From a distance, could the 12 megapixel Canon PowerShot SX40 HS ($ 429.99 direct) may be confused with a D-SLR camera. His black body, big goal, the bump handle deep and the top is the signature function of SLR like the Canon EOS Rebel T3i equity ($ 899.99, 3.5 stars). The objective SX40 does not come out yet, and its large size is due to a long 35x zoom range, one that is unmatched by any existing SLR. You can not drop it in your pocket, such as publishers 18x zoom 'Choice Nikon Coolpix S9100 ($ 329.95, 4 stars), but it's a small price to pay for a 840mm (35mm equivalent) telephoto reach.
The design and development
The SLR-inspired SX40 HS is either compact or light. It measures 3.6 by 4.8 by 4.2 inches (DRC) and tips the scales at 21.2 ounces, or about 1.3 pounds. Nikon Coolpix P500 similar style ($ 399.95, 4 stars) is thinner and lighter, measuring 2.3 by 4.1 by 1.3 inches and weighs 1.1 pounds, with a broad slightly from 22.5 810mm (equivalent to 35mm) 36x zoom. The SX40 35x lens is not as wide and 24 mm at the short, but it extends to 840mm to give you a little more reach on the long end, while maintaining a wide angle. Stepping away from these figures, there is not much practical difference between the two, you can take some steps forward or backward for the difference in both ends and the 12-megapixel resolution gives you some room to trim without sacrificing picture quality for online sharing, or a standard size poster.
The camera has a metal body width, with some plastic parts. A handful of depth allows you to maintain firmly the SX40, and 230k dot LCD is 2.7 inches in size and articulated so you can see from all angles. Also 230,000 dot electronic viewfinder, but its small size makes it difficult to see details of its framework. Makes it very useful, as you can hold the camera against your body reinforcement and using the viewfinder instead of holding it at arm's length and use the rear LCD to frame your photos. This, along with optical stabilization system SX40, you can get a clear picture at the end of its zoom range, even if you do not have a tripod or monopod.
There is a large control buttons on the body of the SX40, as well as a D-SLR. An assembly line top lets you switch between shooting modes, and the wheel in the back of four channels are used to navigate menus, adjust the ISO, exposure compensation system, activate the timer, and switch between development. The menu system is one of the highlights of the device, because orders are placed logically for quick adjustments. The SX40 is pop-up flash is manually operated and return it when you want to use. You can also use a Canon Speedlite flash, thanks to the dedicated hot shoe.
Performance and conclusions
The HS SX40 does not boast the fastest start in the world, taking about 2.5 seconds to catch the first time. After that, it gives a very impressive time of 0.4 seconds to recycle 0.5 seconds and shutter speed. It does not start as fast as Nikon S9100, ready to shoot in 1.6 seconds, but it does better is the shooting of a sudden long the Nikon requires 1.6 seconds between shots and its right on the speed shutter. Nikon P500 takes 2 seconds to start, but needs 1.5 seconds between shots. Rafale is excellent, capturing just over two frames per second.
Package used Imatest to measure the performance of the cameras "in terms of sharpness and noise. To assess sharpness, I shot several pictures of a test card and analyzed using a compensation algorithm in the center. The SH average SX40 1836 lines per picture height, which exceeds the 1800 baseline, which qualifies as a strong image acceptable. Although this is a good result, the camera is not the sharpest in its class; Kodak EasyShare Z990 Max ($ 329.95, 3 stars), which has a 30x zoom, has a slightly higher 1946 lines.
Noise is also a factor in image quality. When an image contains more than 1.5 percent of the noise it looks too grainy. The HS SX40 was able to stay below this threshold with 800 ISO, so you can take good pictures in moderately lit environments. Nikon P500 up better here, to keep noise below 1.5 percent by using the ISO 3200, which is four times more sensitive to light as ISO 800
The camera records QuickTime video 1080p24, and the artwork looks pretty good. Detail is maintained, but there are some flaws in the video when panning, the effect is probably due to the blinds. These defects, which causes part of the video does not seem to be in line with other rarely, and only when the pot. You can connect the camera to your computer via mini USB to copy video and images to your hard drive, or an HDTV via an HDMI mini to see them comfortably favorite chair. Standard SD card slot supports SDHC and SDXC card formats.
The Canon PowerShot SX40 SA capture sharp, offers a stellar performance continuous frames, and offers a longer zoom in its class. The continued rapid fire, combined with long-range telephoto, this camera makes a good catch of sports and wildlife. The camera is not cheap, so you might consider General Electric X500 ($ 149.99, 3.5 stars), which offers a 15x zoom, but it is best to use a bright light only. If low-light shooting is more important than rapid image capture, you should take a look at the Nikon Coolpix P500, which captures clear images in just one quarter of the light as the SX40, but some sacrifices the telephoto end teensy . While the editors of our decisions "in this category is always the pocket, 18x zoom Nikon Coolpix S9100, the Canon SX40 PoweShot SA is also a very nice camera, with a much longer range.
