This was a good showdown with the Sigma 85mm f/1.4 EX Vs. Bell & Howell 85mm f/1.4. Both lenses are extremely good but both give options for your needs. In the end if you need auto focus go with the Sigma 85mm f/1.4 EX DG HSM but if you are on a budget and can manage a manual lens, it seems the Bell & Howell 85mm f/1.4 Aspherical IF MC has a slight optical edge. You can also look on Ebay to see if there are split focus screens that will help you manual focus the Bell & Howell lens.
This Sigma 85mm f/1.4 EX DG HSM is a fantastic lens for the price with quick focus, sharp photos and really nice bokeh producing some really nice portraits. For a while I went crazy telling everyone around me to go out and buy one because they are so good.
