Excerpt: I bought this for the 7d rather than looking to an off brand knowing that it could potentially screw up my camera. For the price I thought it was way too much though. One thing that confused me was that there was not a AF Control Button...there was no way for me to manually choose my focus point shooting vertically. I had to press the focus point selector located on top, then scroll around with my Aperture dial and shutter speed dial to select a point..
Pros: Lightweight, Reliable
Cons: No Focus Selection Dial, Unreliable Contacts
Excerpt: Functions mostly as designed. Focus/shutter release button is very sensitive. The multi-controller is near impossible to operate in vertical orientation and the overall feel of the grip is very bulky. I'd like it to feel a little more like the normal grip.
Excerpt: I have tried this and third party grip as well, I was thinking to choose this one but it didn't convince me enough with that price... I can buy pretty good third party for third the price with pretty good build..... Only thing I was looking in Canon Battery Grip was WEATHER SEALING where battery door sits.... but Could not found... I usually use my camera in harsh weather condition.....
Excerpt: i like this not only for carrying my batteries but becasue when i shoot vertical the shutter button is at a conveinant place.. also it has storge with in the pack to store the cover i had to remove to plug in the battery pack. it is heavy but durable..
Pros: Clever storage of cover, Easy To Install, Long-Lasting, Reliable
Excerpt: I bought this to use for sports photography with a 7D and 70-200 2.8L zoom, which are big and heavy. Previously used a 10D with battery grip and liked the balance and vertical shooting options. This is very similar but not quite as comfortable to hold, and it adds weight to the already-heavy 7D/70-200 combo.
Excerpt: I'll divide my review into two separate parts, one about the product itself and the other about it's functionality. Whoever is looking for buying a battery grip I believe that main issues are whether or not it's worth the investment and choosing among brands. First of all I decided to buy it to extend battery life by adding an extra one and also have more comfortable vertical grip. I chose Canon branded grip even though it's more expensive than others.
Excerpt: has most buttons you would need, and is easy to use, but the shape of the grip is not at all like the comfy 7D grip. If you bought the camera because of how it felt in your hand, this will not feel as good.
Excerpt: I like the fact that I can have twice the battery power for long shoots. However, I wonder if the non-Canon brands are just as good. If I had to do it over I think I would have purchased one of the non-Canon brands. [...] I don't think this is a bad product I just think the others probably work as well for less than half the money. It seems pretty durable except for the switch that is used to open the bay for the batteries.
