I get my goodies at Ritz, Amazon and Adorama. It helps me keep adding to this site when you get yours from those links, too.

INTRODUCTION

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

In the beginning, Nikon digital SLRs had sensors that only came in one size, called DX.

Life was good. Every lens gave exactly the same angle of view on every Nikon DX digital SLR.

Nikon's DX sensors measure 15.8 x 23.6 mm, while 35mm film and FX digital sensors measure 24 x 36mm. DX sensors are 1.5x smaller than 35mm film. See also Crop Factors.

In 2007 Nikon introduced the D3 digital camera with Nikon's first 24 x 36mm sensor, dubbed FX by Nikon. The larger sensors are needed to get the best results at about 10MP and above, and to get wider wide angles since the only wide angle lens for the DX format is the 12-24mm DX, whose widest angle of view on a DX camera is really only about as wide as a 20mm lens on an FX camera.

 

Lens Compatibility

DX cameras take every lens.

DX lenses have reduced image circles that only cover the smaller DX sensor.

Film cameras can't use DX lenses because the smaller image circle will give black corners at some or all settings. FX cameras usually crop their sensors automatically for the DX lenses and use only the smaller DX inner portion of their sensors.

Often DX lenses can be used at some settings on film cameras, but it's better to use a more appropriate lens.

1.5x Crop Factor (What's a Crop Factor?)

Because these sensors are 1.5x smaller than film, they show an area equivalent to the area shown by a lens 1.5x as long on 35mm film.

A 100mm lens on one of these cameras shows the same area of view that a 150mm lens would show on a 35mm film or full-frame camera.

Multiply a lens' focal length by 1.5 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.

Help me help you         top

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

If you find this 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.

The biggest help is to use these links to Adorama, Amazon, Calumet, Ritz and J&R when you get your goodies. It costs you nothing and is a huge help. 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.

Thanks for reading!

Ken
