ePhotozine has just complete the full review on new released Sigma 85mm f/1.4 DG HSM Art Lens for Canon EF mount (B&H Photo Video & Adorama.com & Amazon.com), tested on Canon EOS 5D Mark IV DSLR camera, the new Sigma 85mm f/1.4 DG HSM Art lens turns out very sharp and easy to use.
The Sigma 85mm f/1.4 DG HSM Art lens is a high class, highly competent design that performs confidently and efficiently. It is of the modern breed of 85mm lenses, sharp from open aperture, as opposed to older designs that were intended to be softer wide open for the purposes of flattering portraits. This new lens is sharp throughout, although not cruelly over-sharp, so subjects should be pleased enough.
It is also delightful to use, the only omissions being vibration reduction and weather sealing, but the performance itself is not in question.
