But for the enthusiast who wants a smaller alternative to the bulky but high-performance SLR, or single-lens reflex, camera, it's slim pickings.
"There's a gap in the market for a certain class of camera for somebody who's got a digital SLR and wants those capabilities at the times they're not carrying an SLR," said Lyra Research analyst Steve Hoffenberg.
Digital SLRs bring a host of improvements over compact cameras: they start up faster, shoot more frames per second, produce "raw" images that retain all the data from the image sensor, offer manual control over numerous settings, and have large sensors that work better in dim light or when trying to freeze action. The SLR market is fast-growing and today dominated by Canon and Nikon, but also has contenders in Olympus, Pentax, Panasonic, Sony and others.
But SLRs are too bulky for a purse or pocket. Even serious shutterbugs often leave them behind when scaling mountain peaks, traveling or just heading to work.
"I like photography, but it's a passion, not a job. I like first of all to take my camera with me always, even if I'm (on) my bicycle," said Stefano Di Cecio, who lives in Italy's Tuscany region. But he's used film SLRs, and he wants raw image support, manual controls and a good lens, so he settled on the Panasonic DMC-LX2.
A pie-in-the-sky compact camera would have a fast, high-quality lens that reaches as wide as 28mm. It would have a large sensor that emphasizes sensitivity over megapixels. Raw image support so the photographer gets more than just stripped-down JPEGs. An optical viewfinder for shooting in bright conditions or preserving battery life. A quick shutter response. Maybe a hot shoe to accommodate an external flash. And a price tag under $500.
That's probably too big an engineering challenge for a single model. But some camera makers have come close.
Some options
Possibly the compact camera closest in design to an SLR is Canon's PowerShot G7, the latest in a series of products aimed directly for the SLR enthusiast. A Tokyo resident whose Flickr username is Leopard Gecko uses his to shoot close-ups of insects and flowers--but like many camera reviewers, he wishes it came with the raw image support that predecessors like the G6 had.
Another option is the Nikon Coolpix P5000, which is considerably smaller than the PowerShot G7 but, like it, has a "hot shoe" to mount an external flash. However, it too lacks raw support.
Bulkier models such as Olympus' SP-550 UZ and Fujifilm's Finepix S6000fd have long zoom ranges and raw-image support, but they're not so easily to place in a pocket, and long zoom ranges typically take a toll on image quality. Ricoh's GX100, which supports raw files but is compact, has won some ardent supporters but isn't widely available in the United States. And Sigma's forthcoming DP1 uses the same higher-end Foveon image sensor as its big brother, the SD14 SLR, but the compact model has a fixed 28mm focal length lens.
Some experts have called for a better compact camera--Mike Johnston of the Online Photographer blog has called it the "decisive moment digicam," and Thom Hogan, author of the Nikon DSLR Report, has described in detail his ideal small camera with a large sensor.
Hogan estimates hundreds of thousands to millions of such a camera could be sold annually. That may sound small, but it's likely to be a nice niche, he said.
"Digital SLR growth is hitting the plateau already and will level off to normal or worse within the next year or two. Meanwhile, there are unserved niches where you could make your own growth, get almost the same unit volume and retain high product margins," he said. "High-quality compacts is one of them."
But there's a good reason manufacturers might pause before aiming a compact camera at SLR aficionados, Hoffenberg said: they probably already have one, even if it's not necessarily high-end.
"Lyra's research shows the vast majority of digital SLR owners already owned a point-and-shoot digital camera before they purchased an SLR," Hoffenberg said. "Just about half of digital SLR owners had multiple point-and-shoot cameras in the household--two or more."
Enough megapixels already
Some believe a step in the right direction would be to use larger image sensors--perhaps even as large as those in lower-end SLRs--or at least sensors with more sensitive pixels. The race to squeeze as many pixels as possible onto sensors has increased unwanted colored speckles called image "noise," several experts contend.
Stefano Mattia, who lives in Rome, is happy with his Panasonic DMC-LX2--except for the sensor.
"Take the LX2 and replace its sensor with one which could provide virtually noise-free pictures up to ISO 400 to 800, and that would be the perfect compact camera," Mattia said. "I'd rather have fewer megapixels than noisy photos."
Fewer megapixels also would reduce some burdens of processing and saving images, potentially improving responsiveness. But consumers would have to understand the argument that a particular camera makes up in quality what it lacks in quantity, and that could be tough, judging by the unceasing increase in sensor megapixel counts.
Enthusiasts frustrated with higher-end compact cameras have grounds for hope that camera makers will better meet their needs, though.
"What Nikon saw with the P5000 and Canon with the G7 is that particular niche does now appear to be growing big enough that it can support some models in the market," Hoffenberg said.

"... a step in the right direction would be to use larger image sensors..."
This should be at the top of the story. Image sensor size ( and I might add
lens quality) are more important than megapixels.
When does a 6 megapixel camera give you better pictures than a 10 megapixel
camera? When that 6 has a image sensor twice a big as the 10.
Do a Google search on "camera image sensor size" one search result Photo.
net has some great information.

somebody will launch just such a camera. Manual controls, RAW

yes, yes, yes!
I do carry a small sub compact everywhere I go, but it lacks a lot of features I desire.
There is a large market for a pro compact camera, are you listening,Canon,Nikon,Sony, Panasonic, Pentax etc?
But I think there are flaws with the argument. For one thing, the biggest SLR makers, Canon and Nikon, both sell advanced compact cameras with some SLR features, even if they're not going enough far enough for some buyers' liking. And some other camera makers don't have an SLR business to protect in the first place. Finally, a lot of entry-level SLR buyers--one part of the market for high-end compact cameras--will never use anything more than the low-end "kit" lens that comes with an SLR and therefore aren't good candidates for a lens-body ecosystem lock-in. And of course, physically, it's just a huge engineering challenge squeeze include large sensors and large (high-speed) lenses into compact bodies and still have a reasonable price tag.
end Panasonics. Yes, they are feature laden, but because of the
poor quality image sensor and ultra high levels of noise, the
images produced are practically useless. Also RAW image files
are overrated. Any decent professional photogapher chooses
cameras, sensitivity and exposure for ideal image capture which,
in most cases eliminates the need to fix it with the RAW image
converter. Digital work flow is about streamlining the process,
not adding more steps.
Canon makes great hardware, bur the skin tone reproduction
through the entire line from compact to hind end D-SLR is awful.
Take a look at the lack of high ISO noise and fantastic skin tone
reproduction found in the Fuji S3 and S5 as well as F31 and
9500.
Photography is about creating images not pressing buttons and
playing with gadgets. Image quality is the ultimate goal. For
some reason CNET editors just don't get it. It's always a
discussion of features and specs. I'm guessing that there isn't a
single professional photographer on the staff.
Fundamentally, the reason I wrote this story is because I've encountered many people want on their compact cameras what they have or can get with SLRs. Call the SLRs' advantages "features" or call them "quality," but that's what a lot of people are looking for.
And while streamlining workflow is important for a lot of folks, myself included, there certainly are a lot of people who actually enjoy messing around with their shots, much as some photographers enjoy messing around in the darkroom. Raw images are more amenable to the tinkerer. When I'm on a deadline, though, I shoot JPEG.
Also, CNET does have professional photographers on staff, including myself to a limited extent.
shutter lag too long.
If you want compact, get a compact and the little screw-on adapters.
Of course there could be another scenario if Canon comes up with a better sensor and won't try to sqeeze some 16M pixels into it. Very unlikely :)
Decent lens + decent sensor + sensible megapixel + RAW = I'm sold!
By sensible I mean no budget 10MP jobs where you end up with large average-quality photos that takes a lot of processing time by the camera and memory on your card. Drop the MP and up the quality! Will end up with better photos and I'd be able to shoot more than one photo every 8 seconds ;)
Sorry, but physics (diffraction, in this case) is going to win the battle.
There is a new challenge with digital cameras, though: film responded to light no matter what direction it came from, but digital image sensors respond best when the light arrives perpendicularly. That imposes new optical constraints on lensmakers. On the flip side, film cameras had to direct light onto a 36x24mm patch of film, which requires larger lenses than for the much smaller sensors in compact cameras.

Compact film cameras like the inexpensive Olympus Stylus Epic or the posh Contax T3 are very compact, while having top-notch optics that are equal to any film SLR lens.
Sigma has realized the potential of this niche and announced the DP1 (www.sigmadp1.com), a relatively compact camera with a 28mm f/4 (35mm equivalent) lens and an APS-C size sensor using Foveon X3 technology that offers true colors instead of Bayer interpolation. I would have preferred a more compact ans faster 35mm f/2.8 (50mm equivalent) lens like the one on the fixed-focal film compacts, but at least they are trying.
Unfortunately, the pricing on the DP1 still hasn't been announced and it seems to be late.
Don't expect Canon or Nikon to lead here. Most of the innovation in digicams has been coming from smaller players, e.g. Olympus' ultrasonic dust-removal mechanism or Minolta's in-camera anti-shake.
When I lost my F30, I replaced it with a F31fd rather than a F40fd, even though I despise the proprietary xD card format, but so I can keep acceptable low-light performance.
camera. The megapixel race is nothing more than a marketing
gimmick. It's too bad because Fuji had real winners in the F10,
F11, F30 and F31 cameras, especially in the area of high ISO and
low noise (that's a tough combination in a high resolution small
sensor) Referring to my comment above so many people forget
that the whole point of photography is making images and not just
pressing more buttons or wearing the latest gadget around your
neck.
I can only take pics at ISO 80 or 100, still has some noise.
I have to clean it up with noise ninja.
pro) and I completely agree that the high-end compact market is
being under-served by manufacturers who make excuses in the
vain hope that what they're offering is what we want. Maybe
what "most" of the market wants, but not what we'd buy.
The few who seem to be on the way to "getting it" still aren't
there yet: The vapor-ware Sigma DP1 has a slow lens, the Ricoh
GX100 has slow RAW and a small sensor, and the lovely+pricy
Leica M8 is still a rangefinder - one step away from digital
perfection.
Mike Johnston's DMD (decisive moment digital) concept is the
closest I've seen to the type of compact camera that we'd have
no qualms about buying. There is a pent-up market for such a
thing. We've definitely limited our digital camera purchases for
want of the right features. $500 for something half-baked is
too much, while $1000 for the ideal compact camera is a steal.
The one modification to the DMD I'd offer is that a good, built-in
digital viewfinder would be preferable to a purely optical one. It
still must be a viewfinder, not just an external LCD (a camera is
first and foremost an extension of the eye, not of the hand).
Rangefinder games are no longer needed in order to get the
benefits associated with the word "rangefinder".
- Pixels vs Sensitivity
- by One-Eared Gundark July 20, 2007 1:58 PM PDT
- The sales people at the big box stores push camera sales based on megapixels. Customers hear how more pixels will give them a better picture, yada yada yada, and believe it. The sales people probably even believe it.

Showing 1 of 2 pages (42 Comments)The public needs to be aware that 300 dpi will produce photos that will satisfy most people (not for pro work, of course). That means for a 4"x6" image, you only need 3 megapixels to produce a good print. The public needs to be more aware that sensitivity and noise is more important than pixel count.
Take the 300 dpi rule and apply it to the largest physical prints you plan to make. That should tell you how many megapixels you NEED. If that need approaches 12 megapixels, you need a medium-format camera with a much larger sensor. Prepare to spend some serious dough, though...and you better start making some money with your prints!
