cant live view at all. but when i which to 28-300mm lens i can use the live view function to take pic.
not sure what is the issue.
also the reticle suppose to be red but it turn out to be grey
Hmm....that's wierd, but just to let you know that my case I can. Just use it as any normal lens, can AF (contrast detection method/slow) in Live View, and record. You tried cleaning the contacts? Just a long shot...
