding quality and are ready to pay a higher price for cameras, lenses and accessories. The eyepiece is completely in line with these quality demands, made of solid metal and with a finishing that totally blends in with the camera itself. After spending 6 grand on the M9-P another 350 (in EUR) for this hand and custom made enhancement that maximizes my Leica-experience were absolutely reasonable!

    Last not least I would like to mention the great customer support by Jean-Louis: He responded quickly and with details to every question I had and always kept me updated about the production and mailing.

    ***All in all a clear recommendation***

  4. When I was 40 I developed cataracts. During the time that the cataracts developed, I gave up photography. After the surgeries, and all the various treatments were complete, my vision started to settle down, and I started to shoot again. At this point I felt my vision was pretty good, and since I had always enjoyed rangefinders, I bought my first Leica. I have used the Leica Correction Lens and the Leica Viewfinder Magnifier, with minimal success. Basically, I simply wore my Glasses. The problems with glasses with rangefinder cameras are well known to all who wear glasses. You have a choice of seeing the frame-lines or see in focus, especially for lenses 35mm or wider. But even then, there is a sense of distance from the entire viewfinder experience.

    My vision is not bad, I can pass the drivers test and read a menu without glasses. But to focus accurately requires glasses. My right lens on my glasses is severely scratched from my M9. I have tried to train myself to focus without glasses, but the photo’s always came out soft. Even with glasses, if I focus with the wrong part of my lens, the image was out of focus (progressive lenses). So it was always a struggle with accurate focus. This is the “Lot” of poor vision with a rangefinder camera… So I thought…

    Over the last month or so I have been hearing about a new eyepiece, called WalterRX, which correct not just for the diopter, but for astigmatism. So after emailing a copy of my prescription for my shooting eye, I ordered one. Apparently production and sales are quite separated. Walter is the inventor and the optician in the background, and Jean-Louis Beek is the person is the person in charge of sales. Jean-Louis is wonderful to work with, and most accommodating to most any reasonable request. Jean-Louis Beek also runs another web business called while the WalterRX can be found at

    So after a several weeks, I received the eyepiece. There are two reasons it took so long. The first is that it takes time to create the custom lens, and the second is the business is out of South Africa, and I live in Central China. Installation is simple, after cleaning your viewfinder window, you slip the eyepiece over it. Tighten the screw slightly just so it grasps the rim of the viewfinder window without putting pressure on it, and your done.

    Using the eyepiece is also simple, just shoot. One caveat, don’t expect to have accurate vision while standing on your head while shooting. The special part of this eyepiece is the ability to keep the eyepiece tilted vertically no matter what position the camera is in. So as long as you stay vertical, your vision will be corrected accurately. The build quality is excellent, the bearings are smooth, and it rotates effortlessly.

    So the first day, I went out to my usual haunts shot the events that were my usual, except no glasses. This day I had my Summilux 75mm, and Summilux 35mm. I was shooting mostly portraits and street. The lens I started with was the 75mm, and I notices two things, first I could see the focus patch more clearly, and it took less time to find the sweet spot. The photos were sharp, better than I had seen with the 75mm Lux. I had always accepted it as a soft lens, but now I found out it was me…. Argh. The 35mm frame lines were well within the viewfinder window, and performed as always. The Summilux 35mm is a pretty accommodating lens.

    The second day, I took out my f/1 Noctilux and my 135mm Tele-Elmar. Both of these lenses can be focusing nightmares, in there own way. Again without glasses, to the usual haunts, and again the fine detail of the focusing patch were made clear. I was able to see with greater accuracy than even when I was wearing glasses. I think this due to the narrow focus patch of the progressive lenses.

    The third day, I took my Macro-Elmar 90mm with adapter to the park to shoot some flowers, primarily to see how the eyepiece would work with the goggles on the adapter. I found the vision clear, and focusing accurate. Each one of these test was done over several hours of shooting, not just a few minutes. I found my keeper rate greatly improved.

    The experience of using the WalterRX eyepiece, is much like using the Leica viewfinder magnifier, except there is no reduction in the viewing of the frame-lines, and of course no magnification. There is a very slight reduction in brightness, but is offset by the increased sharpness. Like using the Leica viewfinder magnifier, under certain circumstances there is a slight tendency to fog, but simply wiping off the eyepiece with a lens cloth, and your off and running.

    This eyepiece is expensive, but for glasses wearer, it’s a godsend. To help offset the cost, it’s designed so if your vision changes, it can be updated by your optician. It is simple and built to last. Yes, I sound like a fanboy… I know it, but if you struggle with vision issues, and find a simple and elegant solution you would too.

  5. I just have a slight astigmatism. The only reason I got glasses was to sharp focus with my Leica M9. I would take the glasses off to walk around and then put them on to focus the camera.

    I went out this past Sunday in the fog to shoot around the fishing fleet in New Bedford, MA. I had a great time and got some good shots. It wasn’t until I got home and looked at the sharp focused photos that I realized, I hadn’t used my glasses at all!

    Need I say more. Jean-Louis, you have a great product, thanks for thinking it up!

    Thanks, Sean

  6. Remarkable piece of engineering, My astigmatism drives me nuts since everything is just slightly out of focus, I don’t need a diopter correction and viewfinder magnifiers only magnify the astigmatism.

    Thanks Jean-Louis for such a wonderful product. It is a joy to use!
    Looking forward to using it on my M7, right now it’s amazing on my M9. No loss of FOV in the viewfinder and everything is crisp.!
