Hi there, I'm pretty sure I'm not the only one that had the problem.
If you want to go from a prop body camera to a full frame camera, then you're pretty
afraid of the cost because, I mean, let's face it.
The lenses are really expensive and if you spend a lot of money on a camera, you don't
have the money normally to buy a lot of new lenses.
So there is a certain way how to put prop lenses on full frame bodies.
But everything I'm going to show you right now, you do on your own risk.
So if you damage your camera, your warranty will be void with this approach.
So keep that in mind, I've been using this method for a while now because I wasn't able
to afford all the new lenses.
So let's get to it.
So this is our setup.
We have a 5D Mark IV full frame body.
We have a 24-105mm EF lens and a 10-22mm EF-S lens.
I will show you now the differences between the EF lens and the EF-S lens and how to put
the EF lens on the full frame body.
So stay tuned.
Let's start with the EF-S lens.
If you take a look at the lens itself, there is a white square on it.
The white square in Canon's system tells you that it is an EF-S lens.
Those lenses are just made for the crop body DSLR cameras.
And normally, if you take the cap off, you have this plastic mount.
Basically, this is the main reason why you cannot fit an EF-S lens on a full frame body.
So let's head over to the EF lens.
So if you examine the EF lens, there is a red dot on it.
The red dot shows you that it's an EF lens.
If you take off the cap on the EF lens, you'll notice that the plastic cover is not as high
as on the EF lens.
So here you can see the white square and the red dot.
So the top of the EF-S lens is the thing that is preventing you from using these lenses
on the full frame bodies.
Let's take a look how the EF lenses are connected to the full frame bodies.
So as you can see on top, there is the red dot that indicates that you need to align
the red dot to put the lens on the camera.
On the crop cameras, you have red dot and the white square.
So you can use both lenses, but you have a crop of 1.6 with the Canon cameras.
So when you now try to put an EF-S lens on the full frame body, this is what happens.
So now I align it and it won't go in.
So this part of the lens is what's your problem.
What solution is there to put this lens on the camera?
It's a pretty simple one.
If you have a zoom lens, the most important thing is you don't want to scratch the lens.
Let's go to the narrowest angle you can go.
Take your finger, grab the cap and pull.
And this is what comes out.
Now you take the body, you take the lens, align it and see, snaps right in.
Perfect.
If you use the 10-22mm lens and you go to the widest angle,
you'll notice that the lenses are a bit outside of the body.
If you look at it side by side, the same thing does not apply to the EF lens.
So if you do this modification, you do it on your own risk.
What could happen is if the lens is too far out and you take a picture and the mirror is snapping,
the mirror could hit the lens and could damage the mirror.
So keep that in mind.
You can totally use it with 12mm, but I wouldn't recommend to go to 10.
Now I'm going to show you how the crop lens is affecting the pictures on the full frame body.
I've set up a little test picture for you guys.
This setting right now is with 22mm.
If I go up, you see that the picture is getting a really wide angle.
Where I'm pausing right now is with about 15mm.
As you can see, they're slowly starting to appear a black ring outside.
And this is because the lens isn't big enough to support the big sensor of the full frame body.
There is a sweet spot where you won't get the black ring.
And you have a really, really wide angle lens with this lens.
And now let's come to the catch.
If you use the 5D Mark IV and you're recording movies in 4K,
the camera has a crop of 1.4.
So if you use that lens and you go into a wider angle,
you won't have the black ring around.
So now I'm at 12mm.
And as you can see, you have a beautiful wide picture.
A little darker edges, but not too much.
It's perfect for video making.
I used this setup on the travel vlog.
So basically most of the selfie videos I did, I did with this lens and this camera.
So this is how I got basically a very good start with the full frame body and the cheaper EF-S lens.
