Actually I have tried them...the Genesis.... But I was more talking about how I haven't seen any in the field.....
Just a guess but I think you might see more of them when birding in Japan.
Japanese companies nowadays are notoriously bad in marketing their stuff outside of Japan. I just need to look at the serial number of my Fujinon HC to comfirm that as it is number 505 that was made (if the numbers simply count up).
Often some models aren't even offered outside the country.
I never see anyone using binos but there are no popular birding spots around here -- I think birding is just not a thing here, even though there are 2 bird watching towers nearby. The only optical instrument I saw being used there was a camera with a huge lense. But I have not much experience in birding anyway, just a fan of binos in general.
It seems they went out of fashion. When I was a kid, everybody had "a good bino" in the family. My Dad had a Japanese Tasco 10x50. my one grandad a Steiner 10x50E, my other grandpa a Hensoldt 6x24, one of my aunts uses an old Hensoldt Dialyt 8x56 to this day -- awesome bino. One of my friends has a Swaro 10x42, I think it is an EL. Another friend has a Steiner 8x30. Those are the only binos I saw people using lately.
Currently I couldn't even find a store apart from hunting stores where one might buy a bino locally. 20 years ago opticians carried Zeiss and Swaro, but not anymore. Not even a measly Nikon Action EX in any store.
