Nikon D3X is too expensive, which leaves me with no reasonable choice but to think about the Canon EOS 5D Mark II when it comes to the next upgrade. Or I can stick with my two year old Nikon D200 until there is an affordable D700x… Please note this is a continuously updated post.
Black dots problem
- The Internet is buzzing about a strange problems showing up in high contrast night scenes: there are black dots appearing to the right of a bright spot, such as street lights, Christmas lights, etc. Example can be found here. This happens even at ISO 200. One guy reported that he could get rid of or at least reduce the occurrences by turning off highlight tone priority, lighting optimizer, and noise reduction. However he wasn’t convined in follow-up posts.
- Here is one trying to be funny about the situation:
I cried because I had black dots – and then I met a man without a 5D MKII at all!
As I’m still waiting for mine, if you want to unload your horribly flawed MKII I will buy it at the black spot discount price.
Since the dots basically render the camera useless… 30% off retail?
