Although I have never felt that camera gear has anything to do with great images, I must admit that I have GAS (Gear Acquisition Syndrome)! It is...unfortunately incurable. Here are only some of my favorite cameras!!
Noblex - German made unusual medium form camera that has a swing lens. Creates a 50x120mm negative.
Leica M9 - Best "Film Like" digital camera that I have ever used. 18.5 megapixel full frame sensor.
Olympus Pen EP2 - A very compact, interchangeable lens systen based on the Micro 4/3 digital sensor. 12.3 Megapixel and great at HD movies. I love my Nikon D90, but the small size and quality of this system makes it so great to travel with and to do street photography.
Rolleiflex 80mm F2.8 Planar - Ahhh the romance of the Rollei. Makes me want to sit in a cafe in Paris. A medium format camera that creates square 60 x 60mm negatives. Also, German made.
Hasselblad xPan - An amazing and rare 35mm rangefinder camera that can shoot 35mm or panoramic images on the same roll of film. The panoramic negatives are double size resulting in a 24x65mm negative. This camera produces stunning images.
My main Medium format camera is the Mamiya RZ. This camera can produce 6x7, 6x6 and 6x4.5 negatives. It shoots both 120 and 220 film magazines and Polaroid as well as Quadra 72 4x5 sheet film backs. It's not light or portable, but the negatives are fantastic.
