NIkon D300 và Canon EOS 50D nên chọn mua cái nào?

The next question was how the camera would work out in the field. To photograph flying birds belongs to the most difficult and most challenging you can expose a camera for in terms of AF.

The new EOS 50D with EF 300 / 2.8 IS and EF 70-200/2, 8 IS with and without 1.4 TC managed for the most part to follow the Gulls which flew after the boat or who flew at me when we anchored. If i aimed correct and gave the camera few tens of a seconds to react i always got sharp images. When it was not sharp, it was I who had missed having the bird in the centre. I used AI SERVO AF with only the central focus point active.

To further test the AI Servo i tried to shoot with all AF points activated. I also stopped down a bit to further increase the DOF. To my surprise, the new EOS 50D with 70-200/2,8 and 300/2.8 worked quite well following birds even with all the AF-points activated. I do not think it works always, but this was clearly better than in any previous camera, I tried.

The speed of 6.3 images per second is sufficient to be able to capture the eagle wings in different positions. My experience tells me that the critical point is located somewhere of about five pics per seconds. Is the speed higher than you can capture wings in different positions with most birds, including birds of prey and owls.

Compared to MKIII with the ten pic per seconds it is of course a difference, but in practice it is rarely i would miss the images because to lover 6.3 FPS.
Back in my hotel room I checked the image files. Unfortunately I had been forced to take photographs in JPG format, since none of the RAW converters didnt work with the 50D files. The files were larger than I had expected. I had expected a 12-13 mpix sensor but the 50D have 15 mpix.
