Leica Eyesight Diopter Lens Problems


Leica Frog

I'd like to ask Leica users or customers about your eyesight problems when focusing with your Leica M body. I've used the Leica M for many years since M6 M7 M8 M9 & M240 and got the problems all times with Leica eyesight diopter lens that can't adjustable to my sight and it's very hard to find the one that's proper to my sight.

To solve this problem, I think it's very simple and not difficult for Leica to do for their customers but it looks like "an unserious or unnecessary problem" for them, instead of the other camera brands, they'd made the built-in adjustable eyesight for their customers for many years.

Advanced thanks for your comments.

I understand that it might be possible to have a prescription lens made, that would fit into a screw in dioptre eye piece but this is an example of one of the better known makers of an aftermarket product, which can accommodate a more complex prescription:

 

Walter RX Leica M rangefinder astigmatism rotating eyepiece | Leica M9 M9-P astigmatism rotating eyepiece diopter correction lens, fits rangefinder M8 digital M7 M6 M5 M4 M3 M2 leitz analog cameras.

 

...also if you search for posts by one of the forum moderators, JaapV, you will see that he has commented on this subject a number of times.

 

Hope this helps

Thank you for your advice sincerely.

I've ever used the correction lens like this before, it includes magnifier too, the brand is "Match Technical" but I lost it (2 pieces) during my trips and camera carrying on my neck, screw of the correction lens loosed gradually when camera body touched with my clothes, last time at Frederick Square, Shopping Center in Copenhagen. So I wonder why Leica Manufacturer don't think about this simple built-in adjustable eye-correction for their loyal customers, anyone agree with me?

One more problem is about the Leica correction lens eyepiece, there is no +2.5 correction lens that's suitable for my eyesight too.

You have to try them you know. My prescription for presbyopia is +3.5 but if I wear +1.25 contact and use a +1.5 diopter in the M9 it's just about perfect for range finding. I use mono vision contacts so it's 3.5 in the left eye, 1.25 in the right. Nothing is simple it seems

Having worn glasses "full-time" for about 57 years, it still seems simplest to me to correct my vision that way. I've used cameras for most of that time and never found glasses a problem - certainly less a problem to keep them on than to take them off and use a "corrected" camera. Viewfinders on modern (1960+) cameras seem fine for glasses, and even my 1935 III is manageable. However, I'll admit the pinhole eyepiece of a Canon IVSB is barely usable with glasses.

Same experience as TomB above….just keep my glasses on, especially given astigmatism and my light sensitivity that requires sun protection (sunglasses) in daylight. Fortunately my prescription allows for both distance viewing as well as seeing the focus patch (virtual distance 2m). I'd much rather do this than taking glasses on and off with a diopter, and considering that I don't like contact lenses.

 

Eyes are personal…even folks with similar 'numbers' have different comfort levels and preferences. Trying is the only way to know. And hope that things don't deteriorate.

 

Lots more discussion on this issue via search box.

The problem seems to be that it is very difficult to build a compact adjustable diopter for a rangefinder system.

In the meantime the solution is simple: Go to your optician and, using his try-out lenses find the diopter strength that you need. I it is within the range that Leica offers, just pick the nearest value.

If your eyes need a stronger correction have your optician replace the lens of a Leica screw-in. He will probably have to cut it by hand, as modern machines don’t go down to 10 mm.

If the above is impossible due to astigmatism or otherwise send your prescription to   http://walterrxeyepiece.com and he will make a suitable diopter for you.
