[Paddlewise] Cameras - Lenses and Waterproof

<In my experience(qualification: I have no interest in looking at


photograph of a resolution chart, especially with a magnifying glass),


lens quality has little bearing on the sharpness of an image. The


anchoring of the camera by the photographer and the mechanics of the


equipment has a greater impact.>





 I can agree that shaking the camera body certainly effects the quality of the
image.  It will negate the effect of the best lens.  Leaving aside that type
of external factor, it is the lens that primarily dictates the sharpness of
the photograph.  


    A sharp photo requires a good lens first, and good film secondly.  The
lens receives and transmits the image to the film.  All irregularities in the
lens show up on the image that arrives at the film.  Therefore, image
sharpness degrades with the amount of lens irregularities.  


    Most brand name films are just dandy.  Because of film advances, I would
also agree that even the high speed (eg, ASA 400) are fine for most uses.


    The camera body, is however, nearly irrelevant to the sharpness.  What was
said in the 30's is just as true today.  "Give me a good lens and film, and I
will give you a good picture from a cigar box."
