Are these replacing the Canon 8x25 IS binocular? They don't look much smaller.
See 8x25 here:
I noticed this cutaway view of the 8x20. It shows a much simpler objective design compared to the 32mm models and the glass cover plate has been dropped. It's not completely clear, but possibly the whole objective/IS lens assembly moves back and forth for focusing. A quick look at the actual binocular would reveal what moves and what doesn't. At the eyepiece end the field flattener is now a singlet instead of a doublet, presumably because that's all that's needed for the modest 50º apparent field width.
I wonder if they use the same rubber armour? They were a lot of complaints about the armour "melting" on the 10x30 IS. They are a little pricey for a 20mm. The FOV's are pretty narrow with the 8x being 6.6 degree's and the 10x being 5.3 degree's. You are paying a premium in price and performance to get the compact size when the standard 10x30 IS II has a 6.0 degree FOV and still is pretty light at 20 oz. and sells for $500.00. I do like how the objective lenses seem to be recessed quite a bit which would be good for stray light and protection for the lenses.
In the video one can see that the IS activation button is click-on-stays-on, which is great as one does not need to hold the finger on the button.
What happens if you push the button before the 5 minutes is up, does it reset and give you 5 minutes from then?
It's got two buttons--one for each mode--IS and Powered IS. If you have an IS mode on and you push the same button again it will turn off all IS. If you push the other IS mode it will switch to that mode and the five minute timer starts over.
