what makes you think the tube diameter has the most to do wiht it, the glass, and coatings has the most to do with it, the tube dia has very little.

All things being equal, a 30mm tube "might" and I stress might be slightly brighter then a 1" tube.  This is also figuring that the guts are a true 30mm, which the Leupold is not.  Personally, I cannot tell a brightness difference between a quality 1" tube vs a 30mm from the same manufacturerer.

So in you guys opinion a Swarovski A-Line is just as bright as the PH and the Zeiss 1" VM/V are just as bright as the 30mm.  Interesting.  I don't agree or disagree since I haven't been able to compare them in the evening.

One more question.  Then why pay $500.00 more for the PH over the A-Line.

hmmm.... i wouldnt pay the extra money, unless i needed alot of adjustments, or sumthing, the 1" would work fine for me, and looks jsut as clear. also, some people like knowing that they spent a butt load of money on an optic, just so they can go bragging about the price.

guys...you can only fit a certain amount of light through a 1 inch tube...a 30mm tube (bigger tube)...alows more light to go through it so you get a brighter better low light situation scope...the size of the objective lens only allows you to have a bigger field of view...

The objective size only allows a bigger field of view????? NUTS

Lens size becomes more important the larger the magnification of the scope becomes. For a given objective lens size, doubling the power of a scope will halve the size of the picture seen by the viewer at the ocular lens. So yes you are correct in the statement that the objective allows for a larger F.O.V.

But this is not all it does. The LARGER the objective lens is, the more light the scope can transmit. More light means a brighter picture to be seen, This is very elementry optic stuff.

Field-of-view is a function of magnification and the focal lengths of the objective and eyepiece lenses. But remember this: The higher the magnification, the narrower the field-of-view. Field of view is determined by the ocular lenses in the eye piece.  Different factories and brands will vary in design and stats.  Decreasing the eye relief in a scope will widen the field of view.  So its a trade off one way or the other.

 

The light passes through the middle of the scope and most light your eye can perceive is 7mm.  A 30mm scope is not brighter than a 1" scope if all things are equal.  Read this post : 1" or 30mm.

 

A scope's brightness is determined by the exit pupil, lens quality and lens coatings.  Exit pupil is determined by the size of the objective lens divided by what power the scope is set on.
