Canons
I Invested in a Canon 10D about 7 years ago.
Spent allot of money on the lens - a canon Ultrasonic one for faster focus.
Its the best camera i have ever owned, taking pictures Instantly ( theres no delay ) like many non slr cameras.
I opted for the Extra battery pack which fits on the bottom ( looks like a D1 ) so it take 2 batteries.
Its only 6 megapixels, but its the quality that counts at the end of the day.
Theres other variations, i think the latest one is the 40D ?
