boyinthebush said:I am thinking of buying a pair of Bushenll H20 and am currently pondering the porro/roof debate. There's only £20 between them at Warehouse Express and my brain is stuck in a circle of "are the roofs better or worse for the extra £20"... has anyone used either of these or ideally both to compare?
Bill Atwood said:Well the Nikon is a good bino for the price, I have looked through both of these and the Nikon was noticeably inferior in every way.

I think you must be in their pay - is there really such a difference that its worth paying £440 for 'em? I've never looked through any expensive bins.
mike60 said:Re the roof vs porro design -
I find one great benefit in porro vs roof is the enormous depth of field of the porro, which leads to very little focusing and a much more natural 3d image, not to mention the quick response between seeing something with the naked eye, and having a focused bin view of the same.
Is this a general benefit of porro over roof, or an isolated case I have observed?
scampo said:I thought depth of field was a feature, not of roof- or porro-prisms, but of aperture (i.e. the effective size of the objective lens and its relationship to the eyepiece lens.
Doug Greenberg said:My argument here is that when you buy the very best binoculars you can possibly afford you get "returns" EVERY TIME you look at a bird! That's thousands and thousands and thousands of instances of definite benefit. Your binocs are your basic tool for birding; splurge there and then cut back on those things are aren't as fundamental.
As with many things in life, once you have used really good binocs, it's hard to go back to ones that aren't quite as good. Ignorance is bliss, etc.
Leif said:Porro prisms allow a greater degree of folding because a large part of the optical path is folded sideways. The Nikon 8x32 SE is quite wide! Therefore designers of roof prism binoculars are forced to use objectives with a small F ratio to get a compact form. This might also explain why roof prism binoculars esp. those in the 8x32 range seem to my eyes to have a lot of off-axis chromatic aberration.

I think the effect is even enhanced by the eyepiece (short objective -> short eyepiece), which is like a macro objective with an F ratio close to 1 (20/20). Close-up photographers surely know how lenses with large aperture behave with very short distances.
