Sony SAL1650

The constant f/2.8 aperture is the main event, landing in the 84th percentile, but the optics are a disappointing 21st percentile. You get great light gathering and bokeh at the cost of sharpness and any modern features like stabilization. It's only worth considering if you find it at the very bottom of its $298 to $948 price range.

Let's talk about that f/2.8 aperture. It's the star of the show here, and it's constant, meaning you don't lose light as you zoom in. This puts it well above average for its class and is the main reason anyone still hunts for this lens. The Super Sonic wave Motor does an okay job with autofocus, but it's nothing special, landing right in the middle of the pack. You'll get the shot, but don't expect it to keep up with fast, erratic movement.

The real pain point is the optics. A 21st percentile ranking is disappointing. You're going to see softness, especially wide open, and the lack of stabilization means you'll need to keep your shutter speed high to avoid blur, which kind of defeats the purpose of having that fast aperture in lower light. It's a lens with a great engine and a foggy windshield.

Stacked against the Sigma Contemporary 18-50mm f/2.8 DC DN, the Sony looks ancient. The Sigma is sharper, better built, and designed for modern mirrorless systems. The Tamron Di III 17-70mm f/2.8 adds stabilization into the mix, which is a killer feature the Sony completely lacks. Even the Canon EF-S 18-135mm, while slower, offers a much more useful range and better optical performance. The Sony's only real card to play is that constant f/2.8 aperture on the cheap, but you're making a lot of sacrifices in sharpness and features to get it.

Pricing for this lens is all over the map. We've seen it listed from $298 up to a frankly absurd $948. At the low end, if you can snag it for around $300, you're getting a fast zoom for peanuts, and the optical flaws are easier to forgive. But anywhere near the $900 mark, you're getting into territory where modern, sharper glass from Sigma or Tamron absolutely destroys it. The value proposition lives and dies by which store you're buying from, so shop carefully.

The Sony SAL1650 is a weird one. It's a constant f/2.8 zoom that lands in the 84th percentile for aperture, which is genuinely impressive for an APS-C lens. You're getting bright, consistent light gathering across the entire 16-50mm range, and that translates to strong bokeh, sitting in the 81st percentile. But here's the catch: the optical quality is a real letdown, ranking in the bottom quarter of all lenses we track. So you've got a lens that's great at letting light in, but not so great at doing anything pretty with it.

It's built for Sony's A-mount system, which feels like a ghost town these days. The autofocus is middling, the build quality is nothing to write home about, and there's no stabilization. At 576g, it's not a brick, but it's not exactly light either. For portrait shooters on a budget, it scores a decent 59.5 out of 100, but if you even think about macro work, just walk away. It scored a 19.3, which is one of the worst we've seen.

Anyone who values sharpness should look elsewhere. The optical quality is in the bottom 21st percentile, which means your images will be soft, especially at that wide f/2.8 aperture you're buying the lens for. If you don't have an A-mount camera with in-body stabilization, the lack of any lens-based stabilization is a deal-breaker for handheld shooting in anything but bright light. Macro shooters should also skip this entirely, given its abysmal 19.3 score.

The Sony SAL1650 is a one-trick pony, but it's a pretty good trick if you're on a tight budget. That constant f/2.8 aperture is the only reason to buy it. If you're still clinging to a Sony A-mount body and find one for under $350, it's a massive step up from a kit lens for portraits and low-light work. But for anyone else, the poor optical quality and lack of stabilization make it a tough sell. There are simply better, more modern lenses out there that won't leave you fighting soft images.
