Magnifying eye piece or EVF?

I really would like to improve my focus on the 75mm & 90mm lenses, the way I see it there are two choices, use the 1.4x magnifying eye piece or use the EVF but I'm unsure which would be the better option.

 

I love focusing using the rangefinder so i'm guessing the first option but will they fit the M10's eyepiece ok? or do you need the thread adaptor? 

 

I"m unsure of the EVF, the only one I've ever got on with was the one on the Sony A7RM3 which is 3.69 mp, the Leica EVF seems to be a little smaller than the Fuji XT-1 and I didn't get on with that at all, it just wouldn't adjust to how I needed it.

Have you first made sure that your eyes are optimally corrected for the VF.... for any astigmatism, diopter strength, etc. I have no trouble with the M10 using 28-75 (or 90mm, currently not owned) with the RF, my glasses and a +.5 diopter.

 

The best way to know is to actually try the options.... rent demo or buy. And there’s also the option to mount the lenses on an SL or CL to take advantage of their superior EVFs.

Both choices can provide benefit, and both have drawbacks. Adding optics to an M VF tends to reduce contrast and has other effects, but the larger image can help focus. I sometimes use the 020 EVF with a 90, and with focus mag you can focus quite exactly. However, my base Sony A7 is much better in response, etc. - although accuracy is about equal. The EVF of course adds shutter delay as live view has to close-open-close the shutter for an axposure.

I find I can focus a 90 about as well with the M10 RF as with the EVF, depending on subject detail being RF friendly. At 135 I can tell the EVF has an edge in exact focus.

Then follow Jeff's advice.

You should be able to focus lenses up to 90 mm without any difficulty or aid.

I have the Summilux f1.4/50 ASPH and the Summarit f2.4/90 (rather recently bought) and I find both as easy (or difficult, still learning:-) to focus, even though my eyes are not perfect at all.  I liked the focus handle on the Summilux, but the Summarit doesn't have that feature and now I wished both had none (for consistency).  When I bought the Summarit, I also tried the Summicron APO f2/90mm ASPH, which I found more difficult to focus, probably because the focusing turn is larger.

 

I have considered a correction lens on the eyepiece of the viewfinder but as my eyes keep changing slightly I'll try later again.  I even considered the specially made correction lens (incl the needed astigmatism correction, can't remember the supplier now) but I think this only works taking landscape pictures, or fiddling with the correction lens when taking portrait, which is too much trouble for me.  All in all, I seem still to become better at focusing with the plain RF.  I once tried the EVF on my M10, and both I and the shopkeeper were appalled by its lousy screen image.

Just to answer directly - you will need the thread adaptor (24001) for the M10, and I occasionally use the 1.4 with longer lenses as I find the bulk of the EVF just too much and only use it with long R lenses.  I also have a diopter fitted as I find wearing my glasses to shoot a pain.

Thanks for all your help guy's, I think I'll wait until after my eye test and just use my distance glasses until then rather than my pair for computer use, might go for a custom diopter then once I know for certain what I need.

Tell your optician that the virtual distance to the M focus patch is 2m. Take your camera along and place the trial diopters (any good optician should have a set) in front of the VF to determine optimal viewing.

 

I wear glasses to correct for distance and astigmatism, then add a +.5 diopter.

 

No need for a magnifier, which can also reduce contrast.

I think your computer glasses should be far better than your distance ones.

If you have astigmatism, you need a Walter Eyepiece:

He does an M10 model as well, AFAIK

I use my regular glasses for distance and astigmatism correction. A small diopter correction does the rest. Fortunately my normal prescription allows me to see both the focus patch as well as distant objects. My computer/museum glasses are far less effective. And a Walter eyepiece would mean that I’d have to take my glasses off and on.

 

Each person is different, with eye issues and with comfort levels regarding various solutions. Only way to know is to try.... along with proper diagnosis.

Couldn't agree more. The only way to know is trying.
