The other unusual statement about the lens is that the zoom and focus design minimises breathing (desirable) and axial shift – well, I’ve not seen a zoom with axial shift, image wandering off centre when you zoom or focus, since the days of pioneering 1970s consumer glassware. Especially not a non-stabilised zoom, like this. Stabilisation has been the main reason any lens shifts off axis.
The lens weighs 488g which is great, takes 72mm filters which is not great but matches some other Sony lenses, and the size as you can see from the images here is convenient though not a single PR image sent to me shows it with a lens hood which could have some impact on bag/pocket ability. One thing’s for sure, if the dual linear motor focusing is as good as claimed, f/4 will not be a big loss over f/2.8 and carrying one lens in place of two will make this a winner for travel, landscape and urban shooting. It’s due to be in UK stores from March 3rd.
