comment:I picked this up at my local camera store as part of a new Sony A7II retail kit for $100 more than the body-only sale price. The original list price was $500, but it seems to have been permanently reduced to $400 last year after briefly being on sale for $350. It normally costs $200 extra in a camera kit. "Made in Thailand"

On the A7II this lens is equivalent to a 18-50mm F2.3-3.7 zoom on APS-C--comparable to Fuji's XF 18-55mm F2.8-4 or a 14-35mm F1.8-2.8 zoom on Four-Thirds. It is considerably larger than the APS-C E-mount kit lenses but about the same size as the little Minolta AF 35-70 F4 on an adapter.

The rear element is very recessed. The optical design looks like it could have been used on an SLR. It would have been a tiny SLR zoom lens. The most retracted focal length is around 48 mm like the Minolta 28-80 D and 28-100 D zooms, but it extends much less at the extremes than either of those zooms.

The 70 mm end is much tighter than the Minolta 35-70 F4 and even a bit tighter than the Tamron 28-75 F2.8.

The exterior is smooth matte black plastic and rubber. It is nicer to touch than the metallic finishes on the APS-C lenses like the 18-55 OSS.

The plastic petal hood uses a similar two lobe bayonet like the Sony DT 35 F1.8 and 85 F2.8 SAM lenses and will mount on those lenses.

This is yet another underrated E-mount lens. Image quality is very good. The long end is a bit soft wide-open especially on the 24 MP A6000. The 18-55 OSS is sharper at the long end in the center.
