Canon 10x42 IS WP - focus past infinity limit? (1 Viewer)

Greetings,

Can the Canon 10x42 IS WP accomodate about -6D of focus past infinity, so that it can be used without glasses?

Second question, how much eye relief does it have?

The Canon website states an eyerelief of 16 mm for the 10x42 IS WP.

Don't know about the focus past infinity.

I don't have exact information for the focus past infinity, but judging by the size of the diffraction pattern I can get with stars or distant light points when I focus the binocular to its limit past infinity, the Canon 10x42 IS L has considerably more than six diopters - my guess would be eight to ten. My reference for it is the Nikon 10x42 SE, which has about six and a half diopters +- on the right eyepiece, and if I focus the Nikon to its limit, I can just bring the right eyepiece to focus by twisting it to its limit. The Canon will focus well past the size of the diffraction pattern I can achieve with the Nikon, which in turn has considerably more focus travel than Leica models I have recently tested.

It would be useful if manufacturers would specify the focus limit for their binoculars, but they don't seem to consider it important enough.

My eyes are -6D, and when I tried a pair I had plenty of focus movement left at infinity - more than the 8x42 FL I ended up with.
