I spent some time today comparing them to my Nikons.
For a comparison sake, the benchmark(s) were 10x Nikon LX L (HG predecessor) and EDG. In my Geovid-R example:
When viewing close objects, the depth of field was a bit more restrictive on the Geovids than Nikons, yet at range 300m+ I didn’t notice a significant disparity between the LX Ls and Leicas. The EDG was a bit better…
CA was acceptable - not as good as the EDGs, but not bad at all.
Edge to edge on my Geovids was pretty good - compatible to the LX L - the Leicas , however, are noticeably more sensitive to correct eye relief. Once the eyecups were set, the view was actually quite good.
Of note, my example appears to have some dust between the objective lens and the focusing lens on the left barrel… I wasn’t able to notice it while glassing, but I’m going to have Leica correct it.
LRF performance is solid on my example.
More to follow once I have more time behind the glass.
