  1. - Speilrefleks har fortsatt overtaket på følgefokus. Vi får se om det fortsatt stemmer når NX1 blir tilgjengelig, men det vill forbause meg om Samsung har fått til noe som er konkurransedyktig med high end speilrefleks. Nøyaktighet til kontrastbasert fokusering er imidlertid bedre og man kan også i stor grad glemme mikro fokus justering og fokusshift med lyssterk optikk.

    Det blir spennende å se hvordan AF til NX1 yter, men det vil overraske stort om den klarer å å holde følge med 7D mk2/1DX/D4s.

    Foreløpig sparsomt med info om NX1 sin AF, men den kan jo overrsake positivt.

    Phase detect går ned til EV -2, og contrast detect helt ned til EV -4, og til sammen har punktene en dekningsgard på ca.90% (betydelig mer enn 7d Mk2). I tillegg en AF illuminator som har en rekkevidde på 15m. Regner med NX1 har en form for Auto Subject tracking også. Så alt ligger til rette for et kompetent AF-system. Desverre går NX1 ned til 12bit RAW under maks fps. Neppe så mye praktisk forskjell over iso 400, men noen ganger er det faktisk sol og gode lysforhold og iso 100/200 benyttes.

    Men hva med AFMA? AF f8? Tilpassningsmuligheter?

     

     

    Vi vet at 7D mk2 har AFMA, AF f8 med 5 punkter, har 6 ulike Case-instillinger som hver er tilpasset ulike situasjoner med mulighet for manuelle justeringer av følsomhet, flicker detection, EV -3, 4 programerbare knapper. Det er også mulig å stille hvordan AF-punktene flytter seg fra horisontal til vertikal posisjon av kameraet.

     

    Det blir spennende å se tester av både NX1 og 7D mk2, men jeg tror 7D mk2 sitt AF-system kommer til å yte bedre og ha langt flere tilpassningsmuligheter.

  2.  

    Kan hende at salget på mkII blir såpass labert at Canon kjapt sender en oppgradert utgave på markedet med wifi/touch-skjerm, jeg håper ihvertfall det :)

     

    Jeg tror Canon sitter med begge beina i en felle: De er veldig redde for at salget av en modell skal kannibalisere en annen, her at 7Dii skal kannibalisere 1DX.

    Det kan også tenkes at de føler et sterkt behov for å spare noe til neste oppgradering.

     

    1Dx og 7D mk2 er så forskjellig i pris, og FF mot crop, og hadde Canon vært bekymret for at 7Dmk2 skal ta salg fra 1Dx så hadde Canon kneblet AF-systemet.

    Jeg tror faktisk det er motsatt. Ved å toppe AF-systemet i 7Dmk2 og til og med gjøre det bedre på et par punkter enn 1Dx så kan det bli et attraktivt backup kamera for 1DX-eiere. Samtidig som det appelerer til alle som ikke har råd til 1Dx, ved at man får nesten samme hastighet, så og si samme AF-system med de samme menyene som storebror.

  3. Det høres veldig rart ut om Samsung skal ha laget tidenes råeste seriebildekamera uten å gi det en skikkelig buffer.

    Bufferen er 30+ ryktes det, og det holder til 2 sek. Kvaliteten senkes desverre fra 14bit til 12bit i Continuous mode, men på et tidspunkt må jo også Samsung gå tom for buffer. 15*28 gir pene 420mb/s, men hvor mye reduseres størrelsen ved å gå ned i 12bit?

  4. matt granger har testet mkII.

     

    ISO 51200 ser ikke så ille ut, ser ut som iso-støy problemer er en stor oppgradering fra mkI.

    Jpg nedsamplet fra 20mb til 2mb eller noe er ikke den beste indikatoren på høy iso-ytelse. Vi får vente til det foreligger testbilder i raw. Det vil overraske stort om isoytelsen blir særlig mye mer enn 2/3 - 1 stop bedre enn 7D.

  5. Et veldig bra kamera. Fint å se at Samsung topper med alt de har i et speilløst, de har jo ingen andre toppmodeller å beskytte som f.eks CaNikon og Sony.

    15 fps er rått, selv om det sies at det bare er 12 bit raw, men det gjenstår å se hvor effektiv AF er. Hjelper ikke med rask fps dersom fokus ikke sitter.

    Har NX1 en eller annen form for tracking, face-rec/farge e.l.?

    • Additional Features

    20.2 Megapixel CMOS (APS-C) sensor and ISO 100–16000
    The EOS 7D Mark II has a newly designed 20.2 Megapixel sensor that delivers high-resolution image files with stunning detail and impressive clarity. Optimized for low-light shooting, the EOS 7D Mark II’s sensor captures images at up to ISO 16000 (expandable to H1: 25600, H2: 51200) with remarkably low noise, thanks to its improved, higher sensitivity design. Phenomenal for stills, the EOS 7D Mark II’s sensor is equally up to the task for movies, delivering Full HD capture even at rates of up to 60p.

    Dual DIGIC 6 Image Processors

    The EOS 7D Mark II’s sensor works seamlessly with its Dual DIGIC 6 Image Processors for advanced image processing across the board. These image processors help the EOS 7D Mark II capture up to 1090 JPEG, 31 RAW, and 19 RAW + JPEG shots in a single burst for amazing action photography. Further, they enable the camera’s powerful image processing on-the-fly: lens aberration, variances in peripheral illumination and image distortion can all be corrected in real time thanks to the EOS 7D Mark II’s Dual DIGIC 6 Image Processors.

    High speed continuous shooting up to 10.0 fps allows you to capture fast action
    With a new, rugged shutter designed for 200,000 cycles, the EOS 7D Mark II can shoot up to 10 frames per second to capture all the action. With super quick AF and exposure systems complementing the shutter’s 55 msec shutter release time lag, the EOS 7D Mark II is tailored to meet and even exceed the speed of the action. Refined mechanics like a newly designed, more efficient shutter-drive motor and a vibration dampened mirror drive mean impressive performance for high caliber image quality, fast.

    Sophisticated Mirror Control System
    The EOS 7D Mark II camera employs an advanced mirror vibration control technology that enables the camera to support its speedy, continuous shooting capabilities while ensuring great image quality. The system uses a motor to help reduce the vibrations caused by high-speed shooting. By reducing the vibrations, the camera can achieve accurate and precise autofocus to provide steady and clear action shots at up to 10.0 frames per second.

    65-point* all cross-type AF system for high-performance, accurate subject tracking with EV -3 sensitivity (center point) for focusing in extreme low-light conditions
    An EOS first, the EOS 7D Mark II features 65 all cross-type AF points* for high precision AF at remarkable speed. Cross-type AF points ensure stable AF that is not influenced by the subject’s shape or color. On the EOS 7D Mark II, the AF points are spread over a wide area of the frame, enabling faster AF, wherever the subject lies. With a central dual cross-type AF point of f/2.8, AF is enhanced with lenses faster than f/2.8. And thanks to this new system, AF is possible even in dim lighting as low as EV-3.

    Canon’s innovative Dual Pixel CMOS AF enables you to shoot video like a camcorder with smooth, fast, and accurate autofocus and lets you enjoy instant and precise autofocus even when shooting stills
    The EOS 7D Mark II features Canon’s revolutionary Dual Pixel CMOS AF, a milestone in AF speed and accuracy that unlocks the potential of Live View shooting. This advanced technology has truly changed what is possible with a DSLR camera. Dual Pixel CMOS AF involves a sophisticated rethinking of the CMOS sensor. Traditionally, image sensors have one photodiode per pixel for recording, but the CMOS sensor on the EOS 7D Mark II has two photodiodes per pixel, 40 million in total, enabling each pixel on the sensor to both perform phase-difference detection autofocus and capture light. With phase-difference detection AF, autofocus is achieved quickly and easily on the camera. This unique AF system enables autofocus on approximately 80% of the image plane, vertically and horizontally, and helps ensure virtually no loss in image quality.

    Stunning Full HD video with custom Movie Servo AF (speed and sensitivity) for continuous focus tracking of moving subjects,
    multiple frame rates including Full HD recording at 60p in MOV and MP4 formats and uncompressed HDMI out
    While offering performance improvements across the board for still photography, the EOS 7D Mark II is also an incredibly capable HD movie camera. Taking advantage of its Dual Pixel CMOS AF capabilities, the EOS 7D Mark II has customizable Movie Servo AF options: not only can AF location be defined, AF speed and tracking intervals can be specified too, for fluid, smooth focus transitions. The EOS 7D Mark II delivers refined and detailed image quality with Full HD 60P recording at ISO values up to 16000, has an HDMI output and records to both SD and CF cards for versatility and security during important shoots.

    Intelligent Viewfinder II provides approximately 100% field of view for shooting ease
    The EOS 7D Mark II’s Intelligent Viewfinder II makes it easy to both shoot, change and confirm camera settings and shooting modes all without looking away from the viewfinder. Displaying approximately 100% of the composition, the viewfinder can show settings like shooting mode, exposure level, white balance, drive mode, AF operation, metering mode, recording format, even an electronic level and more. All of this information can be displayed by or superimposed easily over the image for review while shooting, and multiple views are customizable through the EOS 7D Mark II’s simple user interface.

    Improved custom controls and built-in intervalometer and bulb timer for expanded creativity
    An EOS first, the EOS 7D Mark II offers time-lapse fixed-point shooting and long exposures without the need for a remote control. The EOS 7D Mark II’s interval timer takes from 1 to 99 shots at preselected intervals, ideal for shooting flowers as they bloom or clouds drifting through the sky. Its built-in bulb timer keeps the shutter open for a designated amount of time, perfect for night photography, or to capture the flow of traffic on a street corner.

    Magnesium alloy body with shutter durability up to 200,000 cycles and enhanced dust and weather resistance
    The EOS 7D Mark II is constructed of the highest quality materials, and to exacting standards that ensure unfettered performance at all times. For example, the shutter can shoot at speeds up to 1/8000 sec. for up to 200,000 cycles, the chassis is built of lightweight and rigid magnesium, and the camera’s seals are built to resist water and dust. This combination makes the EOS 7D Mark II ready for almost anything.

    EOS Scene Detection System features a new 150,000-pixel RGB+IR Metering Sensor for improved precision
    The EOS 7D Mark II has an amazing iSA Intelligent Subject Analysis system that employs an independent RGB light sensor with approximately 150,000-pixel resolution. This sensor enables Canon’s intelligent Tracking and Recognition system (iTR AF) that detects and tracks subjects, automatically switching the AF point to optimize tracking. With new tracking algorithms tailored to recognize faces and colors, this system serves as a brilliant foundation to the EOS 7D Mark II’s AF system.

    Anti-flicker shooting
    The EOS 7D Mark II features a new flicker detection system that not only alerts the user in the viewfinder, but with the camera’s Anti-Flicker Shooting function can compensate for flickering light sources, taking shots only at peak light volume. This feature is useful for minimizing disparities in color and exposure, especially during continuous shooting in sub-optimal lighting situations.

  7. Det absolutt mest spennende med 7D mk2 er AF-systemet:

    - 65 punkter, alle cross-type (1DX har 61, og ikke alle er cross-type)

    - iTR (antageligvis samme som 1DX)

    - RGB + IR 150.000-pixel metering (1DX har RGB 100.000 pixel-metering).

    - DPAF

     

    Dette har potensialet til å bli helt på høyde med 1DX, til og med enda bedre.

    I tillegg herlige 10 fps, og jeg håper virkelig Canon har gitt 7D mk2 en rikelig buffer.

     

    Det blir spennende å følge med mandag/tirsdag for mer detaljer ang. type og oppløsning på skjerm, -2EV eller -3EV, sync-hastighet blits, pris, tilgjengelighet, line skipping eller pixel binning video, DR, høy og lav iso-ytelse.

  8.  

    Synes at det er bra slapt med 1/4000 som min lukker hastighet. Burde være 1/8000 på et kamera som blir omtalt som et action kamera.

    Hva slags action er det du fotograferer som trenger 1/8000?

     

    Som Kenneth allerede har nevnt skjer det støtt og stadig når man tar bilder av fulger mot solen og himmelen. Så litt slapt av Nikon å ikke ta det med når det omtales som et action-kamera.

    Interessant med RGB + IR photometry sensor, men hvilke fordeler gir det?


  10.  

    "20 is the new 18"

    Magic Lantern har jo gjort underverker med 5Dmk3 som gjør det mulig å løfte skygger omtrent på nivå med Sony. Det er signalbehandlingen Canon sliter med, og det er jo lov å håpe Canon har sett på det ML har gjort og klarer å gjøre noe lignende med 7D mk2. Kanskje dual digic 6 kan brukes til dual ISO? I så fall kan det gi betydelig økt rom for etterbehandling.

    Uansett så er det viktigste for meg en rask og pålitelig AF. Min trofaste 40D er overmoden for en oppgradering.

    "dual ISO" er en spenstig work-around for høy støy ved lav ISO. Det er ikke en fullgod erstatning for sensor/elektronikk som har lav støy i utgangspunktet (som konkurentene nå har).

     

    -k

     

    Helt rett, men bedre enn ingenting. Tviler på at en refresh av 20,2mp-sensoren har spesielt bedre DR og mindre lav iso støy enn 70D har i dag, og da kan "dual iso" være en nødløsning inntil Canon kommer på nivå med Exmor.

  11.  

    ...Spesielt nyttig kan berøringssensitiv skjerm også være med stillesittende motiver.

    Det tror jeg også, men en evt "7Dmk2" vil vel være spesialisert for motiver i bevegelse? Dvs at det er mer trolig at Canon vil fase inn slik funksjonalitet i f.eks 6D?

     

    -k

     

    Helt enig i det, fart er nok spesialiteten. Men noen ganger sitter fugler i ro, og da er det praktisk å kunne sette fokus med touch-skjerm. Canon har jo tendens til å holde igjen funksjonalitet for å beskytte andre modeller.

  12. Oppdatering av spec-list

    • We’re not 100% sure about GPS, we think the camera may actually have it.
    • We mentioned radio triggering with the popup flash, but that may have been a mistake.
    • “Fine Detail CMOS Sensor” is standard Canon language for Canon sensors.
    • The camera has iTR (metering sensor-assisted servo tracking) just like the EOS-1D X
    • The camera should be compatible with f/8 lenses at the center, and maybe more points

    Det er gode sjanser det blir en helt ny 20,2mpx-sensor, og ikke den samme som er i 70D. Som forventet AF f/8 i senter, og kanskje flere punkter også.
