APC lens on a full frame camera
Dec 19, 2012 11:46:28 #
This is probably an extraordinarily dumb question. But what would happen if one of the 18-270 lenses was put on a full frame camera (5D mark II) Would the characteristics remain the same? I read somewhere that an 18-270 would appear like a 27-400? True? Would the sharpness be the same as on an apc camera? Would auto focus and vibration control work?

To my understanding, an efs lens (S for short back focus) moves the rear lens closer to the sensor plane. On full frame cameras, this would result in a vignetted result as the image would be smaller compared to the full frame sensor. The resolution would not suffer and all other functions would still be there.
Also, on some cameras, I believe the clearance of the mirror swing is insufficient to clear the longer back lens mount, which would be a literal train wreck in the camera.

Full frame Canon cameras do not accept EF-S lens mounts without modification.

The 18-270 will look like an 18-270 on full frame. It's on crop sensor it appears like the 27-400

Isn't the 18-270 a crop frame (APS-C) lens?
If that is the truth, then it would look like a 18-270 on a crop frame senor camera and would have would not work well on a full frame camera, unless the camera has a setting to use that lens (like some Nikon (D600, D800, D4?))
But then again, I've been wrong before.

Any EF-S lens will not work on a full frame camera. Attempting to do so would damage the camera, the lens or both.
Having said that - if you have a lens that works on both a full frame and an APS-C camera, it would work like this:
Say you have a 70-200mm lens. Your view on the full frame would be 70-200mm. On a APS-C camera, it would be the equivalent of a 112-320mm view.
However, the view at 70mm on a 17-85mm EF-S lens is the same as the view at 70mm on a 70-200mm EF lens. The focal length doesn't change, the equivalent magnification does because you are capturing a smaller area that the lens is showing.

An APC camera, like the Canon Rebel Crop Senor line, can accept both EF-S and EF lenses. However, a Canon Full Frame Camera, such as the Canon Mark II, only accepts EF lenses. It would depend then on what APC lens you are talking about. Is it an EF or an EF-S mount? http://www.differencebetween.net/object/difference-between-canon-ef-and-ef-s-lenses/

Ahhh the old crop frame lens misconception. The sensor is what determines if there is a crop factor, not the lens. It does not matter if it is a "crop lens" the crop factor applies to all lenses on that camera.

The size of the lens does not change from camera to camera. The size of the image changes going between full frame and aps-c.

The image size made by the lens is the same too.
It's the size of the sensor that changes the angle of view.
Smaller sensor= narrower angle of view. (more "reach" or whatever you want to call it)

The image size would only be the same on the FX sensor if it was cropped to DX size. Correct? In that case you would also be reducing the pixels in the image also
