Canon Lens Image Stabilization
stabilization was first put into a lens from Canon and has since been followed by pretty much all the other manufacturers. If we kind of walked back through the line of history, we can see how it's improved on what's important. So was introduced in 1995 in the 72 300 that has long since been discontinued. And what it's doing is it is employing and boy, I would have hate. I'm glad it was not a lens designer. When somebody says, Yeah, we want to design a lens that has these lens elements that move inside the lenses. You're focusing, all right, So what's happening is as you move the camera, the lens elements for a stabilization will be doing something different than all the other lenses in order to keep the light rays going to the correct spot on the image sensor. And so it's got an independent Giro in the lens that is looking at your movements and doing a counter movement so that the image that ends up on the image sensor is steady throughout that time. At the beginning, it took one seco...
nd to stabilize for this thing to kind of figure things out and it had two stops of control, which means it helps you to shutter speed. Stop slower than you would normally be ableto handful the lens to take a 60 millimeter lands, you would need 1/60 of a second. Now you could shoot it 1/ and down to 1/15 of a second. That's the two stops. As we move along, they added a motew for panning in 1999 the added tripod detection, which is still a little iffy. I still recommend turning it off on a tripod. They increased the speed at which it was able to figure out how to stabilize down too 1/2 2nd and they added an extra stop control, so they able to figure out how to keep it even steadier. 2006. They went all the way up to four stops a control, but he thinks gonna happen next five stops and the added hybridize with trying to explain here in a moment 2011 they added a mode three that Onley did this during the exposure. It helps certain types of sports photographers in panning and watching their subjects the to keep the frame from not moving around too much. So it's something that's used on typically the bigger sports lenses. And then I think maybe this is the most interesting one. In 2014 they actually decided to get certified. And so there is an industry standard. Everything before 2014. It's just cannon over there saying, Yeah, it's good for two stops. It's good for three stops. We think it's good for five stops, a stabilization. And now they actually have to adhere to standards that Nikon and Sony and Olympus and everyone else adheres to. So I kind of think of pre 2014 is in the steroid era, all right. These numbers are all kind of blown out of proportion on lenses, and we'll see this when we get to the list of lenses. So on some of the big lenses they have these 12 and three markings. One is your normal hand held stabilizer on mode, which means as you tilt and kind of twist back and forth, it's going to stabilize your movement. Your your hand movements in the little jitter in holding your camera. The bigger white lenses are gonna have a mode to which is used for panting, cause when you're panning, you don't want the camera to correct for your horizontal movement. You just want it to correct for your vertical movement. And the camera consents, whether you're holding the camera vertically or horizontally and when your camera holding the camera horizontally. What it does is it turns off thank you the side to side movements and so you can pan and keep your subject exactly in the same spot in the frame, you turn the camera vertically. It understands your shooting vertical can sense the motion of the camera and Comptel that you're panning from side to side like that. There is a mode three on a few of their very highest and lenses. This is their newest panning mode, and what this does is it turns off the panning system, and Onley turns it on exactly when the exposure is taken. And even though they had that tripod detection system, they claim, trust me, it's better if you do have a rock solid tripod to turn the stabilization off. However, if it's a little windy, you have an 800 millimeter lands that's got a little bit of jitter on it. You probably want to leave the stabilization on. So the question isn't so much. Is it on a tripod or off a tripod? But is it solid, or is it moving a little bit if it's moving a little bit? The stabilization is something that you can turn on a few of these lenses. Most people don't know about this have what is called dynamic stabilization, and this is four stops of effective range. But it works and it's optimized for shooting video. And these are in Ste. Went late. Is that right? I think these were supposed to be STM. I think I made a mistake on the slide here, folks mark this down. These were supposed to be STM lenses that have this feature on it. Then they introduced hybrid stabilization and this works a little differently. It was the first in the 100. Now it's in 24 to 70. Normally it's looking for movement, tilting the camera up and moving the camera from side to side. Okay, but now the hybrid is gonna look for movements up and down and side to side, which is a different type of movement and was not easy to get but makes these incredibly good for stabilization. And so both of these lenses I would classify as their very best in stabilization. Although it's not the most in stops of stabilization in the types of movements in the ways that you hand hold it, these are among the best performers, in my opinion. So in the group of two stops of stabilization is a bunch of lenses that are fairly old at this point. And in this list, which you'll be able to review later in the pdf, I have put little stars by the ones that are CPAs certified, so these are the current ones that are actually accurate. Anything that doesn't have this little star is a slightly bloated number by Canon, usually by a full stop. And so all of these are three stopped stabilized, so they're all await. Excuse me, if it has a star, it is pre SEPA certified, which means all these three stop ones when they say three stop, it's probably two, maybe 2.5 stops a stabilization. Most of their lenses are four stop stabilizers, and that's pretty consistent throughout the line. The lens that has the most stops of stabilization. Is there five stop? But this is pre certification. So this is the steroid induced number that is probably more like four stops, but it's still really nice stabilization system. And so that's the stabilization system within the canon system of lenses.
