Introduction

Ease of Use

Weighing in at 524g, the hybrid metal and engineering plastic bodied Sony 35mm F1.4 GM is very light for such a fast, full-frame lens.

Compared to the Sigma 35mm F1.2 DG DN Art, which is one of the biggest and heaviest 35mm prime lenses that we've ever tested with a weight of 1,090 grams and measuring 13.6cm in length, the new Sony FE 35mm F1.4 GM is much easier to live with.

It's substantially heavier than the Sony FE 35mm F1.8, though, which at 281g is a whopping 143g lighter than this new F1.4 version.

It's also a lot more expensive too, to the tune of around £900 / €1000, so you really need to make sure that you'll benefit from the faster maximum aperture to justify the substantial extra cost.

Its overall size is fairly well-suited to a camera like the Sony A7 III that we tested it with, as shown in the photos below, although with the supplied hood attached it is quite imposing for a 35mm lens.

It measures 76 x 96mm, making it both smaller and lighter than the comparable Distagon T* FE 35mm f/1.4 ZA lens, which is 16mm longer and weighs 106g more.

Build quality is excellent, certainly up to the high standard of the other flagship G Master lenses in the range.

It has a sealed dust and moisture resistant design, although Sony stops short of saying that it's 100% weather-proof.

The Sony 35mm 1.4 GM lens has a metal lens mount and it accepts 67mm filters via metal threads on the front of the lens.

The lens has a customisable focus hold button which keeps the lens locked to the current focusing distance, useful if you're auto-focusing and don't want the lens to try and find focus again. It can also, amongst other things, be usefully set to Eye AF.

The lens doesn't feature built-in optical image stabilisation, relying instead on the camera body's stabilisation system.

The Sony 35mm 1.4 GM lens has a fairly wide, ridged focus ring. Manual focusing is possible by using the focus mode switch to toggle between AF and MF.

There are no hard stops at either end of the range, making it a little more difficult to set focus at infinity. Polariser users should be pleased that the 67mm filter thread doesn't rotate on focus.

The Sony FE 35mm F1.4 GM lens has not one but two XD linear motors which produce very quiet and smooth focusing, making it well-suited to shooting video, with the overall lens length remaining constant during focusing.

When it comes to auto-focusing, it proved to be an almost silent, very quick performer on the Sony A7R III camera that we tested it with. We didn't experience very much "hunting", either in good or bad light, with the lens accurately focusing almost all of the time.

Sony's near flawless Eye AF works perfectly with this lens, quickly locking onto and tracking the subject's eye despite the wide-angle view.

The Sony FE 35mm F1.4 GM lens features an aperture ring that has 1/3EV stops ranging from f/1.4 to f/16 and an Auto setting.

The Click switch on the bottom-right of the lens barrel lets you select whether the aperture ring clicks into place at each aperture stop or rotates smoothly for silent operation during movie recording.

The Sony 35mm F1.4 GM lens is commendably supplied with both a soft case and a very good quality, plastic, circular lens hood (ALC-SH164) with a locking button and a rubberized edge to help protect it.

Focal Range

The 35mm focal length provides an angle of view of 63 degrees on a full-frame camera.

Chromatic Aberrations

Chromatic aberrations, typically seen as blue or purple fringes along contrasty edges, were not very apparent in our test shots, only appearing in very high contrast areas. The example below shows the worst-case scenario.

Light Fall-off

With the lens set to its maximum aperture of f/1.4, there is some obvious light fall-off in the corners, requiring you to stop down by at least 3 f-stops to completely prevent it.

Distortion

There's just a little pincushion distortion evident in the RAW files - the Sony Alpha A7 III automatically and successfully applies corrections to the JPG files.

Sunstars

The Sony FE 35mm F1.4 GM is capable of producing quite nice sunstars when stopped-down to f/16, as shown below.

The lens is slightly susceptible to flare when shooting directly into the sun, though, even with the supplied lens hood fitted, but it's mostly well-controlled.

Macro

The Sony FE 35mm F1.4 GM isn't claimed to be a macro lens, but it does usefully offer a minimum focusing distance of 27cm with a maximum magnification of 0.23x, increasing to 25cm and 0.26x when focusing manually. The following example demonstrates how close you can get to your subject.

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.

In the FE 35mm F1.4 GM lens, Sony have employed an iris diaphragm with 11 circular blades, which has resulted in very appealing bokeh for a moderate-wide-angle lens.

We do realise, however, that bokeh evaluation is subjective, so we've included several examples below for your perusal.
