Ideal for digital as well as 35 mm SLR cameras, this is a telephoto macro lens that is capable of lifesize shots. Its floating inner focus system allows high performance. SLD (Special Low Dispersion)glass is used for superior correction of all types of aberrations. The HSM (Hyper Sonic Motor) also provides full-time manual focus.
This gets good reviews on sites such as PhotoZone.de and at this price is excellent value.
