Camera review: Canon Rebel XTi DSLR

Released on August 24, 2006, the Rebel XTi is Canon’s newest entry-level prosumer DSLR. It’s an update on the popular Rebel XT, and it’s different from it as follows:

  • Slightly thinner body, heavier (2.56in vs. 2.63in and 510g vs. 485g)
  • Newer, re-designed sensor with higher resolution (10 megapixels vs. 8.2 megapixels)
  • Sensor cleaning technology (dust shaken off the sensor with ultrasonic waves)
  • Bigger display (2.5in vs. 1.8in)

I only listed the significant differences above. You’re welcome to compare the detailed specs if you’d like, right on Canon’s website. Go to the More Information section at the end of this post and use the links listed there to get the full specs.

In my reviews of other DSLRs, like the Canon 30D, the Olympus E-510, or the Olympus E-500, I criticized the Rebel XTi’s small grip, and I still think I’m right. It’s much too small to be held comfortably in a man’s hand, and that’s unfortunate, because the camera is great in every other aspect.

In spite of the camera’s small grip, I was pleasantly surprised by the quality of the photos it produced, and I wanted to share my findings with you. I avoided reviewing it until now on purpose — as I said, I was displeased with its body design — but after using it, I’m happy to say I would recommend it.

I made a video review of the XTi, which should help you get a better idea of the its dimensions. I discussed the camera at length in the video, and also did a side-by-side comparison between it and my Canon 5D. You can watch it below, or scroll past it to read the rest of my review. You can also watch it here, or download it if you like.

I should also mention I goofed in the video. I talked about the XTi having the DIGIC III processor, but it turns out it still has the DIGIC II processor. What I said about the differences between it and the 5D and 30D with respect to exposure value settings is still correct, so don’t disregard that. You may or may not be aware that when you do not adjust the EV settings on a 5D or 30D, and you shoot outside in bright light, the processor will overexpose the shot. The quick fix is to dial down the EV by 1/3rd, and that usually does the trick. But that’s not right. Shots shouldn’t be overexposed, and I’m glad to see the XTi doesn’t suffer from that bug. It exposes shots beautifully, and you’ll see what I mean when you look at my sample photographs below.

Even though the overall design of the camera is similar to that of the larger DSLRs that Canon makes, certain differences are there, and they are caused both by the price and size of the camera. For example, being used to the 5D, I missed the small at-a-glance display on top of the camera. On the 5D, it lets me know what my settings are without having to consult the LCD screen. I also missed the large settings dial next to the LCD that’s a staple on every other Canon prosumer and pro DSLR. I love that dial/wheel, and I miss it on every non-Canon camera I use.

The exposure value adjustment button, along with the drive settings button, are located next to the display instead of the top of the camera. There is no jog controller for the focus point selection, either. But you can’t have everything. The Rebel XTi is an entry-level DSLR, so you can’t have features that are normally found on the more expensive DSLRs. Plus, its body size makes it impossible to have the same button arrangement.

Canon Rebel XTi (back)

Despite my gripes, I liked the size of the body, and I liked the feel of the buttons. They had a soft, glossy surface that made it a joy to press them. The small body of the camera makes it possible to hold it very comfortably in the palm of your hand, and that’s a huge plus, because you can stabilize shots a lot better that way.

I really liked the quality of the photos from the XTi. I shot in RAW format, and I was very pleasantly surprised to see how well exposed the photos were, and how accurate the color reproduction was. I’ll show you some photos very shortly where I made no adjustments in post-processing other than adding meta-data, and I think you, too, will find it hard to believe that those were RAW shots straight from the camera.

I can tell you this: the RAW files made by the XTi have better exposure and color, right out of the camera, than the RAW files made by my 5D. It’s a shocker, yes, but it’s true. I suppose that’s to be expected. The 5D uses technology developed in 2005, while the XTi uses technology developed in 2006. But still, I had to see it with my own eyes to believe it, and being a 5D owner who’s shot tens of thousands of photos with the 5D, this was a hard pill to swallow. Having said this, would I give up my 5D for a Rebel XTi? I’m tempted, but no. 🙂

On to the photos. These are two that I took in early afternoon light, which was bright and unforgiving. I shot in RAW and developed the photos in Lightroom. I had to do very little exposure adjustment. Can you believe how well the XTi exposed the photos and reproduced the colors? Can you believe the dynamic range of the sensor? I didn’t expect this from the XTi.

Here’s another photo that shows off the dynamic range of the camera. I shot this with the wonderful 18-55mm kit lens. If you’re confused by my characterization of that lens, watch the XTi’s video review, and I think you’ll understand.

Here’s a macro shot I took with the same 18-55mm kit lens. I was pleasantly surprised with the low noise at 800 ISO.

I said it before, and I’ll say it again. I love the colors that I get out of this camera! Have a look at these two photos to see what I mean.

Spoon!

I thought I’d put in a dog photo for good measure. This happy pooch posed for me in downtown Alexandria this past summer. I used Keith McCammon‘s XTi for the shot.

Smile for the camera

What else can I say? If I’ve missed anything, let me know in the comments. The Canon Rebel XTi is a great prosumer DSLR. You won’t have to try very hard to get wonderful photos with it, and its affordable price will help make your decision a little easier.

Lens comparison: EF 24-70mm f/2.8L Zoom vs EF 24-105mm f/4L IS Zoom

Have you ever wondered how the EF 24-70mm f/2.8L and EF 24-105mm f/4L zoom lenses would do if compared side by side? Which one would come out as the winner in real-world use? Here’s my answer to that question.

First, some recommended reading:

Those two reviews of mine should give you a good idea of what each lens can do. Now let’s talk about how they do when they’re together. 🙂 Here’s a photo of the two lenses. As you can see right away, the 24-105mm is smaller in both height and girth — it’s shorter and a little narrower than the 24-70mm.

When we look at the rear lens elements, we can see some differences there as well. The 24-105mm lens is on the left. If you look carefully, you can see a baffle in place. The 24-70mm lens has no baffle.

It’s possible that the baffle is there in order to reduce possible flare effects, since the focal range is longer. It could also be there to baffle us — after all, it is a baffle. 🙂 It’s also possible that the optics aren’t as high quality as those in the 24-70mm lens — they’re both priced the same, but the 24-105mm has image stabilization and an extra 35mm of range. On the other hand, I’ve seen a very similar baffle on the EF 14mm f/2.8L prime lens, and no one can say that the 14mm lens is made with cheap glass. So the more likely explanation is that it’s there to reduce lens flare due to the increased focal range.

(By the way, the baffle can be seen even more clearly in this product advisory from Canon warning about unacceptable levels of lens flare in early builds (2005) of the 24-105mm lens.)

Here’s another look at the lenses side by side, this time with the lens controls visible. As you can see, the only thing that’s different on the 24-105mm lens is that it’s got the IS switch. The controls seemed a little thicker on the 24-70mm lens. As for their durability, I assume they’re both long-lasting since these are L series lenses.

Chances are you can already know that the 24-105mm lens is lighter than the 24-70mm lens. It’s no small difference, by the way. The 24-105mm lens is 670g, while the 24-70mm lens is 950g — that’s 280g of difference! While both lenses extend outward as you zoom, the 24-70mm lens is more top-heavy than the 24-105mm lens, and that makes a big difference in wrist fatigue — the 24-105mm lens is less punishing and can be held comfortably for longer periods of time.

The weight difference is remarkable to me because the 24-105mm lens has 18 elements, while the 24-70mm lens has 16 elements. Canon managed to keep the weight down even though they placed extra glass in there and added image stabilization.

There are some limitations to being lighter and smaller though. The 24-105mm lens’ closest focusing distance is 1.48ft or 0.45m, while the 24-70mm lens’ closest focusing distance is 1.25ft or 0.38m. It also looks like the general consensus is that images obtained with the 24-105mm lens are somewhat softer than those obtained with the 24-70mm lens.

Other than the difference in focal lengths, another obvious difference between them is the maximum aperture. The 24-70mm lens opens up to f/2.8, while the 24-105mm lens only opens up to f/4. That’s a full f-stop difference, or a 2x reduction in the amount of light that can enter the lens. This is where the baffle comes in again. Since the baffle itself limits the amount of light that can hit the sensor in order to reduce glare, it stands to reason that the aperture can’t open up any wider. Even if it did, we’d end up seeing the baffle contours in our photos.

What the 24-105mm lens has going for it is the built-in image stabilization, which, in my experience, more than compensates for the reduced maximum aperture. See the photo below. I took it completely handheld (I didn’t prop myself up against anything) at a shutter speed of 1/15th seconds.

I tried to get similar photos with the 24-70mm lens, and I couldn’t, not without leaning against something to stabilize the lens. The slowest shutter speed I could use was 1/30th seconds with that lens. As I concluded in my previous review of the 24-105mm lens, the image stabilization counts for a lot and makes the lens truly versatile and useful.

While I’m talking about versatility, let’s not forget that extra 35mm of focal range. At close distances (6-15 feet), you don’t notice how much it matters, but when you start focusing on things farther away (30-100 feet or more), you realize how valuable those extra millimeters really are!

Let’s not forget bokeh. Both lenses have gorgeous bokeh, but the 24-70mm produces a creamier bokeh. That’s because it opens up all the way to f/2.8, while the other only opens up to f/4. If you do a lot of close-range photography, in tighter spaces, and you really need that bokeh (portraits, etc.), the 24-70mm would probably be a better candidate. This next photo was taken with the 24-70mm lens.

If you’ve got a little wiggle room and can position your subjects further away from things (walls, trees, background), don’t discount the 24-105mm lens. Its bokeh is right up there with the best of them. Have a look below.

In the end, it really comes down to your own, precise needs. I’ve heard of some people who only carry two lenses in their bag: the 24-70mm and the 70-200mm (both of which I reviewed here). They’re both professional-grade, L series lenses. They’re heavy, but they deliver the goods, and they’re versatile.

For my needs, I’d go with the 24-105mm lens. It’s lighter, has extra range, and has built-in image stabilization. I really enjoyed using it, and I seemed to get better photos with it than with the 24-70mm zoom. While it may not be as sharp, I didn’t notice anything that would turn me away from using it. I thought it was a superb lens and couldn’t believe the quality of the optics when I looked at the photos I got with it.

At least one commenter here asked how these two lenses compare, and I hope that I’ve answered that question in as much detail as I could give. If you have any other questions, pose them in the comments on this post, and I’ll try to answer them.

Lens review: Canon EF 24-70mm f/2.8L USM Zoom Lens

The EF 24-70mm f/2.8L USM lens is the professional standard zoom from Canon, and so far the golden standard for sharpness, contrast and bokeh in a zoom lens. Photographers drool over it and swear by it. Its focal range on a full frame sensor makes it very appealing for event photography. It goes from a wide 24mm to an almost portrait-length 70mm to allow for close-ups. It’s also plenty fast for a zoom — f/2.8 — just about the fastest a zoom lens can get these days. (I’d like to see an f/2.0 standard zoom, but I don’t know when that’ll happen, and the cost will probably be fairly high.)

I’m going to talk exclusively about the 24-70mm lens in this review, but if you’re interested, I also wrote a comparison of this lens and the 24-105mm f/4L zoom. You may want to read that as well, in order to get a better idea of how this lens performs.

As you know if you’re a regular reader, I write about how products feel and the results they give me. My reviews aren’t spec-heavy. I give you my honest opinion about a product, and tell you what results I got with it.

With that in mind, the 24-70mm zoom is a good lens. It’s plenty sharp, has plenty of contrast, and the bokeh is great. I liked it. But it’s heavy — really heavy. When you hold it in your hand, it doesn’t feel that heavy, but when it goes on your camera, your wrist really takes a beating, and it feels as if the camera’s body is going to give. This lens is incredibly front-heavy. That means there’s no chance of holding the camera with one hand for long when you use it. On my 5D, it’s really hard to use the lens without a vertical grip, which gives me more finger room. Without the grip, you have to support the lens itself when you take the shots, and then you have to be careful that you don’t grip the focus ring and impede the auto focus from rotating when you press the shutter button. I use a keyboard and mouse all day long, so I realize I may not be the strongest guy around, but I lift weights once or twice a week. Still, I tell you, this lens really took its toll on my wrist joint and finger muscles. It was a real workout. I didn’t expect this kind of weight from a standard zoom. I did expect it from the EF 70-200mm f/2.8L IS USM zoom. If you’re so results-oriented that you’re willing to overlook the weight, great, get it, you’ll love the results.

I mentioned the useful focal range above. Let me illustrate it with a few examples below. At the wide end, you can capture beautiful landscapes… or nice wide angle shots of buildings. At medium range (30-60mm), you can get photos like these. The lens also has a very useful close-focusing range (0.38m), which allows you to get close-ups like you see below.

Let’s talk about low light. This lens has no image stabilization (like the 24-105mm zoom) and that means the maximum aperture of f/2.8 starts to show signs of strain in low light. It means we have to bump up the ISO and make sure the shutter speed stays at or above the focal length, stabilize the camera, and/or use a flash. Like I said in the opening paragraph, this isn’t a fault of the lens — f/2.8 is the fastest aperture for a zoom lens on the market, so that’s just how things are.

I enclosed a few photos taken in low light above. The first was taken inside a piano store, and although there was plenty of fluorescent lighting, I found that it wasn’t quite enough to shoot freely, like I would have done with a faster prime lens. I can’t argue with the sharpness and bokeh though. It’s beautiful.

There’s a second interior photo, where I had to use a speedlite. I used the 580EX II, also from Canon, and bounced it off the white ceiling. The lens does fine with a good speedlite, so that’s no problem.

The last two low light photos were taken in downtown Bethesda at night. For the first, I stabilized the camera with both hands on a balustrade in order to take it. The second photo of a VW Bug was taken handheld from a lower angle.

A lot of photographers use this lens for portraits, so I thought I’d show you a portrait I took with it as well. It’s on my wife’s website, Fun Piano Lessons. The tele end of the focal range is just right for portraits, and the sharpness, contrast and bokeh are great, especially with a wider aperture like the f/4 used in that photo.

All in all, this is a lens that does not disappoint. I expected professional results when I used it, and got them, without a doubt. The only two things that I minded were the weight — in particular its front-heavy distribution — and the lack of image stabilization. But if you were to get this lens and the EF 70-200 mm zoom, you’ll have covered most of the useful focal range you’ll need with just two very versatile lenses. Some food for thought there.

Lens preview: EF 14mm f/2.8L II USM Prime

Canon chose to announce the availability of a new wide-angle lens along with the EOS-1Ds Mark III. It’s the new EF 14mm f/2.8L II USM prime, which upgrades the existing EF 14mm f/2.8L USM.

The lens will feature the same correction for rectilinear distortion, but with improved dust and water resistance, a round aperture for nice bokeh, and a better-designed cap, that’s held to the lens by a stopper. Having briefly used the existing 14mm prime, I can tell you the lens cap kept falling off, and it was a real hassle to get the lens out of a gear bag if the cap end was facing toward you. It would come off immediately, and then you’d inevitably touch the lens surface with your fingers, which required a cleaning.

The price for this lens will be approximately $400 more than the street price of the existing 14mm prime, at around $2,199.

Camera review: Canon EOS 5D DSLR

With the release of the new EOS 40D and EOS-1Ds Mark III, it’s easy to forget the camera that changed the entire market: the EOS 5D. It was the first affordable full-frame sensor DSLR ever. I bought it in April of this year, and I still don’t regret the purchase. As a matter of fact, I love my 5D!

Updated 2/1/09: I’ve also written about the new 5D Mark II.

Canon EOS 5D (front)

Yes, the newer models that came out have more resolution and low light sensitivity, in addition to the EOS Integrated Cleaning System, which shakes dust off the sensor. It’s annoying to have to clean my 5D’s sensor with swabs once in a while, and to get out my bulb air blower and make sure there’s nothing inside the sensor chamber, but I don’t mind it that much — except when I have to use the Heal brush to get that dust off my photos. Even then, Adobe Lightroom makes it a breeze with its wonderful Heal/Clone tool.

I went back through Canon’s PR section and dug up the 5D’s original press release. You know how we have a healthy amount of mistrust when we read press releases? Well, read through that one and tell me if anything written there turned out to be untrue.

All these new models make me wonder what Canon will do with the 5D. I don’t think the 5D will go away. It fulfills a very important role in the marketplace and it’s beloved by many photographers. But what will happen come November? Will Canon announce a second-generation 5D? I’d kind of like them to hold off on upgrading the 5D till next spring, and I recognize that I’m entirely biased when I say that.

Whenever they decide to upgrade it, here’s what I think will happen:

  • It will get the EOS Integrated Cleaning system
  • It will get Live View
  • The pixel count will go up, possibly to 16 megapixels, but not much beyond that. If they go up higher, the renowned low light sensitivity of the 5D will suffer. Remember, pixel pitch (the space that each pixel occupies on the sensor) has a lot to do with low light sensitivity. The more pixels you squeeze on that sensor, that harder it is to keep noise in check. The DIGIC III processor should help with this, and putting microlenses over each pixel should also help, but I don’t think the new 5D will get more than 16 megapixels. Keeping all this in mind, I’d really like the new 5D to be able to go up to 3200 ISO natively, and to 6400 ISO with expansion turned on.
  • The battery life will go up slightly
  • The body will get weatherproofing
  • The AF will get upgraded with the new system present on the Mark III cameras
  • Exposure metering will get more zones, possibly as many as the new 1Ds Mark III, or at least as many as the new 40D
  • Shutter durability will be increased to 300,000 cycles from 100,000 cycles
  • The LCD screen will be upgraded to 3 inches
  • The retail price will be around $3,300, just like with the previous model, and the street price will stick pretty close to that for the first few months after the launch

Meanwhile, the existing 5D cameras aren’t outdated by any measurement, and I look forward to using mine for a long time to come. It was a significant investment for me, and I’ll try to get at least 3 years from it before I upgrade.
