I don't think I made a mistake buying a Sony. We just had a firmware update to the A7 line. One of the few things (few compared to Fuji) the firmware did was to speed up the start up time to get the camera ready to snap the first picture. I notice quite a bit of difference. There were some other minor tweaks. Nothing on the scale of what Fuji did. So, either Fuji was way behind other manufacturers and needed to catch up, or they're just trying to build brand recognition. Either way, I say it's a plus, but I don't expect them to continue in that vein. They would go out of business. My hats off to them for giving this "freebie" to current customers. I almost bought a Fuji, but I wanted a full frame sensor, and a good one, and Sony has probably the best sensor out there. Fuji is still in the DX phase of their development, but we'll see what happens. I think it's way too early to say which manufacturer will be leading the pack when all is said and done. My brains tell me Sony coming out with a PRO line of mirrorless is pretty serious stuff. I would have to say if Sony lives up to it's hype with the Pro line, and indeed professional photographers begin to use the Sony Pro line, the battle for the mirrorless will be close to being won by Sony. Still, Fuji, has a long way to go to catch up to full frame bodies that Sony first introduced. I don't mind giving kudos to Fuji for a great firmware release. I wish that all camera makers would do the same, but they won't. I'm just happy that Sony came out with a firmware update for their current A7 users right before they announced a new and improved a7 II. You can't rule out Olympus either since they're right at Sony's doors with a 4/3's brilliant camera too!
