Matched rings/dimensions

The detail that isn't necessarily apparent from the bare specs is that the 25-50's dimensions are an exact match for those of the 10-25mm F1.7. It's the same 127.6mm long and 87.6mm in diameter, and its geared zoom, focus and aperture rings share their sizes and spacing with those on the existing lens.

This commonality means that the 25-50mm can be swapped onto a video camera rigged-up with a follow-focus to mesh with the gearing of the 10-25mm. At 654g (23oz) the 25-50mm is a surprisingly lightweight lens, given all the elements inside. This makes it 32g (1.3oz) lighter than the 10-25mm, but neither lens feels especially front- or back-heavy, so we doubt this discrepancy will be enough to throw off the balance of most gimbals.
