Why do you own 2 different cameras that need different lenses since you can't aford a $300 betwen both of tehm. just sell one camera and everything with it and spend on one lens system whatever you need. Its stupides thing since slice of bread to use 2 differant systems.-- hide signature --
I agree it does not make sense to have two systems unless you really have a lot of xtra money . But to answer the question the T amron 70 300 IS is good. It's not nearly as good as the Canon 100-400 L IS, but it nevertheless it is good for around 300 bucks.
