The Canon 50mm f/1.2 was very sharp, quick to focus and produced buttery smooth bokeh for half-body and portrait crops. It also produced a lot of unwanted chromatic aberration when shooting against a blown out background. This is rather disappointing for a lens of this price.
In the same way What is aperture and sensor in camera and their work in camera?
Aperture controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as an f-number (written as “f/” followed by a number), such as f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32.
Subsequently, Are L lenses worth it? Better Build Quality. Canon’s L-series lenses have better build quality than their non-L counterparts. The higher quality optics mean they’re bigger and heavier (the 50mm f/1.2L weighs 1.28lbs while the 50mm f/1.4 weighs 0.64lbs); they also use premium materials.
What does 1.2 mean in lens?
1:2 is the same as f/2.0 or f/2. Also commonly referred to a the f-stop. It is the widest aperture your lens is capable of. Smaller numbers denote a faster lens, and generally faster lenses are more versatile because they allow you to take pictures in lower light situations.
Which shutter speed is faster?
Shutter speed is expressed in units of time: fractions of a second or several seconds. A higher (or faster) shutter speed allows less light to hit the camera sensor or film strip (if using an analog camera). Conversely, a lower (or slower) shutter speed allows more light to pass into your camera.
What shutter speed should I use?
As a rule of thumb, your shutter speed should not exceed your lens’ focal length when you are shooting handheld. For example, if you are shooting with a 200mm lens, your shutter speed should be 1/200th of a second or faster to produce a sharp image.
What does l mean Canon?
What is the Canon “L” Lens Series? Good question – and many answers exist, but it is Canon’s professional line (though used extensively by non-professionals) of EOS EF autofocus 35mm SLR and DSLR still camera lenses. Some say L stands for “Low Dispersion” – achieved by the UD lens elements found in these lenses.
What does the red ring on Canon lenses mean?
If the lens has a red line, the lens is part of Canon’s L series. The L stands for luxury and these are the crème de la crème of Canon lenses. L series lenses feature top of the line optics and build quality making the most coveted and expensive of the Canon lenses.
Are STM lenses worth it?
The STM version is better because it has faster, smoother AF, and the front element does not rotate. The optics are also improved which gives you better image quality. The STM focus ring is active during Auto Focus and you can small manual adjustments to focus.
What is aperture in photography?
What is aperture in photography? Aperture refers to the opening of a lens’s diaphragm through which light passes. … Lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures.
What does F 1.2 mean on a camera?
A lens with a wide aperture is also known as a “fast” lens, because it enables you to use a faster shutter speed. If you’re shooting at f/1.2, there is a lot of light entering the lens – which means that the shutter doesn’t need to be open for as long to expose an image.
What is the biggest difference between a film camera and a DSLR?
The sensor: The most obvious difference between film and digital is the sensor used to take the photo. With film cameras a film sensitive to light is placed behind the lens. … With digital cameras a fixed electronic sensor (sometimes known as CCD) is situated behind the lens.
What happens if shutter speed is too high?
What happens if your shutter speed is too fast? … In general, the faster your shutter speed, the more it will freeze motion—and the degree of frozen motion will depend on how fast your subject is moving. For example, a walking dog can be frozen at 1/100 second while a running dog might need 1/800 second or faster.
What is the best ISO setting for portraits?
For portraits, you want the highest image quality possible. So for the ISO set it as low as you can to avoid excess noise in your photos. Go for somewhere between ISO 100 and 400. But having said that, you also need to maintain a usable shutter speed.
Does shutter speed affect sharpness?
Shutter speed can affect the overall sharpness of an image, as well as more localized sharpness on the subject.
What shutter speed is best for portraits?
However, for most traditional portraits, it is best to use a fast shutter speed so that you can capture the moment without any blur. A typical portrait during the daytime without using flash is best taken with a shutter speed of at least 1/200th of a second handheld or 1/15th of a second on a tripod.
What is best aperture for portraits?
Portrait photographers prefer wider apertures like f/2.8 or even f/4 — they can focus on the subject and blur the background. That’s also why landscape photographers typically shoot in the f/11 to f/22 range — they want more of the landscape in focus, from the foreground to the distant horizon.
Are Canon L series lenses weather sealed?
Canon’s L series line of professional lenses are hard to beat, and the 24-105mm f4 L IS USM is a firm favorite with the Canon crowd; and for good reason. This lens is built like a tank, it’s weather sealed, and the image quality is superb.
Why Canon lenses are white?
“There is a good reason for this,” Canon writes over on its European website. “Lenses contain glass elements. … “But large lenses contain large elements and here expansion can bring a lens close to the limits of its design tolerances. A white surface reflects sunlight, helping to keep the lens cooler.”
What does F 4l mean?
f/4 is its maximum aperture. L means it’s part of Canon’s premium range of lenses, because it’s built to pro standards, uses special glass elements and can cover a full size film frame or sensor. USM is ultrasonic autofocus, meaning basically it’s fast, quiet and accurate.
What does STM mean on Canon lenses?
STM – Stepper Motor designed to minimize autofocus vibrations and noise during video recording, this autofocus motor has been gradually making its way into budget Canon lenses.
What does USM mean on Canon lenses?
USM (Ultrasonic Motor) is the most widely used AF motor type in the Canon EF lens range to date. Common to all USM motors is the fact that that they convert ultrasonic vibration energy into rotational force to move the lens.
What is the difference between USM and STM?
USM lenses are more professional-grade and better for shooting photos, while STM lenses are geared more towards amateurs and better for video. … Their focus speed, while a tiny bit slower, is also better suited for video as it is smoother and less “jarring”.
