Samyang 24-70mm f/2.8 AF Zoom Lens (Sony E)

Build quality is excellent, which is something of a bonus given the budget price-tag.

This lens has a dust and moisture resistant design that is sealed in seven different places which makes it well-suited to life in both the field and the studio.

The Samyang AF 24-70mm F2.8 FE lens has a metal lens mount. It accepts 82mm filters via metal threads.

There is a fairly wide and textured focus ring at the end of the lens. There are no hard stops at the ends of the range, making it harder to set focus at infinity. Polariser users should be pleased that the 82mm filter thread doesn’t rotate on focus.

The lens utilizes a Linear STM (Stepping Motor) for smooth auto-focusing, and it’s very quiet in operation making it well-suited to shooting video.

When it comes to auto-focusing, this lens is a fairly quick performer, taking about 0.20 seconds to lock onto the subject when mounted on the Sony Alpha A9 that we tested it with.

We didn’t experience too much “hunting”, either in good or bad light, with the lens accurately focusing most, but not all of the time. It’s also a quiet performer, which makes this lens equally well-suited to both video recording and more candid stills shooting.

The Samyang AF 24-70mm F2.8 FE is equipped with a Custom Switch on the side of the lens barrel. Essentially you can use it to program the focus ring, with Mode 1 setting it to Manual Focus and Mode 2 turning it into an Aperture Control ring. Samyang are also promising that more functions will be added in a future firmware update.

This lens does not feature optical image stabilisation, so it relies on the camera body’s own built-in stabilisation, which is fine unless you’re an owner of an early Sony Alpha camera.

The Samyang AF 24-70mm F2.8 FE lens is commendably supplied with both a soft drawstring bag and a good quality plastic petal-shaped lens hood which twists into place.

Chromatic Aberrations

Chromatic aberrations, typically seen as purple or blue fringes along contrasty edges, are not too much of a problem with the Samyang AF 24-70mm F2.8 FE lens, except in areas of very high contrast.

Vignetting

With the lens set to its maximum aperture of f/2.8, there is some light fall-off in the corners, requiring you to stop down by at least 3 f-stops to completely prevent it.

Distortion

The Samyang AF 24-70mm F2.8 FE exhibits a lot of both barrel and pincushion distortion, as you can see in the photos below, which will you need to correct in post-processing.

Sunstars and Flare

The Samyang AF 24-70mm F2.8 FE is capable of producing fairly nice sunstars when stopped-down to f/16 or f/22, as shown below, and the lens isn’t very susceptible to flare even when shooting directly into the sun with the supplied lens hood fitted.

Macro

The Samyang AF 24-70mm F2.8 FE is not really a macro lens, but it does offer a usefully close focus point of 0.35m / 1.15ft across the entire zoom range from the sensor plane and a maximum magnification of 0.27x when set to 70mm.

Bokeh

Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc.

Samyang have paid close attention to this aspect of lens use, employing a 9-segment diaphragm with rounded blades for more pleasing bokeh.

In our view, their efforts have been pretty successful for a standard zoom lens – see the examples below to judge for yourself.
