A great general-purpose lens , Canon EF 24-70mm

 Canon EF 24-70mm

 
 I've owned the 24-70mm for almost a year now. This lens has been a favorite of many since it replaced its well-regarded predecessor, the 28-70mm. It shoots images that are very sharp and have excellent contrast and saturation. It's sharp wide open and only gets better when stopping down. The USM (Ultrasonic Motor) focuses very fast, and full-time manual focusing is allowed. I've thought about buying a 50mm f/1.4, but the results from this lens are so good, I'm having a hard time justifying the purchase. I've been nothing but pleased with the pictures I get from the 24-70mm. The constant f/2.8 aperture is great for shooting indoors and produces a very nice bokeh (background blur) when shooting portraits. This lens is much heavier than comparable consumer-grade zooms, but I don't object to the weight. I actually like the heft and feel of this lens on my 20D. The only feature I wish it had is IS (image stabilization).

The one thing preventing an unqualified recommendation is the recent release of the Canon 24-105mm f/4.0L IS. The latter lens costs about the same and has some noteworthy advantages. It is .7" shorter, .2mm narrower and .6 lbs. lighter. It has 3rd generation IS that gives you a 3-stop shutter speed advantage when shooting handheld. I know from my 70-200mm f/2.8L IS that image stabilization is a very welcome feature when shooting handheld at slow shutter speeds. And, obviously, the 24-105mm adds an extra 35mm of focal length on the long end.

The 24-70mm bests the 24-105mm in one way: It's a faster lens. That translates into the following advantages: At f/4.0, the 24-105mm cannot stop subject motion blur as well in low-light situations where the 24-70mm's f/2.8 can give you a shutter speed that is twice as fast. Note that IS does not have any impact at all on subject motion blur, only on camera shake on your end. If bokeh (background blur) is important to you, the 24-70mm will have a slight advantage over the 24-105mm given its wider aperture. A wider aperture also helps a camera focus a little better in low light.

The first run of the 24-105mm had a flare problem (see Canon's Web site for more info), and the early production models have been recalled. But the problem has now been fixed. You'll have to consider your photography priorities when deciding which of these two excellent lenses best suits your needs. You would be well served by either.

Update 5-17-10: It's been 4 1/2 years since I wrote this review, and I continue to use and enjoy my 24-70mm, which is now paired with a Canon 7D. Anyone considering buying this lens today, however, should know that a major Canon rumors Web site is reporting Canon is getting ready to update this lens in 2010. There are reports that the mark II is currently being field tested, and the new version is rumored to have image stabilization. No doubt, a mark II with IS would cost significantly more than the current version. FWIW, Canon updated their 70-200mm f/2.8 IS earlier this year; the mark II version of that lens brought improved optics and the latest generation of IS, but it was priced $500 (MSRP) more than its predecessor. A mark II version of the 24-70mm would be adding IS to a lens that doesn't currently have that feature, so the increase in price could be even more than $500. Just something to consider as you plan your purchases.

Wonderful Prime Canon EF 35mm Lens for the Price

Canon EF 35mm f/2 Wide Angle Lens for Canon SLR Cameras


Canon EF 35mm f/2 Wide Angle Lens for Canon SLR Cameras 
Canon EF

Bought this lens as a 'standard' prime lens for my Digital Rebel XT. What I found was that it was a fast, sharp, and lightweight lens that made the camera great for long walks. This would be the perfect lens to take to an amusement park, hiking, or biking where size and weight are a concern.

I've also used this lens for macro photography and portraits where it shines. The F2 Bokeh is wonderful and center sharpness is superb even at F2, much better at F4 which is what I use most of the time.

On the negative side, autofocus is noisy. To compare, it's like a drug-crazed wasp trapped in a matchbox. Maybe a mosquito buzzing close to your ear. It's not louder than the shutter, though. If this were a film camera and I was trying to take candid shots, I'd complain more, but it's a 56mm equivelant lens.

Another negative is build quality. They really should make the body of this lens out of thicker plastic. No reason to skimp there as the 'feel' of the lens certainly gives you much more confidence for very little weight penalty. Make it feel solid.

I've got a 52-55mm step-up ring on it as I've got a slew of 55mm filters. This also helps in that the lens cap is further from the body of the lens and easier to remove and replace.

If Canon had made a faster lens in 28mm at the same price point, I would have gone that way. For my tastes, it would have been preferable to have that extra field of view assuming the quality was as good.

All I bought at the price $299.00  dollars from website amazon.

 I'd just got into SLR photography and the first few months with the 35-90 lens that came with the Canon Rebel 2000 were outstanding. I never realised there was SO much difference between a point-and-shoot and an SLR. After reading p on some of the books about photography, I reaslied an important point was getting the right framing and getting close to the subject. So I set out to look for a cost effective zoom lens that would give me that flexibility. I tried the cheeper rip off lens in the loal camera store and found their mechanisms stiff and slow focussing. I stuck my neck out for a canon make lens, and this one jumped out at me. It's perfect, the shot are crystal clear, the zoom is smooth and the autofocus is just as good as with the smaller lens. How do they make these lenses so cheap when competing lenses are more that twice the price? highly recommended for a novice like myself whodoesn't want to sped too much for telephoto zoom capability. I'm now looking for a canon 2x teleconverter to add to my range.

All I bought at the price $128.23 dollars from website amazon.

Zoom Lens for Canon SLR Cameras

I have to say, "Wow I love this lens."

I'd recommend this lens for three kinds of people:

1) People who want to get a taste of the L-series lenses who need a lens in the 70-200mm focal length relatively inexpensively;

2) People who already own the 70-200mm f/2.8L IS lens who have to lug that huge thing around for a long time;

3) People who want a L-series 70-200mm lens who don't NEED f/2.8 or IS.

Call me a wimp, but shooting 1000-2000 shots a day in the field with the 70-200mm f/2.8 IS gets tiring, especially if you're hand-holding. This lens is relatively inexpensive for being L-series glass, the difference in optical quality is almost imperceptible from the f/2.8, and it's sturdy and ergonomic enough to use all day long.

When I plan on shooting the whole day, especially over the course of several days, this is the lens I take with me, NOT the f/2.8 IS. It's shorter, narrower, and lighter. While you may not feel the difference when shooting for a couple of hours, take two people of equal endurance and strength and give them the f/4 and f/2.8 IS and send them out for a day and you know who is going to come back with the sore arms when the day is over.

On a 1.6x FOVCF body, the 70-200mm focal range makes this lens a little tight; but at 1.3x or 1.0x FOVCF, this focal length range is quite awesome. When I travel, I like to pair this lens with the 17-40mm f/4 and use my feet to fill the gap between 40 and 70mm (I also take along el-cheapo 50mm f/1.8 so I can shoot in low light, and the 1.4x teleconverter to give myself an effective 450mm reach) -- all of this is a good, lightweight, relatively inexpensive package. Also, while being quite a chunk of pocket change, this lens is nowhere near as expensive as the f/2.8 versions, and so it's a lot less of something to worry about when traveling or shooting under adverse conditions.

As so far, I have found NOTHING that I do not like about this lens (well, except for the one-stop loss from f/2.8).

I have to say that if you are looking for a single lens to do General Purpose work, this is not it. This lens is for specfic purposes. This lens works best as one-half of a pair, taking the upper useful focal lengths, while you use something like the 17-40mm f/4L or the 24-70mm f/2.8L to handle lower range of focal lengths. If you're looking for a carry-everywhere never-change lens, try the 28-135mm f/3.5-5.6 IS lens. It's a great value, the focal length range is in the sweet spot, and the optics are not bad.

Otherwise, if you fit into one of the three categories at the beginning of this post, I would highly recommend this lens to you.

Canon PowerShot SD780IS

I just purchased this Canon on a whim, earlier today at Best Buy. I have been tinkering with it for the majority of the evening. My previous SD300 is still working like a champ, however I have been considering a video camera for some time...after some peering at the video camera counter I wandered over to the point and shoot table... what initially drew me in to the SD780IS was its appearance on the display stand. The sleek matte-black body is very eye-pleasing...then I looked at the specs. and realized that it shoots video in HD! (1280x720) Then all the other attributes made me realize that it was time to update my "everywhere, anytime" camera.
I proceeded to check out some of the other Canon SD cameras. The SD960 became the other candidate...it has a little more glass(4x)zoom, over the SD780's (3x)zoom. The SD960 has an appealing f2.8 apeture over the SD780's f3.2. The SD960's screen is more tailored for the HD video capture as it has a 16:9 ratio LCD panel. (Kinda nice for instant viewing ON THE CAMERA)
After some thought I went with the SD780 for these reasons:

1. The HD video capability is awesome and comparible with the SD960. It has a HDMI jack. The traditional 4:3 screen does not bother me, because the video is ultimately going to be viewed on a HD TV.(There will be an upper and lower bar on 16:9 playback through the SD780's LCD).

2.The weaker 3x zoom is not a big deal as this camera is for general shooting(out w/ freinds, bars, random afternoon at the beach, mountain biking, etc.)and with this camera EASLIY fitting in my jeans pocket or camelbak, the portability is what gives me the opportunity to document those moments, that would otherwise be missed. The SD960 is a little bulkier(but still small). I do also shoot with a Canon 40D, accompanied with L optics, but the weight and bulkiness do not lend to certain shooting circumstances. (as mentined above)

3. The user interface on the SD780IS is like most (if not all?) preceeding SD cameras. While there is not much control in the way of shooting settings, feature buttons like flash override, AE lock, AF lock, and exposure compensation are present on the camera body. The SD960IS has two buttons and a jog wheel, which lend to swims in the menu. I'm sure the new interface on the 960 is intuitive, but I liked the 780 due to its similarity to my old SD300.

I am very happy with the results produced thus far with the SD780IS. The HD video is excellant, however it should be known that once recording you can only zoom digitally. Low light cabilities and sound in video mode are excellent. The stills I have taken look great. Also, to the budget-minded who are upgrading from older digital point-and-shoots, a class 4 minimum 4GB or 8GB SDHC card would be well suited due to the demanding memory of the 12.1 million pixels, and HD video. Also, most old card readers will not process the the SDHC cards so you may have to purchase a new card reader as well.

I have to mention it again...the small size of the Canon SD780IS is mind-blowing...and the functionality actually mirrors its beauty.

Debating Between a Canon 50D and a Nikon D90? Read This!

Canon EOS 50D 15.1MP Digital SLR Camera with EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens




 Canon EOS 50D 15.1MP Digital SLR CameraCanon EOS 50D 15.1MP Digital SLR Camera

Canon 50D

Before you read this review, please note that the Canon 50D and D90 are not in the same class and are targeted at different markets, but there are still many people, including myself, comparing them with each other due to the relatively small difference in price. The Canon 50D should be compared to the Nikon D300, but since the D300 is clearly a better camera, there is no point. The 50D is in fact, somewhere in between the D90 and D300. With that being said, I hope you find my review helpful.

I spent a lot of time researching and comparing the Canon 50D with the Nikon D90. I picked the 50D. I hope my information here can help some of you out there making the same comparisons.

First of all, I highly suggest that you go to a local store and actually hold both cameras, play with them and get a feel for them. You will notice right away that the D90 feels cheap and is just made of plastic. The 50D, on the other hand, is made of magnesium-alloy and feels sturdy. It actually feels like a high-end camera. The 50D is also weather-sealed, unlike the D90. Build quality is extremely important, so keep that in mind. I also found the menus and button locations to be more user-friendly than the Nikon's.

I read a countless reviews on the 50D and D90. Most D90 reviews were pretty consistent with each other. The D90 is a great camera that provides excellent image quality, can take 720p videos and is $300 less than the 50D. The 50D review were also pretty consistent with each other. The 50D is not much of an improvement over the 40D, the increase to 15.1MP resulted in a small increase in image quality and resulted in more noise at higher ISO settings, it cannot take videos and is $300 more than the D90.

From a value standpoint, the D90 is a better camera. It's a few hundred bucks cheaper than the 50D and can take videos. That's pretty much where the comparisons end. Here's why.

1. The D90 isn't even a direct competitor of the 50D. The D90 is aimed toward the consumer market while the 50D is aimed toward the prosumer market. However, I still couldn't resist comparing the two, since the D300 was out of my budget.

2. Video Mode - Nikon released the D90 with a sub par video recording feature. It maxes out at 720p and does not, I repeat, DOES NOT have auto-focus. From my experience with the D90's video mode, the combination of holding the camera with one hand while focusing with the other and walking around resulted in, well, bad videos. If you want to take videos, get the Canon T1i.

3. Performance - The 50D, as with other prosumer level cameras, uses CF cards while the the D90, as with other consumer level cameras, uses SD cards. CF cards offer higher capacities, but more importantly, faster speeds. The 50D is capable of taking 6.3 frames per second in continuous shot mode while the D90 is capable of taking 4.5 frames per second. That's with JPEGs. Try continuous shooting with the D90 in RAW mode, and it will just beg you to stop. The D90 just isn't made for high speed photography. It's made for taking pictures when you are out on vacation with the family. The 50D, on the other hand, was designed for high speed photography, such as sports and and capturing moving objects.

4. Image Quality - Both cameras offer excellent image quality. It has been said in several reviews that the 50D produces noise at higher ISO settings than the D90 and even the Canon 40D. The reason for this is the higher MP count combined with the small size of the APS-C sensor along with the low quality of the lenses that were used in the reviews. If you plan on buying the 50D, PLEASE invest in a good lens to take advantage of the camera's increased pixel count. Had better lenses been used in reviews, the 50D would have received even better reviews. The 50D is not a consumer/enthusiast level camera, so why use cheap lenses to review it?

5. Live View - Wow, Live View is a sweet feature in DSLR camera. If you have an important shot to take, Live View can help you immensely! The 50D and D90 both have Live View. The D90 only has one auto-focus mode in Live View, which is Contrast Detect. The 50D has Phase Detect and Contrast Detect. The D90 can only zoom in 6.7x, while the 50D can zoom in 10x. Why is this important? The more you can zoom in, the more precisely you can dial in the focus. In addition, the 50D also offers micro focus adjustment to really dial in the focus. The D90's Live View is adequate for the average casual user, but it's completely unacceptable to a higher end user. The 50D's Live View feature caters to a more demanding photographer.

6. Value - The D90 is a few hundred dollars cheaper than the 50D. It has features that attract the average consumer, such a video. It produces great images worthy of a prosumer level camera, but lacks the feature and flexibility that a prosumer level camera offers, such as better build quality, better ergonomics, faster continuous shooting, full featured Live View and better tweakability. If these features are not important to you, get the D90. However, as you improve your photography skills and start to photograph a wider variety of scenarios, you will find yourself wanting the additional features that the 50D offers.

The question you should be asking yourself is - What do I want to do with the camera? Do you need a camera like the 50D, or do you see yourself needing its additional features down the road? The 50D might be too much camera for many people. For that reason, I highly recommend the casual user to get the D90. For you real photographers out there, get the Canon 50D. You will not miss the video feature, trust me. If you really want a Nikon, get the D300 (which does not have video either).

Sharp, fast, inexpensive, Canon EF 50mm f/1.8 II Camera Lens

Canon EF 50mm f/1.8 II Camera Lens


Canon EF 50mm f/1.8 II Camera LensCanon EF 50mm f/1.8 II Camera LensCanon EF 50mm f/1.8 II Camera Lens


Once upon a time the 50 mm lens was THE standard camera lens and was THE optical benchmark by which manufacturers were judged and compared. Although the basic lens focus has now shifted (at least at the low to mid amateur level) to zooms - you can still benefit from years of research and development that went into designing the 50 mm lens and this here lens may be the best lens, dollar for dollar, that you can ever buy. The question is can you afford not to own this lens?

Years of development have brought us a lens that has a fast aperture of 1.8 - far faster than any consumer zoom lens - and that is sharp as a filed tack. Be forewarned about the sharpness . . . if you are taking pictures of people, this lens is unyielding in its sharpness and may well surprise you and your subjects whose every blemish is captured. The lens has a fabulously shallow depth of field if you want to use the 1.8 aperture to blow out a background. This lens is also ridiculously inexpensive. It is not USM - so it is a little loud. It does not have a moving focus scale. For the money though - this is heaven.

As to the build quality - yes, it is plastic. No, it's not built like the Rock of Gibraltar. If you are going to give this lens extensive use as your everyday lens and you shoot a lot, it may not hold up all that well as one reviewer suggests. However, I've now had this lens and used it fairly regularly (although not as the primary lens) for about 8 years and it is still in great condition. In my mind, spend the $$ on this first before you go and drop $330 on the 50mm 1.4 USM lens and I think you'll find it gets the job done nicely and that the extra $250 on the 1.4 may not be worth the difference in build (major difference), speed (minor difference) and image quality (minor difference).
