The only negative I reckon is the somewhat unusual manual. It is in my opinion, for what it is worth, not very user friendly. I am only just coming to terms with it now. As far as its performance and construction, I believe it is 1st class. Yeah I know there are better, but they are also a lot, lot more expensive. As it is, I paid around $5500 for the G11 and Gemini, but that was when the Aussie dollar was absolute crud, so it is probably a little cheaper now.
Just my 2 cents worth.
