Your lens and Simple terms

LENS
One of the most important features of your camera is your lens. One of the most common misconceptions is that all camera lens are the same. This is not the case. Digital camera lens are not the same as a regular 35mm film lens. The framing area for a digital camera is smaller than that of a 35mm and if you have a DSLR your lens are not interchangeable with your 35mm. and the same goes for your 35mm is not interchangeable with your digital.

In digital photography as in 35mm photography there is terminology to help explain different events that happen when you are taking a photo. Checking out Wikipedia on Line here are a few terms.

Blown Highlights
If you ever took a photo and had areas of pure white, you have what is called blown highlights. Digital cameras record the brightness of a photo in 256 different shades, white being 0 and the black being 256. When you get the blown high lights then your camera cannot read color so it records white. If there is no light then the camera will record black. To make sure that you don’t receive these effects on your photos make sure you use a light meter and set your f-stop accordingly. Many photo editing programs can correct this.

Depth of field
This is simply how much of the scene you are shooting will be in focus. If you are shooting macro image then the depth of field is shallow and only the close up object will be shown and the background will be blurry. For Landscapes you want as much of your scene in view. Your depth of field is controlled by the aperture setting of your camera.

    Aren’t the Canon EF (not EF-S) lenses compatible with both digital and 35mm EOS cameras?

    Shelly, I have checked the Canon website and although it appears that the lens are interchangeable it does not state that they are. SO I would check with the Canon Customer Support for your answer.
