If you attach a EX, EX or EX II external flash unit to the Canon 60D, its internal infrared AF-assist illuminator is used instead of the flash head itself, providing a useful working range of about 50 feet with a less obtrusive light source. Without an external strobe attached, and when in Creative Zone modes Program, Priority, Manual, and Bulb , the internal strobe will fire its AF assist pulses if needed whenever the flash is raised.
It never fires in Movie mode, even before capture starts. Using Custom Function III-4, AF assist can be disabled altogether, set to fire from the external flash only, or set to fire with external strobes including an IR assist beam only.
You can also prevent the 60D from firing either the internal flash or external Speedlites altogether, by going into the Flash Control menu. This still allows the AF-assist pulses to fire; but without flash capability until you turn it back on. First introduced on the Canon Rebel XTi, Canon's system-wide approach to reducing the impact of dust on the image sensor is also included on the Canon 60D with a slight update to the anti-static coatings used.
A key feature of any SLR is the ability for the user to easily swap lenses. This expands creative options enormously, but every time the lens is removed, dust from the environment is free to enter the camera body. From there, it's only a matter of time before some of it makes its way to the surface of the sensor ,where it casts shadows that appear as dark blobs in your images. In truth, it's the anti-aliasing filter that collects dust, rather than the sensor itself, but common parlance refers to "sensor cleaning.
Every DSLR ever sold has offered a sensor-cleaning mode, in which the mirror is locked up and the shutter opened to permit the sensor to be cleaned with compressed air, a solvent-carrying swab, or other means. As the market has matured and more DSLRs have found their way into the hands of novice users, it has become clear that some automated way of dealing with sensor cleaning is needed. The principal approach other manufacturers have used to deal with dust has been to make the system self-cleaning, vibrating either the anti-aliasing filter itself or a protective cover glass lying above it, to shake loose adhering dust particles.
Once dislodged, a strip of sticky material at the bottom of the sensor cavity or mirror box catches and holds them. This approach was pioneered by Olympus, but has since been adopted by Canon, Nikon, Pentax, Panasonic, and Sony, in various forms. Some cameras use a dedicated piezoelectric element to provide the vibration, while others perform double duty with the sensor shift mechanism used for their image stabilization, with widely varying vibration frequencies and efficacies.
In addition, some manufacturers have adopted coatings on the low-pass filter intended to prevent dust particles from adhering in the first place. Dust reduction. The camera's Self-Cleaning Sensor Unit uses a piezoelectric element to shake dust particles off of the low-pass filter in front of the sensor.
The dust is then trapped by an adhesive strip along the base, preventing it from causing further nuisance. Cleaning is engaged each time the camera is powered up or shut down, or manually through the "clean now" function.
The second part of the cleaning system involves post processing with a compatible personal computer and the supplied Digital Photo Professional software. Via a menu option, the camera maps any stubborn dust spots that remain on the sensor after cleaning, saving their locations as Dust Delete Data that can subsequently be used to subtract the spots during post-processing.
A third option includes a manual sensor cleaning function which raises the mirror and allows users to clean dust that may have stuck to the low-pass filter. No matter how good an automatic cleaning system, there are going to be some stubborn dust particles that it can't dislodge. To deal with these, the Canon 60D has the ability to shoot a dust reference photo, and then transfer that information to Canon's Digital Photo Professional software, which can use it to eliminate the shadows cast by dust particles on the images.
The dust map "Dust Delete data" that the software uses to perform its magic is stored in the headers of files created by the camera.
There's thus no need to keep track of a separate dust image file, the information is always available in the file headers, assuming you've actually performed the dust-mapping process. You can update the Dust Delete data any time you think the camera might have been exposed to dust, or after you've manually cleaned the sensor.
Located in Shooting Menu 3, the Dust Delete Data option displays a screen that shows when the last Dust Delete reference image was captured. Selecting OK on this screen initiates a cleaning cycle, after which the camera prompts you to take a picture of a blank white surface.
The camera automatically defocuses the lens and sets the aperture appropriately, to produce the best possible dust image. The camera then processes this data, and reports whether it was successful or not. If the surface you used to capture the image wasn't sufficiently uniform, you'll get an error message, but if the image was good, you'll see a confirmation screen.
Despite Canon's advanced anti-dust technology, we feel compelled to point out that we've thus far seen no anti-dust system that completely eliminates the need for sensor cleaning. Sooner or later, you're going to need to clean your sensor, so we strongly recommend purchasing a good-quality sensor cleaning kit right along with your DSLR.
Automated anti-dust systems like Canon's will certainly help with some of the dust, typically the dust that the nylon brush-based cleaning systems can also handle. We ourselves use and recommend products from Copper Hill , which we've found to be both highly effective and among the most reasonably priced on the market. The 35mm equivalent range is about mm, because of the 60D's 1.
Sharpness is very good across most of the frame at 18mm, though there's moderately high chromatic aberration and some coma distortion visible in the corners. Corners are just a touch soft as well. Sharpness at full telephoto is quite good too, with excellent detail across the frame, though chromatic aberration is still a bit high.
All in all, this is a pretty sharp optic for a kit lens especially considering the zoom range, and the built-in image stabilization will come in handy for low-light or telephoto shooting. While chromatic aberration is a bit high, it is easily corrected with some post-processing. Well, there is a little distortion and vignetting, you can see parasitic images if you take a picture of a very bright light source, and its aperture is quite small.
But on the other hand we have a wide angle that is light and not very bulky, cheap, with a silent autofocus useful in video and which offers sharp images from one corner of the frame to the other. If you are a landscape photographer or if you want to take real estate photos, this is the lens to get for your your 80D. Drive System Lead screw and rack system driven by stepping motor Focal Length and Maximum Aperture: 10 18 millimeter, Weight: g Filter size: 77 mm.
It has an image stabilizer and its focus is fast and accurate. It can give much better results than the mm supplied as a kit. Dimensions: 9. You can also go on Youtube, type in the name of the lens you want and you should find plenty of test footage made with your Canon 60D and the specific lens you want. This will give you an idea of what equipment you will need to get. Also, if you plan to do a lot of travel videos or travel vlogs, take into account the total weight with the camera body and the lens.
You may also not want to risk damaging an extremely expensive lens. And finally, perhaps the most decisive point about choosing the perfect video lens for your Canon 60D will be if you want to have professional quality videos. More info. Skip to content. Some super versatile zooms cover much larger ranges, but they usually suffer in the sharpness, clarity, and aperture categories.
A landscape photographer might like to work from their car, which means they can carry enormous tripods and work with super-fast, large, and heavy lenses. Another photograph might like to shoot the same subjects, but backpack in and camp. That shooter may prefer a lighter and more mobile lens. All lens purchases are a balance between focal length, aperture size, and budget.
But in reality, manufacturers have yet to make that lens. Picking the right lens for any camera takes a little bit of time and introspection. What do you want to do with it, and how and where will you do it?
Do you get by with just one or two lenses, or do you have a bigger camera bag? Let me know in the comments. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.
I blog and publish articles about camera lenses here at lensguide. Check Price. This EF-S lens is made to fill that gap, with an equivalent focal length range of 16 to 29 mm. This is a beautiful L-series lens that is fast and dependable. Canon EF mm F4. A nice compromise is the EF mm zoom, which gives you to mm equivalent.
Several companies have adopted an interesting business model in recent years. Canon Lens Labels and Naming. When trying to complete your camera bag, what lenses are compatible with the Canon 60D? Picking the Right Lenses--EF vs. Understanding Sensor Size and Crop Factor. Are L-series Lenses Worth the Money? The key things you get when you purchase an L-series lens include the following. Do I need Image Stabilization lenses for the 60D? Finally, there are some special applications where IS is very handy.
Focal Length and Aperture Considerations. Before zoom lenses caught on, photographers used to carry three to four prime lenses. A 35 mm lens is considered a standard wide-angle. The most common use is for landscape photography. Of course, you can get much wider angle lenses, but anything wider tends to distort the image to some extent. The second most common wide-angle focal length is 28 mm. They render things more or less as they appear in real life.
The most common example of their use is for street photography, but you can use them for landscapes, portraits, still lifes, and nearly anything else. An 85 mm is a short telephoto lens, usually used for portraits. It zooms in slightly, which produces a flattering effect on your subjects. The background compresses slightly, which brings the image together into a cohesive composition.
A mm is another great short telephoto focal length. The last thing a photographer might want is a long telephoto lens, which would be mm or more. These are sometimes used in portraits, though they are more commonly associated with sports or wildlife photography.
