Manufacturer description

This 50 mm macro lens enables high imaging performance. Due to the floating mechanism, this lens can photograph objects precisely not only at life-size reproduction but also at infinity. Background blurring is possible with this lens, due to its f/2.8 aperture and it can also reproduce images without detracting from the solidity and beauty of the subject. As the front of the lens does not rotate during focusing and the hood is screwed in, you can easily use circular polarizing filters. This lens has a minimum aperture of f/45 (or f/32 for Nikon and Pentax mounts) that increases the depth of field when desired.

From the editor

The overall length of the lens increases considerably with focusing from infinity to the closest distance. The front element is deeply recessed inside the lens barrel which eliminates the need for a lens hood. Nevertheless, Sigma offered deep circular screw-in lens hood as a part of the package. The hood has threads to accept 72mm filters but must be removed to mount the dedicated lens cap or a 55mm filter.

The lens was also sold under the name QUANTARAY 50mm 1:2.8 MACRO.

Notes

  • The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3500, D5000-D5600 digital SLR cameras.
  • Sigma had to reverse engineer the communication protocol of the Canon EF mount to produce a version of this lens for Canon EOS 35mm film SLR cameras. As a consequence, this lens may not work properly with Canon EOS cameras (both film and digital) due to compatibility issues.
