Sony's New SAL55300 zoom lens is an all-purpose telephoto lens for Sony's line of A-Mount cameras. It zooms considerably further than the existing 200mm SAL55200 for just $100 more. For a $300 lens, 5.5 times magnification is impressive zoom. As for other specs, the lens opens all the way up to f/4.5 when it's zoomed out or to f/5.6 when it's zoomed in. The lens will mount directly onto both Sony's DSLRs and its recent, excellent SLT cameras. To get it onto NEX cameras like the awesome F3 you'll need to use an adapter. This budget beast will be available in September. [Sony]
