For those who are just starting out camera users, the understanding of the camera lens parameters may be relatively small, which requires more attention to this knowledge in general.So what are the camera lens parameters?Let's take a look at the next.

Camera lens parameters

1. Canon EF50mmf/1.2LUSM
Canon EF50mmf/1.2LUSM lens is designed with internal focus, which allows the lens body to be protected to the maximum during use.It has a large F1.2 aperture and thus a 72mm filter diameter and weighs 590 grams, but the design is very eye-catching and the lens is a good size for use with Canon full-frame bodies.The focus ring also has a soft and smooth feel and is very comfortable to hold in your hand.
The biggest highlight of the Canon EF50mm f/1.2LUSM lens is its large F1.2 aperture design and excellent focusing performance. F1.2 large aperture can bring unparalleled bokeh effect, excellent color performance makes the photos more detailed and vivid, and the lens is very soft out of focus, ideal for portrait.At the same time, the lens has a built-in high-speed CPU and a ring ultrasonic motor, which makes focusing very smooth, and in practice, you can hardly feel the bulkiness of a large aperture lens, so you can shoot any scene quickly.It can focus quickly and quietly when shooting any scene.
2. Nikon AF-SNikkor 24-70mm f/2.8GED
This Nikon AF-SNikkor 24-70mm f/2.8G lens, with its practical prime focal length and premium imaging performance makes this lens a must-have for full-frame DSLRs, and there are many colorists who equip it as a pendant head because of its superb practicality, making it a rare and excellent lens in full-frame.
As a constant aperture lens, the Nikkor AF-S 24-70mm/F2.8G is highly versatile on full-frame bodies, and the equivalent focal length of 36-105mm on DX format will do most shooting requirements.The lens also features Nikon's exclusive Serenity Flux motor, which allows for both fast and quiet autofocusing.Full-time manual focus is supported, allowing the lens to switch directly from autofocus to manual focus even in AF servo mode.
3. Sony FE24-240mmF3.5-6.3OSS
The Sony FE24-240mmF3.5-6.3OSS has built-in OSS optical stabilization to compensate for shake when shooting handheld and has some dust and water resistance. 5 aspherical lenses and 1 ED low-dispersion glass lens are used to effectively control image distortion and the effects of various phase aberrations on image quality.
Perhaps the only downside is that the lens has a maximum aperture of F3.5 at the wide-angle end to meet the outdoor and most of the light indoor shooting, but the longest focal length of F6.3 aperture value is slightly inadequate.So I recommend another lens that can be a good partner for the Sony EF24-240, a one-shot lens, and it is the Sony FE28mmF2 fixed focal length large aperture lens.
Compared to the FE24-240's longest end F6.3 aperture value, the Sony FE28mmF2 has a full 3.3 times more light throughput, even in dimly lit indoor situations with today's Sony full-frame digital cameras moving gor ISO6400 available high sensitivity easy to shoot pure and delicate works. 9 circular aperture. 3 aspherical lenses. 2 ED low dispersion lens trench configuration plusAt just over 2K, it's a good match for the Sony EF24-240.It's just right.

Camera lens profile

1. Clarity
Clarity refers to the clarity of the image of each fine shadow pattern and its boundary.Usually the resolution of 720P or more is called high-definition cameras.
2. Illumination
Illuminance refers to the degree of vertical illumination of the object, using the unit area of the accepted luminous flux to indicate that the unit of lux (Lux, lx), that is, lm/m2.
3. Electronic shutter
Electronic shutter is the use of electronic technology in time to control the generation and transfer of charge on the CCD chip, so as to get the shutter effect.Can be used with the lens to extend the range of camera sensitivity.
4. Strong light suppression
Strong light suppression is the use of DSP technology, simply means that the strong light part of the weakening, the dark part of the light, to achieve a balance of light.
5. White balance
White balance is a description of the display in the red.Green.Blue three primary colors mixed after the generation of an indicator of white accuracy.
6. Backlight compensation
Backlight compensation is the essence of the image according to the brightness, the appropriate adjustment of the camera gain and CCD charge accumulation time.
7. Wide Dynamic
Wide dynamic technology is in a very strong contrast to let the camera see the characteristics of the image and the use of a technology.
