For someone that doesn't need extreme low-light performance, and mostly uses a scope for the flat 2-dimensional focus and crosshair, do you think they would miss the extra objective lens size dropping from a 40 or 42 mm down to 32?

I ask because I'm looking at low power scopes, such as 1.5-5 or 2-8 variables, but you can only get those low magnifications with smaller 32 mm objective lenses. How much and what am I losing by dropping in objective lens size?

in my observations as long as you stay with quality optics you are loosing nothing going from 40 to a 32 or 33. when its first or last light turn her down to three and you wont see a difference from 40 to 33 or I don't as long as im using good optics

Honestly, I would like to have the scope on 1.5 or 2 magnification most of the time. The vast majority of my shots are at less than 60 yards, with the average being about 35. I just need a scope because my old eyes can't see open sights.

For that kind of hunting situation i don't think you can go wrong with a leupold 2-7x33 or something similar .

What's the field of view difference ?

I don't like below 40mm

The special ops guys use red dots at those short
distances

you want a scope that equals the maximum amount of light your pupil can accept to the exit pupil of the scope. For young eyes, 7mm is the maximum exit pupil the human eye can fully utilize. For someone OLD, like you, exit pupil decreases, probably down to 5 or 6 mm \:\) .

you calculate a scope's exit pupil by dividing the objective mm by the power. For example, a 4x 32mm scope has an exit pupil of 8mm (even more light transmitted than your eye can utilize).

At your age, a 32mm objective scope would allow maximum light transfer with any power LESS than 5x.

OR, for your basic 2x7 x 36mm scope, it would allow full light transfer to your retina in low light conditions up to around 5-6x, but you there would be a noticeable loss of brightness at 7x in low light conditions.

Not so!

Weaver 2-10x38 Classic V Rifle Scope

Zeiss 1.2-5x36 Conquest DL 30mm Rifle Scope

Zeiss 2-8x42 Conquest DL 30mm Rifle Scope

Meopta 1.5-6x42 MeoStar R1 30mm Rifle Scope

Schmidt & Bender 1.5-6x42 Zenith 30mm Riflescope

Swarovski 1.7-10x42 Z6 30mm Riflescope

That said, I have multiple scopes with 32mm or 35mm objectives and they work well enough in low light at reasonable ranges. They are obviously not optimal for hunting big, wide open spaces at dusk or dawn.

Nitrex TR One 1.5-5x32
Minox ZA5 1.5-8x32
Vortex Viper 2-7x32
Burris Fullfield II 2-7x35
Zeiss Conquest 4x32 fixed
