Stabilizes my Sony A7 with a 28mm lens very well. However, the 24-70 lens adds too much weight and front loading. The good thing about this model, however, is that it can be adjusted in the app for the weight of the mounted camera and lens. However, if your lens is too long, you will need to balance the camera body far enough back that you lose tilt axis capability. Although the adjustment plates have dimensions for each axis (so you could theoretically get the balance right and then write down the adjustments next time), it still takes me quite a while to set the initial balance before turning it on. I've used this about 5 times and overall have been very happy with the results.
