Message: <blockquote data-quote="Gilmore Girl" data-source="post: 3469687" data-attributes="member: 106744">See my last post about the batteries ... I corrected a couple of things.I use the specs as a guide and I know from using bins for a long time what I can use and can't use, what I prefer and don't prefer.  The lighter smaller IS bins have either small EP and/or short ER. I wear glasses and need sufficient ER and find small EP annoying. I can't use 13.5mm ER which is what I see on the 8x25.Also FOV looks to be real narrow.  The bigger IS bins dimensions and weight specs are enough to make me avoid them. The battery issue is yet another problem for me. I'm just not liking the idea of using batteries for a bino when I'm used to no batteries.  Maybe a rechargeable bino (just plug the bino in)with very long lasting battery life like an iPhone could be nice improvement.Just my preference ... if you're happy with an IS bin please continue to enjoy.If I ever get the opportunity I will try an IS bino and see how I like it.I apologize to the OP for going off topic.</blockquote>
