Are any of you using a battery grip on your DSLR, and do you find that it improves your handling of the camera (I am not asking about its ability to increase number of pictures being taken before battery change)?
Yes and yes. I have relatively small hands, but with a T3i I much prefer the balance and additional heft of the camera with a battery grip.
My wife has a T2i, I got her a grip along with it based on my own preferences and she's never even tried it. I think it is a very personal thing.
Perhaps for me it relates back to my film camera days with a Russian Zenit E which was pretty hefty, a Canon AE-1 which wasn't, and then a Canon T90 which was affectionately known as "The Tank". I just prefer a slightly heavier camera, and the additional bulk makes it easier for me to get a more stable shooting stance. If tripod stability is an issue, then the grip is easily removed, but I have never found that to be a problem with anything except long lenses, when I mount the lens, not the camera, on the tripod anyway. Handheld, the bigger and longer then lens the more I prefer the additional mass of the camera with the grip attached. This also relates to mirror less cameras for me. They may be technically excellent, but I don't like the feel of them.
Unsolicited additional comments related to power usage and other considerations.
I do however find the additional battery life a big advantage, especially for video or live view usage which tends to eat batteries very fast. I have never used the AA battery holder, never even taken it anywhere with me, but it's nice to know that it is available if I'm going somewhere where it could be required.
I use Magic Lantern on my T3i. It adds a significant number of features that I find useful, some of which only work in the energy sucking Live View mode such as focus peaking and so on. I use some adapted Canon FD lenses, including a Canon FDn 500mm reflex lens. The use of LiveView combined with the additional functionality of Magic Lantern gives me 'mirror less camera-like' focusing aids that are very useful with a lens that has a fixed aperture (f/8.0), a very thin DOF and is a total bitch to focus with an equivalent 35mm field of view of an 800mm lens. The additional battery life is useful with that.
For video, if indoors with a tripod and appropriate circumstances, I use an AC power supply if possible.
In summary, I like the tactile feel and mass of the battery grips, and when power consumption is an issue, I prefer not having to think about it any more than necessary. On the other hand, I do not generally find that weight is an issue, as some on UHH do.
Finally, since I consider the grip to be part of the camera, I bought the more expensive Canon grips rather than cheaper third party alternatives. My thinking was that I wanted the grip and the camera to feel identical from a tactile texture perspective as well as things like build quality and other considerations. Since I use it all the time the additional cost wasn't really a consideration.
Good luck, I hope some of this is helpful.
