INTRODUCTION

Adorama pays top dollar for your used gear.

I use these stores. I can't vouch for ads below.

Canon has made cameras with three different sensor sizes: full-frame, 1.3x, and the cameras listed below with the smallest 1.6x sensors.

The cameras below have a sensor 1.6x smaller than a 35mm film frame. Canon also calls these the APS-C sized sensors.

The dimensions of the sensors in these cameras is about 22.2 x 14.8 mm.

These cameras are the:

1.6x Crop Factor (What's a Crop Factor?)

Because these sensors are 1.6x smaller than film, they show an area equivalent to the area shown by a lens 1.6x as long on 35mm film.

A 100mm lens on one of these cameras shows the same area of view that a 160mm lens would show on a 35mm film or full-frame camera.

Multiply a lens' focal length by 1.6 to get the focal length of a lens which, when used on a full-frame or 35mm film camera, gives the same angle of view as that lens does on one of these cameras.

Examples:

(I rounded these to the nearest mm, and I used the more formal factor of 1.62162, which is 36mm/22.2mm.)

 

EF-S Lenses

These are special, shorter lenses designed especially to take advantage of the smaller sensors of these cameras. These lenses don't make an image big enough to work on the 1.3x (1D series) or full-frame or film cameras.

The older 10D, D60 and D30 were invented before EF-S lenses, and unfortunately the EF-S lenses wont' work on these cameras. You should have turned these camera relics into your local police or fire station years ago anyway, sorry.

If you find this page as helpful as a book you might have had to buy or a workshop you may have had to take, feel free to help me continue helping everyone.

If you've gotten your gear through one of my links or helped otherwise, you're family. It's great people like you who allow me to keep adding to this site full-time. Thanks!
