Maximum flash-sync shutter speed is 1¼180 with Anti-Shake switched off,
and 1¼125 with Anti-Shake activated. Attach an optional Program/Maxxum
Flash 5600HS(D) or 3600HS(D), and you can use high-speed sync, up to the camera’s
maximum 1¼4000 shutter speed (albeit at reduced range).

Image quality is excellent at the lower ISO settings (this was
hand-held at ISO 100, 1¼45 at f/4.5, AF 17–35mm f/2.8–4.0
D lens at 35mm, equivalent to 52.5mm on a 35mm camera).

Digital Features
At the digital heart of the Maxxum 7D is a 6.3-megapixel (6.1 image megapixels)
23.5x15.7mm CCD image sensor. Because it’s smaller than a full 36x24mm
35mm film frame, the sensor “crops” the image formed by the lens
more tightly, yielding the field of view of a lens 1.5X longer. Thus, a 100mm
lens on the 7D frames like a 150mm lens on a 35mm SLR. This is great for sports/wildlife
shooters, whose telephoto lenses all in effect become 50% longer; but not good
for wide-angle buffs, whose wide-angle lenses also become 50% longer (that 28mm
wide-angle acts like a 42mm “normal” on the 7D). This isn’t
unique to the 7D; all digital SLRs in this category have similar-sized image
sensors and crop factors.
The Maxxum 7D lets you shoot JPEG images at three resolutions, with three image-quality
settings (levels of compression) for each, plus unprocessed RAW images at maximum
resolution (6 megapixels, 3008x2008 pixels), and simultaneous RAW + JPEG recording.
RAW images provide the best image quality, but require processing in the computer
using special DiMAGE Viewer software provided with the camera. JPEG resolution
choices are 6 megapixels (3008x2008 pixels), 3.4 megapixels (2256x1496 pixels)
and 1.5 megapixels (1504x1000 pixels). Quality levels include Extra fine (1/2
compression), Fine (1/4) and Standard (1/8).

The Maxxum 7D’s Anti-Shake system moves the image sensor
rather than lens elements.

Of course, image quality is more than a matter of pixel count. The Maxxum
7D employs Minolta’s CxProcess III image-optimization technology and Advanced
LSI image-processing engine to maximize image quality and speed up camera operation.
In a nutshell, they seem to do their jobs very well.
You can adjust sharpness, contrast, color saturation and hue in five steps each
via the Digital FX monitor menu. There’s an auto white balance setting
(which worked quite well) plus six presets, a mode that lets you set a specific
color temperature, and a custom mode that lets you determine white balance for
a specific lighting situation. You can choose among Natural sRGB and Natural
Plus sRGB (with increased contrast and sharpness) color space, or the popular
Adobe RGB color space. There’s also Zone Matching, which improves high-key
and low-key images.
The Custom Menu is similar to custom functions with film cameras, allowing you
to tailor the camera to your tastes by changing functions of some of the buttons
and displays.
One especially nice feature is that you can store up to three sets of camera
settings, and return to them at any time merely by rotating the mode dial to
1, 2 or 3.

That huge 2.5-inch LCD monitor is a delight for reviewing images
and setting the camera, yet leaves plenty of room for controls and
the right thumb.

In Use
That Anti-Shake system really works. I was able to get sharp shots hand-holding
the AF 100–300mm f/4.5–5.6 D zoom at 300mm (effective focal length
450mm with the camera’s 1.5X crop factor) at shutter speeds down to 1¼60.
At 230mm (345mm equivalent focal length), I got sharp results down to 1¼15,
and with the 17–35mm f/2.8–4.0 wide-angle zoom Konica Minolta introduced
with the camera, at the 17mm setting (25.5mm equivalent), got sharp images at
speeds as long as 0.3 second. Shots made at these shutter speeds with the Anti-Shake
switched off were noticeably less sharp.
The camera has a solid traditional-SLR feel. That big LCD monitor is easy to
read, and made it easy to evaluate images right after shooting them, as long
as direct sunlight wasn’t falling on it—as with most LCD monitors,
the images are harder to see in bright light. The LCD monitor menus are easy
to navigate via tabs at the top. The shooting display and just-shot images (but
not the actual menus) automatically rotate with the camera when you change between
horizontal- and vertical-format shooting. And it’s wonderful to be able
to set a lot of stuff without going to the LCD monitor menus, thanks to all
the well-positioned dials and buttons.
With the AF system set to wide focus area, autofocusing in dim light was quicker
and more accurate than with other digital SLRs we’ve used (selecting one
of the peripheral AF areas resulted in lower performance). With action subjects
in good light, autofocusing was competitively quick and accurate (when activated,
the Anti-Shake system slows focusing a bit, since the camera must focus, then
stabililize). Autofocusing isn’t as silent as with, say, Canon’s
Ultrasonic lenses, but overall performance is excellent.
With some lenses (including the 100–300mm zoom I used in our tests), there’s
drag on the manual focusing ring in manual focusing mode. The instruction manual
gives a procedure to work around this, but warns that doing so can reduce metering
accuracy and Anti-Shake performance. Hopefully a firmware or other “fix”
is in the works for this.
The 14-segment honeycomb metering was “bulletproof” with one exception:
it tended to overexpose white subjects in harsh sun, no matter what the background
tone, and even when they nearly filled the frame (this could be more an image-sensor
matter than a metering issue). Tonality in white subjects in softer light was
excellent; in hazy sun I even photographed a white duck next to a near-black
coot in direct sun, and the image recorded detail in both (enough to pull out
with Photoshop).
Sharpness, color and noise are excellent at lower ISO settings, surprisingly
good at ISO 800 and not bad at ISO 1600. ISO 3200 should be reserved for emergencies,
as image quality does deteriorate noticeably at that setting, but it’s
nice to have that capability when it is needed—I used to keep a roll of
Konica’s now-defunct ISO 3200 color-print film in my camera bag for just
that sort of emergency.
|
Image quality is good at ISO 1600. The EXIF metadata indicated
the exposure for this hand-held shot was 2.5 seconds at f/5.6
with a 17mm focal length and Anti-Shake on.

As mentioned earlier, the quick start-up and wake-up times are a real blessing,
not just for my quick and erratic bird subjects, but for any photography. Few
things in photography are more annoying than seeing something great happening
and having to wait one second, two seconds or longer while the camera wakes
up. That’s not an issue with the 7D.
That big easy-to-read LCD monitor made setting the camera simple—it was
great not having to dig out my reading glasses every time I wanted to change
something. And the Recording Mode display puts it all right there in front of
you. I also appreciate being able to set frequently changed camera adjustments
via dials and buttons, without having to scroll through monitor menus.
The camera comes with a rechargeable lithium-ion battery and charger (we got
375 and 383 shots per charge, with the camera switched on the whole time, Anti-Shake
active for around 90% of the shots, and continuous AF mode used for more than
half of the shots, but no flash), a nice wide neckstrap, a USB cable, a video
cable (to connect to a TV set), DiMAGE Viewer software and manual, a very clear
all-English camera instruction manual, and a handy (but multi-language) pocket
reference guide that really does fit in a pocket.
Bottom line: If you’re a Maxxum film SLR user with an
investment in Maxxum lenses, the 7D is your ticket to serious digital photography.
If you don’t already have a bagful of Maxxum lenses and are in the market
for a good digital SLR, you still should consider the 7D for its Anti-Shake,
quick start-up and wake-up, big LCD monitor, and excellent performance and image
quality.
