ePhotoZine have reviewed the Sigma 70-300mm F4-5.6 APO DG MACRO lens, which offers macro photography with a 1:2 maximum magnification at the 300 mm focal length.

“The extended focus, providing the 1:2 macro facility, is especially useful and performed well giving good definition at close quarters. The new multi-coating, which gives the lens it’s DG (optimised for digital) classification, helps a design that is good to start with, that extra bit of help in controlling artefacts. CA is well controlled and distortion reasonably well managed, although there is a slight pincushion effect at the 300mm end. (Easily cured in software on digital images)”
