I absolutely agree with you Maiz - I bought a battery grip with my Digital Rebel - it was $99.00. After learning that Canon BP
-511 batteries are close to $70 a piece, I looked on E-Bay. I wound up getting two BP
-511 generic batteries, and they seem to last much longer than the original Canon battery does. I was able to buy the pair for $19.95, and I'm extremely please with them. Now I have two fully charged batteries in my grip, and one more in the bag!
If you are considering the battery grip, but are skeptical about it - go to a camera shop and try one out. The camera feels much better with it. I bought a side strap for mine, and it feels great. It feels very secure in my hand, and even with a heavy lens like the 75-300 IS USM
, it's still quite manageable even with one hand. A sidestrap in my opinion is a must!
Also, nobody's mentioned the array of buttons and dials that are on the battery grip! There is a shutter / focus button, On/Off switch (enables the buttons on the battery grip), AE
lock button, AF
point selection button, and even a main dial to select and change settings. It's great to have all of that at your fingertips when shooting vertically!
