STANDARD 33mm CAMERA LENSES

SLR (single lens reflex) cameras are undeniably the most popular cameras on the market. They are small, light and easy to use ... and produce great results.

MANUAL SLR CAMERAS

• Manual wind-on when loading and between each frame
• Ideal for the technically minded
• The Viewfinder shows the scene that will be recorded - no matter which lens is used
• Manual focus, allowing the photographer to decide which are of the image to concentrate on

AUTOMATIC SLR CAMERAS

• Automatic film loading and wind-on and frame wind-on
• DX recognition of the film speed
• Automatic focus and exposure - this can be overridden
• Auto-exposure that is ideal for those not clever or interesting in making technical decisions 
• Auto-focus which is useful for photographers with poor eyesight or being used in low-light situations

STANDARD LENS

• ​A 50mm lens is fitted as standard on most SLRs
• Useful for most subjects.  It often has a wide maximum aperture that makes it good in low light
• Will not show the distortion that can occur with wide or long lenses - and its angle of view is similar to that of the human eye

      
        50mm is a standard lens for 35mm cameras
        28mm is a common wide-angle lens
        80mm is a common long-focus lens

LONG-FOCUS LENS

• Angles of view is 80mm - 300mm
• The subject is shown as very large, making a long lens ideal for distant subjects or detailed close-ups
• Depth of field decreases as the lens get longer

WIDE-ANGLE LENS

• Angle of view is generous, and the depth of field at all apertures is extensive
• Keep away from poor quality wide-angle lenses.  The will show distortion at the edges of the image

ZOOM LENS

• These allow one to fine-tune the subject by adjusting the focal length of the lens
