This telephoto zoom lens is designed with Canon's Optical Image Stabilizer technology while retaining compactness and lightness, in response to demands of photographers. This high zoom ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses), and the image stabilizer effect equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. This new EF-S telephoto lens with great features delivers excellent performance at an affordable price for all photographers.

  • Focal Length & Maximum Aperture: 55-250mm F/4-5.6
  • 12 Elements In 10 Groups, Including One UD-glass Element
  • Focus Adjustment: DC Motor, Gear-driven(front Focusing Design)
  • Closest Focusing Distance: 3.6 Ft./1.1m

A spin Of The Canon PowerShot Sx40 Hs

!±8± A spin Of The Canon PowerShot Sx40 Hs

Looking for a great, high megapixel camera that will meet approximately all of your everyday photography needs? Well, look no further than the Canon PowerShot Sx40 Hs. This camera looks great and you could mistake it for a D-Slr camera. What's actually imaginable about the Sx40 Hs is its long 35x zoom range, coupled with that 12-megapixel camera resolution. Yes, you read that right - a 35x zoom range - which translates to a very fine camera with telephoto reach. Read on and find out more about it.

1. Create and Construction
What does the Sx40 Hs look like? Well, as you can see from the picture, the unit itself is neither covenant nor light. Its dimensions are 3.6 by 4.8 by 4.2 inches (Hwd) and it weighs in at 1.3 pounds. It's competitor, the Nikon Coolpix P500 is slimmer and lighter by comparison.

The Canon PowerShot Sx40 Hs comes with a metal body with a few plastic elements. I like the fact that there's a very deep handgrip which lets you hold the camera firmly. Throw in the Sx40's optical stabilization theory and it means you can get a sharp photo at the greatest end of its zoom range. I tried zooming approximately 35x on the Sx40 Hs, without a tripod or monopod, and my pictures still came out pretty good and sharp.

2. Optics and Resolution
When it comes to long range zoom, very few non-digital Slr type cameras can match the Canon PowerShot Sx40 Hs. The 35x zoom range is great than many digital Slrs qualified with telephoto lenses and is actually one of the selling points of the camera.

With its 12 megapixel resolution, you'd expect that photos taken with the Sx40 Hs to be exceptionally sharp. Incidentally, I got to know about the Imatest software suite - which can be used to part cameras' performance in terms of image sharpness and noise. So here's what I did - to rate sharpness, I shot some photos of a test chart and analyzed them using a center-weighted algorithm. The Sx40 Hs averaged 1,836 lines per photo height, which surpasses the 1,800-line benchmark that qualifies an image as being acceptably sharp.

I've tried many cameras in the past, including the Kodak EasyShare Max Z990 which packs a 30x zoom lens, records a slightly higher 1,946 lines. So in terms of image sharpness, the Sx40 Hs is not the best - but I think its other features more than make up for that.

3. User Controls
Many cameras have very obscure or weird operate placements. The Canon PowerShot Sx40 Hs doesn't have this problem. There are ample operate buttons on the Sx40's body - a top-mounted dial lets you change in the middle of shooting modes, and there's a neat rear four-way jog wheel to scroll through menus, adjust Iso, set exposure compensation, initiate the self-timer, and so forth.

The Canon designers obviously got the Create of the menu theory correct. In fact, the Canon Sx40 Hs menu theory is one of the best I've seen around - comparable even to the top end Dslr cameras. You can swiftly passage most of the base controls you'd encounter in a digital camera, without having to click all around menu after menu. I also like the fact that the Sx40's pop-up flash is manually operated. All I need to do is flip it up when you'd like to use it. Enthusiasts who want a great flash can fit in units like the Canon Speedlite flash, using the dedicated hot shoe.

4. Battery Life
The Canon PowerShot Sx40 boasts a very good and long lasting battery life. I could be outdoors shooting photos like no one's company and the battery would still be Ok. This contrasts strongly to some of the older Canon cameras I have, where the battery just dies on you when you're lining up for a very foremost shot.

5. Warehouse and Transfer
Ok, the Canon PowerShot Sx40 Hs supports all manner of media cards - accumulate Digital, accumulate Digital High Capacity and accumulate Digital Extended Capacity. The camera records 1080p24 QuickTime video - which in my opinion, looks quite good. To copy photos and video into your Pc, you can plug the camera into your computer via mini Usb to copy the files. Alternatively, you can associate the camera to an Hdtv via mini Hdmi. My house loves to do that - plug a digital camera to a huge Tv and enjoy the photos and video.

6. Shortcomings
I feel that the Canon PowerShot Sx40 Hs is a great camera - but it falls short in a few areas. For one thing, the camera isn't cheap! And although it has a fine 35x zoom lenses, I could tell that it's performance in low light is not so good - especially compared to its competitors like the Nikon Coolpix P500, which captures clean images in as dinky as one quarter the light as the Sx40.

Conclusion
All in all, the Canon PowerShot Sx40 Hs is a great camera with a fine 35x zoom range. It has a host of innovative features which allow you to take photo after photo with ease. The quality of the photo shots are way above median and is actually one of the great digital cameras in its class. Do check it out!
