If I was younger and my eye pupil was larger I accept your argument.In fairness I did think my 7x42s gave a brighter image than my previous 8x32s in the gloom but not when compared to my latest Swaro 8x32s.Easier eye placement is often used as an argument for larger exit pupils which I think is important for small boat sailors in choppy waters, rarely for normal birdwatching. I should add I use 8x25s on non birding holidays with no eye placement problems. The important factor is to know your binoculars and get used to them.I should also add choose them wisely.I sometimes use my Zeiss 7x42 Dialyts as a symbol of my longevity as a birdwatcher at RSPB Honey Pot sites but my ancient appearance probably does that more effectively.</blockquote>
