Unboxing the Lens
UsedPhotoPro packed it well with plenty of paper padding, and bubble wrap. The lens itself was wrapped in a plastic bag with a rubber band to hold it flush. No complaints!| The lens and some of the paper packaging below it. |
First Look at the Lens
| UPP's "Good" rating details as of the publishing of this article. |
They had the lens rated as "Good" (75 to 89 percent). The zoom ring feels pretty smooth, but the focus ring is a tiny bit loose. It could be how the lens is normally. Totally fine though I might as well mention it. The lens feels within their rating description.

It came with a third-party front cap and an official Sony rear cap. Overall, the lens looks good from the back, and the glass is clean. For the price of around $300 shipped, I think it was a decent deal.
| The glass is in good condition. |
Comparing this Sony 16-70mm f/4 to the Sigma 18-50mm f/2.8
On the Sony a7S I tested it in both APS-C mode and full-frame mode.
There’s an obvious difference in exposure, f/4 on the Sony versus f/2.8 on the Sigma. I bumped the ISO up from 640 to 1000 when switching to the Sony lens to get them looking similar. The background won’t look quite as nice with the f/4 lens, but I can still get a decent look from either lens.

I did notice that there’s a little less distortion on the Sony at its widest setting compared to the Sigma, which is a nice benefit. Plus, the Sony has built-in optical stabilization, something the Sigma doesn’t offer. However, the Sigma lens lets me get closer. Tasks I do like showing products on camera makes that useful.
Thoughts on UsedPhotoPro
I’ve used UsedPhotoPro before, and have had positive experiences overall with them.The deal seemed good enough I rushed to buy the lens. I wasn't intending to order an APS-C lens and was thinking the focal length range could apply with lenses like the Tamron 17-50mm f/4 Di III VXD that exist. Their website didn’t have an option to cancel the order. Since it was a weekend, I wasn’t able to get in touch with them after sending a message through their website and an email. The did respond on a weekday, but the lens had already been sent.
Considering it was my mistake and any equipment I have access to for review to is useful to my work, so I’ll probably keep it for a while. If I'm able to get an FX30 in the future this would be a nice combination.
Final Thoughts
The Sony 16-70mm F4 OSS appears to be a nice lens in my limited testing. If you need optical stabilization or want that extra zoom range compared to the Sigma 18-50mm f/2.8, it's an option to consider.If you’re more interested in a faster aperture, then the Sigma f/2.8 might be the better choice. I also think the Sigma's autofocus motor is a bit better for video work than the Sony's.
Both lenses have their pros and cons, but either one would make a good addition to your kit depending on your needs.
