Canon 650D vs Canon 600D, take a look at 650D specification comparison review and share your thought with us,
Canon 650D image sensor
Canon 650D uses 18MP APS-C Hybrid CMOS sensor with phase and contrast detection AF system, enables faster and more precise autofocus compared to 600D, you also get standard ISO range up to 100 to 12800, and expandable up to 25600.
Canon 650D image processor
New Canon DIGIC V Image processor: The New image processor used in Canon 650D improves the overall speed & response time of camera, It increases the Continuous shooting speed up to 5 fps and creates less noise in your JPEG images compared to 600D, the fast DIGIC V image processor also enables the camera to perform sophisticated functions such as in camera HDR Backlight Control, NR mode, art filters, lens correction and much more.
Canon 650D AF sensor
New dual AF system: Canon 600D takes lot of time to do AF when Live view is on and No AF is available during movie recording, the 650D comes with improved Hybrid phase and contrast detection AF system, It also offers Continuous AF during Video Recording, Touch Focus and Touch Click Technology, see more details below
There are four different methods of AF available during live view shooting:
Face Track mode detects a face, and continuously focuses and tracks it by switching AF points even when the subject moves to a side profile; FlexiZone – Multi AF divides the scene into 31 AF points prioritizing the centre and subject in the foreground; FlexiZone – Single AF mode and Quick mode, allows the focal point to be changed by touching the exact area on the LCD. Continuous (Pre) AF mode, subjects will always be in focus even before the shutter is activated for improved focusing speed. What’s more, users will be able to perform familiar multi-touch gestures (pinch, spread and swipe actions) to zoom in and out of shots, view images and flip pages.
Canon 650D AF is approx 2X fast compared 600D during live view mode: Conventional contrast-detection focus works by shifting focus back and forth until the peak contrast is detected; the new Hybrid CMOS AF System improves this by predicting the subject’s location and approximate focus using phase detection, which makes auto-focusing twice as fast when the subject is in the zone (approx. middle of the frame).
Continuous AF during Video Recording: Yes its true, Canon 650D can do Continuous AF during Video Recording, the Rebel T4i features Canon’s new Movie Servo AF providing a quiet, continuous AF during HD video recording when using one of Canon’s newly introduced Stepping Motor (STM) lenses. The silent continuous autofocus when shooting HD video helps ensure the camera only captures the sounds of the scene being recorded.
Improved Imaging Performance Features: The EOS 650D helps novice photographers capture great images and video, even in low-light with a range of new performance features:
Handheld Night Scene mode
HDR Backlight Control mode
Multi-Shot Noise Reduction
Handheld Night Scene and Multi-Shot Noise Reduction captures 4 images rapidly and combine them into one blur and noise free image.
HDR Backlight Control captures images at three different exposures – under, correctly, and over-exposed – and combining them into one HDR image displaying both highlight and shadow detail.
Video snap-shot mode of canon 650D is similar to Canon 600D, nothing new.
Touch screen with 650D: For the first time canon Rebel comes with touch display, EOS controls are integrated into an intuitive 3-inch Vari-Angle Clear View LCD II Touch Screen Monitor
New STM Lenses for movie recording
The new EF-S18-135mm f/3.5-5.6 IS STM has been developed to improve movie-shooting capabilities with improved image quality throughout the entire zoom range and silent, seamless focusing. The new stepping motor drive delivers ultra smooth and precise focusing during movie recording with continuous auto-focus. Coupled with the Movie Servo AF in the EOS 650D, the camera’s built-in stereo microphone will not pick up any focusing noises while shooting scenes that require silence, and a zoom ring lock to prevent users from accidentally changing the zoom in the middle of a shot, or extend when the lens is left in a bag.
Conclusion:We have done a specification comparison review of 600D vs 550D a year ago, the 600D was a minor upgrade over 550D and we have recommended our users not to upgrade or buy 600D DSLR if you are a still shooter,
For Canon 600D users: Buy it! Hybrid CMOS sensor, Full time AF during video & live view mode, Multi-Touch vari-angle display, DIGIC V image processor that gives you 5fps of Continuous shooting speed, Canon 650D also comes with In camera HDR, Multi-frame NR mode and Handheld Night Scene mode, It’s a big change over 600D.
For 550D users: Yes, we highly recommend you update your 550D with 650D, its really a big Jump over technology.
According to MTF chart the lens produces sharp images + nice color & contrast at center of the lens at MAX aperture and sharpness decreases when we move towards the corner of the lens, overall the MTF chart of Samyang 8mm f/2.8 lens is very impressive.
It gives an immersive field of view – 180 degrees, with a 12mm 35mm equivalency. True diagonal fisheye lens for APS-C format, meaning that the image it produces fills the frame on APS-C cameras. As with all current Samyang lenses it is manual focus only.
The optical construction of the lens is 10 elements placed in 8 optical groups including one aspherical and two ED elements. The aperture consists of six diaphragm blades with apertures available from f/2.8 to f/22. It has an Internal focusing system which means the lens form does not change in size when focusing. Additionally, the Samyang 8mm fisheye features the latest generation multilayer anti–reflection ultra multi-coating (UMC) to minimise flare and ghosting. The integrated lens hood also helps to reduce flare from behind the lens.
Due to the very large depth of field produced by such a small focal length lens, focus can be easily achieved by simply setting the approximate distance on the lens scale. Setting the lens to around 1m at f8 will produce images that are sharp from very close objects to infinity. As with all manual focus lenses for critical or in very close focus situations you can use Live-View to fine-tune the focus manually.
The Samyang 8mm f/2.8 fish-eye lens is also capable of producing panoramas and 360 virtual tours, including full 360 degree images.
Fisheye lenses are also popular for special effects use where distortion, exaggerated perspective, or extreme depth of field are desired.
This lens offers superior optics and exceptional value for money.
Samyang 8mm 1:2.8 UMC fish-eye is available in either a black or silver finish
The Marmalade, a special effects studio in German has developed a super versatile robotic arm called “Spike”, the extremely fast robotic arm captures videos by holding a ultra high frame rate video recorder, stunning videography I’ve ever seen….enjoy the video below
Our groundbreaking High Speed Motion Control System ‘Spike’ brings the creative freedom of a moving camera to the world of high speed filming and so enables us to create shots that would be impossible to achieve otherwise.
‘Spike’ can freely move the camera with unparalleled speed and precision, thereby removing the previously existing creative limitation of having to shoot high speed sequences with a locked camera.
By marrying the hardware of a sturdy and reliable industrial robot to software that was built from the ground up for the demands of motion controlled high speed imaging, we developed a unique system for creating real life camera moves with the ease of use normally associated with 3D Animation.
Exactly repeatable camera moves can be created and modified within a matter of seconds. Using the rich previsualisation features of the system, creative options can be quickly explored on the computer screen and the resulting changes then immediately be performed for real. Additional effects can be triggered in sync with the move, allowing complex effect sequences to be performed.
And of course ‘Spike’ also is at home at slower speeds, producing dramatic product shots as well as stealthy perspective changes and breathing life into pack shots.
