Riflescope 101: Objective Diameter and Tube Size
Learn the fundamentals of riflescopes and how they work in our series of videos, Riflescope 101.
This video covers objective diameter and tube size; myths about clarity, what actually makes a difference in getting the brightest, widest image, and how to make sense of the options in riflescope dimensions provided to you.

bigger is better
What is the benifet of big tube scope sir?
Didn’t mention anything significant about tube diameter. But somehow it made it into the title of the video…
Tube diameter is a benefit for number of clicks available to zero or to adjust your scope.
Okay so what scope would pick up better light in low light conditions such as first or last light in a pine forest in central Louisiana? The crossfire II 3-9×50 or the copper head 4-12×44…. both are the same price range and assuming that shooting distances are irrelevant. I want to know which one I should buy. I will order one this week depending on the answer
if the objective lens has large diameter then it will provide small FOV and better brightness???????
Sure wish you made these products in the USA. I have to buy Leupold.
i see the Razor HD LH in my future!
Decent quality starts at about $1,000 for binoculars and rifle scopes. But you’ll never be sorry once you take them into the field. I had some huge Celestron 20×80 mm astronomical binoculars in cottage country side by side with a much smaller Zeiss 10 x 42 roof prism binos . After about 2 minutes with the Celestron, the image was so washed out, I did what most other Celestron owners do: I shoved them in the closet and never used it again On the other hand, I had a Zeiss Diavari 3-12 x 56 mm rifle scope. The sight picture with its "micro contrast" was fantastic. Plus with an exit
pupil bigger than your own pupil of 5 mm to 7 mm max. at dusk, even though your eye can’t use the surplus brightness, the target is acquired faster and more easily. Bottom line: Skip the junky optics from southeast Asia, spend the money and get good glass. You’ll never be sorry.
doesn’t larger tube size give you better elevation ?
I like a 30mm tube and a 44mm objective, a 1 inch tube is just too small and a 50mm objective is too big
Exit pupil !
But how do I know which objective I need for my location… I’m in the crossfire II / diamond back price range… I have a Remington 783 with the factory scope… I let 2 bucks walk this year because I couldn’t pick them up in my scope good enough to take a comfortable shot at about 250 yards… I got one clear as day at 400 yards with some Nikon binoculars but when they finally got close enough for me to consider shooting, I couldn’t make the image well enough… around 8:30 in the morning, slight fog and a shadow from the tree line covering half of the high line I was hunting…
Ceteris paribus; the larger objective, the brighter. it’s simply physics. You’re not helping at all.
