Conclusion: Overall, the Canon 7D should be considered, pound for pound and value for money, one of the best DSLR’s on the market. Combining such a high-resolution with a frame-rate action photographers would die for, all without compromising its low-light performance, to any noticeable degree, is a major achievement.
Excerpt: Trying Canon's new EOS 7D ($1,700, street, body only; $1,900 with 28-135mm f/3.5-5.6 Canon EF-S IS lens) in a preproduction version, I could see that the DSLR wars are escalating again. Not that the conflict hasn't been ongoing-Nikon has targeted Canon head-on with its innovative and powerful DSLRs, plus key reinforcements to its lens line. But with the 7D, Canon is taking aim directly at Nikon's new D300s.
Conclusion: If you expect a huge difference in overall image quality between the EOS 40D, EOS 50D and EOS 7D, you’d probably be somewhat disappointed, but that’s not what the EOS 7D is really about. In terms of ergonomics and features, the 7D is clearly ahead of the other EOS crop sensor cameras.
Summary: If you can justify the price tag it's hard to fault Canon's new APS-C flagship. With class-leading image quality, fast operation and excellent handling the EOS 7D is everything a semi-pro model should be--and the excellent movie mode will be a welcome bonus to those that like their pictures to move. Arguably the best APS-C SLR on the market today.
Pros: Class-leading detail and resolution at base ISO, good per-pixel sharpness, Very good low-light performance, low noise levels and good retention of detail, 8 frames per second continuous shooting speed, Thanks to Dual Digic 4 processors very quick and responsive performance, Excellent build quality with magnesium body and environmental sealing, Good ergonomics, well shaped and comfortable hand grip, Improved button and control layout over 50D/5D Mark II, Highly customi...
Cons: Unreliable white balance under artificial lighting, Slight tendency to overexpose in contrasty conditions, Occasional jagged lines in 720p video, No built-in AF illuminator
Excerpt: News that Canon would be making a direct competitor to Nikon's APS-C workhorse, the D300s ($1,600, street, body only) made many Canonites optimistic. Optimism became excitement with the unveiling of the EOS 7D ($1,700 street, body only; $1,900 with 28-135mm f/3.5-5.6 IS USM lens). Its impressive specs include 18MP resolution, a 100-percent accurate viewfinder, sensitivity up to ISO 12,800, blazing burst rate, and-a first for Canon-built-in wireless flash control.
Conclusion: The Canon EOS 7D is one of the best midrange D-SLRs money can buy. But if you don't need comprehensive video recording features or ultra-high-resolution images, there are a handful of competing D-SLRs that produce comparable image quality for half the price.
Pros: Excellent still-image and HD-video quality. Fast performance. Various HD video recording options.
Cons: Pricey. Video recording is not as simple as with a dedicated camcorder.
Conclusion: The Canon EOS 7D camera body performed superbly and made taking photographs in challenging conditions a breeze. Now I know my photos aren’t great but I feel the 7D actually increased my confidence and resulted in me taking photographs I would not have attempted with a lesser Camera. some of this may well have been due to the well-matched EFS 15-88mm lens whose uncanny stabilization enabled hand-held shots of night scenes, views from moving vehicles and long exposures.
