The Maxxum 7D, labelled Dynax 7D in Europe/Hong Kong and α-7 Digital in Japan and officially named "DG-7D", is a 6.1 megapixel digital single-lens reflex camera, or DSLR, produced by Konica Minolta. It was the top model of their DSLR range; the Maxxum/Dynax 5D consumer-grade model was the other.

The 7D was first announced on 2004-02-12 at the f/2.8. Like the Nikon 18-70 kit lens found with many Nikon DSLRs, this lens was regarded as of high enough quality to do justice to the sensor within the body, unlike the cheap zoom kit lenses found with many DSLRs. In 2006 Sony acquired the Konica-Minolta camera business [3] although remaining inventory continued to be sold, alongside the K-M based Sony α100. On release, the camera retailed for around £1000 GBP; somewhere between the Nikon D300 and Canon 40D.

Physical features

The 7D features a Magnesium alloy body, plastic in the rear, and primarily external controls. The body includes external controls for exposure compensation, flash compensation, focus mode, shooting mode, exposure mode, drive mode, metering mode, white balance, focal area, ISO, and two dials that are used to control shutter speed and F-stop. Presence of the external controls for most functions encourage experimentation without having to traverse through menus.

The 7D's 2.5-inch (64 mm) LCD also doubles as the control LCD. Rather than having a second, status LCD located elsewhere like some Canon and Nikon DSLRs, it displays information such as exposure settings, aperture, shutter speed, battery life, and other miscellaneous recording information. The LCD, when acting as the control LCD, also rotates 90° based on the rotation of the camera to keep all of the information shown upright.

Anti-shake technology

The Konica Minolta Maxxum/Dynax 5D and 7D both come with Konica Minolta's Anti-Shake Technology. A major difference between Konica Minolta's Anti-Shake and Canon's Image stabilization is that the operation is done in the camera itself rather than inside the lens, thus making the effects usable regardless of the lens attached. In Canon's IS the lens has a floating element that is used to redirect the frame based on outside movement. In Konica Minolta's AS, however, the CCD is on a floating plane controlled by two actuators that work based on detected outside movement and create an inverse movement, thereby keeping the CCD in line with the image.

Firmware issues

The factory firmware that the 7Ds initially shipped with (version 1.00) included a few performance related camera issues which affected initial reviews. The next build of firmware (version 1.10) gave such a great improvement in camera performance that DPReview revised their initial review of the 7D to retract a couple of the main negative points, citing true USB 2.0 speeds up to 25Mbit/s (up from 7.5Mbit/s), blinking highlights in the camera's built-in playback mode, the addition of a remote storage function in the transfer modes, and faster times when writing to the CF memory cards.

Other problems

The 7D, in addition to having become a collector's camera, and despite what is now a low megapixel number, is known for taking beautiful photographs, what users of the camera call "those Minolta colors". The camera is loved for its manual controls. It did have one problem which appeared to afflict all of the 7Ds at one point in their working lives: the development of "first frame black" in which after a period of not being used, the first frame turned up dark. Sony for a while fixed this problem, and so did some private camera shops, however the parts which caused the problem are no longer available. First Frame Blank is often a simple process of turning off and back on, though it can lead to blank frames all the time. Another significant problem is misalignment of the sensor, where the sensor is stuck at one of the positions it can take up to counteract camera shake or it fails completely often due to one of the piezo actuators which 'shake' the sensor. There is a chugging sound and no picture can be taken. Repairs for this are prohibitive but are still available at a few specialist centers.

Konica Minolta and Sony

In July 2005, Konica Minolta announced a partnership with Sony to research and develop camera technologies. The following March, Konica Minolta announced its withdrawal from the camera business altogether and transferred all of its camera assets to Sony as of March 2006.

Sony's line of Alpha DSLR cameras built upon the digital Maxxum line, keeping many of the features that made the Maxxum 7D and 5D popular, most notably the built-in Anti-Shake technology. All Sony DSLR cameras came to support the Minolta α mount lens system which makes newer Sony-built lenses compatible with Maxxum bodies and Maxxum lenses compatible with newer Sony bodies.
