A camera lens with an eyepiece added is unlikely to be much use for anything other than the moon IMO, if you really want to go this route a 1000mm mirror lens is probably the best bet. This site has some good amateur Saturn and Jupiter images taken with various telescopes http://www.weatherman.com/. Bear in mind that you will not see images as clear or contrasty as these by eye. I have never yet seen the Great Red Spot on Jupiter despite staring at the planet for hours on end through my 6". Mail me off list if I can be of further help.
