I recently bought a used D300 along with some accesories. The camera worked like new, So I wanted to take it out for a spin.. I took about 700 frames of timelapse footage with the optimal settings (or what I considered optimal when checking the frames in-camera).
I was not impressed at all, I understand tha the D300 is much older than the D7100 that I'm used to at the moment.
I felt like I had no choice than to get rid of it, fortunately I managed to get the same amount from it, than what I paid.
Now, come sunday, I'll be getting a used D7000..
Oh, also, I bought Kenko's extension tube set.
