Canon EF-S 55-250mm STM Lens: http://amzn.to/XQxNim
The EF-S 55–250mm STM lens by Canon is supposed to offer better autofocusing while recording video, so I decided to test it out while also seeing just how good its stabilization was while fully zoomed in. For this test I used my Canon T4i as that was the first camera to take advantage of the STM lens' focusing capabilities. The newer models, the T5i and 70D, should both offer faster and more accurate autofocusing. None of the clips are altered in any way, I simply edited them together over a music track. If you have any questions, comments, or whatever else, feel free to leave it in the comments below. THANKS FOR WATCHING!

CANON EF-S 55-250MM LENS FEATURES
For photographers and videographers looking to add versatility and range to their lens collection, the new EF-S 55–250mm f/4–5.6 IS STM telephoto zoom lens is a dream come true. Compact and lightweight with Optical Image Stabilizer for up to 3.5* equivalent stops of shake correction, it extends the camera's reach significantly, capturing sharp images of far away objects, even when handheld. It features Canon's amazing STM stepping motor and a newly designed high-speed CPU, rear focus mechanism and improved AF algorithm for high-speed performance, supporting Canon's Movie Servo AF for smooth, quiet and continuous focus adjustments. The EF-S 55–250mm f/4–5.6 IS STM lens features one UD lens element that reduces chromatic aberration, helping to achieve excellent image quality with high resolution and contrast. The front element does not rotate, ensuring easy compatibility with accessories like polarizing filters, and full-time manual focus is available even while in AF mode. Enhanced coatings on the lens elements deliver excellent color balance and minimize ghosting and flare, and a 7-blade circular aperture delivers beautiful, soft backgrounds. The EF-S 55–250mm f/4–5.6 IS STM lens has a compact design thanks to a new six-group zoom system that provides a maximum magnification of 0.29x at the telephoto end and a minimum focusing distance of 2.79 ft./0.85m throughout the zoom range.
