Wrong, resolution is a "classical optics" concept that has been around for hundreds of years long before computer graphics. The larger the objective lense, the better resolution. With all things being equal as far as lense quality, and optics to air coatings, a larger lense will resolve better. Thats the reason even digitial cameras, the wider the objective, the more you can resolve. You can take a 7.1MPix picture of a wide angle object (say a mountain), and if you do this with a 10mm lense, and zoom in, you can't see the details. So your wasting your time buying a large resolution camera with a small objective. Best you can do is maybe 2meg. But with a fine camera with 50mm or larger lense, this is were it comes into play.

Alot of folks believe the only reason to buy a 52mm scope is wider field of view, but there's alot more to it. A person witha large diameter objective at the same power can view say points of a deer at longer distances than with same power scope with smaller objective. Its just simple physics. Issac Newton is one of the pioneers of this. Its hard for commercial dealers to explain this to customers, and they put on these gimicks like light gathering.

If you ever get into telescopes, you will the serious hobbiest having some serious lenses or collimators.
