Sony 50mm f/1.4

The Sony 50mm F1.4 is the company's current offering in the classic 'fast standard' category, and was introduced at the genesis of the Alpha system in July 2006. Of course its origins go back well before then; this lens is essentially a reworking of the Minolta AF 50mm 1:1.4 RS from 1990, which was itself a restyling of a 1985 design that, alongside the Maxxum/Dynax 7000, formed part of the world's first autofocus SLR system. And that original AF version was itself heir to a long line of manual focus Rokkor lenses dating back many years before. To consumers brought up on the 'use it for a year, throw it away' upgrade cycle which electronics manufacturers (and until recently, credit-card companies) have so encouraged, such longevity may come as a real surprise, making the design seem positively antique. But in truth it really serves to illustrate the maturity of the traditional standard lens formula, which has been refined over many years to a quality level difficult to surpass without a major redesign.

The current Sony 50mm F1.4 has been cosmetically refreshed for the Alpha branding, with smooth rubber grips giving a distinctly minimalist look broken only by a few trademark orange accents. It also adds a couple of useful refinements to the older Minolta design, including modified coatings more suited to the demands of digital SLRs, and the addition of ADI focus distance encoding for improved flash metering. However the underlying design appears to be otherwise the same, and size and weight are hdentical. It features the classic 50mm F1.4 lens formula of 7 elements in 6 groups, with all-spherical lens surfaces. However there is one standout feature compared to similar lenses, a circular aperture diaphragm using 7 rounded blades, again inherited from Minolta's designers who were concerned about the aesthetics of out-of-focus backgrounds long before the internet popularized 'bokeh' as a buzz-word every savvy on-line photographer needed to know (if not necessarily understand, or even be able to pronounce).
