Many new camera models are on display at the Photo Marketing Association International (PMA 2005) show.

Standing out among the competition are are compact, point-and-shoot digicams cameras that pack at least 7 megapixels of image resolution.

These aren't the first models of the type - for example, the Olympus C-7000 Zoom and Pentax's Optio 750Z have been around for awhile. But most of the new cameras are more truly pocketable, making them easier to take anywhere. And with prices as low as $360, they are mainstream products that will appeal to buyers who would have opted for a 5-megapixel model until now.

Lower-resolution cameras still deliver sufficient resolution for attractive prints, even at sizes of 8-x-10 inches and larger. But if you're a serious shutterbug, 7 megapixels provide more control over your photographic results, since you can crop shots more extensively without compromising image quality.

Here are some highlights of new models being shown at PMA 2005, the Photo Marketing Association International event. All of these cameras are scheduled to become available in the US in March, except for the Samsung V70 and V700, which are available now, and Nikon's 7900, which the company says will ship in April.

Camera Parade

Canon PowerShot SD500 Digital Elph: At $500, the 7.1-megapixel Elph is the priciest of these new cameras. But it also makes the most striking first impression. It's not as svelte as some Elphs (including the SD400, a new 5-megapixel model), but it's still amazingly sleek for a 7-megapixel model. Like other Elphs, it's got an elegant metal case, and Canon has given the SD500 somewhat curvier styling than previous models. Its new features include a clever option that automatically rouses the camera from sleep mode when you pick it up. The SD500 has a 3X optical zoom and a 2-inch LCD (two features it shares with most of the other new 7-megapixel models).

Casio Exilim EX-Z750: The $450 EX-Z750 looks a lot like other Exilim "Card" models - which means it's extremely thin and eminently pocketable. It ups the ante on most of the models here in two ways: Its 7.2-megapixel resolution is a bit higher than most, and the camera has an oversized 2.5-inch LCD rather than a more typical 2-inch display. It also comes with a docking station for easy recharging and TV output.

Nikon Coolpix 7600 and 7900: Nikon introduced two 7.1-megapixel models, both of them in the company's familiar compact form factor with a prominent grip so you can easily grasp the camera. The $380 7600 has Nikon's red-eye fixing technology, as well as D-Lighting (which aims to correct pictures in which backlighting results in underexposed subjects) and the aptly-named Blur Warning. The $450 7900 has a more upscale metal case and some additional features, including one that identifies faces as you're framing a shot and then locks in on them, so they stay in focus even if the subject bobs and weaves before you take the picture.

Samsung Digimax A7, V70, and V700: Samsung still isn't one of the first companies that come to mind when you think of digital cameras, but it's a major presence at this year's PMA, and it's demonstrating no fewer than three competitively-priced seven-megapixel models. The A7 is the entry level model; it's not particularly svelte, but at $360, it's the least expensive model here. The $400 V70 ups the ante with an aluminum case and the only LCD here that swivels out from the case. And the $410 V700 has a smaller, swoopier case design and comes in three evocatively-named colours: noble wine, indigo blue, and milk silver.

Sony Cyber-shot DSC-W7: This new model in Sony's W line is a higher-end cousin to the DSC-W1, a top performer in PC World's reviews of point-and-shoot cameras. The $450, brick-shaped DSC-W7 is a bit chunkier than some of the new models; it looks like a thicker version of Casio's Exilim and shares some features, including 7.2-megapixel resolution and a big 2.5-inch LCD. As with other Cyber-shot models, Sony boasts of fast response times; the vendor says the DSC-W7 can take full-resolution pictures at just over one-second intervals.

Keep Your Eye on the Lens

Seven megapixels may be the top of the line for point-and-shoot cameras at the moment. But it won't stay that way forever: Concord representatives are talking about an 8-megapixel camera the company plans to ship late this year for $250. Better-known manufacturers are unlikely to meet that price point, but you can bet that Concord's EasyShot 820Z won't be the only consumer-priced, 8-megapixel compact camera out there.
