Product Description

The L-series is Canon’s flagship professional lens range, designed to include outstanding image performance, ultimate operability and weather resistance. The EF 24-105mm f/4L IS USM offers a lightweight alternative to the renowned EF 24-70mm f/2.8L USM. offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 105mm without having to vary the shutter speed.

Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. The 3 stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions.

The ring-type USM motor found in the EF 24-105mm f/4L IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improv AF algorithm contribute to speed performance. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. Photographers can choose manual focus instantly and at any time simply by moving the manual focus ring without first having to switch out of auto focus mode. Circular aperture producing attractive background defocus Inner focusing, ring USM and new AF algorithms for fast and quiet autofocusing Manual focusing enabled even during AF mode (full-time mechanical manual focus) Only environmentally friendly lead-free glass used in lens construction Filter diameter 77 mm / Dimensions (dia x len)

I purchased this lens to serve as my primary lens and have been very satisfied with its performance as such. It has a great focal length range. I believe this is why it excels as a general lens. The IS helps greatly when zoomed in, however it does not help as much for low-light situations. In general, I have not had nearly much success in low-light situations with this lens at least for people. I have a f/1.4 fixed lens that works much better in low light. I find that this lens works decently well for low-light nature shots though.

Unfortunately I find my shots taken at f/4.0 to be rather soft. I understand that most lenses do not perform as well at the low end of their aperture. So I try to keep it above f/5.6 unless I really need more light. However, zoomed in at f/4.0 does create great background blur.

If you want only one lens this lens is great. I keep it on my camera almost all the time. Unfortunately my wife finds it a little too heavy for carrying for long.

This lens is one of the best general purpose, all-around lenses in Canon’s lineup. In order of preference, here are the top 5 things that I love about this lens:
- sharp images
- very versatile range of focal lengths
- image stabilization
- constant f/4.0 aperture
- L lens build quality

Because of the quality glass that Canon puts into its L lens series, this lens takes some tack-sharp photos. The range of focal lengths is excellent for portraits, stills, some landscapes and architectural shots. The auto-focus is fast on all focal lengths. The image stabilization is huge — it gives you up to 3 additional stops in aperture. This translates to action-stopping shutter speeds. The constant f/4.0 aperture means that you don’t have to suffer a decrease in shutter speed as you zoom in on a subject, a problem with variable aperture zoom lenses. Although the f/4.0 is not as desirable as an f/2.8 for low-light situations, it is great in decent lighting. I have a Speedlite 580EX II, so the range of that flash works perfectly with this lens when the situation calls for a hot shoe flash. Finally, the build quality is top-notch. The auto-focus is quiet, the lens body is rugged, and the weather-seal is very effective.

I was debating between this lens and the Canon EF 24-70mm f/2.8 L lens. Although I would have loved the 24-70mm’s constant f/2.8, I found the lack of IS and the loss of 35mm in focal length to be a huge compromise. With the 3-stop gain using the IS on the 24-105mm, I get back more than the 24-70mm’s f/2.8. For bokeh purposes, the 8-blade aperture of the 24-105mm is still very good, although there’s no question that a wider opening would provide even more blur. The only thing that would be able to pry this lens away from me as my favorite all-around lens is if Canon came out with a 24-105mm L IS lens with a constant f/2.8. But then that would be a huge lens, and might start getting in the way of effective everyday use. Right now, this lens is the perfect size for my general-purpose needs.

Overall, I am tremendously satisfied with this lens. I may eventually still get the 24-70mm f/2.8 L, but might wait to see if Canon introduces that with IS first.

This is a great lens. My first L lens and I am sold. Great clairity. Now my standard lens.

Awesome lens, delivered on time and in good condition. My only complaint is that the canon box is not sealed; so, anyone could handle it before it arrives.
I would like it even more if it was faster (2.8);but, it would surely be out of sight pricewise in that case.

This lens bought for general use including many meetings.
Am able to work entirely without flash, even in darkened rooms during PowerPoint presentations. Superb — allows extremely low shutter speeds.

Cocalo, started in the late 1990?s, quickly became one of the most exciting new baby bedding designers, mainly through its introduction of baby bedding collections under the Baby Martex, OshKosh, and Kimberly Grant brands. Recently, they have begun to expand their own house brand of crib bedding, Cocalo, with bright and colorful themed bedding collections. Turtle Bay crib bedding is one of these recently introduced collections. Retailing for $170-180 for a 4-piece crib set (including comforter, bumpers, dust ruffle, and sheet), this bedding appears to be an excellent value.

Turtle Bay bedding features vibrant hues of blue and green which were perfectly selected and combined to communicate an aquatic scene. The fabrics used are all very ?touchable,? including chenille, sherpa, and terry. The comforter also features an effective use of rickrack and incorporates some higher quality woven fabrics. In woven fabrics, differently dyed or colored threads are woven together in a manner to create the desired pattern. Contrast this with printed fabrics, where a pattern is imprinted on the surface of a solid colored fabric. Woven fabrics are superior to, and more expensive than, printed fabrics, being more vibrant, durable, and color-fast.

As if the colors themselves were not enough, Turtle Bay features extensive embroidered appliqu?s of turtles, fish, and starfish. Close examination of this embroidery shows that a great deal of effort was put into making these decorative features high quality. As compared to other brands I have seen, there is no ?bleeding? of appliqu?d fabrics outside the lines of the embroidery. See baby bedding. Baby Supermall?s crib bedding collections include all those made available by
