I have owned the Fuji Finepix S3 Pro camera for around a year as a professional photographer. And I must say that the results of this camera are great. If you were thinking of upgrading then think carefully.
The 9500 cameras are pretty poor when it comes to this gem. But compared to other cameras then its not so great, but you do have to play things off.

The biggest issue is the buffer, take around 3 shots and its full and take a considerable time to clear, so anyone wanting to take a number of continuous shoots should avoid this camera.
The image quality from this camera is outstanding, colour depth and details are very good, it can go a bit saturated when it gets hot which I find it can do on summer weddings.

ISO goes up to 1600 and it is pretty clean, Compared to the Cannons I have seen, it would be like a 600 and 800 on the Nikon, To be honest, I don't use Nikon or Cannons in low light since I have this camera so the comparison may be a little off.

Battery life is pretty good; using two sets in a single day on a shoot was pretty reasonable to me.

There is plenty of lens available, if you do go cheap then you will find focus issues and the camera is based on older technologies than say a Nikon D200 you will also find that using a great speed light (SB600-SB800) that the TTL will not work correctly.
There has been report of the USB port breaking but I have not really use the USB port as I have a Card reader.

But with all that said, if you really like photography and know how to use a camera and flash you wont go far wrong.

Sadly these are out of production and can be purchased for around £500. The S5 so I am told has not made much of the improvements that many photographers wanted, so there isn't much difference.

The Fuji S3 Pro is and feels very nice and works OK in the studio. Outdoors it is not so good for action photography.
