Back Side Controls: AE-L, AF-ON & Rear Command Dial
[John]- Next up, on the right hand side of the back of the camera is the auto exposure lock button, and this is gonna be used any time the camera is setting part of the exposure for you, whether it's in a complete program mode or shutter priority, aperture priority style mode. If the camera is controlling something, you can just simply lock in the exposure. So let me take a little example here, I'm gonna set my shutter speed to A, I'm gonna set my lens aperture myself so that I have this set, and what you'll notice is I'm gonna set F8, the camera is choosing a shutter speed of a fifth of a second. But as we move this around you can see my shutter speed is changing a bit. If I wanna keep that locked in, I just press and hold the AEL button, and you can see that there's a little blue indicator down here, exposure lock, and the numbers are locked, and as soon as I release my finger, the numbers are moving around and it stays locked in whenever I keep my finger pressed on that button. Now ...
this AEL button is a button that can be reprogrammed and so if you don't use the auto exposure lock function, well, you can change it. And the way you change it is by going in to the set up menu in to the function settings, and changing that particular parameter and adding some other feature to that button. And there are different ways that you can work with the lock mode. Some people like to use the press and hold technique that I was just showing you, some prefer a toggle technique, where you press it once, it locks it in, and you press it once again to release it, so there's a lot of different customizations that you can do with that button and the rest of this camera. Next up is the Auto Focus-ON button, we talked a little bit about this in the back Button Auto Focus option, and so this is a focusing button that out of the box it doesn't do ya a lot of good, because the camera is always refocusing when you press down on the shutter release. If you really wanna harness Back Button Focusing what you need to do is you need to go in and turn off the Auto Focus on the shutter, and so you can do that by going in to the menu system and turning off the shutter AF under the button dial setting. Now one of the things that's kind of unique about Fuji that I really do like in this particular case, is that when you have the camera in Manual Focus, this AF-on button works as a immediate auto focus override, and so by turning the dial on the front of the camera to M for manual, that is another way of just simply putting your camera in Back Button Focusing, without diving in to the menu system at all. And so, it's a great option for somebody who likes to manually focus but every once in a while, wants to Auto-Focus from time to time. It allows you the freedom of doing that without diving in to the menu or making any other setting adjustments at all. The Rear Command Dial is a general purpose dial that is used for a large variety of things, and so turning it changes Program Shift, Shutter speeds and more, but it is also a Press button that you can use for a variety of types of things. And once again it also has a secret little shortcut here, is that it can change the way that the manual focus is being done, and so that's probably where a quick little demo here for ya. So what I'm gonna do on this one is I'm gonna put the camera in to a manual focus mode, so on the front of the camera, I'm gonna make sure that this dial is in Manual Focus, and then on the back of the camera, what I can do, if I want to manually focus you can see I have the scale down here at the bottom, and I can see in the view finder, kind of, it's not real big, but if I press in on this, I can zoom in and now, let's see if I can zoom in and out, but then if I can turn to get a little bit closer, let's move this down a little bit so that we can see what we're focusing on, and now I have a better idea if my subject is in focus. And so I just pressed this once to zoom in, and then turned it to get either closer or not, and if I press and hold in again I get to a digital split image which should work really well on the edge over here so watch what happens. Let's see if, that's not so clear, it's splitting the image, I'll show ya a better example in video here but that vertical line is giving splits, it's working the way the old split image view finders in SLRs work. It's the digital version, it's not as good. And then there's Focus Peak Highlighting, which will have subjects that will shimmer a little bit as they come in focus as you can see the edge of that frame getting a little bit brighter. This is something that can be customized and adjusted, so I can hold in for two seconds, and change it back to standard so that it's just a punch in to get nice and close to our subject, and so if you like to manually focus, there's a lot of quick options for changing how you can do that manual focus. Over on the right side is a little indicator lamp that basically says that your camera is working in most cases. It has some indications about whether the focus is locked, whether you're recording to a memory card, whether it's kind of waiting for something or charging, and if any sort of errors so just be advised that means the camera's working.
