T2 is fantastic. My sharpest point and shoot. I have two I like it so much for the day my first dies. I've had a G2 for many years, awesome camera. The 35mm lens is the only one in the line up I've sold off. A decent lens, just nothing special compared to the 21/28/45/90 of the G line up which are blow-away amazing. G1 is ok but G2 autofocus quite a bit better. If you can afford get the G2. If you do go the G1 route be sure it's one that has been upgraded to handle the 35mm if you insist on that lens (green sticker inside).
