This is a brilliant professional level camera. At one third the price of its Nikon competitor just cant be beaten for value.I used the camera for the first time at a wedding shoot with a real professional and I was actually shocked at the ease of use. Using the Nikon AF lenses as well means that this is a top of the range camera.
With a full range of automatic and manual settings there is no need to be caught out in any situation.
The quality of the output is a good as any conventional film camera that I have seen and because of the resolution, images can be blown up to mammoth proportions.
The six megapixel images are so good that I dont believe that Fuji will go any higher for the forseeable future - so dont be afraid to buy the S2 even at the budget price that the are currently available at.
Buy happy - buy the S2 pro.
