Manfrotto BeFree Compact Travel Carbon Fiber Tripod

I love this tripod. It was my "go to" travel buddy when I recently went on vacation to Hawaii. I wanted to get photos of me with my wife on Oahu. And, this little baby did the trick. It is flimsy, but worked just fine when I needed to use it. My camera is quite heavy with a normal lens, but this little gem could withstand the weight! And, the best part is it is super light weight. We took it everywhere we went. It comes with a great carrying bag as well. Well worth the investment! I highly recommend it!

The ball head is 218 grams (including the quick-release plate). If the quick-release plate is on your camera, then the ball head alone is 188 grams. I weighed it on my kitchen scale.

When using the Manfrotto BeFree Compact Travel Carbon Fiber Tripod, the "ball head" does not have a smooth pan feature.

The head is removable and either of the heads you mention will attach.

Yes, the Manfrotto BeFree Compact Travel Carbon Fiber Tripod is compatible with the Sony A7RII, depending on what lens is attached. With a capacity of 8.8 pounds, the BeFree tripod will work with the Sony A7R2 camera with most lenses that are offered. If one were to attach a 8 pound lens to the Sony camera, it would not be compatible.

Of course any ball head will work

I don't know for sure, but I can't imagine the ball head won't fit - it's a standard mount. This is a very light weight tripod though, and I wouldn't use it as a primary tripod. It's great to strap onto a backpack when you can't bring a heavier set, and it is extremely compact.

This tripod has a minimum working height of 13.4 inches.
