Multi Interface Shoe, Audio, Focal Plane
Next up we got the top of the camera, which has the well we used to call this the Hot Shoe, but now they've installed special electronics in here, and it's the Multi Interface Shoe, so yes you can mount flashes on there. Let's talk about that first. The camera does not have a built in flash, if you do wanna add a flash. We're not gonna go through all the different flash units available from Sony, but here is a little secret about photography that a lot of people don't know, is that Sony along with Canon and some other manufacturers, they name the flash by the power rating of the flash, and so the number is a direct relationship to the power of the flash. And so you can see how powerful that flash is by that number. Now Nikon doesn't use this so don't apply this to all the manufacturers. But it does apply here in their guide number of the flash in many cases. So there's lots of different flashes available, if you do need to add light to it. But because of the extra electronics in there,...
we can also use that for other reasons to power other devices. And so as we all know, Sony is also big into video cameras. All which means they need to be into audio. So if you wanna hook up a dedicated mic onto the top of the camera, you're gonna have electronics in there, so you're using the camera's battery power, not necessarily batteries in the mic itself. We do have stereo microphones, which are better than nothing when it comes to recording movies and sound on your camera. So you do get stereo sound but you are limited any time you have it built into the device itself like this without any shock absorbers. It's also not so good in wind, but we do also have a speaker on the top of the camera, so that when you play your movies back, that's where that sound is coming from. And finally on the top we have our focal plane, if you wanna know where the sensor is in the camera, if you were ever to need to measure this for exact focusing reasons whether it be with a Sony lens or a Macro lens. That's where you measure it to. Most people will never need it, but that's what it's there for.
