On land it is 140° AFAIK, but the flat port kills it as well as the corner IQ. Actually doing more research I ended up buying the g140, unpacked it yesterday. At first look it appears to have an aspheric element, which is key for good IQ across the entire frame and which is missing from all "cheap" solutions (domes, simple air lenses such as the meikon wide wet lens). I'll come back with tests as soon as I receive the compatible dive housing and can lay my hands on some waterproof iso resolution charts.
