RNG35

I saw in this forum a user saying he has a 70-300 Canon lens. So I wrote that in Google and I found this link on Amazon about this lens :

Canon EF 70-300mm f/4-5.6 IS USM Lens for Canon EOS SLR Cameras
$544.63

http://www.amazon.com/Canon-70-300mm-4- ... B0007Y794O

Is this lens good for RNG adapter ? Because it has also the SLR in the title and I heard you can use SLR lenses. If this lens is no good, then how can I identify a good 35 lens ? Because I always hear : I have this 50mm Canon lens , and I have this Nikkon lens... but there a thousands Nikkon an Canon lenses out there. How do I know which one is compatible ?

Sebastian, I used this exact lens for a shoot on Saturday. Click on the link below and click "Indistrial Bride". The 70-300 was used in the shots of them walking off in the distance at the end and also when they are kissing at the end. I used a Nikon 50mm for the rest of the shoot.
