hoppyman Posted July 26, 2010 Share #21 Posted July 26, 2010 Advertisement (gone after registration) Can you define what you mean by an objective test? (let's all ignore the optical pun for the purpose of the discussion:)) I have the 1.25x and the 1.4x. You can actually stack these things for a real telescopic tunnel experience of 1.19x on the M9 and an eye watering 1.59x on the M3! My lenses are recently Solms calibrated too. What are you proposing to test? Happy to contribute if you have something in mind. Rangefinder alignment accuracy? I could only see that being tested validly from a large sample and controlled conditions Light transmission to the eye? My subjective opinion is that the 1.25x is helpful with my 50 f/1.4& 75 f/2 wide open in lower light and in close. I can see the difference in clarity vs. no eyepiece magnifier but that is offset by the benefit of the larger image of the rangefinder patch for me. No practical benefit on framing. Very un-scientifically, two other users here who were concerned regarding focus accuracy were surprised when the magnifier was added to a tripod mounted, pre-focused camera. That was also my experience. You just pick up errors that are less apparent without it. Certainly it's not essential, but it can be a useful tool. I only use mine occasionally. I find the 1.4x version to be less useful and comfortable in practice. YEMV (Your Eyesight May Vary) Has anyone tried to check the effectiveness of magnifiers in an objective way? Does anyone use more than 1.4X additional magnification? Link to post Share on other sites More sharing options...

Guest mc_k Posted July 28, 2010 Share #22 Posted July 28, 2010 Can you define what you mean by an objective test? I meant something more than just shooting with a magnifier and getting an impression. I was thinking of some kind of low-contrast eye chart or some such. To compare a variety of magnifiers, I just focused on a mannequin head in dim light. And I went by the ease of focusing, not results. And of course I also went out and shot with the different magnifiers a lot. I found a medium magnifier was more useful to me than a larger or smaller magnifier. Link to post Share on other sites More sharing options...
hoppyman Posted July 28, 2010 Share #23 Posted July 28, 2010 OK, understood, I agree. I find the 1.25x to be more comfortable (eye relief and clarity) and useful for me than the 1.4x and both a little less clear than the bare finder for me. I find both demonstrably more accurate for fine alignment. Link to post Share on other sites More sharing options...

biglouis Posted July 28, 2010 Share #25 Posted July 28, 2010 Pity that Leica doesn't make a 1:1 rangefinder. Hard to return to film when my Epsons fall apart. There's a thought.... Link to post Share on other sites More sharing options...
sblutter Posted July 28, 2010 Share #26 Posted July 28, 2010 I 2nd the 1.25x magnifier on M9 - bought on Ebay from Hong Kong, is just fine - nice price and build. I miss the 0.85 of my M6 Link to post Share on other sites More sharing options...

woebau Posted January 8, 2015 Share #28 Posted January 8, 2015 A late reply: I am using my magnifier 1.4 on my M9 nearly all the time - it is ideal for 75mm lenses (the Summicron 75 is my very favorite lens), and it is a must for 135mm. On the other hand, when shooting 21mm, there is no need to take it off. Shortly, I like the magnifier a lot - it makes my M9 the most similar possible to my M3. I have no problem with clarity. Just for the 35mm, I take i off - sometimes, because otherwise with the 1.4 magnifier you would shoot what you see in the "entire" (visible) viewfinder and maybe a little bit more. https://www.flickr.com/photos/woebau/ Link to post Share on other sites More sharing options...
jaapv Posted January 8, 2015 Share #29 Posted January 8, 2015 I never use magnifiers - and I have a few lying around. I find that I can focus better without.... Including the 135 APO. It is a very personal thing. Link to post Share on other sites More sharing options...
