Re: [APML] Telephoto vs. Teleconverter

["Eric Royer" <eroyer@club-internet.fr>]

Hello,
One more thing to consider is that with the 300 f4.5, you can use both
lenses at the same time (if you have 2 camera bodies).
With this trick you can shoot 2 photos at the same time which allows you
different framing or using different film (color or B&W)...
If often do that. Flexure won't be a problem because the focal length is
relatively small.
With 2 cameras at once you double the number of pics you can take in one
night !
