    There are many threads about which focal length to purchase, but what are factors in deciding how big of a lens to get? Something like this is impressive because it's 77mm http://tinyurl.com/mbftw6 , but what does it do better than something like this http://tinyurl.com/867pku that is 52mm?

    One of the reasons I bought my D80 with the 18-135 was that I liked the look of the 67mm lens vs the smaller 18-55. I also like looking at media guys do their job with those fat lenses. Have you ever purchased X length lens and then had buyer's remorse because it wasn't large enough?

    like penis size, the bigger the better. Also, notice how the white Canon lenses are shorter than their black counterparts on the Nikon side. Thats no coincidence :o

    Personally, all else equal smaller the diameter the better for me. Lighter > heavier.

    Bigger lenses do make non-photographers take you more seriously. They are happier to part with their money when you use big lenses to take their pictures.

    I don't see anything about lens diameter in any of these lens threads. If all things are equal then I want to look like I know what I am doing. Nothing less than 67mm for me!

    i find that im more comfortable with lens that has its weight spread out VS all in front.
    diameter doesnt matter to me

    It's not how big your lens is, it's how you use it :hsugh:

    seems like you've already fallen into the belief that bigger is better

    :dunno:

    refrain from buying based on side...base it on focal length and aperture speed

    For land based photography I'll agree that front lens diameter has nearly no value.

    However for astrophotography diameter is king. For a pretty extreme comparison take the Canon 50 F1.8 and the 28-135 F3.5-5.6. I have them both and have tested them on the same deep space objects and the 28-135's larger lens brings in much more light than the 50mm's tiny little thing canon calls a lens. My own tests were done with the 28-135 in both 28mm and 135mm shots. The 50 struggles to even produce a nice milkyway shot compared to the 28-135 as it just can't pick up the fainter stars and dust clouds.

    personally a 77mm front filter thread is a plus because all my MRC B+W ND/CPL filters will fit, and those get a bit pricey. i have used a heliopan 52>77mm adapter, and it worked fine, just looked a bit goofy.
