Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras
Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras Reviews
This is one of the most popular lenses, and with good reason -- you get a lot of bang for your buck. It has an ultrasonic motor drive (USM) for fast focusing, image stabilization (IS), and a very versatile focal range that covers wide angle to mid-telephoto on a Canon 5D and a respectable 38mm to 168mm (1.6*24 ~= 38, 1.6*105 = 168) focal lengths on cameras with crop sensors, like the Canon 7D, the Canon Rebel series, and cameras with APC-C sensors (1.6x crop factor). Its only downside is its f/4 aperture limitation. On the upside, it has a constant f/4 aperture (i.e. the f/4 aperture setting can be maintained across all focal lengths). - Sharpness This lens is sharp across all focal lengths. I haven't noticed any degradation in image sharpness on either the 24mm or the 105mm end. However, the lens is sharpest between f/8 to f/11. Outside of this "sweet-spot" (i.e. below f/8 or above f/11) shots of distant objects are *noticeably* blurrier. (See uploaded images on the product page for a comparison of images shot with different f-stops: f/5.6, f/11, and f/22. The descriptions for the images begin with "For the pixel peepers out there...") For relatively close subjects, however, the difference in image quality across f-stops is a lot less perceptible - that's good news if you're using this lens for portrait shots and plan on opening up the aperture for a bokeh effect. - Chromatic Aberration (CA) The lens assembly uses Ultra-low Dispersion (UD) glass (reserved for Canon's best lenses), so chromatic aberration is minimal, even in bright light (where it's barely noticeable or imperceptible). In more even lighting, this lens shows absolutely no signs of chromatic aberration. - Auto-Focus (AF) The auto-focus is real snappy. Thanks to its ultrasonic motor (USM), it brings objects into focus in a fraction of a second. In the AI Servo mode, the focusing mechanism is very responsive for bringing even very fast-moving subjects into focus. However, as with all lenses, the auto-focus inevitably has a bit of trouble in (i) lowlight conditions and (ii) with surfaces that lack texture or contrast. - Image Stabilization (IS) The image stabilization is amazing. In my book, image stabilization is a must for a lens to be truly called a "walk-around" lens. For the times you don't have your tripod with you, the IS on this lens will prove very invaluable for helping you steady your shots, especially at the 105mm end! (It helps to bear in mind, too, the rule of thumb: the shutter speed should be at least as fast as the reciprocal of the focal length.) - Internal Focus (IF) The Internal Focus is a big plus, especially for landscape photographers who use a circular polarizer (also known as a polarizing filter). With Internal Focus, the barrel on which the polarizer is affixed doesn't turn and throw filter out of adjustment, so it saves you from having to readjust the filter after the subject is brought into focus. - Build This lens simply oozes quality. There's a good heft to it but it's not too heavy. Both the zoom ring and focusing ring turn very fluidly. The zoom ring is tight enough to prevent zoom creep. - Alternatives You Might Be Considering Canon EF 24-70mm f/2.8L USM: The EF 24-70mm f/2.8 has a constant f/2.8 aperture, but alas, it has no image stabilization, which is a real shame. The lack of image stabilization is definitely a deal breaker for most people, including myself. Canon EF-S 17-55mm f/2.8 IS USM: The Canon EF-S 17-55mm f/2.8 is an equally popular lens. (Note: it has an EF-S, not EF mount, so it's not compatible with the 5D. It's compatible all other bodies, such as the 7D, the Rebel series, and other Canon DSLR's with crop sensors.) With the 1.6x crop factor taken into consideration, this lens has focal lengths of 27-88mm. In terms of image quality, the 17-55mm f/2.8 is on par with the 24-105mm . It, too, uses Ultra-Low Dispersion glass. The only downside is it's not weather sealed (which is not a concern for me). If you don't mind forgoing "reach," I would highly recommend the 17-55mm f/2.8, which is one of the best low-light lenses you can buy. I use it for landscape and portrait, and it's my walk-around lens of choice. --- The quality of this lens is top-notch and definitely worth the money. It offers a very useful 24-105mm focal range without compromising on sharpness. The only limitation is the f/4 aperture. If this is not a concern for you, this lens is definitely worth consideration.. this is my Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras reviews
