Thanks for all the replies. Sounds like I have to do a little more thinking before I decide. Even though the gear is new in box, it's still a lot of $$ to spend on old and discontinued gear.
Daveandiputra: Yes, if I buy this kit I plan on using the lenses for video on my dSLR also. It would be a win win situation if I could use the quality glass on the R8 and my analog Canon EOS, and also have lenses with super smooth manual focus and good optical quality for video on my dSLR.
