Thanks for the info Peter, I am pretty much a newbie when it comes to these longer lenses having never owned one. I take it that the 360 & 300 share the same lens design? I just sold my next to last 35mm lens so I have the cash to get one now. What to buy, what to buy... I hate making these decisions when there are so many choices, LOL. Guess at the worst if I don't like it I can trade or sell it here.
