Fujifilm FinePix Z5fd Optics
The Fuji Z5fd has a pretty typical 3x optical zoom, ranging from 36-108mm. It's a folded optical design, which allows the entire mechanism to stay inside the camera while it zoom, something we regard as an essential element for a durable pocket camera; other designs can open while in a bag or pocket, damaging the lens. The main drawback to this design is that your finger can very easily get in the way, because these lenses are usually mounted around the edges of the camera.
Overall, the FinePix Z5fd's lens is quite good, producing good sharpness at most zoom settings, including in the corners. The one drawback is significant chromatic aberration at wide angle. Macro performance is good, and corner sharpness is also good. See the test results below for more.
An average 3x optical zoom, good overall performance. About average digital zoom performance as well.
|36mm||108mm||6.2x Digital Zoom|
The Fujifilm FinePix Z5fd's optical zoom covers the equivalent of a 36-108mm, about average compared to most consumer digital cameras. Details are reasonably sharp at full wide angle, though coma distortion is quite high. Results are much better at full telephoto, with sharp details. The camera's 6.2x digital zoom performs about average, with strong blurring and loss of resolution from digital enlargement.
A very small macro area with good detail and high resolution. Flash exposure is quite uneven, however.
|Standard Macro||Macro with Flash|
The Fujifilm FinePix Z5fd's macro setting performed quite well, capturing a very small minimum area of 1.95 x 1.46 inches (50 x 37 millimeters). Detail and resolution were both very good in the center of the frame, though there's a lot of softening in the corners from the lens. (Most cameras have some softening in the corners in macro mode.) The Z5's flash almost throttled down for the macro area, but still managed to overexpose most of the frame. Coverage with the flash is also quite uneven. Plan on using external lighting for any macro shots with the Z5.
Fairly low barrel distortion, and reasonably low pincushion as well.
|Barrel distortion at 36mm is 0.3%|
|Pincushion at 108mm is 0.2%|
This is the tendency for the lens to bend straight lines outward (like a barrel -- usually at wide angle) or inward (like a pincushion -- usually at telephoto). The Fujifilm FinePix Z5fd's 0.3% barrel distortion at wide angle is actually quite a bit lower than average, though still somewhat noticeable in some images. At the telephoto end, the Fuji Z5fd's 0.2% pincushion distortion is a little higher than what we typically see, but not too bad.
High and bright at wide angle, though quite low at telephoto. Noticeable effect on wide angle images.

Chromatic aberration is high at wide angle, showing about 12+ pixels of very bright coloration on either side of the target lines. However, at telephoto, the effect is much lower, and quite dull. (This distortion is visible as a slight colored fringe around the objects at the edges of the field of view on the resolution target.)
Some blurring in the corners of the frame at wide angle, though good corner-to-corner sharpness at telephoto.
|Wide: Slightly soft in the
corners (upper right).
|Wide: Sharper at center.|
|Tele: Consistent sharpness in the corners compared to center (upper right)||Tele: Slightly soft at center.|
The Fujifilm FinePix Z5fd produced soft corners of the frame at full wide angle. However, at full telephoto, sharpness is consistent from corner to corner compared to the center of the frame. Good performance overall.
