INTRODUCTION

Canon makes cameras with three different sized image sensors.

Full-frame digital cameras use a sensor the same size as 35mm film.

Consumer 1.6x cameras have a sensor 1.6x smaller than 35mm film.

These 1.3 x cameras use a sensor 1.3x smaller than 35mm film. These cameras are the professional Canon 1D series, which includes the original Canon 1D, the Canon 1D Mk II, today's Canon 1D Mk II N and the Canon 1D Mk III.

The sensors in these cameras are 19.1 x 28.7mm. 35mm film is 24 x 36mm.

 

1.3x Crop Factor (What's a Crop Factor?)

Because these sensors are 1.3x smaller than film, a lens used on these digital cameras shows a smaller angle of view. See Crop Factor for explicit details.

I rounded these to the nearest mm, and I used the more formal factor of 1.255, which is 43.267mm / 34.475mm or 1.255 (the ratio of the formats' diagonals.)

 

Ultra-Wide and Fisheye Lenses

Sadly there is no way to get real ultra-wide results with these cameras.

The 1.6x cameras can use EF-S lenses, and the 10-22mm EF-S lens designed for them. EF-S lenses don't work on these 1.3x cameras.

That leaves the widest lens as the 14mm f/2.8 L, which for $1,800 gives the same view as an 18mm lens on a 35mm film camera.

The $1,500 16-35mm L is used my most pros with the 1D, which gives the same results as a 20 - 44mm lens on a 35mm film camera. Settling for a 20mm equivalent is OK, but sadly that's as wide as you get.

The 15mm Fisheye isn't very fishy on the 1.3x cameras because they crop and only use the middle of the image.

I'm not a fan of Sigma, but their unusual Sigma 12-24mm f/4.5-5.6 EX DG Aspherical covers a full 35mm film frame and gives an equivalent of 15 - 30mm on the 1D, which is worth a look if you own a 1D.

 

EF-S Lenses

EF-S lenses do not work on 1.3x cameras.

These are special, shorter lenses designed especially to take advantage of the smaller sensors of the 1.6x cameras.

These lenses don't make an image big enough to work on the 1.3x (1D series) or full-frame or film cameras.

 

Help me help you         top

I support my growing family through this website, as crazy as it might seem.

The biggest help is when you use any of these links to Adorama, Amazon, eBay, Ritz, Calumet, J&R and ScanCafe when you get anything, regardless of the country in which you live. It costs you nothing, and is this site's, and thus my family's, biggest source of support. These places have the best prices and service, which is why I've used them since before this website existed. I recommend them all personally.

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!

If you haven't helped yet, please do, and consider helping me with a gift of $5.00.
