A 26mm aperture and 160mm focal length, if that is what it is, is not fast.
In fact it comes within even Conrady standards maybe.
I was using my 2016 Canon 8x25 IS last night and unfortunately it is a lemon. Made in Japan.
I was looking at Jupiter.
The IS is jittery. There is bad and strange false colour, lots of it, and maybe astigmatism or the IS part is not properly aligned. Jupiter is cross shaped with blue and red ends at 90 degrees to each other. Most peculiar. I don't think it is my eyes.
The 2014 sample is brilliant.
So one really has to try any optics one buys, as bad examples turn up.
Generally I have had very good Canon IS results over almost 20 years. But it is only fair to report this very poor example.
