Overall
Owner since: more than 10 years

Cons: Bit on the heavy side compared to present day high end bins; also CA in very bright light sometimes but no bother really.
Pros: Just like seeing with your own eyes- no roll or flatness of image when still or panning. Colours are very true, very forgiving focus point like 7x42BN and great depth of field. It's our house binocular and has never let us down; Leica recently replaced the whole casing on warranty so just like new on return to us- fab.
Summary: Worth every penny and mint examples still sell for same price as new 14 years ago- unsurprisingly. If you're OK with just a little more weight they'll make watching nature such a pleasure.

Cons: Chromatic abberation is not totally supressed (slight in centre, high at the very edge - last 15% FOV), Not as bright and white as SwaroVision Problematic accessories
Pros: Stars are point like (same superb result as Swarovision), Resolution is nearly on level of Swarovision Wide FOV (130m/1km), Good edge sharpness, large sweetspot (85%), Super robustness, lockable diopter Good contrast, HDC coating Internal blackening and glare resistance due to light traps is better than swaro, what I rate as excellent. Could be used for self-defence :-)
Summary: Silver make slight yellowish picture but in some situations this flaw make image much enjoyable. Built like a tank so it is very durable, diopter setting of leica is best on market (you can make Individual Focussing binocular :-)) , obsoleted model make finding accessories problematic, only few shops have it. Super mechanics and very good optics make that binocular challenging to many newer models of various manufacturers. At price which I paid for it, is very very good. At last trip I use it as hazelnut-cracker so good is aircraft grade aluminium body for nature watcher :-). In terms of optical quality I compared Leica Trinovid BN to much more costly EL SwaroVision 8,5x42, which is optic etalon IMHO. Trino BN is very good backup for it in term of optic, and in term of durability, I carry it on hardest trips than swaro. Only flaw of these binos is CA.
