One of the best reasons to consider a megazoom is the fact that you get a big zoom range in a small package, so you don't have to carry around huge dSLR lenses and, more importantly, you don't have to pay the huge prices for those dSLR lenses.
For around £180, Fujifilm's FinePix S8000fd sports an 18x optical zoom lens that covers a 35mm-equivalent range of 27mm-to-486mm with a maximum aperture range of f/2.8-to-f/4.5. Given that a lot of megazooms start around a not-so-wide 36mm with their zooms, this camera's lens should make group portraits or big landscapes easier to frame.
With its well-sculpted, rubberised grip and another nicely contoured and rubberised area for your thumb, the S8000fd is more comfortable to hold than some megazooms.
However, the F button, which leads you to the FinePix menu that lets you change ISO, image quality/size and colour mode settings, is located too close to where your thumb goes, and we accidentally pressed it a few times during our tests. Other than that, the buttons are placed well. The only button not on the right hand side of the camera is the flash button, which is logically placed on the left side of the flash itself.
Close scrutiny shows that the FinePix S8000fd has a lot in common with Olympus' SP-550 UZ. Both use 1/2.35-inch CCD sensors that are a touch smaller than the 1/2.5-inch sensor in Panasonic's 18x megazoom . Also, both have the same zoom range, since they have identically-spec'ed lenses, and both include sensor-shift image stabilisation.
Their bodies are very similar in layout, though the Olympus is a touch smaller and has a nice grip around the barrel of the lens, but its main grip isn't as nicely shaped as this Fuji's grip. The biggest difference between the two is that the SP-550 UZ is a 7.1-megapixel camera, while the S8000fd has an 8-megapixel CCD.
The S8000fd includes most of the features you'd expect to find in a megazoom. The two biggest omissions are a hotshoe and raw capture. As mentioned above, the S8000fd includes sensor-shift image stabilisation in contrast to the DMC-FZ18's optical image stabilisation. While sensor-shift IS has a reputation of being inferior to optical IS, we got impressive results from the S8000fd.
In our tests, we were able to capture a sharp image shooting at 1/150th of a second and the lens zoomed all the way to its 486mm limit. Without image stabilisation, we would have had to shoot at 1/500th of a second to get those results. Fuji also includes an ISO-boost mode that they also refer to as an IS mode. However, as always, higher ISOs bring with them more noise and less sharpness.
As has become the trend, the S8000fd includes face detection, but this camera uses Fuji's original algorithms rather than the newer system incorporated into its little sister, the FinePix F50fd. Still, it does a good job of finding faces in your shots and tends to lose track of the faces if it can't find both eyes, while the newer version can find faces even if they are in profile. Once the camera finds the faces, it uses them to help determine focus and exposure so the camera won't make a mistake and focus on something in the background instead of your mum's lovely smile.
Control freaks will appreciate the S8000fd's manual exposure controls, which give you up to 10 choices for apertures spanning f/2.8 through f/8 and 40 shutter speeds ranging from 4 seconds to 1/2000 second. The interface for those controls could be better, though.
Rather than including any thumb or finger wheels, you have to press the exposure compensation button and then use the control pad to set aperture and/or shutter speed. One, or even better two, wheels would make the process a lot smoother of an experience. Still, it's nice to see manual exposure controls with this many choices, since some only include two or three choices for apertures.
