The folks at DPReview.com have posted their report on the Sigma 50mm F1.4 EX DG HSM standard lens which can autofocus on the Nikon D40/40x/60 entry-level DSLRs. Their verdict: itâ€™s a sharp lens with class-leading image quality, low vignetting, fast autofocus with full manual override and very good quality.
Its price at $500, however, might make you think twice. But is it worth $500? You bet. Reviewer Andy Westlake suggests to wait a little while for its price to drop to the level of other similar lenses (this Sigma 50mm is still very much at the start of its product cycle â€“ it was introduced at $730, MSRP), â€œthen it will be quite simply a steal.â€
The Sigma 50mm F1.4 EX DG HSM lens is available for Nikon, Canon, Pentax, Sony and of course the Sigma mounts.
