1.
The OM-4Ti viewfinder magnification of 0.84x is given at -0.5 dioptres in the
specifications for some reason, but I haven't any info on whether this is the
'standard' setting.
2.
The brochure says the variation on the OM-4Ti diopre adjustment is from
approx +1.0 to -3.0 dioptres. My OM-4Ti black has 22 positions, ie 21
intervals; that's about 5 per dioptre then. But I'm not sure which 'end' of
the scale is which!
Kind regards,
