Thanks Stanbo, I finally managed to get to the Canon Asia website.They've also got their knickers in a twist.They state that the real field of view is 6°. And the apparent field of view 55.3° (wide), which is I suppose using the iso-standard.But they also state that the field of view at 1000 yards (feet) is 344.5.One of these statements is wrong as 344.5 feet is about 6.5°.They also say 2 AA alkaline batteries or two AA nickel metal hydride batteries. The 10×30 used to also specify lithium AA batteries?The weight is given as 21.16 ounces, but 22.2 ounces with a 10×30 Mark one, in both cases without batteries.I suspect that something is wrong here also.The measurements also seem to be a bit odd with the two binoculars. I will have another look at this.I suppose that the people who write this stuff, don't actually weigh the binoculars or measure the field of view.Also the photographs of the new and old 10×30 look the same, but they state that the photograph is for illustration purposes only.I suspect that in fact the changes to the 10×30 are not that great, but one can only hope that perhaps the field of view is 6.5° with excellent performance.We will have to wait and see.</blockquote>
