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.

Lens review: Canon EF 24-105mm f/4L IS USM Zoom Lens

I’m going to talk about the Canon EF 24-105mm f/4L IS USM Zoom Lens in this review. It’s a wonderfully versatile L series zoom with surprising image quality and great image stabilization built right in. I’m also going to show you lots of photos I took with this lens, to illustrate the various points I’m about to make.

If you’re interested, I also wrote a comparison of this lens and the EF 24-70mm f/2.8L zoom. It might help you decide which lens to get if you’re interested in purchasing either of them.

EF 24-105mm f/4L IS USM Zoom Lens

So, that’s the lens, right there on my table. It’s not as tall as my 100mm macro, but it’s also heavier, which is to be expected. There’s a lot more glass in zoom lenses. When you turn the zoom ring, the barrel extends outward. There’s some zoom creep, but that’s pretty much a “feature” on all zoom lenses I’ve tried, including other, more expensive zoom lenses.

I found its range to be just what the doctor ordered. At the wide end, the 24mm is great for landscapes or other interesting compositions, like you’ll see below, and at the tele end, 105mm is great for portraits and for bringing in distant details. Believe me, there’s a ton of difference between 70mm and 105mm when you’re trying to focus on some distant object. That extra reach is great! (By the way, I just dropped a hint in this paragraph. Did you catch it? It has to do with the 24-70mm f/2.8L zoom… There’s a review of it coming soon.)

The photo below was taken at 24mm after sunset, on a tripod.

Dusk

This one was taken from the same spot, but at 105mm. See how versatile the focal range really is?

Dusk II

I mentioned something about interesting compositions at wide angles above. Here’s one:

Goaty

I had doubts about this lens. After all, the 24-70mm L series zoom costs the same, yet it has no image stabilization and the focal range is shorter. How could a lens that packs in a longer focal range plus IS be as good as the other and at the same price? Let’s not also forget that Canon offers this lens as a kit lens for the 5D. Granted, it is an L series, but still… right? Well, prepare to be surprised.

I went to downtown Bethesda at night, and shot handheld, with the IS turned on. Keep in mind that the widest this lens will go is f/4.

Crenels

The photo above was taken at a shutter speed of 1/15th sec, handheld. At 1:1, those crenels are still sharp. But wait, that’s not all… The photo below was taken at a shutter speed of 1/8th sec — I propped my elbows on a balustrade to take it:

Arches

The details here are even sharper than in the previous photo. In my book, this means the lens is great in low light for a zoom. Nothing can beat my 24mm or 50mm primes at f/1.4, but there’s no mistaking the fact that the IS built into this lens does a great job of compensating for the smaller maximum aperture.

What about the contrast, sharpness and bokeh, you ask? Well, let’s look at a few photos:

Tiled

The photo above was taken at close range, almost macro range. I believe I switched to manual focus when I took the shot. I was so close the AF stopped working. I did very little post-processing to the shot, and certainly didn’t alter the colors. The lens plus the camera did most of the work, including enhancing the colors present on that old barn. Having been there in person, I know the colors were more faded.

Here’s another photo taken at close range:

Waking up to this

Look at the photo of the cat below. When I downloaded the photos from my 5D and looked at it, I was struck by how 3D it felt. The sharpness is all there, even at 1:1, the contrast is beautiful, the colors are great. That’s when it hit me: this lens is really good!

Mr. Whiskers

Let’s talk bokeh. Every lens has its approximate sweet spot when it comes to it. Stray from that proper distance to focal range ratio, and the bokeh looks all screwed up. Some lenses are better than others, and produce great bokeh across a larger focal range. I think this is one of those lenses. The bokeh isn’t entirely creamy, like you’d get with a fast prime opened up all the way — remember, it can only open to f/4 — but the bokeh’s there, and it does its job, which is to bring out the subject and fade out everything else pleasantly. Have a look at the photos shown below, and you be the judge:

Thingamajig

Lily

Blackberries

I really appreciated its versatility. I love my primes, but let me tell you, there’s nothing more annoying than missing a shot because I have to switch lenses. Primes are great for controlled conditions — nothing beats them there — but when you’re out and about, you don’t want to be futzing around in your camera bag, looking for your lenses, while your photo op passes by.

Have a look at these next few photos. It felt great not to have to switch lenses and still be able to take all of them.

Lazying about

This is one lens that does not disappoint. It’ll likely stay on your camera body for 70-80% of the time. It’s an L series, so you know it’ll perform over a long period of time. It’s lighter than other L series zooms with similar focal ranges, and the image stabilization works just as I’d expect it. If you’re in the market for one, buy it.

Lens review: Canon EF 70-200mm f/2.8L IS USM Zoom

Canon EF 70-200mm f/2.8L Zoom Lens

I rented Canon’s premier mid-range zoom lens, the EF 70-200mm f/2.8L IS USM, and had the chance to play with it for a day. I put it through its paces: daylight, dusk, low light and early morning light. The result: I love it and plan to buy it. This lens works better for my needs than the EF 100-400mm F/4.5-5.6L IS USM, which I rented and reviewed recently.

Created beauty

Oh, I rented the EF 1.4x II Extender along with this lens as well, and it worked great. It’ll decrease the aperture from f/2.8 to f/4, but I didn’t find that to be too much of a problem, even in lower light, while shooting handheld. I simply boosted my ISO and switched to Shutter Priority, to make sure my shutter speed stayed above 1/60th of a second.

Deposit

On a full-frame sensor like my 5D, I got exactly 70-200mm, and 98-280mm with the aid of the 1.4x extender. On a cropped sensor like that in the 30D or the Rebel, you’ll normally get 112-320mm, or 157-448mm with the extender. Those are pretty nice ranges indeed.

Slanted

Even though I shot mostly handheld, and for most of the time, in fairly low light (thick forest, ground-level), the image stabilization built into the lens worked great, even with the extender attached. I was able to get clear shots while keeping the shutter speed even below the focal range of the lens. We probably all know about that simple rule of thumb of keeping the shutter speed equal to the focal length, right? Well, I was able to get crisp shots at 1/80 while the focal length was over 100 mm and more. For example, the shutter speed of the photo enclosed below is 1/100 while the focal length was 150mm (with the extender attached). Still, the photo is plenty sharp at 1:1, and that’s pretty good to me.

Taking a break

I have only praise for this lens. It works great! I love the short travel of the focal length selector. It’s amazingly short given the large focal range. I love how crisp and sharp my photos come out. The bokeh is great. The lens handles just like it should, and autofocus times are pretty small. But, it is heavier than the 100-400mm zoom. A LOT heavier. You won’t realize just how heavy it is until you go out there and use it for a couple of hours. Your biceps will get a workout!

Harried hare

I plan to buy it at some point in the future. At $1,500-1,600, it’s not cheap, but it sure is great!

Lens review: Canon EF 100-400mm f/4.5-5.6L IS USM Zoom

Canon EF 100-400mm f/4.5-5.6L IS Zoom Lens

I had a chance to play with Canon’s affordable 100-400mm L series zoom last week. I rented it for a day from Penn Camera at Tyson’s Corner, mounted it on my 5D, and ran out to chase wildlife as soon as I got home from work. As the sun began to set, I took it up to the roof, set it on my tripod, and took photos of the horizon. In the morning, I snuck out onto the terrace at sunrise and got photos of that as well. All in all, I put the lens through its paces, shooting in daylight, dusk and dawn conditions, handheld and on a tripod. Even though I only used the lens for a day, albeit a pretty full one, I’m fairly comfortable with what I’m about to say.

I liked it. The 100-400mm range is a versatile range, and the fact that you can get this L series lens at around $1,400 makes it a bargain. The lens isn’t as heavy as the 70-200mm L series zoom (which I played with today), and it’s fairly comfortable to hold for moderate amounts of time. It has a push-pull mechanism for extending the focal range, and that has its benefits and drawbacks. The benefit is that it does make it a bit easier to get through the large focal range a little faster. It’s also necessary in order to make the lens affordable. Push-pull lenses are cheaper to make than regular zooms, and require less glass as well, making them lighter.

➡ Updated 7/4/07: Erik Persson asked me two relevant questions this morning via private email. One is about how the autofocus handled, and the other was about whether autofocus is possible at all with an extender, or whether manual focus needs to be used. Autofocus was a bit slow, but that’s to be expected. This is a big zoom that can focus over a large distance. There is a focus limiter switch that decreases the focusing distance. You tell it to focus either from 1.8m to infinity or 6.5m to infinity. If you know you’re only going to shoot things farther away than 6.5m from you, then set the switch to that, and the autofocus will be a little faster. I’m not sure how to answer Eric’s second question. He suggests autofocus on EOS models up to the 5D is possible only up to f/5.6, and Mark 1D models can autofocus up to f/8.0. Not sure about that. I can only point you to this lens chart at Canon, which talks about the compatibility of the extenders with various lenses, and tells you what the expected aperture will be, and whether or not autofocus will be possible at all. I checked the specs for the 5D and 1Ds, and can’t find the upper f-stop limits for either models. Perhaps a call to Canon will clear this up, but it is the 4th of July today, and I doubt they’re open. Maybe one of you who has more information is willing to comment on this.

Beautiful swallow

Ugly one awaits

➡ Updated 7/6/07: Erik got back to me once more with a link to a review by The Digital Picture, where the AF to aperture specs are discussed. Furthermore, he provided a link to specs from Canon for the EOS 1v SLR (film camera) where the bit of information about being able to use AF with lenses that only open to f/8 is provided. So it looks like you’ll have to use manual focus if you stick extenders on the 100-400mm zoom. Thanks Erik! You know, you could just as well use the comments instead of sending me emails, but whatever works for you. 🙂

If you’ve been looking at the 400mm f/2.8L tele, which retails around $6,500, and you’re wondering why this lens is so inexpensive, you should know there is a reason for the price difference — but I doubt you needed me to tell you that. I stated the reasons in the paragraphs above, and they are: less glass, push-pull mechanism for the EF 100-400mm zoom lens. I haven’t tried out the 400mm tele myself yet, but I have a feeling it’s a great deal sharper and has more contrast than this lens.

Early morning contrails

Clarity

I think you can already guess what my two complaints are: the details are a bit soft when the photos are viewed at 100%, and the push-pull mechanism creates a sort of vacuum between the camera and the innermost lens. Every time I extended or contracted the lens, air rushed in or out through the crevices. I’m sure things are isolated pretty well and dust doesn’t get sucked in, but it feels odd, and it makes it difficult to stop at say, 300mm. It’s certainly a lot easier to either pull the lens all the way out to 400mm or push it all the way back in to 100mm. You know how they say that zoom lenses are soft at either ends of the focal range? Well, it would have been nice to have some sort of limiter switch that could let me stay between 110-390mm, or something like that. With the push-pull mechanism, it was hard to get the focal length just below or above its limit in order to avoid softness.

Having said all this, let me reassure you that this lens is a bargain at its price. If you’ve had your eye on it, get it. Realize you won’t get the results you might get with a more expensive tele, but you won’t pay through the nose for it either. This lens will definitely shine on cropped sensors like those found in the 30D and Rebel, where the effective focal range will be 160-640mm. How else can you get in the 600mm focal range without spending a ton of money? What’s more, with extenders like the 1.4x or the 2x, you can get up to 800mm on a full sensor or up to 1260mm on a cropped sensor. That’s pretty amazing!

Afternoon traipse

There are a few other things to keep in mind though. The maximum aperture at 400 mm is f/5.6, and that means you’ll need pretty good light in order to shoot handheld with it. If you stick an extender on it, the effective aperture will get even smaller, so you’ll either need serious daylight or a tripod. But, as I’ve already said, you get amazing range with this lens, and it’s inexpensive for an L series zoom. If you’re willing to live with the few issues I’ve outlined, then get it.
