The Innovative Total Focusing Control System

DYNAX 7 sets an entirely new standard of focus ease, accuracy and convenience with the super-wide focusing area and 9-point AF sensors with centre dual cross-hair sensors.

9-Point Sensors with Centre Dual Cross-Hair Sensors

The DYNAX 7's ultra-wide focus area is covered by 9 AF sensors which include the world's fastest centre dual cross-hair sensors. These sensors increase AF speed and accuracy.

9 Focus Areas Selection

Spot AF button and focus area selector enable truly flexible and creative photography. Focus area selector selects wide or local focus areas. The inner spot AF button selects the centre dual cross-hair sensors as the focus point. And the focus area selector enables you to freely choose a specific area of your shot in the local focus area.

AF/MF Control

The AF/MF button allows you to instantly switch between AF and MF without removing your eye from the viewfinder, and enabling you to maintain holding balance.

Direct Manual Focus (DMF)

Direct Manual Focus mode allows you to quickly adjust focusing after the focus is locked in AF mode. Pressing the shutter release half way activates and locks AF, in addition to releasing the internal clutch. This frees the focus ring, permitting you to focus manually, primarily for close-up or portrait shots. In this way, you benefit from the convenience of AF, plus the additional creative control of MF, without changing modes or settings.

*Requires custom functions

High Performance AF Control

The DYNAX 7's advanced AF system has greater processing power and improved AF software which allows it to analyze metered data and compute the speed and direction of a moving subject.

The World's Fastest AF Control*

The autofocus control's twin high-speed 16 bit CPU have a computation speed that is approximately 5 times faster than that of previous models. In addition, the predictive focus control's accuracy has almost doubled when compared to prior models.

*As of August 25, 2000. When using a 50mm f/1.4 lens under Konica Minolta's standard test conditions.

4 frames per second Continuous Drive

The high-speed built-in motor drive allows continuous shooting of moving objects at 4 frames per second in MF mode*.

*3.7 frames per second in continuous AF drive.

(Without the aid of an external booster).

Predictive Focus Control

Multi-Dimentional Predictive Focus Control System is capable of tracking abrupt changes in speed and direction, such as U-turns, while maintaining accurate focus.

ADI Flash Metering System

The new flash metering system delivers the highest level control and accuracy of any SLR in its class. What's more, it offers the optimum flash metering regardless of the background conditions or the subject's reflectance.

ADI Flash Metering

Konica Minolta's ADI(Advanced Distance Integration) flash metering works in combination with the DYNAX 7, D lenses, Program Flash 5600HS(D) and Program Flash 3600HS(D), as well as the built-in flash. When used with these flash units, the camera calculates a guide number to control TTL flash metering. This guide number is calculated according to distance from subject, ambient light and pre-flash reflectivity of the subject and the background. It allows the ADI Flash Metering System to offer optimum flash metering regardless of the background conditions or subject's reflectance characteristics.

Remote Off-Camera Synchronization

Beautiful, off-camera flash results are yours with the Program Flash 5600HS(D) and Program Flash 3600HS(D) units. The flash units are wireless, making setup fast and easy, and simplifying the dramatic technique of multi-flash photography when used together with the camera's built-in flash. And both units are designed to handle shutter speeds as fast as 1/8000 seconds, allowing you to freeze motion or change the aperture for a defocused image effect.

Rear Curtain Flash Synchronization*

When shooting moving subjects with a flash at slow shutter speeds, Rear Curtain Flash Synchronization is a must. Rather than illuminating the subject at the beginning of the movement, as with a conventional flash, it illuminates the subject just before the rear curtain is driven at the end of the exposure. This causes the trails of the light to follow instead of precede the image, so the movement looks natural.

*Not possible in remote off-camera flash shooting

Comprehensive Exposure System

Advanced and precise auto exposure gives instant, accurate response to lighting condition, plus the control you need to realise your vision.

Impressive Metering System

A 14-segment honeycomb-pattern metering covers the entire frame to collect data and determine the precise exposure for the main subject. By using center-weighted average metering, 80% of the metering sensitivity is concentrated in the center area. With spot metering, sensitivity is concentrated in an area of 5.5mm, 3.3% of the total frame area, for accurate metering of specific areas of your subject.

3 Programmed Utility Modes and 3 Creative Modes

P (Programmed AE) mode automatically sets optimum aperture setting and shutter speed to match any shooting situation. PA mode let's you control depth of field by adjusting the aperture setting while in P mode. And PS mode allows adjustment of shutter speed while in P mode.

A (Aperture priority) mode offers superior command of depth-of-field, for excellent results when shooting portraits, landscapes or macro images. S (Shutter priority) mode allows selection of shutter speeds from 1/8000 to 30 s. And M (Manual) mode offers fine adjustments to both aperture and shutter speed.

Manual Shift

When using manual shift in M mode, you can instantly change the aperture/shutter speed combination without changing the exposure value, by turning the front dial and holding down the AE lock button simultaneously.

Easy-To-Use Operation For Your Convenience

The Dynax 7 offers the ultimate operation system : familiar dial controls that are easy-to-understand at-a-glance and a large dot-matrix Navigation Display that comfirms user information.

Navigation Display

The navigation display helps you command the DYNAX 7's power and versatility. It's easily large enough to give you fast, at-a-glance confirmation of the operating parameters you set with the familiar dial-type controls. A vast range of information is available in five different languages, and you can choose between detailed display, large-icon, meter-index and exposure-history display depending on your needs or your own personal preferences. The navigation display is backlit to aid night-time or low-light operation. The display will illuminate for five seconds, however, the time can be extended for as long as operations are continued.

[Primary-Data Displays]

The navigation display shows you all the settings for your selected operating mode. Choose between detailed information display, large icon display (easier to see, but shows less information-just major parameters) or vertical display, which is automatically selected when you rotate the camera.

[Image-Data Displays]

Meter-index display, Exposure-history display, Data-memory display

Meter-index display is useful for adjusting exposure values when the eyepiece is covered for tripod photography. Exposure compensation, difference between meter exposure and manually set values, exposure bracketing, and exposure and flash compensation can all be displayed here. Exposure history shows the current exposure data and the previous five frames. Data-memory display shows stored data such as shutter-speed, aperture value and exposure compensation for each frame.

[Operational-Data Displays]

Custom-functions display allows you to store and reset your most used settings for instant recall. A choice of Japanese, English, German, French and Spanish are available.

Personalized System

[Memory Function]

The DYNAX 7 has three user-programmable memory locations for settings, accessible from positions 1, 2 and 3 on the Exposure-mode dial. Operation is simplicity itself. Just set up the camera the way you want it and hold down the enter button. The navigation display confirms the items to be stored. When you release the enter button, you will be prompted to specify a user location which you choose with the exposure dial. Then press the enter button again, and your settings are stored for instant recall.

[Data Memory Function]

Eleven items of data for up to 7 rolls of 36-exposure film are automatically stored. Saved data can be recalled and shown on the navigation display at any time, giving you a complete record of shooting data.

[Custom functions]

A total of 35 custom items allow you to set the DYNAX 7's default settings, so it truly becomes your personalized photographic tool. Of course operation is simple, with all data clearly shown in the navigation display. You can quickly and easily change any of the custom items at any time, to suit specific shooting situations without the need for constant referral to the operating manual, as with conventional cameras.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

Electromagnetic diaphragm control system

Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/ on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front and/or rear lens elements over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
