General impressions: Crooked Chinese assembly. Damn, I would tear off my hands. The "lid" of the case (slightly to the right of the accessories attachment) moves away from the case. Do not insert back. On the sony m4 (from a relative), the flash comes out with difficulty, also because of the case. There is also a little glue left on the front of the lens barrel, which is not erased. I buy equipment for a lot of money and I want to get excellent quality, not as luck would have it, but consistently. Honestly, now I understand that it's not worth that kind of money. I advise you to take a closer look at canon / nikon. Sony is not the same anymore :( Yes, only because of the case. I consider this unacceptable.
