It's a new thing to me, although I took photos earlier, but I always had compact fully automatic machines with some programs. I always interested in how it really works, but I didn't spend time to understand it, but nowadays my friend gave me his old Canon 20D to try and learn.
The old Canon EF-S 18-55 objective worked, but sometime it dropped "Error 99". I searched the Internet, and ordered a cheap flex ribbon cable to it. Since I have changed it, the "Error 99" have gone to holiday. So my equipment is working well, I can try to take interesting photos.
