I've got some cracking shoots with mine, handheld used to team it with a 1200d canon, which meant that if was front heavy, with this camera before I learnt my camera properly (went on a one to one days, course) I used to prefer the result from using the sport mode, rather than the Auto seen... I now normally use AV, sometimes I swap to TV depends on what results I'm getting.
I now team it with a 7d mk 2, which balance is so much better and makes wielding around slightly easier.
Two factors for me though, is it's an heavy set up, and I'm an average height female.... I've impressed a few when I've been out, and at times when I'm tracking over head, I've almost come a cropper and land flat on my back,
Another thing that must impact on my picture, I have a crushed nerve in my elbow, plus trigger finger, apart from the issue caused by the trigger finger, I have no feeling as such across half my hand, with the muscles around this area being weaker!
but yes I'm considering a gimbal to go on my tripod, my excuse for this to hubby, is that once I have my ops on elbow and hand, I'm not going to be able to do much strenuous lifting ect for around 2 months at least, so be on sick leave from work, and not able to use my lens due to weight for 2 months, is well gonna turn me from my normal harmless scatty into a psychotic wild women.... Might be wise to purchase if it enables me to take a photo the week after my ops....
