The Gadget Bag: Lens Adapters
We talked a little bit about this when we talked about Mirrorless lenses. And that is Mirrorless lenses have a short flange distance, which allows us to mount different types of lenses on our camera. So they're gonna have their own native lenses but if we don't want to use those, we want to use another brand of lenses, especially one designed for a single lens reflex we're gonna be able to mount it on there if we use one of the adapters. And so we can take that adapter, mount it on the camera and mount our lens on it and be able to utilize it. Now, for sharpness reasons this works out very well because as I showed you before these adapters don't have any glass in them, typically for this situation. Where this becomes an issue is in the communication between the lens and the camera body. Does it focus? Does it meter? Does it do all the other features that the camera does? And there's gonna be a variety of answers depending on what camera, what adapter, and what lens you're hooking up he...
re. Because you're starting to hook up devices potentially from three different companies that all have different standards that may not be communicating in any way at all. Alright, so there are a variety of adapters out there that you can get for working with the different cameras. And there's gonna need to be more and more adapters because there's so many different types of cameras and lenses out there. Now there's a special type of adapter called a Speed Booster in general terms. So, what we have is a full-frame lens but we have a cropped frame sensor down here. So if you remember what happens with full-frame lenses and cropped centers is that we kind of overshoot and we're only using a middle portion of the image here. So if you had a camera for let's say a full-frame Canon or an Nikon camera but you were putting it on let's say a micro forth or its camera like an Olympus or a Panasonic camera you're kind of wasting a lot of this image space. What they have is a Speed Booster, which looks very much like a tele converter. And in some ways it's kind of a reverse tele converter. And what it does when you mount it on your camera is it kind of acts like a flashlight if you've ever had a flashlight that can focus the light into a smaller beam. What happens when you take light and instead of spreading it out you narrow it in? It becomes brighter. So there's two things that this does. One, is it regains the wide-angle capability of a lens, because now we're squeezing this back down into the frame. But it also is a brighter light source and it increases your aperture. It let's more light into the camera and this is a really cool thing for anyone who's using a small-frame camera. 'Cause you can buy a large full-frame lens, put the Speed Booster on it and be able to shoot at point F1.0 or below. One stops or two stops better. And so this is gonna increase the brightness and it's gonna regain the wide-angle capability. However, all of these have glass in them. So it's going to affect the image quality a little bit. How much it degrades quality depends on the devices used. We also have to transfer all the electronics. We're probably going from one camera brand to a different camera brand adapter, to a different camera brand lens. And so once again we got three different components, which is multiplying the opportunities for some sort of problem to arise. So when it comes to these adapters and boosters, which are designed mainly for Mirrorless cameras. Can you put and SLR lens on a Mirrorless camera? They have lens adapters to do that, they may or may not have a Speed Booster. It depends on the product you're using. You can't put a Speed Booster on a full-frame camera with a full-frame lens. You've got to have something that has a smaller sensor on it. The communication between the body and the lens, well that's gonna depend mostly on who makes the adapter and exactly what they did. Some have zero communication at all. And so if you look at a price for one of these that seems too good to be true you better look really closely at what it does. Will there be glass elements in there? In the Speed Booster, there definite will be. For the lens adapters there may or may not be. Depends on what they're doing. There's a number of adapters that will have a little something else that they're gonna do. Not only are they gonna allow you to adapt the lens but they're gonna make it be a 1.4 converter for instance. Or they're gonna do something else in there that changes the optical formula of what's going on. And as far as increasing the light gathering, that is specifically what the Speed Boosters are doing. The lens adapters don't. It's just the same normal aperture setting. And as far as increasing the wide-angle ability that is something that you're getting specifically with the Speed Boosters. Remember, you're only using these if you're using something smaller than full-frame. Now their exception to that rule is, is basically that your sensor is smaller than the coverage area of the lens. It's possible, theoretically, I don't think it exists right now, someone can tell me I'm wrong but if you had a full-frame camera like a Canon or a Nikon, there could be a Speed Booster where you take a Mamiya RB 67 lens designed for medium format and you mount that in front of your Canon or Nikon camera. 'Cause that's designed for a much larger image area. Or something for a Hasselblad, you could stick that on your camera. So it's possible it's just that the lens needs to have a wider coverage area then the sensor. So what's cool about this is just being able to make use of all the different tools that are out there.

Love love all John Greengo classes! Wish to have had him decades ago with this info, but no internet then!! John is the greatest photography teacher I have seen out there, and I watch a lot of Creative Live classes and folks on YouTube too. John is so detailed and there are a ton of ah ha moments for me and I know lots of others. I think I own 4 John Greengo classes so far and want to add this one and Travel Photography!! I just drop everything to watch John on Creative Live. I wish sometime soon he would teach a Lightroom class and his knowledge on photography post editing.!!! That would probably take a LOT OF TIME but I know John would explain it soooooo good, like he does all his Photography classes!! Thank you Creative Live for having such a wonderful instructor with John Greengo!! Make more classes John, for just love them and soak it up! There is soooo much to learn and sometimes just so overwhelming. Is there anyway you might do a Motivation class!!?? Like do this button for this day, and try this technique for a week, or post this subject for this week, etc. Motivation and inspiration, and playing around with what you teach, needed so much and would be so fun.!! Just saying??? Awaiting gadgets class now, while waiting for lunch break to be over. All the filters and gadgets, oh my. Thank you thank you for all you teach John, You are truly a wonderful wonderful instructor and I would highly recommend folks listening and buying your classes.

I don't think that adjectives like beautiful, fantastic or excellent can describe the course and classes with John Greengo well enough. I've just bought my first camera and I am a total amateur but I fell in love with photography while watching the classes with John. It is fun, clear, understandable, entertaining, informative and and and. He is not only a fabulous photographer but a great teacher as well. Easy to follow, clear explanations and fantastic visuals. The only disadvantage I can list here that he is sooooo good that keeps me from going out to shoot as I am just glued to the screen. :-) Don't miss it and well worth the money invested! Thank you John!

Wow! John is THE best teacher I have ever had the pleasure of learning from, and this is the most comprehensive, eloquent and fun course I have ever taken (online or off). If you're even / / interested in photography, take this course as soon as possible! You might find out that taking great photos requires much more work than you're willing to invest, or you might get so excited learning from John that you'll start taking your camera with you EVERYWHERE. At the very least, you'll learn the fundamental inner workings and techniques that WILL help you get a better photo. Worried about the cost? Well, I've taken courses that are twice as expensive that offer less than maybe a tenth of the value. You'll be much better off investing in this course than a new camera or a new lens. I cannot reccomend John and this course enough!
