Sony has a reputation for being very proprietary minded. As such, I've found that the best equipment to interface with a Sony camera is Sony equipment. This is an opinion formulated years ago. Sony may have changed, but I'd still lean towards Sony equipment and not mix and match.

That is true Bob except on the NEX line and the newer a6000, a6300 and a6500, just about any flash will work, I use a vintage Minolta flash on mine, I would pick the Opteka because of the price, But I would bet the Sony is a better built flash.
