Is there any reason to buy a brand name canon grip over a different brand grip? Looking through the "features" I don't see anything that is different but wondering what I am missing.
I have three grips at home. 2 third party grips ( both Opteka, one for the good 'ole Rebel XT that my kids still use and abuse, and one for the 30D that they also use but I keep a watchful eye on as it is my backup). My other grip is a Canon for my now defunct 40D (grip still works perfectly). I personally see no difference in actual use...they have all done (and still do) what they are supposed to. I do prefer the matching surface texture and logos of the Canon grip, and suspect that resell value for the camera with a Canon grip would be higher than with a third party grip. I'm likely going to go for a Canon grip for my 7D but I would be comfortable with an Opteka if budget was an issue for that item.
