"Light gathering power" is specified by the widest f-stop,
not the lens front diameter (which often is larger for a
longer FL lens of the same speed, but not necessarily
so...). And, the filter-thread diameter tells you only
the mounting-thread size for accessories - in both cases
above, the lens front element size is considerably smaller
than the mounting thread size... The two lenses above
have about the same f-stop at the widest zoom setting
(f1.7 for the TRV11, f1.8 for the PC100 - making the
PC100.TRV20 lens, if anything, slightly slower (admitting
less light...).

This is true for all camcorders - they all range between
about 42mm and 48mm FL (in 35mm still-camera terms) at
the zoom short end. BTW, the PC100/PC110/TRV20, having an image
that is a bit sharper than the TRV11/PC5/PC9 image, accepts
WA converters with a generally more acceptable level of
image quality.
