(Editor's note: We stated that the SX7 was the brightest SXGA+ projector available in its price class. The Sony VPL-FE40 matches its stated 4,000 lumen output and is available for roughly the same price, so we have updated the review to reflect that fact. We apologize for the error. -wl)
The last Canon SXGA+ projector we had the pleasure of viewing in our lab was the REALiS SX60 in June of 2006. Now the REALiS SX7 extends Canon's product line in this unique resolution format, which is 1400x1050-or high resolution 4:3. The SX7 has the honor of being one of the only 4,000 lumen SXGA+ projectors under $10,000, and in fact it sells for street prices close to half that much. With a razor-sharp picture, superb color accuracy, an exceptionally bright image, and surprisingly good contrast, the Canon SX7 is a fine choice for photographers, medical educators, engineers, graphic designers, or anyone who requires the display of very high resolution 4:3 images.

The SX7 shares the same case as the other models in the REALiS family, which is three inches longer than it is wide. The lens is mounted off-center on the front of the case, next to a light sensor and a remote IR receiver, while the connection panel and exhaust vent are on opposite side panels.
Canon's marketing literature describes the SX7 as an "Ultra-portable" SXGA+ projector. While that term is a bit of a stretch, the SX7 is in fact one of the lighter SXGA+ projectors available, and it comes with a sturdy carrying case. There are several other SXGA+ projectors which are lighter than the SX7, but they sacrifice anywhere between 500 and 1500 lumens as well as other convenience features in favor of lighter weight.
The 1.7:1 powered zoom/focus lens gives the SX7 the longest zoom range available on a portable SXGA+ projector. The SX7 is easily bright enough to project a 200" diagonal 4:3 image, and it can project an image of that size anywhere from 19' 7" to 32' 6" away from the screen. The best part, though, is that the SX7's lens only loses 22% of its light output when at the maximum telephoto setting, which is outstanding. Often, zoom lenses of this range can curtail lumen output by 35% or more when set to their maximum telephoto positions.
Speaking of brightness, the SX7 is Canon's brightest SXGA+ projector yet released, and it is in fact one of the brightest SXGA+ projectors available under $12,000. The SX7 is rated at 4000 lumens, and our test unit measured a maximum of 3327 lumens. This gives the SX7 the somewhat unique ability to be used in rooms with significant ambient light or on very large screens. If you are into old classic films and want a large scale 4:3 screen to view them in their original aspect ratio, the SX7 is a superb choice for this use. In its optimum video mode it will easily light up a 150" 4:3 screen.
The SX7 has several image modes, labeled Standard, Presentation, Movie&Photo, adobeRGB, and sRGB. Our reading of 3327 lumens was obtained in Presentation mode, high lamp, with the zoom lens at its widest angle position. For situations not requiring so much light output, Standard mode offers a maximum output of 2693 ANSI lumens in high lamp mode or 1946 ANSI in low lamp mode. In all operating modes, the option to use the low lamp setting will cut lumen output by 28%. Movie&Photo mode netted 1220 ANSI lumens as well as increased contrast, and produced a bright, high contrast image that would be best suited to a dark room viewing environment. Our personal favorites were adobeRGB and sRGB, which offered excellent compromises between brightness and color balance. At 1531 and 2706 ANSI lumens respectively, either of these modes would be ideal for material where color accuracy is a priority.
Of course, one of the most important qualities of any high-resolution projector is the sharpness and clarity of the image. The Canon SX7 is sharp as a razor with native 1400x1050 content, which is to be expected. And due to the combination of the SX7's high resolution and the naturally smooth image of LCOS projectors, the SX7 has no visible pixelation, even when standing very close to the screen. But how does it perform with non-native material?
We hooked the SX7 up to a laptop displaying a standard 1024x768 XGA signal. In this configuration, material like PowerPoint slideshows and photography did not suffer one bit. The image on screen appeared smooth, yet detailed. Using graphically challenging PC games, the experience was likewise satisfying, with pixel-perfect accuracy maintained throughout the image.
The SX7 is a true multi-purpose projector. Not only does it deliver sharp data and graphics images, but it did a wonderful job of compressing 1920x1080 video to fit in a 1400x787, 16:9 pixel matrix. The projector did crop the image slightly, losing about 2% of the image from the bottom and 1% from the right side, but this is rarely noticeable outside of a test pattern.
The final test was to play back content from a 4:3 standard definition DVD. With film content, the SX7 produces a smooth image that is a pleasure to watch. There were some artifacts present with video content, including some slight moire patterns in suit jackets and fine textures. However, If you are a fan of old classic films, or watch a lot of TV series on DVD, the SX7 gives an excellent, bright image with lots of snap on a very large screen.
The SX7 is rated at 1000:1 contrast, but it has no auto iris. This means that the 1000:1 figure is native contrast. Despite this rather low contrast rating, Canon SX7 performs much better than one might expect. On a white screen, video material showed good shadow detail and relatively solid blacks. Switching to a gray screen improves black levels and color saturation, and yields a beautiful picture that one would not think possible from a projector rated at 1000:1 contrast. The performance of the SX7 with video is good enough that we have no qualms about recommending it for dedicated use in a large scale 4:3 home theater.
As it stands, the SX7 projects such that 9% of the image's height is actually below the lens's centerline, which limits one's mounting options. The depth of the case requires a deep shelf - at least fourteen inches - for rear shelf mounting. Heat exhausts to the side of the projector, so an extra few inches of side clearance are needed to avoid overheating. Coffee table mounting necessitates tilting the projector upwards to hit the screen, which requires keystone correction to square up the image. A ceiling mount would likely require a drop tube assembly to bring the projector down far enough that the image would hit the screen. While this throw offset may very well be ideal for some people, it will be an inconvenience for others. It is also possible to "ceiling mount" the projector on the underside of a rear shelf, which allows for the conveniences of a rear shelf mount and the benefits of a ceiling mount in the same installation. Be sure that the SX7 has adequate clearances for heat dissipation when using any sort of rear shelf or enclosed installation.
Replacement lamps for the SX7 cost $430, which is typical for this class of projector. However, the SX7's lamp is rated for up to 3,000 hours of operation in low lamp mode, and it can still produce up to 2400 ANSI lumens in this mode.
The SX7 lacks HDMI, but it does include a DVI-I port, and HDMI is not an expected feature on data projectors. It also lacks component video ports, but includes a Component-to-VGA adapter cable. If you wish to connect the SX7 to video sources such as a high definition disc player or HD cable/satellite box, there is an adapter that will allow you to do that.
Finally, the SX7 shows some light spill around the projected image which is especially visible when the projector is displaying a dark image, such as a night-time shot in a movie. During data use, this is not much of a concern, since the screen will most likely be bright throughout your presentation. But when using the SX7 with video or in a home theater setting, it may prove distracting. Counteracting this effect can be as simple as making the projected image slightly larger than the screen so the overspill falls on the screen's frame.
Meet the New Boss
Like the older SX60, the SX7 is designed with two different markets in mind. It is excellent for the display of very high resolution photography, technical schematics, and medical imagery; however, it is also well suited to the display of large scale 4:3 home theater. With the dearth of 4:3 home theater projectors available in today's market, as well as the glut of XGA business projectors that don't give so much as a passing thought to video performance, the SX7 is a unique and welcome addition to the projector world.
The price tag is a bit steep at $6999 MSRP and $5200 street. However, for the money you get one of the finest 4:3 projectors currently manufactured, with the best lumen output available in a consumer model and sharpness and clarity to spare. If you need a bright, high resolution 4:3 projector in a portable package there are relatively few options, and none of these options offer a combination of features quite like the SX7.
As reviewers, it is our job to find fault with the products that cross our test bench. With the Canon REALiS SX7, that is a fairly difficult task. The projector is bright, but brightness can be adjusted easily; it has a long zoom; it has excellent color accuracy and saturation. Contrast is excellent for this class of product, and plenty sufficient for sparkling, dramatic video. For the display of high-resolution data graphics, professional photography, and 4:3 home theater, the SX7 is a powerful performer all around.
