Contax 645 Camera Lenses

Outfit Your Contax 645 Camera With Advanced Lenses

The Contax 645 began as a medium-format camera within the Zeiss line back in 1932. This camera eventually led to a larger brand name that produces several products now. If you own a 645 camera and would like to get some lenses for it, eBay has a range of options from which you can choose.

What lenses can the 645 accept?

Although some lenses are intended to work with the 645, the camera can use an adapter to accept lenses from other brands as well. Your 645 may be able to use lenses from the following brands with the help of an adapter:

• Hasselblad - This Swedish company began over a century ago and has produced cameras in the medium-format range since the 1940s.
• Leica - Leica modified some of its earlier products and changed them into photography equipment.
• Zeiss - A German manufacturer that started the Contax line with a single model.

What aperture limits can you choose?

All lenses have a maximum aperture setting. Manufactures display this setting as the letter "f" followed by a whole or decimal number. You can see the manufacturer's site for details on this setting. Larger openings have lower numbers and can allow more light through. The lower the number, the faster the lens can perform. Note that fast lenses may be more expensive than their slower counterparts. Some common aperture designations you might find on eBay are:

• F/2
• F/3
• F/3.5
• F/4

What focus types can you choose from?

Some lenses are designed to be used with particular focus settings. You may wish to choose one that works for the focus type you use most often with your camera. Some common focus types you can find on eBay are:

• Auto - The lens will adjust its focus as necessary to make the subject clearer. You will often find the term "AF" printed on the sides of these products.
• Manual - You can use your own judgment to bring a subject into focus with this setting. You'll need to do this for each shot.
• Combo - This feature allows you to switch between auto and manual focus as necessary.

What focal lengths are there?

A lens with a long focal length presents a narrow angle of view and greater magnification than one with a shorter focal length. Some focal lengths you'll find on eBay are:

• 35 millimeter
• 45 millimeter
• 70 millimeter
