A Review Of The Canon PowerShot SX40 HS
Posted November 1st, 2011
Looking for a great, high megapixel camera that will meet practically 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 really incredible 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 powerful camera with telephoto reach. Read on and find out more about it. 1. Design and Construction 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 system and it means you can get a sharp photo at the extreme end of its zoom range. I tried zooming almost 35x on the SX40 HS, without a tripod or monopod, and my pictures still came out pretty good and sharp. 2. Optics and Resolution 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 measure cameras’ performance in terms of image sharpness and noise. So here’s what I did - to evaluate sharpness, I shot several photos of a test chart and analyzed them using a center-weighted algorithm. The SX40 HS averaged 1,836 lines per picture 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 The Canon designers obviously got the design of the menu system correct. In fact, the Canon SX40 HS menu system is one of the best I’ve seen around - comparable even to the top end DSLR cameras. You can quickly access most of the common 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 better flash can fit in units like the Canon Speedlite flash, using the dedicated hot shoe. 4. Battery Life 5. Storage and Transfer 6. Shortcomings Conclusion Gary Hendricks runs a hobby site on digital photography.
