The IPD is 70mm because of the diameter of the lens. But, because of the extra-large eye-lenses and the excellent off-axis performance, there was no strain even for me of 62mm of the IPD. Your eye performance will be boosted up to twice, as if you became 12-feet of the Giant, that must be a thrilling experience.
I do not like the new eye-ring that consumes some of the eye-relief.
まず、このアイリングはアイレレーフを消費していて、改悪だと思った。
But, later found it was replaceable.
でも、簡単に取り外せることが分かった。
The field stop is as large as 47mm as before.
視野環径は以前の通り、47mm。スペック表示の85度は相変わらず??ですが、(正のアイピースとしては)2インチバレルで最大限の実視界を確保していることには間違いありません。(見かけ視界の上げ底表記はほぼ全メーカーがやっているので、仕方ないでしょう。)
低倍広角用として、非常に抜けの良い快適なアイピースだと私は思いますが、視野周辺までの点像等を最重視する方はまた違う選択肢があるかも知れません。ただ、双眼使用では、目幅によって外径の制約がありますし、このコンパクトな32mmは少なくともBINO用の低倍用アイピースとしてお勧めできると思っています。
Makers seem to be well aware that the more FOV display will promise the more sales.
It is very like actors or singers fudging on their height for their popularities. But I think they never fudge by inches, for fear of the fudge to be exposed, while there seems to be so many eye-pieces in the market as too much FOV displayed in the specs.
Local armwestling tournament, open category, was held last night in Tottori City. Most of the competitiors seemed to be near local, but several experts came all the way from Sakaiminato City,far west of Tottori Prefecture.(Tottori-City is located far east.)
I entered in the Beginner’s Section, but “Beginner” really didn’t mean a beginner to the letter. Most of them were actually advanced persons and very strong. I could only get two wins, each one win on right and left respectively, on the consolation match. I was a bit dissapointed with the result, but at the same time I told myself it was a small one step of my Armwrestling carrier.
After party was held at the snack bar,”South Orange”, in charter, and I was very happy to join the local members and to be introduced to the experts. Armwrestling table was also brought in the bar and we enjoyed practice matches over a glass of beer.
Not only they were so strong but also they were so nice. There was a common value of a kind of “Investigator” in all of us, and found all of us are very serious in improving ourselves.
