I was just wondering if the live focus feature in the Canon 20Da is a hardware change like the different IR filter is or if is purely software... you would think it would be software. You can download the 20Da firmware but it appears to be in Japanese.
It won't work because the mirror on the 20Da is semitransparent, allowing simultaneous viewing through the eyepiece and the LCD.
So I just got back from the desert, and I took about 500 photos. The only problem with my new camera is that it takes photos so quickly. With bracketing it really adds up quick. I got some great photos including 2 separate run ins with desert tortoises. I am sorting through them now.
Today I bought myself a big birthday present. I picked up a Canon EOS 20D, with the Canon EF-S 18-75mm USM lens. I also bought the battery grip and a Manfrotto 3021BN with an Arca-Swiss monoball B1 head. Here is one of the first images I shot. I really love this camera and have been planning on buying it for a while. I am really looking forward to taking nature photos this weekend!
