Canon 60d vs 7d,
which is better? in my opinion, for better to use a Canon digital camera that suits your taste and the corresponding function. I chose the canon 7d because I need a sharper image. Before use it, i am using
Canon 60d. The
Canon EOS 7D is Canon's new semi-pro / enthusiast digital SLR and competes primarily with Nikon's recently updated D300s. It's a terrific SLR that shines in photo quality, control placement, speed, and viewfinder size and coverage.
First, let me tell you a little about myself so you can gauge what my expectations for the camera are. I'm strictly a hobbyist photographer and use my camera a couple of times a month at museums, outdoor parks, and vacations. Besides photos of my dog, my photography consists primarily of static subjects. This is my second SLR.
Enough of me, onto the camera. The 7D is a fairly bulky SLR and dwarfs "entry level" models such as the Olympus E-510 (see my photos), though it's no bigger than Nikon's D300s. With that said, it's not uncomfortably large and is easy enough to carry around all day. Build quality is terrific and the camera has a solid, luxury feel to it. The 7D fits very well into my average sized hands and, with the kit 28-135 lens, is nicely balanced. All the buttons are easy to reach and, if you've used a Canon camera before, easy to figure out. The magnesium body is sealed against moisture and dust. The shutter button is well placed and has a nicely defined halfway point. A control dial is on the back of the camera and behind the shutter button too. There is also a joystick-like toggle on the back of the camera as well.
A large (3") and high-resolution (920,000 pixel) screen is on the camera back with a secondary status LCD display on the top (with backlight). The screen is a pleasure to use when reviewing images for focus, and when manually focusing in magnified live view mode. Compared to the 3-inch 420,000-pixel screen on my Panasonic LX3 it's a definite upgrade, and makes a noticeable difference.
The viewfinder is huge and bright and has 100% coverage. Coming from the Olympus, which has a very cramped and tunnel-like viewfinder, it was a revelation, and was one of the reasons I decided to step up to the 7D. Also, by using a transmissive LCD on the viewfinder the only markings you see until you confirm focus are for the selected focus method (for instance, a single box when using one focus point, or brackets when using the auto select autofocus method). Moreover, a composition grid can be imposed on the viewfinder. The information display on the bottom of the viewfinder is large and bright and contains lots of shooting and camera information.
The camera is very responsive and turns on almost instantly. The sensor cleaning occurs when you turn the camera on or off but can be interrupted during power up. Focus speeds with the kit lens are very speedy, even in dim light (two 40 watt lamps and a television as the only light sources in a 17' x 11' room). The 19-point all cross type autofocus is uncanny at picking the correct subject. If it doesn't get it right the first time it will the second. I usually set all my cameras to center point autofocus, but the 7D does a great job picking out the subject, so I leave it on fully automatic mode. Live view focusing is not a quick, especially in low light, and I only use live view when I need to shoot at a weird angle and I can't shoot looking through the viewfinder. Live view can be used with a mirror flip or contrast detection. The contrast detection mode is fairly pokey, while the mirror flip mode is quicker, but introduces a brief break in the view. Continuous shooting is available in both a high and a low setting. High is 8 FPS, while the low speed is 3 FPS. The shutter sound is nicely subdued and not nearly as noisy as the Olympus' is.
Photo quality is terrific. There are various Picture Styles you can choose to alter the contrast, sharpness, color tone, and saturation of the photos. At any rate, 99% of the time, colors are natural, exposure is accurate, and dynamic range is great. At this level of camera, that's expected though. What I really love about the 7D is the high ISO noise, or lack thereof. The luxury of feeling confident while shooting at high ISO is priceless. I've taken a good number of shots as high as ISO 3200 and have no complaints. Of course there is a bit of noise, and the mushiness that noise reduction brings, but for an 18 MP image at ISO 3200, I have no complaints. The ISO speeds above 3200 are OK as well, but I'll reserve those for emergency use only, they get fairly processed looking. The relatively large APS-C sensor not only allows for low noise, but also allows me to produce nicely blurred backgrounds and great depth of field. I couldn't achieve the same degree of that effect with the smaller 4/3 sensor in the Olympus, and I certainly couldn't do it with my point and shoot cameras unless I was in macro mode. There is an Auto Lighting Optimizer feature that attempts to correct photos that are not correctly exposed (e.g. subjects are too dark or highlights are lost). It works well for the most part, but, depending on the subject, the differences are very subtle.
The HD movie mode is nicely done as well. You set your focus, either automatically or manually, before you start recording. You can refocus during recording but you'll definitely notice it. You can adjust shutter speed, aperture, and ISO in manual movie mode as well. There is a monaural microphone on the front of the camera, or you can plug in a stereo microphone. By pressing the shutter button, you can interrupt the movie briefly to take a still photo, similar to Canon's S series super zoom cameras.
The kit lens is nicely constructed and fairly sharp from corner to corner. Purple fringing is not much of a problem in my photos. The field of view is kind of narrow though. The lens starts at 44.8mm with the 7D's 1.6x field of view crop factor taken into account. Without a wide angle it's not an ideal all around lens, but I do feel it's worth the extra money for the kit with this lens. You end up getting a nice, ultrasonic motor, image stabilized, 4.8x lens for a minimal cost.
The only things I don't like about the camera so far are that in auto ISO you can't limit how high it goes. I find the 7D wants to jump up to ISO 3200 fairly quickly in low light when it doesn't need to go nearly that high. When it jumps to ISO 3200 I find I can dial it down to ISO 1600 manually and still get an acceptable shutter speed, so the Canon is being very cautious jumping up so high. The other thing I'm not fond of is the fact that when you're in playback mode the most you can zoom out is a 9-image grid. With such a large high-resolution screen I would appreciate an index grid playback mode that showed more photos. Lastly, I find the process for setting the custom white balance a bit long winded. You have to take a photo of a white reference object then go into the menus to choose that photo as the reference photo. On other cameras, even Canon's point and shoots, the process is much faster, and it doesn't save the reference photo to your memory card. It's not the worst system, and I have become very quick at it, but it could be better.
