Canon EF S 18 55mm f 3 5 5 6 IS SLR Lens




Equipped with Canon’s Optical Image Stabilizer (IS) technology, the Canon EF-S 18-55mm standard zoom lens is ideal for just about any application. IS technology compensates for camera shake by providing the equivalent effect of a shutter speed up to four stops faster. This allows you to take sharp handheld shots even in low-light conditions–a must for sports and nature photography. The lens also offers an aspherical lens element that corrects for aberration, thus producing a topnotch image throughout the zoom range, and a circular aperture that exquisitely renders out-of-focus backgrounds. Despite its minimal size, weight, and cost, the lens expands the picture-taking possibilities any time slow shutter speeds are needed.

User Ratings and Reviews

3 Stars An OK lens, not a great lens
The AF is slow compared to Canon USM lens, is slow even compared with Pentax screw-driven lens.

The image quality is improved significantly over previous non-IS versions. The image quality is good for its price. But don’t expect too much, it is nowhere near other higher grade lens from Canon. Even Canon 50/1.8 and 50/2.5 Macro lens beat the 18-55/IS easily.

5 Stars Good value for money
This lens is a vast improvement over the kit lens that came with the Rebel XTi. Good low light photos and less noise. I would definitely recommend this lens for anyone suffering with the kit lens.

5 Stars Great basic lens
This is the lens that normally comes in the kit. If you need a new Rebel, get the kit! We ended up paying more for it separately. What happened was my old camera quit working. We thought it was the body, so we just purchased a new body. Nope. The lens was broken! So then we had to purchase a lens separately. This is a nice basic/starter lens and works great for general photos. I do a lot of animal photos, and it’s worked fine. The next lens up cost more than the camera! So if you just need a basic lens, this does work, takes nice photos, and won’t break the bank.

5 Stars Great, yet cheap little zoom lens
While Canon produces many fantastic lenses, they do offer a lower-quality line at a much cheaper price. Mind you, Canon does this to broaded their market-share and to potentially create loyal customers from this group.

I have been looking for a simple small lens to attach to my camera when I am not doing work for money. I read about the size and weight of this lens and was pleased by the many good ratings, so I decided to get it. I was not disappointed. After a month now, the lens performs as it was stated, smooth zooming, the USM is heard, but it’s nothing bad, and the IS works flawlessly.

I have had no problems whatsoever mounting or dismounting the lens from my EOS 30D body, which stores beautifully amongst my other gear due to its small size. My professional lenses are twice the size and not having to carry the extra weight is a godsend.

I do wish the lens was made from more robust plastics, but if they did, the lens’ price would be higher. I will merely try to baby the lens every step of the way so it will last the longest possible. All in all, this lens is worth the money you spend on it, which is why I rated 5 stars.

4 Stars Nice Suprise
I bought this lens just to have it as a back up to my trusty Sigma 17-70 lens. It has not left my 40D since.I picked up the 18-55 IS as a “USA White Box” lens(was removed from a kit by a retailer).It is light,easy to handle and very sharp.The auto focus is fast and accurate.My thinking was that this might be an temporary lens until the New Canon 15-85 came out. I don’t know that the new lens would justify the extra $650.00. The 18-55 IS does have its short comings,but I feel the image quality and price outweigh them. I team this lens up with the 55-250 IS (another amazing value lens)and a fast prime like the 28 f/1.8 and I am covered for a day of walk around photography.

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




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 improved 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)

5 Stars Great Lens
I am an amateur and this is my first L lens. If you could get only one lens, THIS is the one!

The pictures and videos look great.

4 Stars Great Everyday Lens
I had tried this lens first on the 5DMII and thought the IQ was terrific. I then tired it on the 40D and although not as great as on the 5DMII the difference from my non “L” lenses was appreciable. When I purchased my 7D I was hoping this was the kit lens so that I could take advantage of the discounted price, but unfortunately it wasn’t part of the package. I payed full price for it and that is my only complaint. The IQ doesn’t seem to be as good on the 7D (a cropped sensor) as is on the full frame 5DMII, but is still much better than the 17-55 mm that I used as my everyday lens for the 40D. For the price, I think it could have been better than an f/4.0 -especially for indoor low light situations. It’s quiet and focuses quickly. Overall, I think it’s a great lens and if you can swallow the price then you won’t regret getting it.

4 Stars Quality lens
Very good quality lens, feels solid and the picture quality is lovely.

Lens ships with UV filter, canon soft case and sun shield.

5 Stars Canon EF 24-70mm vs. 24-105mm IS: Read this if you are a hobbyist
I am a hobbyist and this review is for people like me. What I mean by that is that I take pictures for fun and nobody buys my pictures. I mostly shoot landscape, nature, and portraits of family, friends, and relatives. I will refer to 24-70mm as the 70, and the 24-105mm IS as the 105. I first made the mistake of buying the 70, then I returned it with a hefty restocking fee and bought the 105 – I don’t have the slightest regret and I could not be happier. I’m taking my time to write this review so that you can spend your hard earned money wisely. Let’s analyze the trade-off between the two:

* Both lenses have excellent build and image quality. So these are not differentiating factors.

* The one and only advantage of the 70 is the one smaller f-stop. For me, this means more blur when I shoot portraits, so this is all good.

* The advantage of 105 over the 70 are as follows:

- You get an extra 35mm, which is 50% more zoom. I like this.

- You get a 3-stop IS. For me, this is a great advantage, because I rarely use tripods and IS saves the day. I would choose the 105 over 70 for the IS alone.

- The 105 is 10 ounces lighter and close to half an inch shorter.

The last part is the most important part: that additional 10 ounces make a heavy lens TOO HEAVY, and that extra length makes a big lens TOO BIG. Carrying the 70 on my 50D was a pain. I can assure you, the 70 is just too heavy to walk around and take pictures for fun. The keyword here is “fun”. The 70 is a pain, the 105 is fun. The 105 is still heavy, but not too heavy. It’s still big, but not too big. After having the 70 for a few weeks, I lost all my joy for shooting. It just made me very uncomfortable (and I’m 6-foot 2). When I replaced it with the 105, it did make a difference. I enjoy taking pictures now, once again. Pros might like the 70 because they need it for their professional work. But if you’re shooting just for fun, stay away from the 70 and get the 105.

4 Stars Excellent All-Purpose Glass
When purchasing the Canon EOS 5D Mark II, I had the option of purchasing it with this lens as part of the package. The combined price represented a savings and the focal-length range of this lens offers a practical, wide selection of options.

The f/4.0 opening at first does not seem very “fast” but all my prime lenses are not much faster, and none of my vintage primes offer auto-focus and image stabilization. This combined with the extreme ISO range of the 5D Mark II renders the f/4.0 of little concern. I have not yet been in a situation where I could not make an image with this lens – even in near-darkness!

It’s a huge heavy lens, which means it’s not going to be as convenient as that little cigarette-pack-sized point-and-shoot 10x zoom, but if you place convenience over all, you probably aren’t in the market for this type of gear anyway. This is convenient in a different way – photographic flexibility, spanning ultra-wide to short telephoto.

As with all zoom lenses, there are compromises to be made. Not fast, not small, it’s also probably not as sharp as a fixed focal length lens. But add up the cost of a 24mm, 28mm, 35mm, 50mm, 85mm, and 105mm, and see if perhaps the value of having them all in one lenses doesn’t tip the scale in favor of a lens perhaps not perfectly sharp, in favor of something you will likely be able to render many images without fumbling and breaking the bank.

And that’s not to say this lens is soft by any means. Sometimes I think all the hype about sharpness, beyond practical limits, is just one-upmanship. It’s the image that matters, and not everything is always sharp is it? I have uploaded some images to show the flexibility of this lens on the 5D Mark II, as employed by my eyes.

I find nothing yet to complain about!

Canon EF S 10 22mm f 3 5 4 5 USM SLR Lens for EOS Digital SLRs

Canon EF S 10 22mm f 3 5 4 5 USM SLR Lens for EOS Digital SLRs




With its effective focal length range of approximately 16-35mm in 35mm format, the EF-S 10-22mm f/3. 5-4. 5 USM is a remarkable lens with outstanding image quality that will take your photography into new dimensions and areas of dramatic expression. The super-wide zoom not only gives you the freedom to get exactly what you want in the shot, it dramatically alters perspective to allow for dynamic expression. The lens allows you to get extremely close to subjects, exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence, or for a pan-focus effect with everything from foreground to background sharply in focus. Exceptionally light and compact for its focal length range, the EF-S 10-22mm f/3. 5-4. 5 USM also has an incredibly close minimum focusing distance of just 24cm. A ring-type USM works in concert with the camera to provide super-fast, precision auto focusing and predictive tracking – with full manual override available at any time. Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare. A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.

4 Stars Good Lens, but not up to Takina’s 12-24 F/4
I bought this lens a week ago and have found it to be a good choice, though not up to Takina’s 12-24 F/4 which I would say is the best lens in this class. The Canon is lighter which makes it comfortable to shoot with a heaver camera like the 50D espically with a battery grip on, which I don’t own yet but plan on buying soon. The extra two degrees at the wide end is a big advantage also with this lens, though you lose it at the zoomed range this is not such an issue as I think most people who will buy this lens will have that covered buy another lens if the really need it.

This lens is soft in the corners especially wide open, this is common in a lens of this class and the Takina also does this but not to the degree of this Canon it also handles CA better and the Takina I would say has a much stronger build. Takina is well known for making tank lenses. I would take this lens over the Sigma and Tamron versions (Tamron usually I find to be the best for 3rd party lenses), but in my opinion, the Takina just out performs these lenses and does so with a constant F/4 aperture which is very important to me. Flare control does seem a bit better also with this lens though not by much, it can make a big difference in some shooting scenes.

This is a great lens overall, so don’t think I am unhappy with it. If the lens was cheaper I would probably recommend it but it’s the same price a Takina’s, Sigmas and Tamrons without the benefits so I will be returning it.

If you can’t get the Takina this would be a great second choice.

5 Stars awesome lens!!
I got this lens when I first got into photo and I had no idea what I was doing. I’m sure glad I blindly bought this lens! It’s such a fun lens to shoot with, super wide, nice crisp images. extremely durable too, mine has been hit by a couple skateboards and there has been no damage.

5 Stars Very Sharp Lens!
I took this lens out on a photo shoot with my Canon EOS Rebel T1i the day after I received it from Amazon.com. I had been a bit skeptical about purchasing it because I did not know how much I would need or like a truly wide angle lens, since I tend to prefer telephoto lenses. However, when I first used this lens, I was very impressed with the image quality and with what I saw through the viewfinder. The wide angle of view offers some very interesting new photo opportunities!

The images this lens produced for me were superb in terms of color saturation, clarity, and sharpness. The pictures were so sharp that I could crop them, keep only about 5% of the original image, and still have tack sharp pictures! Aside from the cheaper build of this lens, it performs on the same level as my “L” lenses.

As an added bonus, this lens offers an excellent depth of field with a close focusing distance of about 9 to 10 inches! That makes it possible to get close-up shots of flowers where every part of the flower is in focus – no more depth of field concerns!

When zoomed out toward the widest angle, my camera’s built-in flash causes a shadow from the lens to appear in the picture. But when an external flash is used, this is not a problem. I used a slim Circular Polarizer filter with this lens with no problems – no vignetting!

Before buying this lens, please understand that it is an EF-S lens that can be used only with Canon cropped sensors, such as the T1i, 50d, etc. It will not work with the full-framed Canon cameras (eg, 5d, 1ds, etc.).

5 Stars 10mm is just OMG!!
Everything you see through 10mm lens wide view is totally OMG-!! It is pretty expensive for beginner like me, but it was definitely a good buy. Build quality is very nice. USM is quiet and fast. Before you buy it, make sure you know it is 77mm, and not 58mm, so you need new UV Haze filter for it. I got a lens hood and it is huge!! Thats another OMG for me, but I will tell you, this lens is awesome. (or I should say, 10mm wide-view is awesome. I am a beginner and I don’t know much about sharpness and colors)

5 Stars Can’t beat the pictures this lens takes
bottom line, this lens takes amazing pictures you just can’t get with any other lens for this camera. Worth every penny.
