Sony fights back! 400-800mm G and 16mm f/1.8
Well, a couple of days after Sigma announced their new 300-600mm f/4 to much acclaim Sony has pulled the rug slightly from their feet with a £2,549 400-800mm ƒ6.3-8 G OSS supertele zoom. Like Canon, they have realised current mirrorless sensors can focus easily with small apertures on long lenses

The saving in cost is matched by a saving in weight – 2.4kg is good for a big white lens in this class, rugged and weather-sealed (they claim ‘fully’) and with optical stabilisation to take over from I.B.I.S. which would be at the limits of movement at 800mm. As adding converters… it works with both 1.4X and 2X.

Viltrox inspiration?

The new 16mm f/1.8 is hardly surprising when Viltrox in China has made such a groundbreaking lens and taken the market by storm. Sony’s G response even fairly priced by its standards at £849 RRP, and at 304g it’s a striking 246g lighter than a bigger Viltrox. It’s also much smaller but still a full-frame f/1.8. It focuses down to 13cm and has a declickable aperture ring with an unusual iris lock switch to prevent change of setting. It takes 72mm filters. It lacks the A-B focus change movie function or clever (fault prone?) LED display of the Viltrox, but has a regular multi-function button. At £300 more than its independent predecessor it should become a standard addition to pro and enthusiast kits alike.
