Compromises of a bridge camera with a long zoom
Discussion
Santa brought my little lad a Fuji S4900 bridge camera. He's chuffed with it as in his eyes it is a 'grown up' camera and he likes the big zoom.
I feel that every image it produces is blurred at the peripheries of the frame. It is really starting to bug me and I'm beginning to think it might be faulty.....or do you think that as it has a 30x zoom then this is likely to be a compromise of having such a lens?

Even expensive lenses have problems around the edges of the image, you won't get an evenly sharp image.
The most common fault with bridge zooms is decentering, and its easy to check for.

A4 is good enough for this kind of test, A3 is better.
Make sure the chart is hung flat with tape against a flat wall. Measure the height of the centre of the chart, put camera on tripod or chair with books at same height, make sure shot fills the screen, take picture ( preferably using timer to avoid shake ) and check the corners.
As above though, even expensive lenses can be slightly decentered...some slight variation is normal.
Post the results on here and I will take a look.

I've got the HS30, great camera. I have accepted a compromised between the bridge and a normal camera. At full 30x zoom the pics are not as clear (still good quality though). However, your pics looks like you have a faulty lens. I say that on the blurred area is always on the left. I had something similar when a glass In the lens slipped, which I had repaired under Fujis European warranty.
That looks like a classic bridge camera decentered lens issue. As the sensors are so tiny, it take just a very small deviation to produce that effect. The manufactures normally produce the lens and sensor as a single package to try to solve the problem of alignment, and they are very hard to service.
I would be going down the warranty route with that one personally.
