Noua camera 4K de la Canon - XC10

Noua camera 4K de la Canon XC 10 a fost prezentata in China, inainte de NAB 2015 Las Vegas.
Specificatiile tehnice sunt:
  • Senzor CMOS 1″
  • Wi-Fi
  • Viewfinder extern
  • Lentila fixa Canon 10X zoom optic 8.9-89mm (35mm Equi. 24-240mm) f/2.8-5.6.
  • 58mm filter
  • Filmare evident 4K
In urma acestor specificatii pot sa va spun ca un senzor de  1″ este suficient de capabil, dar ma dezamageste diafragma maxima a lentilei cel putin pentru telefoto - zoom maxim  (f/5.6). Logica in acest caz este compromisul calitate / pret.

P.S. Dupa cum se vede la prezentare a participat si Jackie Chan :)


Update 9 aprilie 2015:
Video hand-on cu aceasta nou camera video.




Pretul este destul de marisor 2499$ :(

Anuntul oficial:
Unleashing 4K recording for enthusiasts
Boasting outstanding market leading image quality, traditionally associated with larger cameras, as well as the flexibility and ease of use of traditional compact camcorders, the XC10 delivers consistently breath-taking results. Its advanced imaging engine – a powerful combination of a specially developed 1” CMOS sensor and Canon’s new DIGIC DV5 image processor – gives both budding filmmakers or experienced pros the blistering speed and quality they demand to capture 4K video, at a wide range of variable bit rates.
Able to fit seamlessly into workflows, or productions with existing Cinema EOS cameras, the XC10 can record UHDTV standard (3840 x 2160) 4K footage to an internal CFast 2.0™¹ card at up to 305Mbps, or Full HD (1920 x 1080) footage to an SD card at up to 50Mbps, with pro-standard 4:2:2 colour sampling for high resolution performance.
The XC10 delivers rich colour, synonymous with Cinema EOS cameras, with a high ISO of up to 20,000, ensuring excellent results in low light conditions, and a 12-stop Wide Dynamic Range, providing vivid detail in both highlights and shadows.
Shooters have the freedom to capture a diverse range of scenes in professional 4K quality using a specially developed 10x optical zoom lens, complete with Canon’s class-leading image stabilisation technology. With a versatile 27.3-273mm focal range (35mm equivalent, in video mode) videographers can easily switch between capturing sweeping scenes, to intimate close ups with a single lens. Pros and enthusiasts alike can change between movie recording and still image shooting, capturing high quality 12.0 MP images, or extracting 8.29 MP stills from 4K video footage.

Brevet de inventie pentru o noua lentila Canon 24-600mm f/2-3 - senzor de 1″

Canon Lens Patent Shows 24-600mm f/2-3 Optics for 1″ Sensor
Firma Canon a aplicat pentru un nou brevet de inventie (patent) pentru aparatele foto point&shoot. De aceasta data combinatia este demna de bagat in seama:
Ca sa va faceti o ideie ar trebui sa fie asemanator cu  Sony RX10.
Sony RX10

Daca acest "Moby Dick" in lumea foto va aparea pe piata trebuie sa va asteptati si la un pret serios - banuiesc 900 sau 999,99$ :)
Din pacate calitatea vine la un pret pe masura :(

P.S.: O sa va intrebati de ce sa va bateti capul cu asa ceva atat timp cat sunt pe piata aparate DSLR si mirrorless? Am si raspunsul:
  • letilele similare pentru DSLR in aceasta combinatie (lungime focala + diafragma maxima) sunt extrem de scumpe - o lentila 70-200mm F/2.8 costa cel putin 4000 de lei iar peste 200mm avem probleme serioase in legatura cu pretul;
  • echipamentul este foarte greu - o lentila 70-200 f/2.8 stabilizata cantareste aproximativ 1,5 kg, iar peste 200 mm lucrurile o iau razna;
  • pana la urma trebuie sa nu uitam ca un aparat de acest gen inseamna un compromis intre pret si calitate. Daca acest compromis este mic atunci este demn de bagat in seama.

Noile lentile Sony pentru Full Frame

Zeiss 35mm F1.4 ZA lens
Surprize placute legate de noi lentile si convertoare in tabara Sony: 3 noi lentile prime (Sony FE 28mm F/2, Zeiss Distagon FE 35mm F/1.4 ZA, Sony FE 90mm F2.8 Macro G OSS) si un nou zoom (24-240mm F3.5-6.3 FE OSS). Pentru lentila zoom este postat si un review de catre BHphotovideo la adresa http://www.bhphotovideo.com/explora/photography/hands-review/hands-review-sony-fe-24-240mm-f35-63-oss-super-zoom-lens
Acest lucru demonstreaza seriozitatea implicarii firmei in domeniul foto.
Sony 24-240mm F3.5-6.3 FE OSSDupa cum spuneam intr-un articol mai vechi http://aperturemag.blogspot.ro/2014/11/the-next-big-thing-in-photography-Sony.html firma Sony este pe cai mari si doreste sa recupereze distanta dintre ei si firmele rivale Canon si Nikon care detin majoritatea pietei in zona DSLR.
Lentilele Zeiss au AF (auto-focus) pe montura Sony iar pentru restul lumii (Canon, Nikon) doar manual focus :)
