I have a pair of Nikon Action EX 10x50's that are real nice in low light, however when I hunt in a climbing stand for woods hunting (as opposed to large fields and cutdowns), they are pretty much in the way....read BIG and bulky.  I need a more compact pair of binocs with lower magnification but I don't want to give up low light capability.  Roofs would be the natural choice for size but (A) they are more expensive and (B) they are usually not as bright as their porro counterparts.  I compared a buddys 8x42 Bushnell Legend (roof) and I was surprised that they were significantly less bright than my Nikon even when considering the difference in magnification.  How would the Legend porro 8x42 compare to the Nikon Action EX 8x40 when it comes to brightness and resolution?  The Legend is supposed to be fully MC and the Nikon is just MC(I think).  FWIW, we can legally hunt up to 1 hour after sunset, so low light performance is important.

Thanks.

Personally I think if you want the low light capability of a 50mm, in something smaller, you are going to have to step up to a more expensive binocular.

For example, Minox BD 8x44 BP porro prism binocular runs around $370 on the internet.

Exit Pupil 5.5mm, Eye Relief 18.5mm, light transmission of 94.5%, (less light lost than a roof prism).

I am sure those are good binocs, but at this time of year they are out of my price range.  I don't really want to spend more than about $150.  In optics I know you get what you pay for but one day I compared my Nikon's to a friends pair of 10x50  Swarovski porro's at near dark.  There was a difference but it was not that great.  There was a larger delta between my Nikon and the aforementioned Legend roofs, than with my Nikon and the Swarovski.

I need low light performance more than I need compact size.  I need something that is fairly compact, but I have to have the ability to distinguish antlers in the woods  30-45 min after sunset.

OK, then, 8x36 Monarchs. Fairly light and still pretty bright, cost around 200-250. I always was impressed by the brightness in Monarchs, all but the 10x36 which is getting a little on the dim side. I have 10x42s and I use them in woods for birds. Though I use 8x40 Actions too.

I appreciate your thoughts and the time that you have taken to respond.  What do you think of the 8x40 Actions?  When I need them the most is when the birds have long gone to roost.  I believe that I need at least a 5mm exit pupil and good quality fully MC glass.  I am not bird watching, I am hunting under very low light conditions.  Let me re-state, I need glass that is at least as good at light transmission as the 10x50 Action Extreme......but in a smaller package with a bit less magnification.  Even low quality 8x26 binoculars will work for 10-15 min. after sunset but that is not what I need.  For a while I had been leaning toward the Legend 8x42 roofs, that is until I compared them with the 10x50 Nikon.  I liked their size, design and their resolution in good light.  They just don't do the deed at dark.  From what I have seen the roofs just don't have the light transmission that the porros have, that is, until you get into the high dollar stuff.  Edge to edge sharpness is a great feature to be desired but it is NOT as important to me as light transmission.

Light transmission is why I suggested the Minox porro prism binoculars in the first place.

It is my honest opinion that once you get into the Minox it will fill the gap and you won't be needing another binocular for quite some time.

I have had the Nikon Action binocular in another magnification,for a different application,and I sold them after only three months,as they were optically unsatisfactory to me.

The Nikon Action Extreme is somewhat better than the Action but I do not believe there is "enough" of a difference to do what you are expecting from them.

Going from a 50mm to a 40mm will give you a smaller "sweet spot" in the center of your viewing image, and the edge distortion in the smaller 40mm might be distracting,or unpleasant enough,to disappoint you.

Waiting awhile and saving up the extra money for the Minox BD 8x44 BP porro prism will bring much more satisfaction in the long run and alot less mediocrity.

The Actions will do in most light for me, but what you may really need is some high end 7x42s with the low light conditions. I do not have these, so can't really recommend a brand. They will cost up from $900, $1500 for the Zeiss. The Minox may work for cheaper, but they have no 7x.

Nikon Ocean Pro 7x50 can be had for $250, but they weigh 38 oz!
