The new top-end model from medium-format camera maker Hasselblad is now on the market, and it's not cheap: the 200-megapixel H4D-200MS will set you back 32,000 euros, or about $45,000.

The camera actually uses a sensor with a mere 50 megapixels, but with Hasselblad's multishot technology combines six shots into one. That means moving subjects such as fashion models need not apply. But a lot of this very high-end photography involves static subjects such as jewelry, watches, cars, and paintings for reproduction.

Hasselblad announced the H4D-200MS last September at the Photokina show. At the time, the … Read more

Today Pentax announced the smc D FA 645 25mm f4 AL SDM AW lens for the 645D digital medium-format SLR camera. This is the second lens in the 645D series, along with the smc D FA 645 55mm f2.8 AL SDM AW lens($1,100). The new D FA 645 25mm f4 is an ultra-wide-angle lens offering the equivalent focal length of 19.5mm in 35mm format terms. When mounted on a 645 film camera the new lens has an equivalent of 15.5mm. This is the widest of all Pentax 645 lenses.

The 25mm 645D lens, along with … Read more

Phase One, the Danish maker of high-end digital camera gear, announced a new top-end product: an image sensor with a whopping 80 megapixels.

The IQ180 is a digital back, which consists of an image sensor, viewing screen, and associated electronics housed in a removable module that fits on the back of a medium-format camera body such those from Phase One-controlled Mamiya. The medium-format market, which consists largely of photographers shooting expensive subjects such as fashion models and jewelry, is a demanding one willing to pay a premium for the very detailed images made possible with medium-format gear. Phase One's … Read more

COLOGNE, Germany--How much room is there in the medium-format digital camera market? Pentax is hoping to find out by elbowing its way in with its 645D.

The company showed off the hefty camera at the Photokina Imaging show here this week. It's been for sale only in Japan so far, but at Photokina, Pentax announced it will go on sale in Europe starting in December.

"The 40-megapixel picture-taking mean machine, [which] delivers unprecedented image quality while offering top end control and user friendly handling, will be spreading its reach beyond Japan to invade European photography," Pentax said in a statement.

When Pentax launched the 645D earlier this year after years of on-again, off-again development, it downplayed its ambitions by saying the camera was chiefly for Japanese landscape photographers who have equipment from Pentax's medium-format 645 film camera days. But the company is taking a new tone with its aggressive statement about geographic expansion. It's also investing in work to ensure Adobe Photoshop and Lightroom can automatically correct Pentax medium-format lens issues, even before more mainstream optics have that support. … Read more

COLOGNE, Germany--For those who find Hasselblad's 60-megapixel H4D-60 camera a little too confining, the company plans to sell a 200-megapixel model in the first quarter of 2011.

The Copenhagen-based medium-format camera maker announced the product today at the Photokina imaging show here. Interestingly, it uses the same camera body as its current H4D-50MS, which will be upgradable, said Peter Stig-Nielsen, director of product development.

However, even in the rarefied air of the medium-format market, where image sensors are very large and very expensive, the 200-megapixel "extended multishot" technology won't appeal to everyone: each shot will take about 30 seconds to capture, restricting the camera to stationary subjects such as cars, watches, and jewelry.

That's because of the design of the Hasselblad multishot-series cameras such as the H4D-50MS. The current model uses tiny piezoelectric motors to shift the sensor a very small amount to combine two shots into one higher-quality image.

"We are now building it into a real product that's going to hit the market in the first quarter of next year," Stig-Nielsen said. "It is going to be an extension of the current H4D-50 multishot."

Most digital cameras capture color with a checkerboard of color filters called a Bayer pattern over image sensor pixels; each pixel captures only red, green, or blue color information. The multishot technology shifts the sensor so the same pixel can capture each of the colors, ridding the camera of the need to mathematically infer the missing values of red, green, and blue. … Read more

Most folks think carefully before spending $300 on a new camera. I'm more serious about photography, but I still swallowed hard before buying an SLR costing about 10 times that.

But brace yourself for even more sticker shock, because there are some professionals who spend more than an order of magnitude beyond what I did. This is the domain of medium-format digital cameras, whose sensors have roughly twice the surface area of a high-end SLR for maximum image quality.

Medium-format gear is beyond my means but not beyond my curiosity, so I was pleased with an offer to try one out. In this case, it was Phase One's top-of-the line products--the 645AF and newer 645DF cameras, the P65+ image sensor back that can be attached, and a handful of lenses.

Such gear appeals chiefly to fashion and commercial photographers, the types who produce full-page ads of glamorous models and diamond-encrusted watches. Lacking the gaggle of assistants, spacious studio, and forest of flash equipment common in this realm, I'm not equipped to put a modern medium-format camera through its full paces. But I'm not a bad or inexperienced photographer, so for those who've wondered what a medium-format machine is like, here are my impressions.

So what do I think of a camera with this price tag? … Read more

The medium-format market is mostly an obscure niche of the digital-camera industry. Prices are high, customers must have lavish budgets, and optics and sensor technology is different from the SLR realm.

Heck, most people hadn't heard of the brand names involved. Until now: This time it's Pentax that announced its entry into the market with a product called the 645D.

It's not going to rewrite the rules of photography. It'll be available only in Japan, at least for starters when it ships in May, it needs its own lenses, and it costs 850,000 yen--about $9,200. But there are enough interesting developments here that it's worth noting.

Medium-format cameras have been niche items for years, distinguished from SLRs chiefly by their larger of a film frame. Now that digital sensors are in and film is out, though, the comparative costs of medium-format cameras have surged, because making a large sensor is a lot more expensive than making a smaller one. Pentax's model uses a 40-megapixel Kodak sensor measuring 44x33mm, larger than a "full-frame" SLR that uses the 36x24mm frame size of 35mm film and a lot larger than the sensors in mainstream digital SLRs.

To go a bit beyond the press release, I recommend reading Luminous Landscape's interview with Pentax's Yasuyuki Maekawa about the 645D. It triggered a number of thoughts about medium format and Pentax's effort. … Read more

Epson is replacing its Stylus Pro 3800 medium format (17x22) printer with the 3880, rolling its latest set of technologies down the product line from the Stylus Pro 4880, as well as introducing a new version of its screening architecture.

The 3880 is getting the 8-color UltraChrome K3 Vivid Magenta ink set that's already been incorporated in most of Epson's other pro graphics printers, plus the same ink-repellent coating on the printhead to minimize nozzle blockages. With this model, Epson introduces Accuphoto HD2, an update to its screening technology with look-up tables co-developed with RIT; the new LUTs … Read more

A new tremor on Thursday traversed a photography world already shaken up by the arrival of digital technology as Phase One, a Copenhagen-based company that caters to professional photographers, announced a plan to acquire some high-end photography assets from Eastman Kodak.

To nobody's surprise, Kodak wound down its 35mm Kodachrome film product on Monday. In the rarefied realm of medium-format photography, where film sizes are much larger, and the demand for quality is much higher, the change to the digital era has been equally jarring.

Phase One, though, was digital from the outset, and it's become a force … Read more
