FujiFilm FinePix 4700

December 17, 2000

Perfect camera, one of the best in the compact camera class. It's pleasant both to look at and to hold in the hands, not in vain the cameras of such design are produced not only by Fuji but also by Leica. (Today's hero has its own sister LEICA DIGILUX 4.3)

This camera was announced 4 Mpixel (it shows the number of pixels of in an image), though the matrix of this camera has only 2.4 Mpixel as for sensing elements.

Imagine a simple chess-board. In a usual matrix sensing elements are located on each square of this chess-board, and in our case they are situated i.e. only on black squares. In order to record an image in a standard file, you'll have to write something in white squares or you are to think out your own format. Kodak has already faced such problems in cameras of DC120 type. There, when recording information in order not to take place purposeless on the memory cards they used KDC format, which when recording on the computer was converted into standard one. Fuji has taken a way of recording non-standard image into a standard file. Of course it's not economic usage of the space on the memory card but it's quite universal.

A frame of 2400 X 1800 pixels in size due to measurements in 2400000 pixels. The shots of the resolution chart showed that the camera has 1300 vertical grooves per frame, what is similar to other 2X Mpixel brothers, and it lags behind 3-Mpixel ones. But all pixels turn to be in similar situation, and resolution doesn't practically depend on a channel. However all this concerns resolution of monochrome imagery. Color image of all cameras of this price range can be obtained by interpolation on the neighboring pixels.

Spectral characteristics of this camera don't differ significantly from others, but we should notice that we observed sensitivity of the blue channel to the long-wave spectrum part. It's possible that in front of the matrix there is no a filter that cuts off infrared spectrum component. Though, this effect can be explained differently.

The idea, that such positioning of sensing elements allows increasing sensitivity, failed after we had tested this camera. At the rated sensitivity of the matrix 200, 400, 800 ISO a comparison of exposure and aperture values with the values of an exposure meter showed the sensitivity 4 times less. We carried out measurements on brightness of the sky and a gray screen alight with 500 W lamp with a reflector (2 m away). ISO=200

So, the real sensitivity of this camera isn't a bit different from an average value.

800 ISO sensitivity causes a noticeable shift in the color balance. Below are fragments of the photo of a white screen alight with a halogen lamp. The white balance was forcibly set in the position "Incandescent lamp".

I think that marketing tricks of this company are wasted labor. This camera is intended to serve as record book. Constant shooting doesn't live here. It's perfect as a photo record book: it's equipped with 3x zoom lens system, option to record clips with sound, indication of singled out parameters. It means this camera doesn't make you think - it just informs you of exposure and aperture for the upcoming shooting, and let's you correct it in the menu Exposure Correction. Besides, there is manual focusing, sensitivity setting, white balance, exposure measuring method, screen brightness adjustment etc., etc. That is, there are enough options to fix any event.

Video shooting is a bit damaged with impossibility to use an optical zoom (only a digital one). Besides, the focal length is set for minimum, that's why an image obtained had too minute details.

This small camera is fed with two AA rechargeable batteries. The matter is that it takes the same energy as the others but voltage is two times smaller. It means that it must take two times increased current.

The table shows currents in different modes:

Mode Current, A
Shooting. The screen contains only information
Shooting. The screen serves as a viewfinder
Shooting. The screen serves as a viewfinder + lens engine

Interestingly that when the camera displays just information without viewfinder functions it takes much more energy.

In general, handling is quite pleasant: you have a round LC indicator which demonstrates joystick functions in different modes.

Unfortunately, an optical viewfinder disappointed us a bit as it lacks for option of dioptre setting. However, lens optical characteristics are very close to that of a human eye, so it allows shooting right through eyelens, with an image taking almost the whole area of a frame (usually it's necessary to choose a special lenseye for a camera). As an example you can see several shots made with different microscopes.

The simplest microscope "NATURALIST" gives decent quality:

And with an ancient microscope from Carl Zeiss the quality is just perfect:

Fragment diminished two times as comparing with an original. A miniature of the whole frame and shooting parameters can be seen on an illustration devoted to the program Exif Viewer which goes further.

The camera is supplied with a program Exif Viewer. Interestingly that it contains data fields received with the help of GPS.
