SL2 diopter settings?

[T25UFO]

Advertisement (gone after registration)

I have just ordered a new SL2 and downloaded both the Quick Start Guide and the full Camera Manual.  The Quick Start Guide says the diopter range is -4 to +2 and the Manual says it's +4 to -2.  

Can anyone confirm which is correct?  I currently use +1.5 on my M cameras.

Thanks.

Well, both options cover your setting

True . . . but my eyes are not getting any better and I may need something stronger on the M.  If I go to +2 on the M what is the true value after taking account of the standard M viewfinder setting?  I always get confused with this.

Also, it does seem a bit odd that no one in Leica has picked up an obvious print error.

On the SL2 camera you just see markings, no numbers to describe them. But in the end only the correction counts ...   and it should be enough for you.   By the way, how is it set on a M ? I have a M246 and did not know I could set that at all.

I assumed it is -4 to +2, but maybe I am wrong. Usually (in most cameras) the negative range is bigger.

Whatever else, it is certainly less critical on the SL2 than on a rangefinder.

There's no setting on the M, you just have to buy a correction lens that screws into the viewfinder.  The diopter for the M240/246 series doesn't fit the M10 series.  Each diopter costs around £150 in the UK, so it gets expensive when your eyes deteriorate😳.   Easier and cheaper to turn a little wheel.

I checked the printed manual and found the detailed sketch diagram (right side of page 40) shows -4 to +2 whilst the wordings under the heading DIOPTER SETTINGS on the left indicated +4 to -2.  

So the Quick Start Guide is correct.

My personal conclusion.

 

Cheers.

the M10 has already an .7 correction . So you are correcting on top of that. The Leica SL2 does not have that, I have to correct so much less what makes sense.

If age takes you past Leica limit it is time to wear glasses.

M viewfinders have a minus .5 diopter built in.

Opposite sequence for me. I have always worn glasses when using an M to correct for astigmatism and distance, without a separate diopter. But I now require both glasses and a +.5 diopter, which is common with aging eyes.

Well my eyes have aged much worse than the rest of me (says me), I find the diopter adjustment on the CL to be better for me personally than that of the SL2 which I can manage with.  For reading glasses I need +3.  CL offers +4 to -4 whereas SL2 +2 to -4.  I have +3 diopter on my M.

Yes, but that is to optimize for the 2 m virtual distance of the RF patch, and calculated for eyes that need no correction. As soon as you have to correct for the actual non-perfect eye it gets complicated, as the optician measures for either 50 cm or "infinity"

Exactly.  And one reason why the SL2 VF is different, as someone noted.
