Canon 70 to 300 mm IS USM with f 4 to 5.6 is also codenamed as the 0345B002. IS stands for image stabilizer that operates on a 3 stop basis offering superb reduction in blur due to camera shake. It is also the worlds first interchangeable lens that uses image stabilization having superseded the 75 to 300mm IS USM from Canon. Designed specifically for long-range pictures without the use of a stand, it is perfect for sports lovers and nature admirers.
The new Canon interchangeable lens, 70-300mm IS f4-5.6 USM is quite capable of taking long shots at protracted speeds such that it offers one additional stop over the last model. This does not however increase the blur motion of the camera. It only allows picture takers to shoot something at 1 by 60 seconds even though the actual action is over in just 1 by 500 seconds. Thanks to this reduced blurring and additional stop, low light pictures come out much clearer.
In this canon lens, IS works using gyro sensors. These sensors simply notice the tiny movements happening inside the lens and take corrective measures using a perpendicular lens structure such that all light rays that leave their intended place on the sensor return back to them. There are two modes for IS in the Canon 70-300mm USM, one is for moving objects and the other is for immobile objects. Mode 1 will correct in both directions so that the immobile subject is captured perfectly while Mode 2 only corrects in either direction so as to capture a moving object. The IS system intelligently shuts down when it is used on a tripod without any need to manually tinker with it.
The upgraded Canon lens now comes with better auto focus capabilities. First, the USM micro controller is more adept at sudden AF changes using ultra sonic frequencies. Secondly, it operates at a very silent setting using a higher torque ration to provide better precision and accuracy thus ensuring improved focal measurements.
Being such a large lens, it is easy to damage or scratch the glass surfaces when it is stored. To prevent such a disaster, it comes with a zoom ring lock that locks the zoom of the lens in the wide-angle setting. You can carry the lens in its travel kit without the lens extending inside and hitting something.
The EF 70-300 IS f 4-5.6 USM operates an EMD device using circular aperture. The purpose of this component is to provide for better focus on the subject with less stress on the surroundings. The result is that a defocused background emerged with the subject isolated even at larger apertures.
Ghosting and flares are less prominent in this lens. It utilizes a special kind of spectra lens coating that by shaping lens elements detracts from the reflection on the sensors. What you get in return is a better image with crisper edges and balanced tone of colors.
A distance measurement chip inside the 0345B002 Canon lens directly communicates with an E-TTL II flash unit such that it can set up a perfect flash. Moreover, it is fully compatible with EOS 5D and EOS 1D models. This lens shall also hook up with the EX Speedlite series offering better flash and focus.
