Tuossa ei kyllä ole oikeastaan paljoakaan hyvää. Sen osoitti jo 50D ja lisämegapikkelssit olisi askel väärään suuntaan. Toivon, että ei tule noilla specseillä. 1.3x ja 18MP, olisi järkevämpi pikselitiheyden puolesta.

Pikselikisa näyttää ainakin Canonin osalta jatkuvan.Jos kerrottu pitää paikkansa niin ei hyvä.

18MP. Siitähän tulee sraw1 tilassa 9MP! Yhdellä asetusmuutoksella huonosta kamerasta hyvä.
Jos vielä isommat pikselit kiinnostaa, niin sraw2 tilassa tarjolla olisi 4 1/2 MP kenno!

Joo kyllä se 18MP on varmistunut. Canonin (tai kuka lie kennon valmistanut) on pitänyt tehdä jonkinlainen harppaus kennotekniikassa, jotta matalakontrastisten yksityiskohtien erottelu ei ole aiempiin malleihin nähden huonontunut.

Olikos jollain tietoa siitä, että onko siihen jokin tekninen syy ettei tämä tarkenna f/8 max aukolla, vai onko tuo ominaisuus jätetty pois tarkoituksella? Jotkut tipuräpsijät jäänevät tuota ominaisuutta kaipaamaan.

Miksi matalakontrastisten yksityiskohtien erottelu huononee samankokoisella kennolla ja samalla optiikalla? Esitätkö että 7D:llä otettu kuva tulostettuna A3 kokoon on huonompi/ vähemmän kontrastikas kuin esim. 40D:llä?

Ei pelkästään kontrastista vaan pikseli- ja sensorikoon merkityksestä:

The factor that limits the low ISO performance of DSLR's turns out to be the limited dynamic range of the ISO amplifier and ADC components downstream from the sensor, and not the sensor itself
http://theory.uchicago.edu/~ejm/pix/20d ... #pixelsize

Sitten siitä automaattikäännetystä pressitiedotteesta:
higher photoelectric conversion efficiency of the new photodiode. In improving the pixel sensitivity at the same time, the transistors within a pixel was modified to achieve a higher S / N (signal to noise) ratio.

Hyvä jos canon on onnistunut parantamaan noita em. komponentteja 7D mallissaan. Jos veikata pitää niin ero 50D:hen (jossa jo on gapless microlenses eli lisää valoa kuvaan ei ole luvassa) jää silti mitättömäksi kuvanlaadun osalta. Mutta muita parannuksia sitten onkin vaikka muille jakaa.

Nipsu kirjoitti:Miksi

No kattos vaikka tämä:
http://www.imaging-resource.com/PRODS/T1I/T1IA.HTM

Kelaa about 3/4 alaspäin, kohtaan Canon T1i Beta vs XSi at ISO 1,600:

It's clear from the top two images that the Canon T1i has made a few leaps in terms of detail and noise suppression, but the cost is also evident, again in the red leaf fabric. The image from the XSi is much closer to the true look of the fabric than you get from the Canon T1i at left. This result is partly due to the higher resolution, which means that smaller pixels are producing the overall image. With less light on each pixel, the processor has more noise to deal with, which results in a loss of detail in low-contrast areas. This is actually a worse performance than even the Nikon D300 turned in on this fabric. I should also note, however, that this quality degradation doesn't start until ISO 1,600. From ISO 800 on down this fabric swatch looks quite good.

Sama testi setup, saman kokoinen kenno, uudempi kamera, enemmän pikkelssejä, huonompi matalakontrastisten yksityiskohtien erottelukyky . "XSi" eli 450D pärjää tuossa suhteessa 12,2 miljuunalla pikkelssillä paremmin kuin 500D tai 50D 15.1:llä mpikkelssillä.

Muutenhan tuo 7D on specsien puolesta erittäin hyvä päivitys 10-sarjaan, mutta kyllä tuota kuvanlaadun kehittymistä on syytä epäillä ennen kuin asiasta on mitään todisteita. Sitäpaitsi, jos kuvanlaatu (varsinkin S/N) olisi 50D:n tasolla, niin helevettiäkö menivät entisestään vielä pikkelssejä lisäämään, jos ei niistä ole mitään hyötyä? Tiedostokoko vaan kasvaa.

Niin siis eiköstä ne olleet klasit jotka pissivät resoissa eikä itse kenno? Miettikäähän miten pikkurillin kokoiselle G10:n kennoa on saatu ahdettua läjä pikkelssejä ja miten tuosta pikkelssimoskasta saadaan korkearesoluutioinen kuva ulos joka on lähentelee järkkärimaailman peruskaluston tasoa.

Ja käsitääkseni se laadukas AA filtsu on jo kaliimpi osa kuin itse kenno jos en ole vääriä huhuja kuunnellut.

Mikäs sen parempi tehtaille kuin lähteä myymään uusia klaseja kaikille.

CANON U.S.A. REDEFINES MID-RANGE DSLR CATEGORY WITH THE NEW EOS 7D DIGITAL SLR CAMERA
The EOS 7D Features Fast Eight fps Continuous Shooting, Class-Leading 18-Megapixel Resolution and Full HD Video Recording with Variable Frame Rates and Manual Exposure Control

Lake Success, N.Y., September 1, 2009 – Canon U.S.A., Inc., a leader in digital imaging, today introduced a revolutionary camera that redefines the highly competitive mid-range DSLR product category: the Canon EOS 7D Digital SLR camera. Professional photographers and advanced amateurs have been demanding higher performance and more diverse functions in their cameras, and Canon has answered – with the new EOS 7D. Far more than a slight improvement from a previous model, the EOS 7D DSLR is a brand new product that stands on its own with new features never before seen in any Canon camera. Whether it's shooting at eight frames per second (fps), focusing with the new Zone AF mode or recording 24p Full HD video, the EOS 7D DSLR camera satisfies the most rigorous professional requirements with durability, flexibility, high-resolution images and customizable controls. With its unprecedented out-of-the-box performance and high-end feature set, the EOS 7D is poised as the ultimate step-up camera for serious photographers or a second camera for professionals in the field.

The EOS 7D boasts significant EOS advancements including a completely new 19-point Autofocus system, a new Canon iFCL Metering System (Intelligent Focus, Color, Luminance) and a new Intelligent Viewfinder. An 18-megapixel Canon CMOS sensor and Dual DIGIC 4 Imaging Processors fuel the EOS 7D's 14-bit A/D data conversion and its ability to freeze fast motion in high-resolution with eight fps continuous shooting up to 126 Large JPEGS using a UDMA CF card, positioning this camera for the studio as well as the sideline. The EOS 7D captures beautiful low-light images with or without a flash, at occasions such as a dance recital or wedding reception, thanks to a wide range of ISO speed settings from 100-6400 (expandable to 12,800). In addition to its new still capture capabilities, the EOS 7D features Full HD video capture at 1920 x 1080 resolution with selectable frame rates of 24p, 25p or 30p. Native 24p recording helps videographers achieve a more cinema-style look for their footage without the need for post-processing.

"The EOS 7D represents a completely new chapter in digital photography and Canon product development. This camera stands alone as the most functional and innovative DSLR Canon has released to-date, bringing together all of the best professional features offered, along with numerous user requests at a price-point everyone can appreciate," stated Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.S.A.

The Evolution of Vision, the EOS 7D's New Autofocus System
The Canon EOS 7D boasts the most advanced AF system ever seen in an EOS SLR. The completely re-designed system includes a new multi-axis cross-type 19-point AF grid, where the focusing points are evenly spread out across the image plane and clearly displayed through Canon's new Intelligent Viewfinder. All 19 points are f/5.6-sensitive for both horizontal and vertical cross-type focusing, while the center AF point adds high-precision diagonal cross-type sensitivity for f/2.8 and larger aperture lenses. The Canon EOS 7D Digital SLR camera is the first EOS SLR to feature 19 cross-type focusing points that remain fully functional with maximum apertures as small as f/5.6, which brings the performance of the AF system to unprecedented levels for assignments as varied as fast-moving sports action or low-light wedding ceremonies.

The Canon EOS 7D's AF system allows numerous AF area selection modes never seen before in an EOS SLR camera. New modes include:

# Spot AF mode reduces the size of a single AF point to focus on small subjects like an animal in a cage.
# AF Point Expansion mode uses a cluster of AF points adjacent to the selected AF point to automatically assist focusing on moving subjects, such as an athlete on the run.
# Zone AF divides the 19 AF points into five selectable focusing zones and makes it easier to achieve focus with subjects that are difficult to track with Single Point AF or AF point expansion, such as birds in flight.

Additional AF improvements include a revised Automatic AF point selection sequence that allows a user to pick any one of the 19 AF points as a starting point for tracking moving subjects in AI Servo mode. (Previous EOS models required the subject to first be acquired by the center focusing point.) If the subject moves away, the camera will continue to track the movement with the remaining points and display the active focusing point in the viewfinder. Also, a time-saving feature is AF Point Switching, which allows photographers to select and register one AF point for horizontal compositions and a second AF point for vertical shooting, ideal for studio and portrait photographers.

To complement the new AF system, the exposure metering system for the EOS 7D has been completely re-designed to take color information into account, another first for an EOS system. Canon's iFCL metering includes a 63-zone dual-layer metering sensor that reads both illumination and color for consistent results in all lighting conditions, keeping exposure levels stable from shot to shot, even as the light source changes.

Canon's new Intelligent Viewfinder uses a liquid crystal overlay to provide clear and precise displays of focusing points and zones, on-demand grid lines and a spot metering circle. The LCD overlay can also be illuminated in extreme low-light situations or turned off completely. The EOS 7D camera's viewfinder includes a large all-glass pentaprism with an antireflective coating to maximize clarity and provide a brighter display. The EOS 7D's Intelligent Viewfinder features 1.0x magnification with 100 percent coverage for accurate composition and checking of detail.

EOS HD Movie: Empowering the World of Videography
Canon has blazed new trails in HD video capture with the 5D Mark II. Now, the EOS 7D takes DSLR video to new heights with Full HD capture featuring fully manual exposure control, and selectable cinematic frame rates for both NTSC (National Television System Committee) and PAL (Phase Altering Line) standards. Compatible with more than 60 Canon EF and EF-S lenses, the EOS 7D lets videographers take full advantage of the camera's large CMOS sensor to achieve the dramatic frame composition they desire. At the heart of the EOS 7D are two key proprietary Canon technologies, Dual DIGIC 4 Imaging Processors and a large APS-C-sized CMOS sensor, helping to render stunning color reproduction, amazing depth of field and fine detail, even in low-light conditions. The Canon EOS 7D allows for three video recording modes – Full HD and HD in a 16:9 aspect ratio and Standard Definition (SD) in a 4:3 aspect ratio, all at selectable frame rates. The EOS 7D Digital SLR camera will record Full HD at 1920 x 1080 pixels in selectable frame rates of 24p (23.976), 25p, or 30p (29.97); 720p HD recording at 50p or 60p (59.94) and SD video at frame rates of 50p or 60p (59.94). The EOS 7D features a new dedicated button to initiate live view for both video and still shooting. Once engaged, the same dedicated button will start and stop video recording. Like the EOS 5D Mark II, the Canon EOS 7D Digital SLR camera provides users with the capability to use an external stereo microphone for professional audio effects or a built-in monaural microphone for convenience.

The Features You Asked For
A helpful new tool for architectural and landscape photography where angles and perspective are critical is Canon's new built-in Dual Axis Electronic Level, featuring an artificial horizon over the image on the rear LCD screen in Live View or in the viewfinder using illuminated AF points for easy leveling while shooting. The dual axis electronic level shows both horizontal roll and vertical pitch, making it easy to identify when the camera is in a fixed level shooting position and ready to take the shot.

The EOS 7D's pop-up flash features a built-in Integrated Speedlite Transmitter for control of multiple off-camera EOS Speedlites without the need for an external transmitter. This built-in wireless option is a compact and economical solution for studio and wedding photography with multiple flash set-ups.

A new Intelligent Macro Tracking function helps reduce blur during macro shooting by recognizing when a macro lens is attached and automatically adjusting the AI Servo sampling frequency. This AI Servo adjustment accounts for camera movement forward and back, a typical occurrence when moving in close for a macro shot as photographers rock back and forth, or a flower blows in the wind.

Once in your hands, you can immediately feel the ergonomic improvements of the Canon EOS 7D camera, starting with a new super-fluid body design with continuous curves outlining the top of the camera and a revised grip that fits better in a user's hand. The camera has a new Quick Control Button, which opens an easy-to-navigate menu on the camera's LCD screen. From this menu, users can adjust all camera settings including AF modes as well as set custom button functions, an insightful new feature that can easily customize each button's function to the photographer's preference. Another new feature is the RAW/JPEG toggle button providing quick dual-format shooting, allowing photographers to quickly add large JPEG or RAW file formats to their already selected shooting mode at the touch of a button.

The Canon EOS 7D camera also features a new large, clear 3.0-inch solid structure Clear View II LCD screen with 920,000 dot/VGA resolution for enhanced clarity and color when viewing images. The camera's nine internal seals enhance weather resistance, and its 150,000-cycle shutter durability positions the EOS 7D as a "workhorse" for professionals in any photography discipline.

New Wireless Connectivity
Canon is announcing the availability of the new WFT-E5A wireless file transmitter (WFT) exclusively for the EOS 7D Digital SLR camera. The WFT-E5A wireless transmitter offers professional photographers a wide range of digital connectivity options including IEEE802.11a/b/g and Ethernet, ideal for commercial and studio work. The WFT-E5A wireless file transmitter opens the door to new possibilities in remote and Geotagged shooting applications.

7D.ssä osa tekstuureista näkyy, kun D300:ssa ei näy. Punaisen käsittely on jotenkin hmm - persoonallista 7D:ssä?

Lukuunottamatta värikäsittelyn erilaisuutta niin 7D on hyvin lähellä 5D.tä kun pitää hanskata noi tekstuurit.
