Sony E 35mm f/1.8 OSS Handling and features

Build and design is typical of Sony's E-Mount lenses, with high quality black plastics that sport a glossy finish used for much of the lens barrel construction and a metal lens mount. Despite the very light weight of only 155g, the lens feels very solidly put together. The low weight makes sure the lens will match up perfectly with even the most compact NEX series camera bodies, and it handles very well on the Sony NEX-6 used for testing.

Auto focus is very fast and accurate as a result at distances over half a metre away, but sometimes the lens can struggle to focus adequately on closer subjects. Applying manual focus adjustments is a pleasure, thanks to the smooth action of the focusing ring, which is perfectly damped. Minimum focus is 30cm from the sensor plane, which is fairly typical for a lens of this type.

As focusing is performed internally, the 49mm filter ring does not rotate, which makes the lens ideal for use with graduated and polarising filters. A deep petal-shaped lens hood is supplied as standard, which attaches to the lens via a bayonet fitting.

For those times when slow shutter speeds are necessary, this lens comes equipped with optical image stabilisation. With care, sharp hand-held images can be taken at shutter speeds as slow as 1/6sec, which is roughly three stops slower than the usual rule of thumb for hand-held photography would allow.

Sony E 35mm f/1.8 OSS Performance

At f/1.8 sharpness in the centre of the frame is already very good, and the clarity produced towards the edges isn't too far behind, which is excellent performance for a wide aperture lens like this.

Stopping the aperture down improves clarity across the frame with peak clarity being achieved at f/4, where sharpness is outstanding across the frame.

Resolution at 35mm

How to read our charts The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column. The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple. For this review, the lens was tested on a Sony NEX-6 using Imatest.

Chromatic aberrations are very well controlled, barely exceeding half a pixel width at any most apertures. CA's just exceed half a pixel width towards the edges of the frame with the lens stopped down beyond f/5.6. This low level of fringing should pose very few issues, even in large prints, or harsh crops from the edges of the frame.

Chromatic aberration at 35mm

How to read our charts Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software. Apochromatic lenses have special lens elements aspheric, extra-low dispersion etc. to minimize the problem, hence they usually cost more. For this review, the lens was tested on a Sony NEX-6 using Imatest.

Falloff of illumination towards the corners of the frame is quite reasonable for a lens with a f/1.8 maximum aperture. At f/1.8 the corners of the frame are 1.26 stops darker than the image centre and visually uniform illumination is achieved with the lens stopped down to f/4 or beyond.

A very mild, but barely noticeable amount of pincushion distortion is present in images taken with this lens. Imatest detected 0.981% pincushion distortion, which will be very difficult to spot in normal images. If, however, you require absolutely straight lines, you'll be glad to know that the distortion pattern is uniform across the frame, which should make applying correction in image editing software afterwards a doddle.

The supplied lens hood does an excellent job of shielding the lens from extraneous light that may cause issues with flare. Even without the hood this lens is very resistant to flare and retains good contrast, even when shooting into the light.

Value for Money

Although £400 for a standard prime lens with a maximum aperture of f/1.8 may seem a little steep, especially to owners of SLR cameras, who may compare this lens to a 50mm f/1.8 equivalent, it still represents good value so long as the excellent optical performance of this lens is taken into account. The ace up it's sleeve is the addition of optical image stabilisation. Whether this is truly necessary at this focal length is open to debate, but this feature comes into it's own when longer shutter durations are called for.

As an alternative, Sony NEX system camera owners may also consider Sony's A-mount 35mm f/1.8 SAM lens, which costs around £150 and can be used with a NEX camera with the correct adapter. This route may only suit those who already own a variety of A-mount optics to make the extra cost of the adapter, and extra bulk of the system as a result, worthwhile.

If the fast f/1.8 aperture isn't absolutely necessary for your style of shooting, and you're on a budget, Sigma's 30mm f/2.8 EX DN lens may make a suitable alternative. It's much cheaper too, retailing for around £150.

Sony E 35mm f/1.8 OSS Verdict

Although it seems this lens carries a bit of a premium price, the performance it delivers probably makes it worth it, for those who require it. Sharpness is very good from maximum aperture, and can even be considered as outstanding as the lens is stopped down.

Other optical anomalies, such as CAs, falloff and distortion are also kept well in check, plus the light weight and compact dimensions of the lens should make this an ideal addition to any serious NEX camera owners kit bag. The addition of optical stabilisation can only enhance the appeal of this lens.

The Sony E35mm f/1.8 OSS lens offers excellent performance with optical stabilisation a welcome feature.
