The Exakta AF 35-70mm 1:3.5-4.5 MC is a rebranded Sigma product (AF Zoom Master 35-70mm MC), an inexpensive first-generation AF lens released in 1988 for all popular 35 mm SLR autofocus systems of the day. It has a 35 to 70 mm focal range of rotary design and minimum focus distance of 50 centimeters. The rotating front element is threaded for a 52 mm lens hood or filter. Weight comes in at about 335 grams with both end caps.<br><br>On Nikon bodies, the lens relies on the camera's in-body AF motor and consequently cannot autofocus on cheaper models in the D3xxx or D5xxx lineup. It also predates the AF-D standard and exposure therefore may not be as accurate in certain situations such as when using fill flash.
