Bino wise.
I sent this to a mate the other day that was looking at a new set of Binos.
Just thought it may help some members select a new set.
I picked max 42mm objective for reasonable size / weight ( lighter ones are around 20 oz ) be careful some of the 42 are up to 26oz.
Magnification wise I the picked 8x over 10 x in the 42mm as the 8 have a better twilight factor (more available light to the eye in low light) than the 10x.
Objective lens diameter (42mm) divided by magnification = twilight factor the higher the number the better
ie
10x 42 = 4.2
8x 42 = 5.25
So to get the same twilight factor in a 10x you would need a objective of 52.5mm so 10x50mm in round terms - but have a look at the weight and size of a set of 10x50 = a lot bulkier and heavier.
Hence I went 8x 42
More magnification like 10x would be handy and in full light in 42 mm you loss nothing and gain 2x mag. but in low light you will not pick up some detail. But also 10 and up do get hard to hold steadier free hand.
An other thing is higher mag = smaller field of view
7x 32 are good option also, small compact & light, great field of view ( close quarter work) twilight better than the 10x42 but not as good as 8x42.
In general I think if you want them to find game in close and at distance then 7 & 8 are the go. But if you want to assess trophy animals at ranges you will meed the 10x and up. ( spotting scope territory really)
Relatively light and compact - you are more likely to have them on you and then use them more.
Use Google on and binos you want, and you will find reviews on them all over the net - don't forget bird watcher sites as well as hunting.
I settled on a pair of Pentax 8x43 DCF SP as all the reviews had them only a fraction behind top Euro makes at only 1/2 the price. If $ was not a limiting factor I would have gone the top line Steiner 8x42mm
I would try and stick to roof prism, not pro prism - more reliable & ergonomic and I think compact as well.
Just my process of selection, hope it may help.
