Canon PowerShot G12 Review

Revision based on a production EOS-G12This is the last in our series of ' Quick ' Reviews. We use this format for the cameras that are functionally similar and identical in terms of output in templates that we have already reviewed. We test to confirm the quality of the image is identical (noise testing and shots of our ' than ' scene study at all), then focus the review about the differences between the two cameras. Learn all about the camera you are interested in we recommend reading not only the rapid, but also the full review of the Canon Powershot G11.Canon Powershot G series has a bold market high-end compact camera. Originally designed to provide users of film SLR ladder (relatively) affordable in passionate about digital imaging, in the last ten years have evolved to become what they are now-suction compact cameras and high-quality, attractive bodies according to existing DSLR users, fitting in ' mainstream ' niche between offers compact and small DSLRS cameras G series.

As can be seen in our recent group test high-end compact camera, the competition in this market segment is fierce. But not only the Canon Powershot G12 have faced this crop's latest compact cameras, also deals with fierce competition from a completely new category-mirrorless interchangeable lens cameras. In recent months, Panasonic, Olympus, Sony and Samsung have started attacking the high-end compact aggressively market with high quality, but very small cameras with larger sensors (APS-C or four thirds). A camera like the Olympus pen and recently inaugurated-PL 2 with its collapsible zoom kit 14-42 mm isn't much bigger (and more expensive) than the G12 and it has a four thirds sensor considerably larger (over 5 x the light-gathering area).

Together with the Nikon Coolpix, Canon Powershot P7000 G12 is the largest "traditional" (i.e. fixed lens, small sensor) compact camera currently available. Is the comfort of its 28-140 mm (equivalent) embedded, zoom and articulated LCD enough to make it stand out from today's crop of compact cameras and mirrorless interchangeable lens? Read our quick review to find out. The G12 is very similar to its predecessor, the G11, in terms of specifications, but Canon has made some significant improvements. Here is a list of the main differences: check the ISO slightly lighter (4 g) higher resolution video mode (720 p up to VGA) up to 12800 ISO expansion (2 .5MP) in 1/3 EV stepsNew front control dial (similar to that found on the EOS DSLR) greater choice of appearance ratiosHybrid IS modeHDR modeElectronic spirit levelTracking AF mode Video mode • MOV [h.264 + Linear PCM (stereo)]:

Canon EOS 60 d Review

Review based on a production Canon EOS 60D

Canon's X0D series has throughout its life appealed to a wide range of photographers, from enthusiasts and semi-pros through to some pros who appreciated having a lightweight option. Each model offered a high enough specification (usually in terms of build quality and AF sophistication) to ensure it was both aspirational and attainable for users who had out-grown their Rebel/XX0D series. However, the feature set always left a sizeable gap below the company's full-blown 'pro' models.

The arrival of the EOS 7D, with its highly configurable 19-point AF system and 8 frames per second continuous shooting capability changed much of this - here was a 'mini 1D' that drew the attention of many people who previously would have been X0D customers. However, the price tag (a 30% premium over the 50D at launch) pushed it beyond the reach of most people who weren't making at least a bit of money from their photography.

The 50D (and by extension the X0D range) was starting to look somewhat redundant: expensive (and in some ways outdated) compared to the rebel T2i (EOS 550D), underpowered compared to the EOS 7D. It seemed obvious that Canon needed something to balance out the EOS range to fill the big gap between the Rebel and the 7D. And so we have this, the EOS 60D.

With the 60D Canon has unashamedly moved the X0D range out of the 'semi pro' bracket and instead focused on the enthusiast photographer looking to upgrade from their Rebel. As a result, it's not the obvious continuation of the 30D - 40D - 50D pattern that its naming might suggest. Instead it sits pretty well precisely in the same market position as was once-upon-a-time occupied by the 'Elan' series of 35mm film SLRs (which in Europe were not-so-coincidentally given double-digit model numbers).

So gone is the magnesium alloy construction that featured in previous models, replaced by a lighter weight plastic shell. Naturally the 60D gains some key 'step up' features from the Rebel line (top panel LCD, rear control dial, higher burst rate), including a few that have trickled down from the EOS 7D. There's also a video- (and tripod-) friendly 3:2 ratio articulated LCD. In imaging terms it brings the EOS mid-range in line with those above and below by upping the sensor resolution to around 18MP and adding full HD movie capture.

The EOS 60D also gains a couple of brand-new features of its own. There's now a wide range of color variations (or 'Ambiences') which can be applied to the image when using the scene modes, and whose effect can be previewed on screen in Live View. The 60D also finally gains the ability to convert raw files to jpeg in-camera, including the option to correct for lens aberrations including distortion and chromatic aberration. As an added bonus, you can retrospectively apply new 'Creative Filters' to files you've shot, including 'Grainy Black and White' and 'Toy Camera' looks.

And so, from a spec and feature point of view, the EOS 60D sits almost exactly half-way between the EOS 550D and the EOS 7D, with a few new tricks of its own. Which, we think, is exactly where it should be (regardless of the inevitable howls of protest at the apparent 'dumbing down' of the venerable X0D line).

Placing the 50D alongside the 60D it becomes clear that the new camera is not a simply a direct upgrade but a repositioned model. The most obvious difference is that it's smaller and, of course, no longer features a metal body.

The 60D is smaller than the 50D but its ergonomics are not substantially changed - it'll still feel like a big improvement over a Rebel series camera, though the loss of the metal body means the same won't be true for 50D owners. One welcome addition is signaled by the little receiver window on the handgrip - the 60D is compatible with Canon's IR remote controls.Higher resolution sensor (17.9MP vs. 15.1MP)Accepts SD, rather than CF memory cardsNo flash sync socketWireless Speedlight controlSupport for optional infra-red remote releaseArticulated 3:2 high resolution LCD screenPlastic body shell (8% weight saving)Standard ISO range extends to 6400, rather than 3200User-definable Auto ISO upper limitHD video recording 1080 p30/25/24 or 720p60/50 plus cropped 640 x 480 movie modeNew features: in-camera raw conversion, ambience settings, creative filters, more JPEG optionsNo joystick, no multi-flash support, simplified top plate & info panel, only one Custom mode, no AF micro-adjustSlightly reduced customization optionsRedesigned control layout with slightly fewer buttonsLower burst rateThe camera handling has become slightly more Rebel-like too: the joystick is replaced by a multicontroller the resides within the rear dial, and several of the direct access buttons have been removed. You do, however, get the all-important second dial on the back, plus an info panel on the top.

As you can see from the table below the 60D is not an unequivocal upgrade from the 50D in the same way that previous cameras in the range have been. Essentially it's a 50D in a smaller body, the includes a flip-out screen and the sensor used in the Rebel T2i (550D) and 7D, with all the HD movie recording capability that brings.

Canon PowerShot SD4000 is (IXUS 300 HS/IXY 30S) Review

The range of SD/IXUS consists of ' style oriented ' of Canon compact cameras, and like the rest of the market is fragmented into many niches, the range has grown to accommodate a growing variety of needs. The SD4000 is on top of current training, offering a 3.8 x wide-angle zoom (despite its Point-and available below) and aperture priority mode. Also the SD4000 is the first of his family to be based on a backlit CMOS sensor that allows high speed modes and promises to improve performance in low light conditions.Style low-key of the SD4000 is belies the fact that it is indeed a very compact camera. In addition to the news on a backlit CMOS sensor, also has a lens that begins with a 28 mm equivalent, F2, 0-impressive, even if it ends in a F5 1.3 rather less worthy of note at the end of its 105 mm equivalent zoom range. We're curious to see the effect of using a CMOS sensor to hand back lit in the SD4000 is, because in our experience the promises made for low-light ability of these sensors (which collect light from what would be the back of a conventional CMOS design and then remove all supporting circuitry from the path of light), are not always evident compared to some of the most modern CCD designs.However, the SD4000 is capitalize read faster than CCDS, CMOS sensor, 720 p HD video offer, 3.7 fps full resolution continuous shooting, image resolution 8.4 fps reduced and even movies that are played 240 fps to 30 fps to give a slow motion effect.

Review based on a production Canon EOS 550D, firmware version 1.0.6

The Canon EOS 550D is a difficult product to categorize. Ostensibly designed to appeal to first-time DSLR buyers and enthusiasts, it offers a lot more technology, and at a higher price, than we might expect for a camera aimed squarely at this sector. Although it might seem logical for the 550D to replace the EOS 500D, the older camera is set to continue in Canon's lineup, which leaves the 550D pinched between its entry-level (represented by the still-current EOS 1000D and the 500D) and nominally enthusiast (the EOS 50D) peers. Confusingly however, apart from build quality (which is all but identical to the EOS 500D), the 550D has more in common with the prosumer EOS 7D, and - perhaps even more confusingly - it out-specifies the EOS 50D in many areas.

Central to the impressive specification of the EOS 550D is a high-spec movie mode which offers full HD capture at up to 30 fps, manual control over exposure, and the option to use an external stereo microphone. The new camera also inherits the EOS 7D's sophisticated metering system (which brings it a lot closer to similarly positioned Nikon SLRs).

So why has Canon apparently risked cannibalizing 7D sales by releasing such a similarly-specced, lower-end model? Well, Canon might have invented the 'entry-level' DSLR way back in 2003 with the attractively priced (for the time) EOS 300D, but these days, this sector of the marketplace is pretty crowded. Far from enjoying a monopoly, Canon, like all manufacturers, faces a stiff battle to make its products stand out amongst their numerous peers. To this end, Canon has pulled out all the stops with the EOS 550D and produced the most highly-specced Rebel we've ever seen. Now that a production sample has arrived in dpreview's offices, we've had the chance to subject it to our full in-depth test procedure. Read on to find out how it performs. * The Canon EOS 1000D represents a sub-class of the Rebel series and hence should be considered a parallel series.

18.7 megapixel CMOS sensor
The 550D uses a new, 18.7 (total) megapixel sensor that's similar, but not exactly the same as the one featured in the 7D (according to our sources at Canon). As before the sensor uses high frequency vibrations to remove dust.

Gapless micro lenses
First touted by Canon on the 50D, the EOS 550D's sensor has what are effectively gapless micro lenses, which significantly increases the efficiency of each pixel.

63-point iFCL metering
The consumer EOS range gets a welcome metering boost with a new 63-zone dual layer iFCL metering sensor (first seen on the EOS 7D). The iFCL system uses focus, color and luminance information to determine consistently exposed shots. All focus points provide distance information to the metering system to determine proximity to the subject and allow the algorithm to weight the exposure accordingly.Typically, metering sensors are more sensitive to red subjects which can lead to overexposure. The EOS 550D combats this with the dual layer sensor, which has one layer sensitive to red and green light and one that is sensitive to blue and green light. The metering algorithm then compares the level of the two layers and adjusts the meter reading accordingly.

Full HD movie mode
In keeping with the overall specification hike the EOS 550D gets full HD (1920 x 1080) movie capture at a range of frame rates (30, 25 and 20), bringing it in line with the EOS 7D. You also get full creative control (over apertures and shutter speeds), and you can set Highlight Tone Priority for movies independently of the setting used for stills. Another welcome addition is the inclusion of a stereo microphone jack.

Screen Color
There are several minor changes to the user interface. You can now preview the color schemes available for the Quick Control Screen.Copyright information
The new in-camera copyright information feature - another that's trickled down from the latest professional models - allows copyright data to be entered directly into the camera, appending that information to each image file in the Exif metadata.

Button changes
The EOS 550D gains new button dedicated to Live View / movie mode; where it used to sit on the EOS 500D is now a new 'Q' button (for fast access to the Quick Control Screen). Most of the buttons have been redesigned, and they're generally larger and flatter.

Canon EOS-1 d Mark IV Review

The Canon EOS 1 D Mark IV is the fifth generation of the speed range of Canon professional DSLRs. It retains the form factor of the original two-handle, 4MP EOS-1 d launched in September 2001 (the same building on integrated grip of film-era EOS-1N RS, also the first to offer 10 fps shooting, albeit without AF between shots). And it is this consistency of design, which extends the model AF and much of the layout of the control, which helps to explain the name-the Mark IV really is the current point in an evolutionary process, rather than a completely separate model.However, 1 D series cameras more than before, the 1 d Mark IV has a lot to prove. Whereas, in the past, Canon's flagship models have been a fairly safe bet, autofocus problems with the 1 d Mark III have cast a shadow over the range. These problems, which appear to come from a combination of manufacturing error, increased complexity of AF customization and the AF sensor occasionally being overwhelmed in bright conditions, have become famous.These issues, combined with the arrival of the Nikon D3 that offered for the first time, an equal level of sophistication of AF, is called into question Canon long-held position as AF front-runner. However, a combination of engineering revisions and user education have meant that many shooters have been able to use the camera without problems-Canon admits there have been problems, but the woes that were so widely reported early in the lifecycle of the camera are still hardly be affecting nearly as many users as might suggest the reputation of the internet.Canon is clearly hoping to dispel the doubts still lingering after the deal III (D) 1 ' by introducing a new AF system. Although the 45 AF points are arranged in a layout that dates back to 1998 's EOS 3, 1 d Mark IV uses a totally new AF sensor with 39 cross-type points that are sensitive to both vertical and horizontal axis. The method of selection of point AF also has been revised for the automatic selection with subject to verification through the new system of IA-Servo II for manual selection.The 1 d Mark IV retains its predecessors 1.3 x Crop, APS-H sensor size, but this time increases its pixel count for a whopping 16MP. This may not seem like many in the era of 25MP full-frame DSLRS and 14MP compacts, but it is much the Mark IV still has the ability to shoot at 10 frames per second. If you consider that this is almost the same resolution as offered by the latest generation of camera Canon targeted study, the 1Ds Mark II, but with the ability to shoot twice as fast, then you start to appreciate what this camera is promising to do.The EOS-1 D Mark IV is the series of 1 D-count of pixels taller, with more than 50% photosites creating a 26% increase in resolution than the previous model. Unfortunately, the release of the EOS-1 d Mark III coincided with one of the busiest periods in dpreview's history (including an office move and studio, staff recruitment, training and more consumer level DSLR launches than ever), this means that even if a lot of work has been done and thousands of sample shots were taken, our review of the camera has never been completed.ModelContinuous high (JPEG) LCD monitor

Canon PowerShot S90 Review

Revision based on a production Canon PowerShot S90The arrival of digital SLRs ' accessible ' saw most manufacturers slowly withdrawn from the market of high end compact camera, but recently the models like the Canon G9/G10/G11 and Panasonic LX3 have shown that there is still the question of pocketable camcorders with real photographic controls. And the Panasonic LX3 is that Canon has in its monuments with the latest in what was, for a long time, that purports to be a dead line of cameras stretching back nearly a decade.

The S90 may not seem like much the S80, S70 and all its predecessors, but was conceived much the same spirit; an alternative smaller, more stylish G-series, offering key features passionate (e.g. acquisition of raw materials and manual checks) in a compact body.

Was already in August of 2005 that Canon has launched the latest in its line of s-series compact cameras photographers ', the S80. And if you can see traces of DNA of S60/S70 S80/S90 in is a very different beast from those cameras; the S90 is smaller, thinner-and in many ways more sophisticated, but lost the optical viewfinder and the lack of something to really get no doubt have an impact on operations.

Perhaps the most striking aspect of the new design is the new control ring built around the lens, which can be set for the control of exposure (i.e., speed, Aperture or shutter), AE compensation, step zoom, manual focus and a selection of other functions. Find a way to offer manual controls can use has proved surprisingly difficult for designers normally brilliant of ultra compact cameras (even if we have suggested a traditional ' opening ' ring like this on many occasions); This addition apparently simple has a transformative effect on the usefulness of extensive manual controls the S90.

As with the Panasonic LX3, Canon has chosen to incorporate a relatively large (1/1.7 "0,43 cm?) CCD sensor, which has been designed with high sensitivity, rather than just higher megapixel count in mind, to maximize the light lens. This 10 megapixel sensor is then coupled with latest Digic 4 processor Canon to offer what the company describes as a dual system.

The picture below should give you a good impression of how the Canon S90 compare size-wise with Panasonic LX3. It is a bit smaller and more like SD/IXUS than the LX3, its simplistic global design makes it visually appealing so refined.
