BINOCULAR Specifications
for Birding the best sizes are -
8x30 - small lightweight , porro prism normally-- General birding, bird tables etc
8x 32 - small lightweight , normally roof prism- General birding-
8x 40 - general use bins- porro or roof prism - good field of view - at home in woodland, rain forest etc
8x 42 - probably the birder bins of choice atm- roof prism - good field of view - at home in woodland, rain forest etc
7x 42 - bright image, huge field of view and deep depth of field, roof prism- excellent in rain forest and on dull winter days etc.
10 x32 - small and powerful but not great in rain forests, leafy woodland or at dusk. Narrow field of view.
10 x42 - Popular size , big image , normally roof prism- great for open country birding, not so good in rain forest and woodland.
10 x50. - Big and heavy - bright image,bulky but optically excellent roof prism, also available as porro.
As a guide, divide the second number by the first- the higher the figure, the better the light gathering power of the bins. Anything below 4 is probably not bright enough for birding in all conditions.

Hi-
REMEMBER- a good 2nd hand pair of bins is often better than a new pair of not so well made at the same price

For would be buyers; as is always recommended ..... do try before you buy binoculars. I visited a dedicated optics store and tested out a pair of Swarovski's EL 8.5 x 42 but couldn't get on with them at all so I opted for Leica Ultravid 8 x 42 which I love. Other half preferred the Swarovski's so it's down to the right binoculars for the right person ! Never buy directly online as you do need to hold them in your hands, feel the weight, look at the field of view given and see if they suit you as an individual !

Birding is for everyone no matter how good or bad we are at it,enjoy it while you can
Sorry to hear you have macular degeneration/Crohns Pete; my late aunt also had MD where her central vision was affected and she had to give up driving. I had Lasik treatment over 20 years ago which freed me from glasses for a good 18 years so will investigate my options again as I'm missing so many birds and relying on Mike to spot them !! Just that everything is harder to arrange with the pandemic and main concern is keeping a careful watch on Mike to ensure the oral cancer stays at bay, fingers crossed for all those suffering from health problems at the moment including yourself Pete.
