I recently replaced my Mi Photo tripod ball head with the Acrotech GP-SS with lever ball head. It's just came in the mail this week so let's go ahead and open it up. Very simple box no fuss numbers. Got pieces of instructions. Just a piece of foam. I'm going to move to the side and inside is the ball head. So this is the ball head. It really feels just full-on metal. The reason I thought I'd do a quick video on this is because I really didn't find many videos about this particular ball head. There's the one that's larger than this, essentially more for pro-level cameras and then there's this one. This is kind of like the pro line that they have. The reason I replaced the Mi Photo Ball head which kind of sort of did a good job. It's in use right now and with one on one of the cameras is because the levers essentially are a metal lever with a rubber plastic ring around it to help tighten the lever. The problem is it would kept slipping and I could never really tell that it was fully tightened or not. So I didn't like that piece and then I also didn't like that it had the screw to constantly screw the arcuswist plate in and out because I used my camera with an L plate and I really wanted to use both the bottom and the side pieces so both in horizontal and in vertical mode. So this essentially fit the bill saw some really great reviews about this particular company AcroTech. All the stuff is really well machined and also made in the US so why not. Anyways so here it is. What you can see here is well it's first measure of the weight. How much is the weight? Now we can start in ounces sure. So with the quick release plate it's 14 and a half ounces or 410 grams exactly. So to give you an idea about how much it weighs I know the Mi Photo one weighs less but not by much. Man Frodo has ball heads that have a lever released to him but they're just so hefty and I think the one that I had was almost 800 grams all on its own so I decided to get this one instead. This main screw tightens and loosens the actual ball head so if you let go you can move it around. It has a little bubble level up top for the quick release plate up on the top. There's the spacer that makes it smaller and larger so the plate has a locking lever on top that you can push on one side. To unlock goes all the way around and you can remove the quick release very easily. To lock it you just twist it towards the other way until you hear it click then it's locked will not unfasten. It has a little pin in here to prevent the quick release plate from sliding around. This particular bolt in here is actually quite nice because not only it is that have an Allen it also has a flat. I've tried to replace quick release plates on a lot of different camera ball heads and inside the Allen just keeps getting stripped. On this side is a smaller knob. This particular knob essentially determines how loose the ball head is when it is not fastened tight. So if I unfasten this it's out essentially all the way. It's supposed to be fully loose. If I let go of this all the way and it's extremely loose. If I tighten this it still will move just much less. The last adjustment knob that's left on here is this particular knob and this knob is for the panning. So unscrew that the hole had just pans. Now one of the things that I haven't really fully tried out yet but I think I kind of got the hang of where the ball head you see it has a little notch in the ball itself right there. That notch specifically fits into a groove and and locks the ball now in place. Now that now the head is not moving side to side is very stiff so you can I guess technically tighten it up and have your camera on an L-plate or whatever and still do vertical panoramas. I haven't tried this out yet. The last trick that I still haven't tried out is essentially that the plate here can be removed then this particular base mounted to the tripod and the plate itself mounted to the top here and that's supposed to allow for the ability to do rotations pans like this. At the top I'm not sure I just don't understand why this is much better or much different or more beneficial and maybe somebody can let me know then just doing it in this orientation like this as long as you got the top right here leveled straight and maybe that's the problem. You can't level this maybe. I don't know. Maybe somebody can tell me. But so anyways so far so good it had extremely fast shipping on amazon.com the link I'll leave down below definitely was not a cheap ball head. There's a million different ball heads out there and you know everybody has their own budget and their own requirements to work through but I have ended up purchasing so many different items as duplicates that in the end I just wanted to buy one ball head and use it for a very long time so I didn't want a massive ball head I wanted it to be just big enough for essentially my A7R2 with a 780 to 200 lens on it and I think that this will more than do the job. I'd rather keep the kit as light as possible and this Acrotec GPS S ball head will fit the bill and I'm sure I'll come back and talk about it later on again but this is the first such review and let me know what you think.
