Here are a few E-6 (slide film) samples from the Fuji GA645Zi, reviewed here. The Fuji medium format zoom correctly exposes slide film as well as the other versions, so no surprise there. I've added the photos inside to the review, but you can check them out here if you've already seen the review.
Also, I've slightly revised my assessment of the Olympus XA. I was pretty hard on it at the time because I was reviewing the Olympus 35 SP, and Nikon 35Ti at the same time, and the little XA just didn't have the same image qualities as the other two much more expensive cameras.
The list of 135 film keeps growing, the newest is Lomography Potsdam 100 B&W; judging by the samples, it doesn't look like anything special for $8 a roll. Go here for a complete list of B&W film, or color here.
