Scope obj size
- Thread starter bongo
- Start date
At any given magnification a larger objective lense will give you a brighter image.
For dawn and dusk work this can be an advantage.
For many years I used a 6X42 but in later life mainly used a 3-12 X 56 or similar which was more versatile.

It is not quite as straight forward as saying the bigger objective lens allows more light to pass through as the magnification also plays a part on the light received.
The following article explains it quite well. In theory a 6x42 scope actually allows the same light to transmit to the eye as an 8x56 if you follow this theory. However, by increasing the magnification within reason, the object being viewed in the image is closer so may 'appear' more visible.

Hi Munty,
Can you explain how" you will shoot more with one this size" given that the exit pupil size of most adults, at best, is around 7. Please feel free to enlighten me.
Cheers,
Fatty.
When i say adult, i mean not a youngster i.e. over 30 not over 18.

One other point I meant to make...
Hi magnification scopes are handy for taking longer than normal shots. I personally would only be taking them when the light is good so I can see the target clearly. Is there a need therefore for a high mag scope coupled with a large objective lens??????

Yeah , you will have more field of view on a large objective lens at higher mag .

When I started I was advised by a very experienced stalker that 6x42 was all you needed for deer stalking.
Of course knowing everything I went for 3-12x56, illuminated reticle blah blah blah
What does that 3-12 sit on for all my deer stalking? 6x
Does the 56mm obj lens give me extra low light capability? Yes....enough to see outside the legal 1hr after dusk before dawn window.
Do I ever use the higher mag......yep...when I'm foxing, using a lamp, so the bigger obj lens makes no difference.
So Gary M(my very experienced stalker)....I'm learning and 6x42 really is enough for the vast majority of stalking deer

out to 800 meters you mean. ohhh your naughty
anything above x42 is just extra weight and raises your line of sight and in turn diminishes your shooting due to poor cheek weld. anything within normal ethical shot distance can be taken with a 6x which is also good for woodland stalking.......getit
Stock configuration varies as does facial shape and neck length.
If the comb of your rifle is too low `comb raisers` are easily sourced and fitted.
I have have had vision problems for many years and found the 3-12 X 56 a better option for my needs

I've tried pretty much every option available from 6 x 42 and variables up to x25mag and a 56mm objective.
Now that I've got all of that out of my system, I now have a Swaro 3-12 x 50 illuminated on one stalking rifle and a swar 2-12 x 50 illuminated on the other!
I use down to x2/3 in close woodland and x12 is useful for longer range stuff, as well as on the range. I like a fine reticle generally, but it is almost impossible to see at low light which is why I chose illuminated. Optimum magnification with light gathering up to about x7 mag. (7 x 7 = 49 which is almost 50!).
I shot a lot of deer with a 6 x 42 fixed power, but I've shot a lot more with the set ups I have now and have no desire to change anything.
You could do a lot worse than a 3-12 x 50 and it should cover all your needs.
