The 50 mm f / 1.4 works wonders on the DSLR Alpha 850 and 900. In fact, after two years of practice, I can say that this view of the "standard" (for the 24x36 format) and at the same time, more useful, strictly nothing to envy its counterparts Nikon, Canon and Leica. From f / 2, the results are of the highest level in RAW format developed by DxO Optics Pro. The combination of the quality of the optics and the automatic correction of the software, not only the distortion, vignetting and CA but premiums optimization dive, provides unsurpassed results in this FF format. Highly recommended.
