LAS VEGAS--The heyday of 35mm film SLR cameras is long past, but one foundation of the technology is staging something of a comeback with new help from Sony.

The vast majority of digital single-lens reflex cameras today use an image sensor that's smaller than a full frame of 35mm film, which means lenses behave somewhat differently than on a film camera. For years, only Canon sold SLRs with a full-frame sensor, but Nikon entered the market with its top-end D3 late in 2007. At the Photo Marketing Association trade show Thursday, Sony announced its forthcoming "flagship" Alpha-branded SLR will follow suit. … Read more

As expected, Sony quickly followed its 24-megapixel full-frame sensor announcement by revealing that its previously alluded-to pro model will use the new chip. Since there's a Super SteadyShot housing for the new chip, we can also expect the camera to have in-body image stabilization. The camera is scheduled to "launch" by the end of this year.

Sony also said it will address "the full spectrum" of Alpha products this year, which to me foreshadows a few more product announcements. That's all Sony shared today, but we can expect more details around Photokina this fall. … Read more

LAS VEGAS--Digital SLRs showed strong growth last year, but the sales surge will begin to moderate, according to a new report by the Camera and Imaging Products Association.

SLR cameras are bulky and expensive, yet they're also responsive, work better in dim conditions, and are flexible because photographers can change lenses. Year-over-year sales of digital SLRs grew 42 percent to 7.5 million units worldwide in 2007, CIPA said this week.

By contrast, the SLR growth rate will dip to 22 percent in 2008, 13 percent in 2009, and 9 percent in 2010, the CIPA predicted. That corresponds to … Read more

2/1/2008: Thanks to lack of sleep and rusty HTML skills, the previous table entries for the A700 were incorrect. Sorry for my own addition to the confusion. Fixed now. Lori.

I suppose it was inevitable. With its latest camera announcements, Sony brings its scorched-earth camera marketing philosophy--blanketing each price segment with multiple choices in hopes that one combination of design and features hits pay dirt--to consumer digital SLRs. Today's announcement of the Alpha DSLR-A300 and A350 brings Sony's total number of dSLRs in the $700 to $900 range to three. The models, despite some really nice … Read more

LAS VEGAS--Lenses are as important as camera bodies in the SLR market, and Pentax is trying to keep its customers' appetites whetted by showing off three new lenses still under development at the Photo Marketing Association trade show here.

First up is the smc Pentax-DA*55mm F1.4 SDM, a model with a 55mm fixed focal length and wide f/1.4 aperture for low-light shooting or pictures with soft, undistracting backgrounds. Availability is undetermined so far.

Next is the smc Pentax-DA*60-250mm F4ED SDM, a wide-range telephoto zoom that should be available in the summer.

Third is the smc … Read more

LAS VEGAS--Pentax just announced its new flagship SLR camera, the K20D, but the Japanese company has plans on the drawing board for a higher-end class of camera in 2009.

On the Pentax roadmap for 2009, the SLR quality arrow jumps up "much higher" above the K20D--a bigger step up than the one from the K10D to the K20D--said John Carlson, Pentax's product manager for imaging systems.

"That would be a new category" of SLR for Pentax, he said, but was mum on further details.

Obviously, that statement leaves a lot of room for maneuvering and … Read more

Update 10:07 p.m. PST: I added some further comment from Sunex.

LAS VEGAS--A California company called Sunex wants to make it even easier to photograph your toes inadvertently.

At the Photo Marketing Association trade show here, Sunex plans to show off its new Superfisheye lens whose 5.6mm focal length provide a view encompassing a 185-degree span.

The Superfisheye lens costs $799 for Nikon and Canon SLRs with smaller sensors. It's got a constant f/5.6 aperture. The price includes software to "dewarp" the peculiar fisheye perspective into the rectilinear view humans are more … Read more

LAS VEGAS--You may not know it from the outside, but digital cameras are getting something like an eye transplant.

Deep within every digital camera is a sensor chip whose job it is to capture light. Most camera sensors today use CCD (charge-coupled device) technology, but a newer approach called CMOS (complementary metal oxide semiconductor) is catching on, particularly at the high end of the market.

CMOS advantages can include lower noise, lower power consumption, lower price, and faster response times. In the prestigious and fast-growing digital SLR (single-lens reflex) camera market, Canon and Olympus have used CMOS sensors for years, … Read more

LAS VEGAS--Tamron, one of the larger third-party SLR (single-lens reflex) lens makers, on Monday detailed four new lenses and March launch plans, the week that the Photo Marketing Association trade show begins here. However, the company didn't reveal prices.

For telephoto fans, the company announced its SP AF70-200mm F/2.8 Di. Its close-focus distance of 0.95 meters provides a magnification ratio of 1:3.1 (which means a subject will appear on the image sensor nearly a third the size it does in real life), and it features a constant f/2.8 aperture across its zoom … Read more
