If that's not enough, the long range guys are using 34mm tubes... And larger as well. After using 34mm tubed scopes, looking through a 1” or 30mm tube seems like looking through a straw Can you attribute that to the 34mm tube per se? I guess so. Try it by looking at a few mounted on rifles, side by side. I seriously doubt that. In a riflescope everything does through the erector tube inside the main tube and then the eyepiece. The erector tubes are pretty much the same diameter, around 19-20mm. An inch tube is 25.2mm in diameter, with a wall thickness of 1-2mm, you get some adjustment range. A 30mm tube usually has the same wall thickeness as the inch tube so you have 4.8mm more edjustment range. Many 34mm tubes have thicker walls, maybe up to 4mm thick. So they don't have more adjustment range than the 30mm tubes, but they are far more sturdy and stable in the sun and against shocks. I would think there may be 34mm tubes than trade wall thickness for extra adjustment range, but the further you move away from the center of the first focal plane, you may encounter some IQ degradation. The FOV is a function of the size of the eyepiece, among other things; the size of the main tube by itself, doesn't enter into it. When you compare riflescopes, get all the specs for it. I looked at the specs for the Leupold VX-freedom series and their 1 inch tubes riflescopes have good FOV specs, right in line with the 30mm tubes of the same magnification. No soup for you. (To coin a phrase.)

DT2- the 30mm can be lightweight but if you want longer range get a 1" tube. The smaller 30 MM tube gets you less elevation clicks, the 1" gives you more elevation clicks and the apprearence of more light transmission, but you pay for it in weight. Seems like the difference is what distance are you planning to shoot and how much weight do you want to carry. Good luck! Ive read this several times, and im still in need of an expert explanation of it.

The explanation is he's got everything backwards.

He’s got the right understanding, just 180 degrees opposite.

Right, and they have a greater range of adjustment, up to 100 MOA, so the erector rube is not any larger, it just has more room in which to move. The erector tube dictates the amount of light coming to the eyepiece.
