Most Nikon DSLR have a tethered capture option, however I haven't come across any of them that controls the zoom of the DSLR.
I guess the zoom is controlled manually by rotating the ring on the lens.
On the web I have come across several attempts of controlling the zoom by mounting a motor on the camera with a belt that wraps across the zoom ring.
Something like this.
My first question
Are there any off the shelf solutions for auto zoom control ?
Additionally I tend to shoot a lot of objects that are static but different in sizes.
Is there a zoom to fit option available for DSLR's where I can autocompose and the object fits in the frame with the proper zoom level?
