Fujinon FMT-SX 10x50

I was wondering if anyone else has gotten a pair of these and what your impressions were.

I once wrote a review of the FMTR (rubber-armored) version:
They are surely the best 10x50 astro binoculars on the market. As a general-purpose binocular, they are a bit heavy and, due to individual focuser, not so comfortable.

Watching birds at a stationary feeder seems to be the best use for them. For any other kind of bird watching, the individual eyepiece focus makes them less convenient. It is easier for me to deal with in the 7x50 because the depth of field is so immense, I rarely need to refocus. Although the depth of field in the 10x50 is excellent for a 10x binocular, it's still a 10x binocular so there is refocusing to be done.
One thing I notice is that the coatings appear very different from those on my 4 year old 7x50. The 7x50s are green in color, and the glass is as invisible as I have ever seen glass in a binocular. You really have to look hard for reflections, which are much more apparent to my eyes in the 10x50. The coatings on the 10x50 are a purple-violet, not at all green. The fact that they appear to reflect light more stongly may be misleading. In actual use of course it means nothing, the view is absolutely sharp and color neutral just like in the 7x50, only wider, bigger and unfortunately a bit bouncy. But that's how it has to be at higher magnification - they are a great pair of binos.

Is the useable ER on the 10X50 FMTR-SX actually 20mm? You mention that they are good for eyeglass wearers, and I know from the review of the 10X50 Pentax PIF that you wear glasses. Were you able to see the entire FOV in the 10X50 Fujinon w/ your glasses on? I ask for two reasons: (1) the eyecups look shorter than 20mm, and (2) because of a post I read in Birdforum by Henry Link that said the eyepiece lenses on 8X30 FMTR-SX are recessed by 7-8mm with the eyecups rolled down, leaving only about 9-10mm of useable eye relief with glasses instead of the listed 17mm (the minimum for my glasses/facial features). Could you see the entire FOV w/ the 8X30 FMTR-SX w/ glasses?
(see Henry's comments in context on the Webpage below).

I had a 6X30 FMTR-SX. The ER (listed as 20mm) was at least 17mm since I could see the entire FOV (8.3*) w/ my glasses. I had thought the the 8X30 would have at least 15mm useable ER if it used the same design as the 6X30.

Oops, no, I am not wearing glasses! But I noticed with the Fujinon 8x30 that its usable eye-relief was in fact much less than the claimed 17mm. I did not notice the same with the 10x50, and as much as I heard from others, they caused no problems for eye-glass wearers. Anyway, let's better wait for some opinions from people with glasses.
