Disclaimer: I can only write this brief summary for myself.
As I'm the only one who has my eyes.
First point as stated above and by other people
Eye glass wearers need not apply, look for a different binocular.
Nowhere near enough eye relief for spectacle users!
I took these out this morning for a couple of hours to the local burn and river { Tyne }
Really nice optics, very sharp, very large field of view for a budget range.
Nice smooth focus wheel, no trouble what so ever, will be easy to use with gloves.
A bright white/grey sky, so looked at dark branches against this background.
To MY eyes, no CA at all.
This only eludes to me, you may see, you may not.
I'm not going to mention anything about slight colour casts as this is purely subjective.
As an example, the star Vega: to my eyes brilliant white, to some a greenish cast, to others a blueish cast.
Lovely to use in MY hands.
The right dioptre ring does feel weak so I carefully set the dioptre and set it in place and I won't touch that again.
The eyecups were a bit loose to the touch but at this price this is nitpicking.
As I don't wear glasses when observing I was pleasantly surprised to find I could use these at every position of eye cup.
Even when fully retracted!
I place eyecups up against the bone of eye sockets.
Again your bone structure may differ but I didn't have a single blackout!
I do have Alpha glass binoculars so I'm not coming to this pair from a cheap department store model.
For the money £200 UK { October 2023 } they are fantastic optically.
A real pleasure to use if you don't wear glasses and you don't treat them rough.
Steve.
