Brilliant for Video when using manual lenses
With the Pentax Asashi lenses on Panasonic GH4 it does fit very tight and there is no loose play at all. It also keeps things in focus, allows you to focus to infinity and seems rather well sealed - I didn't test it in stormy weather tho.One thing worth noting, it does not have anything electric to it, so you'll have to focus manually.It does feel very intuitive, both the installation and the usage.Strongly recommend if you can't afford the speedbooster.
