Sve je to OK, ali mislim da je EOS 650D zreo za potpuno novi senzor, ovaj podgrejani 18MP je aktuelan vec par godina, a to je u danasnje vreme dovoljno.

The New EOS Rebel T4i DSLR Camera Puts the power and creativity of DSLR Stills and Video at your fingertips
Silent and Continuous Autofocus in Video, The EOS Rebel T4i Lets People Re-Live Magic Moments Through Stunningly Crisp Video and Incredible Stereo Sound

LAKE SUCCESS, N.Y., June 8, 2012 – Canon U.S.A., Inc., a leader in digital imaging, today announced a new flagship model in its most popular EOS Rebel line, the Canon EOS Rebel T4i Digital SLR Camera. The new EOS Rebel T4i features incredible image quality with an 18-megapixel CMOS (APS-C) sensor, DIGIC 5 Image Processor that helps capture all the action with high-speed continuous shooting of up to five frames per second (fps) and an extended ISO range of 100–12800 (expandable to 25600 in H mode) that gives photographers the opportunities to take the EOS Rebel T4i into more shooting situations than ever before.

The camera includes a revolutionary new autofocus (AF) system to help achieve fast, sharp focus and smooth HD video. The new AF system includes a nine-point all cross-type sensor array, and new Hybrid CMOS AF which achieves fast focus when shooting stills or video in Live View mode. Much to the pleasure of aspiring student filmmakers and parents everywhere, 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. When combined with the camera’s new Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II and intuitive “fingertip” controls, touch-menu and advanced still and video capabilities, the EOS Rebel T4i stands as Canon’s most “consumer-friendly” DSLR to date.

“Our Rebel line of cameras bridges the gap between the casual photographer and someone looking to advance their photography and capture moments in new and creative ways. The EOS Rebel T4i boasts full HD video with AF and touch-screen navigation, inspiring even more photographers and videographers to explore the creative options made possible with DSLR cameras and lenses,” said Yuichi Ishizuka, executive vice president and general manager, Imaging Technologies & Communications Group, Canon U.S.A.

New AF Capabilities

One of the most significant upgrades to the EOS Rebel T4i is a dramatically upgraded AF system including a nine-point all cross-type AF array, with a high-precision dual-cross f/2.8 point at center. The EOS Rebel T4i is the first Canon camera to feature the new Hybrid CMOS AF system which increases AF speed by reducing the camera’s need to “hunt” for focus. The result is fast continuous AF when shooting photos and movies in Live View. Because the camera’s cross-type AF points have two-dimensional contrast detection, the EOS Rebel T4i provides highly accurate focus regardless of your shot composition and ensures great focus no matter where the subject is located in the frame. The addition of the dual-cross point in the center allows for much faster and precise focusing for photographers using high-speed f/2.8 lenses.

Using the touch panel, parents can select their child on the LCD screen and the camera will remain focused on that child while they stay in-frame, ensuring sharp focus in crowds and group shots. The new AF system enables Touch Focus for shooting photos and movies in Live View. To make capturing photos even easier, a Touch Shutter function can also be enabled, whereby selecting a subject on the LCD screen, the camera will instantly take a photo, once focus is locked.

Continuous AF during HD Video Recording

For the first time in a Canon EOS DSLR, the EOS Rebel T4i includes Canon’s new Movie Servo AF for recording video. When used with Canon’s new EF and EF-S STM lenses, the camera can provide smooth and quiet continuous AF while recording video. This technological breakthrough enables the new EOS Rebel T4i to achieve AF while still retaining a DSLR camera’s signature background blur and image quality, producing stunning videos of parties, events, summer vacations or graduations.

When shooting video with Canon’s STM lenses, AF also remains silent, helping ensure you only capture the sound of the scene being recorded. The EOS Rebel T4i features a built-in stereo microphone, a first for the Rebel line, that includes an attenuator function to reduce audio distortion in extra loud situations.

Canon’s First Touch-Screen DSLR

Another Canon first, the EOS Rebel T4i includes a best-in-class Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II featuring 1.04 million dot resolution for unparalleled, clear viewing. The electro-static touch-panel screen is the most advanced that Canon has released to date with multi-touch capabilities allowing photographers to use familiar gestures such as “pinch-to-zoom” and “swiping” to scroll between pictures. Camera operation has been simplified through this feature allowing for Touch Focus or Touch Shutter controls via the vari-angle touch-screen. The vari-angle touch-screen flips out to the left and rotates 180 degrees forward and 90 degrees backward, making tough above-the-head and low-to-the-ground shots easy, and allowing improved views during photo or video capture. That means the overhead shot taken in a crowd or at a graduation march just got a little easier to shoot.

Improved Imaging Performance Features

The EOS Rebel T4i helps novice photographers capture great images and video, even in low-light with a range of new and upgraded modes

• Handheld Night Scene

• HDR Backlight Control

• Multi-Shot Noise Reduction

• Video Snapshot

• Scene Intelligent Auto

Canon’s new shooting modes (Handheld Night Scene, HDR Backlight Control and Multi-Shot Noise Reduction), take multiple pictures, an d combine them – in camera – to help capture a wider dynamic range, minimize the image grain or noise, and produce more vivid colors so landscapes and city scenes are as breathtaking as when seen in person.

Families have enjoyed coming home from a vacation or outing with a fun, short Video Snapshot highlight reel shot on their Canon camera to share the full story of their adventure. Now with the EOS Rebel T4i users will also have the option to delete, cut or re-order the clips before exporting the Snapshot album to post or share.

Canon’s Scene Intelligent Auto mode – the “green” mode on the dial – analyzes the scene being shot, taking into account faces, colors, brightness, movement and contrast, to select appropriate camera settings and help produce the best possible image. This mode has been enhanced to deliver the best possible exposure, particularly when shooting in low-light.

New STM Lenses and Accessories

To leverage the unique, new shooting functions of the EOS Rebel T4i, such as EOS Full HD Movie with continuous AF, Canon is introducing two new unique lenses, the new EF-S 18-135mm f/3.5-5.6 IS STM lens and new EF 40mm f/2.8 STM lens. Both new STM lenses includes Canon’s new Stepping Motor technology, which allows the lenses to smoothly and silently focus, and when used in combination with Canon’s new EOS Rebel T4i Movie Servo AF feature, achieve continuous AF while recording video. The new stepping motor technology in both lenses quietly focuses allowing the EOS Rebel T4i’s stereo microphone to only record the sounds of the scene being shot.

The versatile EF-S 18-135mm f/3.5-5.6 IS STM lens offers the right combination of size, weight, image stabilization and focal length, allowing photographers to capture wide-angle or telephoto photographs and video. This lens is a great option for photographers who may only want to carry one lens with them for both wide landscapes, and close-ups. Appearing for the first time in a Canon EF lens is Dynamic IS (Movie Shooting Mode only) that uses a wide image stabilization correction range to help ensure steady video even when shooting while walking.

The new EF 40mm f/2.8 STM lens offers an ultra-slim, lightweight design that helps photographers avoid overwhelming their subjects with a large lens and to remain discreet in sensitive shooting situations without compromising performance. The “pancake-style” lens boasts an aperture of f/2.8 making it an ideal lens for capturing portrait stills or stunning video. The lens is under an inch thick when attached, making it easy to carry and fit conveniently into a purse or pocket.

The EOS Rebel T4i is also compatible with Canon’s previously introduced GP-E2 GPS Receiver that can be mounted to the camera’s accessory shoe. The GPS unit was created to serve outdoor photographers; it records shooting locations including latitude, longitude and altitude, as well as camera direction. A Logging function can tell how far a photographer has traveled as well.

Zanimljivo. Naravno, OPET me nervira uporno drkeljanje istog senzora, ali je barem dosta drugih stvari unapređeno. Najbolji AF u klasi (i dalje sam sumnjičav pre video-AF-u, ali videćemo), brži rafal, stereo mikrofon, poboljšani sistem interne obrade, pojačana osetljivost senzora... nije loše!

E sad, na delu je opet redefinicija klasa... kako ih ne mrzi više...(?)  :-\

Početak prodaje se očekuje za kraj Juna, a predviđene su sledeće cene:

-samo telo = 849$
-kit 18-55 IS II = 949$
-video kit sa novim 18-135 STM = 1199$

Cene deluju napucano, ali pošto znamo da su identične kao i kada se pojavio 600D, znači da će u relativno kratkom roku otići naniže, što je sasvim ok, posebno s obzirom da je 650D podignut otprilike na nivo u kojem je gravitirao (i još uvek gravitira) 60D, sa izostankom statusnog displeja.

Zamalo da zaboravim ključnu stvar: fazni fokus direktno pomoću hibridnog glavnog senzora, sa dedicated AF tačkama.
Tek će se sad videti koliko je Sony SLT retardiran dizajn. :D

Dpreview je predstavio Sample Gallery:

http://www.dpreview.com/galleries/reviewsamples/albums/canon-eos-650d-rebel-t4i-preview-samples

Vlasnik sam Canona 550D i cini mi se da je ISO na 650D podignut za 2 stope (pogledajte poslednje slike iz studija) ISO3200=ISO12800

Sta mislite ?

Takodje, ako neko nadje test videa sa AF, neka ga postavi cim prije (ima nekoliko fejk na YT).

@ mickland

To što govoriš je teoretski nemoguće ako se koristi Bayer senzor kakvoga danas poznajemo, moguće doduše u in-camera JPEG-u ali nauštrb detalja.

Ne verujem da je napravljen bilo kakav napredak u ISO performansama, ali znam da su napravili neku funkciju koja (u JPEG-u, kako je Bare i pomenuo) rokne 4 snimka, pa onda od ta 4 napravi jedan sa dosta manje šuma. O upotrebljivosti ne znam ništa, moraćemo da sačekamo neke konkretne primere.

@ cronnin

Hvala na trudu.

Ovako poredjani kropovi daju jasnije poredjenje.  .
ISO 800 i 1600 sigurno bolje izgledaju nego na 550D, ali vec 3200 pa nadalje nisu drasticno bolji.

Slazem se sa STORM-om da treba sacekati jos primera kao i da je poboljsanje softwarske prirode (zbog brzeg procesora).

Takodje, priznajem da moze biti da nisam objektivan jer sam nameracio da ga kupim kad izadje, pa trazim opravdanje. Sto je babi milo to joj se i snilo  ;D

Citat
DIGIC 5 is now featured on Canon compact cameras like PowerShot SX40 HS to achieve a capture rate of 10.3 frames per second at full resolution in High-Speed Burst HQ, Full HD 1080p Videos and Intelligent Image Stabilization. The new DIGIC 5 processor is 6 times faster and creates 75 percent less noise than the DIGIC 4 processor.[7]Designed to achieve new and advanced levels of image quality, DIGIC 5 analyses four times more image information to create each pixel, recording more detail and colour from a scene than ever before. Processing speed is also six times faster compared to the previous processor, efficiently managing the increase in scene information and simultaneously reducing the appearance of image noise by up to 75%.

DIGIC 5 Is used in the Canon EOS 650D/Rebel T4i/Kiss X6 (announced June 8, 2012 and available later that month).

Ako je pola od ovog tacno, onda treba ocekivati bolju ISO kontrolu.
