Manufacturer description

This macro lens is ideal for digital SLR cameras as well as film SLR cameras. This lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor.

The Macro 105mm F2.8 EX DG lens is very suitable for taking close-up pictures and it enables the use of natural light conditions or flash. The greater working distance of this lens is very advantageous when taking pictures of flowers or insects.

Depth of field of medium telephoto macro lenses is generally very shallow; however, Sigma, Canon and Konica Minolta mounts of this lens have a minimum aperture of f/45 (f/32 for Nikon and Pentax mounts) for incredible depth of field.

A screw-in hood is included, for convenient use of circular polarizing filters. It is possible to attach an 77mm filter in front of the lens hood.

This lens also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during auto focusing. The large focus ring offers smooth and positive action while focusing manually.

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 77mm filters but must be removed to mount the dedicated lens cap or a 58mm filter.

Notes

The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3500, D5000-D5600 digital SLR cameras.
