Sony E Pz 18-105mm F4 G Oss Lens Review

Introduction

Specifications and Features

Debuting back in 2013, the Sony Due east PZ 18-105mm F4 G OSS is a moderate-speed E-mount zoom designed for the Sony APS-C format mirrorless models. Intriguingly, it features the old Minolta Thousand-moniker implying high-end optical construction on par with Canon'south L serial and Nikon'due south ED range. Equally the equivalent to a 28-164mm zoom, it has a 5.8x zoom range and features ii ED drinking glass elements and no less than 3 aspherical surfaces. Information technology is, yet, the inclusion of optical stabilization, a constant /f4 maximum aperture throughout the range, and a power zoom choice that shows it is a zoom that is particularly suited to video users.

As well the fixed or variable-speed zooming and constant maximum aperture, information technology has a stepper-blazon focusing motor, and circular discontinuity opening consisting of 7 blades for rendering rounded highlights and smooth transitions to out-of-focus areas when using differential focus. The optical construction consists of 16 elements in total arranged in 12 groups, and a minimum focus distance of 1.48' (45cm). With a 72mm filter diameter, the lens measures 4.33 x three.07" (110 10 78mm) and weighs fifteen.06 oz (427g). Information technology is available for around $599 (USD).

Expert center sharpness throughout zoom range

With a DxO Marking lens score of 15 points on the Sony A6000, the PZ 18-105mm is a solid performer overall, especially given the zoom range. Information technology has good center sharpness on the 24-Mpix A6000 throughout the range, and relatively high 9 P-Mpix sharpness.

Edge and corner sharpness are lacking, withal, and even when stopped down, the sharpness in the centers rarely extends beyond the frame. Information technology also has rather high levels of pincushion distortion (somewhat unusually from 18mm onwards), and some troublesome chromatic aberration at either finish of the zoom range, from 18-24mm and and then reoccurring at 105mm. Fortunately, this is restricted to the corners, merely information technology occurs at all apertures.

Sony PZ E xviii-105mm F4G OSS vs. Sony Zeiss Vario-Tessar T* E 16-70mm F4 ZA: Good sharpness

The two lenses perform at a like level, which is encouraging for the PZ xviii-105mm F4. It even has slightly higher peak sharpness and tin can maintain sharpness at longer focal lengths. Information technology is sharper centrally at f/4 at 50mm than the Zeiss and still has good central sharpness at 105mm, as we mentioned previously.

At f/5.6 however, the two perform similarly, with the Sony PZ 18-105mm exhibiting a very slightly wider fundamental core of sharpness at the longer focal lengths. However, the Zeiss is superior at 35mm, where it performs outstandingly well for a zoom. Nevertheless, that's arguably not that significant for zooms like this. At T4.5 versus T4.3, the Sony is marginally slower, which is slightly disappointing, and of course the Sony has higher distortion and more than noticeable vignetting at the longer end of the zoom (50-70mm) than the Zeiss. It too has college levels of chromatic abnormality at the wider cease, though information technology is restricted to the farthermost corners.

The Sony PZ 18-105mm has expert center sharpness throughout the range; indeed, it is sharper at 105mm broad-open than the Zeiss is at 70mm

Conclusion

It might not have the Zeiss badge, but the Sony E PZ 18-105mm F4 G OSS has good center sharpness throughout the whole zoom range, and that includes the initial aperture where zooms similar this are ordinarily poor, and especially then at the longer end of the range. The downside is that it'southward not too corrected in other areas every bit the Sony Zeiss E 16-70mm F4 ZA OSS, with which information technology is often compared. Information technology however wouldn't be an piece of cake choice, even taking into account the $400 premium for the Zeiss. However the longer reach of the Sony is attractive, and for video users especially, the ability zoom option may just swing it.
