M8 135 apo performance

of course the missing 135 frame in the M8's viewfinder makes the use of the 135 apo a bit tricky, but, nonetheless, I found focusing quite easy with my 1,25 magnifier and my recently purchased diopter; I can only advise anybody to put their glasses down and get the correct diopter: it really helps; both examples shot with the 135 apo and 160 ASA; first example 1/30sec handheld (!), second example using a tripod and a cable release

The diopter is confusing to me . i wear reading glasses and that would be in the commercial readers a 200 but my ability to see distance is good. I use the Magnifier and things look good but i bet with a diopter it maybe better but i have no idea what to get to try it. Sorry went OT

Your distance glasses- which you don't have- strength minus 0.5 .So you would have to have your eyes measured for distance.

There is nothing wrong with that 135 apo....

Guy, I use reading glasses too. I've just bought a correction lens with the same diopter as my reading glasses - +2 - I was aware that the viewfinder has a built in diopter of -0.5 but figured that someone with perfect eyesight would have to compensate for this, so I would too :-). The lens has made a huge difference, I certainly wouldn't want to go back to not using it.

 

The worst thing about the correction lens is the price - £61 from Ffordes in the UK. It's very small and thin, so doesn't add noticeable depth to the eyepiece.

If you only need reading glasses, as do most people after age 40 with previous 20/20 eyesight, then simply get the same diopter strength that you use for your drug store glasses - +2.0. It is very thin and screws onto the 1.25 magnifier. That is what I have and it works perfectly, and of course you don't need your glasses any more. In fact, you can't use them at all or it will look worse than it does without them.

i don't get it. why would you use your reading glasses to focus with a rf? you'll be looking at oblects at least 70 cm away from you.

 

i just tried with my varifocus glasses and i get a definitely blurred image when i look trough the bottom part that contans the 2 diopter correction...

If you wear reading glasses that correct for 20/20 vision due to age deterioration of the lens of the eye, you will need a plus diopter to correct for it. Without glasses, the rangefinder or any other camera will show a blurred scene just as in trying to read a book at 15 or 20 inches from your nose. You correct this problem on many other cameras by turning the built in diopter corrector. Setting it to +2 for example renders it useless for someone with normal close vision as it now becomes blurry for them. If you have reading glasses as you say and when you look through the viewfinder it is blurry, then you have a problem. The only time it will be blurry is if there is already a diopter on the camera and you look through it with your glasses on. Why do you think they make diopter lenses for cameras? A +2 diopter corrective lens on the camera focuses at 1/2 meter, exactly as do reading glasses of +2 strength. They are identical.
