I'm sure this has been covered before,but i'm wondering what trade offs should be expected in choosing a 32mm objective binoculars over larger
42mm binoculars.
the well known advantages of a well chosen 8x32 should be a wider field of view often combined with a closer focus distance,though in many cases there will be less usefull eyerelief.depth of focus can also be less than desired in a compact binocular,however i'm specifically thinking about resolution and sharpness at distant object/birds.
the situation is that i'm currently choosing new binoculars,the leica ultravid
8x42 is my present first choice,but the trinovids are also very nice..and cheaper.
the 8x42 trinovid is a beast though,because I need to close the barrels almost as far as they will go (close set eyes) there is no room for me to curl my thumb under the left barrel,this effect makes them feel like a rubberised house brick!,so if I chose a trinovid I think i'd prefer the smaller 8x32,if I were to choose the ultravid the 8x42 model would be my first choice,so i'm weighing the pro's and cons of both.
what I would like to know is if there is a difference in sharpness and resolution
between the 8x42 and 8x32 bn trinovids?,the difference in depth of focus,close focus,exit pupil and field of view are well noted elsewhere on this forum.
your thoughts welcomed
