Is the Tessive shutter just the same as a mechanical shutter? If I have a mechanical shutter, like on the Sony F65, is there any reason to use a Tessive shutter?
The Tessive shutter's function is very different from what a mechanical shutter does, but this is a good question. For a full answer to this question, we did a test of our shutter compared with a Sony F65's mechanical shutter. The results and explanation can be seen here: tessive.com/mechanical-shutter-comparison.
