풀프레임 DSLR 카메라 탐방
Full Frame DSLR Cameras Review

최근 소니의 알파900이 세계최고 2460만화소의 풀프레임을 내놓으면서 DSLR 매니어들의 관심을 증폭시키고 있는데 얼마전까지 캐논의 괴물 EOS 5D mark-2 는 과연 소니의 알파900보다 뒤지는 성능인가 알아 본다.

성능을 보는 차원에서는 브랜드 이미지나 그 회사의 전문성은 배제한다.
소니는 전자메이커이고 캐논은 카메라메이커임 으로 브랜드를 비교해선 안되기 때문이다.

    풀프레임 DSLR 카메라 탐방
    Full Frame DSLR Cameras Review

    최근 소니의 알파900이 세계최고 2460만화소의 풀프레임을 내놓으면서 DSLR 매니어들의 관심을 증폭시키고 있는데 얼마전까지 캐논의 괴물 EOS 5D mark-2 는 과연 소니의 알파900보다 뒤지는 성능인가 알아 본다.

    소니는 전자메이커이고 캐논은 카메라메이커임 으로 브랜드를 비교해선 안되기 때문이다.


소니 알파900  DSLR 카메라 
전자 브랜드에서 만든 최고급 DSLR  카메라

 소니 알파 DSLR 소개
세계최고 화소의 풀프레임


 
소니의 풀프레임 DSLR A900이 세상에나온지 한달좀 됬군요.
 
이제 쉽게 알파900을 말하지만 A900에 대해 소니가 심혈을 기울린 작품이라는것이 하나둘 사용자들로부터 나오기 시작한답니다.
2006년 코니카미놀타를 인수하고 보급형 A100을 시작으로 중급형 A700, 그리고 올초 보급형 A200, A300, A350을,만든 노하우를 바탕으로
전문가형 풀프레임 A900을 완성시킨것은 이미계산된 행보였을것이다.
 
DSLR시장의 신참이지만 세계적 전자메이커답게 새로운 모델들이 출시될때마다 기존 DSLR 시장관계자들을 깜짝놀라게 하는 사양과 마케팅으로 쇼크를 주어왔는데 이번에 도 출시된 풀프레임 A900은 2007년초부터 약간씩 사양을 흘리며 관심을 계속 모으면서 유저들의 관심을 유도하고 있었지요.
dpreview엔 A900이 판매되기 한달전쯤부터  한달동안 충분한 테스트를 했으며 프리뷰를 작성했다고 합니다.
아래 공식적인 알파900의 스펙입니다.
  1. 2460만화소 35mm 풀프레임 CMOS sensor (35mm DSLR에서 세계최고화소)
  2. SteadyShot(손떨림보정, 풀프레임으로선 세계최초)
  3. 듀얼 Bionz 이미지프로세서.
  4. 100% 시야율, 0.74x 배율 뷰파인더. 
  5. 중앙 듀얼크로스 9 AF + 주변 10 AF , F2.8 sensor
  6. 5 fps 연속촬영, 새롭게 개발된 미러박스. 
  7. 인텔리전트 프리뷰(Intelligent Preview Function)
  8. 3 User programmable custom memory modes on mode dial
  9. Advanced Dynamic Range Optimizer (5 step selectable)
  10. 40 분할 허니콤측광
  11. 3인치 92.1만화소 포토퀄리티 (270 dpi) LCD display, 100% coverage
  12. Direct HDMI output
  13. ISO 200-3200 (ISO 100-6400 expanded range)
  14. User interchangeable focusing screens (3 options)
  15. CF Type I/II and MS slots, 리튬이온 배터리, 880장까지 촬영가능.
  16. 156 x 117 x 82 mm, 850g (배터리포함 895g)
  17. SR software (새로운 이미지변환 컨버터, 비네팅제어)
  18. 새로운 버티컬그립.
  19. 무선리모콘 제공.
  20. 마그네슘 얼로이바디와 방진방습처리
  21. AF 미세초점조정.
 
최대 6048 x 4032 크기까지의 사진을 얻을 수 있는데, 대형인화를 자주해야하는 상업 사진가분들에겐 이 부분이 무척 반가운 내용입니다. 4스텝까지 보정가능한 SSS(Super SteadyShot)와 중급기 A700보다 향상된 DRO(Dynamic Range Optimizer)...전문가들로부터 좋은평가를 받았었습니다. 그리고 30개 렌즈까지 AF미세조정이 가능한 부분등 사진촬영에 편의를 더하고 있는 최근의 DSLR기능들을 모두 담고 있습니다.  
현재 330만원 선의 가격으로 나오는군요.
