Alpha DSLR-A100K
The Alpha DSLR-A100K is the ? rst of a new line of Sony digital SLR
cameras, and this 10.2-megapixel powerhouse is an in-your-face challenge
to the SLR old boys’ club. It’s the ? rst SLR released by the Sony and Konica-
Minolta collaboration. Compact and well balanced, the A100K reduces menu diving considerably, thanks to its innovative Function Dial. By turning the dial and pressing its center button, you can access metering modes, ? ash options,
focus, ISO, contrast, saturation, sharpness, white balance, and control
over the dynamic range of the image. Each function’s options are displayed on
a 2.5-inch LCD, ready for ? ne-tuning with the camera’s rocker switch. The A100K has a separate mode dial with six preset scene selections in addition to the advanced settings. With a top shutter speed of 1/4,000 second, continuous shooting of up to three frames per second, and a ? ash reach of more than 40 feet (at ISO 1,600), there isn’t much that you won’t be able to shoot.
BUDDING SLR CAMERA
We got a big kick out of the A100K’s autofocusing system, which uses an
IR sensor under the view? nder that triggers the focusing when you bring the camera to your eye. As for the ? ash, you have to lift it up with your ? ngertip—
how quaint! On the other hand, you can be sure it will never ? ash when you
don’t want it to.We slid in the camera’s 750-shot rechargeable battery, inserted
a 2GB SanDisk Extreme IV CompactFlash card (you can also use Sony’s Memory
Stick Duo cards with an included adapter), and set off to shoot local ? ora and fauna. The camera turned on in about a second, focus was quick, shutter lag was a nonissue, and shot-to-shot time was as fast as we could click ’em, even when using the 3-frames-per-second continuous burst mode. Colors reproduced accurately with good saturation, and big images printed on Epson’s Stylus Photo 2200 inkjet printer showed excellent detail. The A100K’s sexiest feature is its antishake capability, called Super SteadyShot. It works with any lens, and when
turned on, it shifts the sensor to cancel out camera movement at slow shutter speeds. We tried it under three conditions most likely to produce blurry images. First, we shot at a very slow shutter speed in low light. Then, we racked the telephoto lens out to its maximum focal length (the shaky, high-powered binocular analogy). Finally, we shot some extreme close-ups. In each case we got sharp images at slower-than-normal shutter speeds that let us use smaller apertures to better keep both near and far objects in focus. When we shot under the same conditions with the antishake off, most of our images were unusable. Sony also uses this feature to shake dust off the sensor when the camera is powered down.
Sony offers an inexpensive starter lens that we used to shoot most of our
images—a Sony 18mm-to-70mm (27mm-to-105mm in 35mm terms), f/3.5-5.6 lens (with an included sunshade) that has a silky-smooth zoom and is extraordinarily sharp. We also had an opportunity to try Sony’s lightweight 11mm-to-18mm (16.5mm-to-27mm in 35mm terms), f/4.5-5.6 super wide-angle
lens, which gave us visually dramatic pictures with great depth of ? eld. Most Minolta lenses will work, and a line of Zeiss-made digital glass lenses is on the way. The bottom line. When Konica-Minolta decided to ditch its camera business, you could just hear its Maxxum 5D echoing a Brando-esque, “I coulda been a contenda!” With Sony now at ringside, the rejuvenated A100K de? nitely has a shot at the title.—Arthur Bleich
