Teleconverter I can't to afford to buy a 400mm lens and I shoot a lot of film on sporting events, especially baseball. Is there a compatible telecoverter for a Tamron 28-300mm f/3/5-6/3 ld aspherical with an Elan 7? (Would prefer a 1.4) - Two self-proclaimed camera experts told me I'm out of luck...can't be. Help... Thanks!!!

Vee, You're out of luck. Even if you could find a compatible teleconverter, the effective aperture would be too low to autofocus. A 1.4 would stop you down one stop, giving you an effective aperture of about f/9. A lens like that would be near impossible to hand hold, and would need a shutter speed to slow to capture fast moving objects. Sorry buddy, your camera expert friends are right.
