Classic SLR Series
One of the most significant development of SLR camera development is the TTL OTF (Through the lens Off the Film) flash exposure control. An innovative idea pioneered by Olympus in their Olympus OM2n in 1975 and it has turned into a mainstream flash mode for the industry. The TTL flash has opened up a great deal of photographic possibilities and Minolta has improved the flash techniques into many ways for the Maxxum 7000. Over the years, Minolta has designed many series of AF flash units for the Maxxum, "i" and "xi" bodies, the later flash units have a double rails designed which is not entirely ISO type standard, however, they can still be attached to the first generation Maxxum bodies via a Flash Shoe Adapter FS-1200 and restore most of the basic flash functions. The early AF flash models cannot be compared with later high-tech flash exposure control incorporated in the camera/flash but the raw form of the flash design appeared during that time was fascinating enough even for seasoned photographers. The dedicated Minolta Program Flash 2800AF specifically for the Maxxum class bodies as a true companion flash. Working with the dedicated flash, it can provide correctly autofocus flash photographs in low light and even in total darkness. In low light, the Minolta Program Flash 2800AF automatically fires a burst of an LED focus assist light to support the camera's autofocus system in making an accurate focus measurement and adjusting the lens accordingly for subjects as far as five meters away.*
The Minolta Program Flash 2800AF - Exciting flash capabilities with simplicity, speed and precision.
* EV 1 at ISO 100 with 50mm standard lens; as determined by Minolta standard test method).
The Minolta Program Flash 2800AF has a maximum guide number of 28 at ISO 100, and provides a wider range of flash capabilities with more precision and less complication than ever before. In Program mode there is no need for exposure settings, calculations, or compensations. Rash duration is precisely controlled by Minolta's Direct Auto flash Metering System to provide optimum exposure. As soon as the flash is charged, a flash-ready signal appears in camera viewfinder and on the back of the flash unit.
Proper exposure is also confirmed in the viewfinder and on the flash when flash operation is within the operating range of the 2800AF. Without attachments, flash coverage is provided for Minolta AF lenses down to 35mm, and down to 28mm with the wide adapter supplied.
Automatic Charge Control To improve battery life, both Minolta Program flashes have a special automatic charge control circuit that automatically switches off power fifteen minutes after the flash unit reaches a full charge. Charging will automatically resume the moment your finger touches the operating button.
The Minolta Program Flash 4000AF Greater power and motorized flash coverage.
The original flash designed for the Maxxum 7000 was the Minolta Program Flash 2800AF, the Minolta Program Flash 4000AF was almost a year late after the debut of the Maxxum 7000. The Minolta Program Flash 4000AF is the perfect unit for the serious Minolta photographer. Its built-in power zoom head automatically adjusts flash coverage for 28mm through short-telephoto Minolta AF lenses and also tilts and swivels for bounce-flash operation. Six settings control flash power up to guide number 40 at ISO 100. An LCD data panel on the back of the unit keeps you well informed of all operating conditions. The 4000AF is controlled by the 7000's exposure system, so readouts on its LCD data panel automatically change as the camera or lens controls are operated to keep you informed during operation.
Your Minolta 7000 and Program Flash 2800AF Combination provides a perfect formulation of sophisticated professional flash techniques and capabilities. Some of which are:
Automatic Fill Flash. A special daytime flash program to prevent subject being overexposed The Minolta Program Flash 2800AF utilizes a special fill-flash program that is built into its micro computerized circuitry to solve a specific flash exposure problem. In conventional fill-flash photography, flash exposure is added to ambient light exposure with the result that-all too often-the subject becomes overexposed. In Program mode with bright subjects, the Minolta Program Flash 2800AF controls flash duration and aperture to provide optimum subject illumination. Above EV 12, the Minolta Program Flash 2800AF automatically switches from 1/60 sec. to 1/100 sec. with the result that dark shadows are lightened without washing out important highlight details.
Any-aperture TTL Autoflash. Expand your creative use of the Minolta 7000. When the Minolta 7000 is set to Aperture-priority or Manual mode, you can select any available aperture with the Minolta Program Flash 2800AF. This lets you choose large apertures to obtain maximum flash range (e.g. up to 20 meters with the 2800AF and 28 meters with the 4000AF at f/1.4 and ISO 100) or to select smaller apertures for selective depth-of-field control. With the aid of the Minolta Direct Auto flash Metering system, flash duration is precisely controlled according to the aperture in use. There is no need to make any calculations or compensations.
Slow Shutter Autoflash.
Another creative feature to give you photographs that professional look. Slow shutter auto flash enables you to "burn in" the background behind your subject in order to obtain better background detail. At the same time, it also creates a more natural lighting balance between the subject and the background: no harsh shadows, no sharp relief. In the Minolta 7000's Aperture-priority mode, flash sync speeds slower than 1/100 sec. can be obtained by using the camera's AF Lock.
Creative M-mode Auto flash
Further, you can also use the Minolta Program Flash 2800AF or the more powerful 4000AF together with the Minolta 7000 in Manual mode. Any shutter speed below 1/100 sec and any aperture can be combined for either specific creative results or for the sheer fun or experimenting.
Sequential Flash Exposures. Again, simplicity combines with precision to get the results you want. With the Minolta 7000 and the Minolta Program Flash 2800AF in its "Lo" power setting or the 4000AF to its motor-drive setting, you can shoot sequential flash photos while employing autofocusing by repeatedly pressing the camera's operating button. With manual focusing, sequential flash photos up to two frames per second can be taken with the flash in " Lo'' power setting.
Faster flash recycling and automatic lighting-ratio control.
The Minolta Control Grip CG-1000 attaches cordlessly to the Minolta 7000 to provide more rapid recharging of the Minolta Program Flash 2800AF. When the Program Flash 2800AF is attached to the CG-1000, the AF illuminator Unit Al-1000 must be placed in the hot shoe of the Minolta 7000 in order to utilize autofocus flash operation.
The Control Grip CG-1000 also provides automatic lighting-ratio control. When two flash units are used, the CG-1000 automatically controls its flash and the flash mounted on the camera's hot shoe in a 2:1 ratio, allowing you to attain professional portrait-lighting effects with astounding ease! The Minolta Grip Extension Cable EC-1000 permits 5 meter separation from the camera itself. Multiple flash units can be accurately controlled while Minolta Direct Autoflash Metering assures accurate exposures without calculations or calibrations.
