ggits Posted January 5, 2010 Share #1 Posted January 5, 2010 Advertisement (gone after registration) Focusing in f low values is not so well as I hoped for. My M9 or Lux 50 is not to blamed ! Further I would like to use my right eye (+2) and not my left eye (+/-0) so I figured out that if I buy a correction lenses on +3 and a viewfinder magnifier 1,4 I should end up with a balanced "sets of eye" and therefore be able to use my "bad right eye" for viewfinder and left eye open for "keep in contact". I only use Lux 50mm. Any recommendations ? Link to post Share on other sites More sharing options...
Advertisement Posted January 5, 2010 Posted January 5, 2010 Hi ggits, Take a look here M9, Summilux f1.4/50 & vievfinder 1.4. I'm sure you'll find what you were looking for!
jaapv Posted January 5, 2010 Share #2 Posted January 5, 2010 You would only need to buy a viewfinder diopter of -at a guess- + 1.5 or +1.0 to be perfect. Go to your optician and try it out with his trial lenses held between your eye and the viewfinder. Forget about the magnifier - it does not correct eye discrepancies - you would only be magnifying the unsharpness. Link to post Share on other sites More sharing options...
ggits Posted January 5, 2010 Author Share #3 Posted January 5, 2010 Hi Jaapv You would only need to buy a viewfinder diopter of -at a guess- + 1.5 or +1.0 to be perfect.

Forget about the magnifier - it does not correct eye discrepancies - you would only be magnifying the unsharpness. Thank you for the advise - I will go to my optician - and try it out. But anyhow will additional use of magnifier don't expand the focus area and therefore make a better/easier focus with e.g. 50mm. ? Link to post Share on other sites More sharing options...
jaapv Posted January 5, 2010 Share #4 Posted January 5, 2010 Not really - it helps some users with the longer lenses, like 90/2.0 or 135/3.4. With others, like me, the reduction in contrast and clarity makes it actually more difficult. I have a number of those lying about: 1.15. 1.25 and 1.35... A 50 Summilux should be easy to focus with a correctly compensated viewfinder. And the magnifier does not screw into the diopter, to use it you would have to unscrew the diopter, screw in the magnifier and screw a diopter into the magnifier - but a different one (0.5 stronger...)

andreas_thomsen Posted January 5, 2010 Share #6 Posted January 5, 2010 ooops why a stronger one with the magnifier??? i always use a +o,5 with and without the magnifier? cheers andy Link to post Share on other sites More sharing options...
jaapv Posted January 5, 2010 Share #7 Posted January 5, 2010 Advertisement (gone after registration) I found that on the 1.25x, and others noted the same. There was an optical explanation too, but I cannot reproduce it offhand. But if it works for you, it works Link to post Share on other sites More sharing options...
ggits Posted January 5, 2010 Author Share #8 Posted January 5, 2010 ooopswhy a stronger one with the magnifier??? i always use a +o,5 with and without the magnifier? cheers andy To balance my Eye. Left "correction +/-0" ; Right "need +2 in reading glasses" so correction M9 to balance Eye sets. Then inspired of Erwin Puts M9, part2 where he discuss improving focus adjustment using the magnifier 1.4 But I will tryout some corrections first and then ..... maybee Link to post Share on other sites More sharing options...
Guest mc_k Posted January 5, 2010 Share #9 Posted January 5, 2010 I would try a magnifier at some point. Megapearls / Japan Exposures sells one with a variable diopter. How helpful a magnifier will be probably varies with user and subject matter. I think a magnifier is just as useful with a 50mm as a longer focal length; it may help you focus more quickly, and by definition increases the accuracy of the rangefinder.

jaapv Posted January 5, 2010 Share #10 Posted January 5, 2010 I quite a agree. But it is no substitute to getting the basics in the rangefinder right - that should be done first Link to post Share on other sites More sharing options...

I only use Lux 50mm. Any recommendations ? Why the 1.4? I was under the impression that the 1.4 would lose the frame lines for the 50mm and works best with 75mm and up if you want to retain the frame lines. I thought the 1.25 was recommended for 50mm and up but not sure if this is true. Link to post Share on other sites More sharing options...
