        I have a real difficult time with this  Wright, Now that I have 
been using my  Nikon D100 (digital SLR)  for just about two years, and have 
pushed every lens I own in front of the sensor.......... I cannot believe 
that any zoom fixed lens is going to come close to using Macro lenses at f 
stops smaller than 8 for macro photography.   I change lenses all the time 
and shoot a great many images under all condition, I have not seen a dust 
problem,  Sent the camera for an annual cleaning and everything was 
fine.  I'll tell you what is different, I had a lens, that had a small 
speck inside the lens itself, probably an internal finish flake    ... I 
used the lens on my regular bodies for years and never notice, on a digital 
I kept seeing a cloudy spot on every image in the same location ..  the 
digital sensor picked up the dust as it read through the 
lens.............   I had to have the lens opened and cleaned  .. Never 
showed up on any non digital image.

        I know that the lens not made specifically for digital have some 
problems wide open, and that the 1.5 factor bothers some people who love 
wide angle, but for fish, there is nothing better than a 105mm lens acting 
like a 150mm ...  still 1:1 reproduction capability and increased distance 
from subject..   I just love it. ! - I now have a 300mm macro lens capable 
of 1:1 ..  Now that's an amazing lens

        If you look at the Pro's at any sporting event today....99% of 
them are shooting digital SLR's with BIG lenses from their film bodies on 
them............  they make a living on their ability to capture quality 
images and have all just about completely converted to digital.

        Now don't get me wrong, I still love color slides, the definition 
and quality is still fantastic, and the ability to scan them at extremely 
high resolution makes them more versatile.  But I "gotta tell you" a 6 
megapixel image in tif format is one hell of a image size, and at ISO below 
400 makes for some amazing reproduction.
