Like many folks my call on a telephoto zoom lens reduced to purchasing the Canon 70-200mm f/4L or the Canon 70-300mm f/4-5.6 IS USM. The trade offs appeared clear initially. the previous performs slightly higher (see Canon web site for MTF data), is best designed & designed, is quicker and has the "L" lens standing. User comments and ratings (at quite one site) are slightly a lot of favorable for the L lens. The 70-300mm has an improved IS and after all a extended focal length. each price regarding a similar thus cash wasn't an element in my call.
I eventually selected the L lens and was initially disappointed. Photos ranged from wonderful to not excellent in the least. In fact, I virtually came the lens. Eventually I found out the matter. My yard is heavily shaded thus most of the initial photo's were taken in low lightweight and that i had selected shutter speeds that were too slow. To avoid camera shake you would like to shoot at the reciprocal of the focal length or faster. Sounds easy however with the Digital Rebel XT (which i used to be using) you would like to contemplate the camera's one.6 multiplication issue. thus at 200mm you would like a shutter speed of 1/320 or faster not 1/200 like I initially thought. Once I created the speed adjustment things modified for the higher.
Still I even have some mixed feelings regarding my call. When the sunshine is nice this is often an amazing lens however with the IS feature offered on the 70-300mm i might in all probability get photos that i'll miss with this lens.
I can't fault the performance of this lens for its limitations and that i have given it five stars. In alternative words it will what it's presupposed to do o.k. however my message to alternative consumers is to contemplate where you're possibly to use the lens before shopping for. bear in mind IS becomes increasingly necessary as you extend the focal length. If your camera is already extending it by an element of one.6 you'll realize could be a terribly engaging feature.
