How does Fuji ga645 open the film box?

GA645ZI is a medium format paraxial camera with auto-focus and multiple exposure modes, and its size and weight are relatively small. The standard film frame is 56×4 1.5mm, and 16 (120) can be shot, and 32 can be shot in 220.

It is also the only camera in 645 frames that can use AF and has a zoom lens in the 120 portable paraxial camera. The most suitable users are photographers who need high quality, such as photographers who work for high-end magazines, travel photographers or wedding photographers. In addition, many elderly photographers especially like it. For them, it can achieve high-quality pictures and is very light. At the same time, many elderly people will find manual focusing difficult to use, and the AF function of GA645ZI is more practical.

Fujifilm's Fuji Dragon lens has always enjoyed a high reputation. In the early years, Fuji Dragon lens product line was relatively long. At present, Fuji Dragon has stopped producing 135 lens, but its products still include portable digital camera lens, medium format lens, large format camera lens and even very expensive HDTV camera lens.

GA645Zl's lens is an interesting 10 set of 55-90 MMF/4.5-6.9 super EBC Fuji Dragon lens, and the viewing angle is approximately equal to the range of 34-56mm focal length lens of 35mm camera.

The zoom ratio of this lens is very small, less than twice. Strictly speaking, it is not a zoom lens, but a multi-focus lens with only four focuses. The focal lengths are set to 55mm, 65mm, 75mm and 90mm, which are equivalent to the focal lengths of 34mm, 40mm, 46mm and 56mm of 135 camera.

Choosing multi-focus instead of zoom is also easy to improve the image quality from the design. In fact, the imaging quality of this zoom lens is basically the same as that of other 645 cameras in Futu, and it also adopts Fuji's famous super EBC multilayer coating. There is no obvious dark angle at the wide-angle end. The resolution is good, plus a border of 645. If there is a job that requires high printing, it will have obvious advantages over the 35rrlm camera, which may be the main function of this camera. In terms of color, this lens is also neutral in performance. If the color and light perception of the subject are excellent, you can shoot very good results. Of course, it is not recommended to compare you with lenses like Zeiss and Schneider in color and level. In fact, the price of many lenses in Hasselblad is much higher than that of 645Zl, and the price of the whole camera is much higher. Considering such a low price, you will feel it's worth it.

The aperture of this lens is also relatively small, but it is a mirror shutter. The vibration of the machine is relatively small. You can also try to shoot by hand at a shutter 2-3 levels lower than that of a SLR camera. Remember, always hold the camera with both hands. Press the shutter as gently as possible.

For photographers, it may be obvious that the lens is not wide enough, but for medium format, if it is made wider, the lens volume will increase a lot, and it will lose its significance as the most portable camera. Moreover, the current focal length is the most common and reasonable for photographers.

The shutter of GA645Zl is an electronically controlled inter-mirror shutter. 2- 1/700 seconds, and there is a door B. There are four exposure modes (P, A, AS, M). However, in the automatic gear, when the aperture is fully opened, the shutter speed can only reach 1/400 seconds; the manual maximum shutter speed can only reach 1/400 seconds. The material of the fuselage is nothing special, but the reliability is quite good. Even if it is used in the field at MINUS 20 degrees, there is no problem. I know some climbers use it even in worse environments.

GA645Zl's viewfinder is vertical. It's really convenient if you like taking portraits. And the field of vision is bright, and the display inside is rich enough, ranging distance, aperture, shutter speed, exposure compensation, flash. The display screen is big and bright. With automatic aberration correction, the visual range is 92%, which is not bad.

GA645Zl adopts active and passive hybrid autofocus. There is also a manual focus mode (MF). The dial is set, which is convenient for taking pictures at night, in the scenery and through the glass.

It is reported that the AF system of the aircraft is not very accurate. This statement is not accurate, but its autofocus system does focus slowly in dark conditions, but this is a common problem of autofocus cameras, including Condex G2, Leica MINI LUX and so on. Overall, its AF effect is good. Moreover, the focus of 645Zl is displayed on the right side of the viewfinder, which is easy to see. If you have doubts about the focusing result of the camera, you can take a look before pressing the shutter, which is also very convenient.

GA645ZI hAS four exposure modes: p, a, as and m, in which as means slow grating flash synchronization can be performed. AS file is very useful, because in A or P file, the machine will set the exposure combination to F8, 1/45 seconds, and then automatically adjust the output of the flash, which is not reliable and will cause the background to darken. However, using AS mode is actually a combination of flash and internal aperture priority mode, which can record more background light and ambient light. However, because mode may blur the image because the shutter time is too long, if you don't use a tripod, you should reduce the exposure compensation by two or three steps.

It is also convenient to operate this machine. Many times when you need to operate quickly, you can do it with one hand. The ISO adjustment on the main dial and the conversion of four exposure modes (P, A, AS, M) are all locked, which can be changed by pressing the lock key, which can effectively prevent misoperation. GA645ZI is similar to 135 camera and much more convenient than traditional medium format camera. In addition, GA645ZI can recognize the barcode of the film and know the sensitivity and type of the film, but it can only recognize fujifilm. In addition, when loading the film, we should pay attention to make the two axes of the film tightly wound to prevent light leakage.

In addition, it should be mentioned that the metering method of this camera is non-mirror metering. Pay attention to exposure compensation when matching polarizer or other filters, and the photometric results are very accurate, so there is no problem in taking a reverse film.

The machine has a built-in flash with an index of 12. I think this is a very thoughtful design. After all, the lens aperture is small, and the flash can fill the light when the light is dim, so I often use it instead of a pocket laptop. This kind of "traveling around the world by one plane" is quite individual and convenient. Hot boots have only one flash contact. The original factory also provides a special external flash bracket, which can connect a flash.

A very important function of Fuji GA645 series is to automatically record shooting data while shooting. Data is recorded outside the film exposure area, which may include recording: date, time, exposure data, exposure mode, focal length, aperture, shutter speed, exposure compensation, focus mode (AF/MF), whether to flash, etc.

The layout of 645Zl is relatively simple, but some useful settings can be made by using key combinations. For example, by pressing the AF key to turn the switch to ISO, you can set the adjustment distance unit and switch meters or feet. Press and hold the selfie button and then turn the switch to ISO setting. On b or Off b will appear on the LCD screen, indicating whether there is a "wow" sound prompt after focusing accurately.

In addition, it should be mentioned that the electronic shutter of GA645Zl has a certain life. Press and hold the compensation key, turn the switch to ISO setting, and the LCD screen will show how many times the shutter has been released. After more than 3000 times, the shutter error may exceed the allowable range, so it is best to send it back to the manufacturer for repair before continuing to use it. At present, this work can be completed in Hong Kong.

GA645Zl has no fatal shortcomings. Maybe the automatic voice is a little loud, but it's not a big problem. For amateurs, the aperture of the lens may be relatively small, but there is no universal machine. The main significance of GA645ZI lies in its lightness and convenience. In fact, many professional photographers who use large and medium formats use this camera as a backup machine for capturing pictures.

With the development of equipment, Fuji 645 series including GA645ZI has been discontinued. Many GS and GA series cameras can be bought cheaply in foreign second-hand markets, especially the models of fixed-focus lenses. GS series manual focusing only needs two or three thousand yuan. GA series fixed focus models are around 4000 yuan, GA645ZI is around 8000 yuan, and Fuji 67 and Fuji 69 are around 10000 yuan.

For photographers, if you want to find a camera with good imaging, low cost and hand shooting in most cases (which is very important for those who are not used to carrying heavy tripods), GA645Zl is very practical. However, generally speaking, GS and GA series cameras are based on professional photographers, which are not suitable for equipment enthusiasts.

If you are satisfied, please accept it. Thank you.
