Sigma Fitness Tracker

Although the most expensive of the fitness tracker watches, it worth it for serious trackers. Highly recommend.

The tracker works without any weights only with a light load, like a Sony A7x class camera, a VERY light and compact ball head, and a light (and slow) lens, like a Loxia 21mm f/2.8. The total weight must be less than 3.3 lbs, or you will end up ruining the tracker. If you use a more normal ball head and a lens like the Venus Optics Laowa 15mm f/2, you will need one of these counterweights. If you use a heavier lens like a Sigma 14mm f/1.8, then one weight is not enough – you will need two. Also, for a Sigma 14/1.8, I would also recommend a support bracket to minimize vibrations, and that would add its own weight. So you will need two counterweights. And lastly, if you want to shoot the Andromeda galaxy with your 600mm f/4, you will probably need three, maybe even four of the counterweights. So buy as many as you need, depending on your use case. The counterweight itself is made well - it's as compact as it can be, without going to heavy metals like lead. It has a nice finish and easy to handle. The screw knob works well. And yes, you can use it to crack walnuts and it hurts if you drop it on your toe.
