Now I've been playing for a while with the idea to occupy myself once with interval and time-lapse photography, which is why I have the offer to try this tripod head gladly accepted. Unfortunately, I have dealt me closer after this order it. If I have understood this correctly, the exposure must be in interval shooting at each image in advance to be checked and corrected if necessary, because the so captured images afterwards when they are compiled on the PC, all need to fit together. This is not so easy with a tripod head, which rotates slowly to himself. Again, I think a normal tripod head with graduation for more suitable.
Conclusion: Enter at this point prefer the money saved here for a better quality of the ball head for your tripod. You will then be happy with other recordings on your purchase.
