PZ OSS SELP1. 65. Review. SLRgear Review. June 5, 2. 01. 3by William Brawley. ![]() If we go back a few years, we see Sony executives outlining a strategy of "more." It started in Sony Semiconductor for sensors, but was quickly echoed by the Sony.The Sony E 1. 6- 5. PZ OSS is an E- mount zoom lens that's frequently bundled as a kit lens with several Sony NEX- series compact system cameras such as the NEX- 6. Designed for APS- C sensors, the lens features a field of view range equivalent to a 2. This lens isn't a ''constant'' lens, in that as you increase the focal length, both the maximum and minimum aperture sizes decrease. The following table reflects the aperture changes as you zoom: Focal length. Max. apertureƒ/3. Min. apertureƒ/2. The lens features built- in electronic optical image stabilization, as well as a new electronic zooming mechanism controlled using a "wide- to- tele" toggle switch reminiscent of a camcorder's zoom button. The Sony lens also features a single rotating ring that functions either as a traditional zoom ring or as a focusing ring depending on the shooting mode of the camera. Both focusing and zooming on this lens are electronically controlled. Image stabilization is controlled via the camera as well. The lens is not compatible with a lens hood, but does accept 4. Sharpness. At 1. 6mm and f/3. Sony E 1. 6- 5. 0mm f/3. PZ OSS is fairly soft in the corners and across much of the frame, but the very center of the frame remains fairly sharp. As you stop down, f/5. Zoomed in to 3. 5mm, overall sharpness improves, and at f/8, the corners start to look pretty good, although still not tack sharp. At 5. 0mm, you'll see the best results at f/8. Based on the numbers, the best results overall are at 3. Strangely, at 1. 6mm at f/8, we saw the largest difference between sharpness at the center vs. The center of the frame was quite sharp, but the corners, conversely, were very soft. This is unusual in our experience; normally sharpness becomes more uniform across the frame as you stop down. At all focal lengths, once you stop down to f/1. Chromatic Aberration. Chromatic Aberration appears very well- controlled on the Sony 1. At both 3. 5mm and 5. CA in the extreme corners of frame vs. We do see more CA in the corners at the 1. CA is still quite low for a wide- angle zoom lens. CA is however suppressed by the camera body by default in JPEGs, and during RAW conversion via an embedded lens profile which cannot be disabled in Adobe Camera Raw. Shading (''Vignetting'') Wide open at 1. Sony lens suffers from pretty severe vignetting, with the corners being more than 1- stop darker than the center of the frame. At f/1. 6- 2. 2, we still saw light loss in the corners, at just shy of 0. At 3. 5mm and 5. 0mm, vignetting levels are almost identical, with less than a half- stop of light loss in the corners at f/5. At all focal lengths, as the aperture is stopped down, vignetting decreases. Distortion. Lens design is a juggling act, and optical engineers have to decide how to trade off between sharpness, CA, shading (“vignetting”) and distortion. The ability to correct for some of these shortcomings in the camera, post- capture means that lens designers can allow some parameters to drift, and in the process achieve better results in the other areas. This is common practice for Micro Four Thirds lenses, but the Sony 1. E- mount lens, however it probably won't be the last. The uncorrected RAW files show really dramatic amounts of geometric distortion, that's corrected- out by the NEX cameras in their in- camera JPEGs. At the wide end, we see truly dramatic distortion, with no less than 3. It's literally off our charts. The average amount of distortion over the entire frame is just over 1. As noted, the in- camera JPEG processing does a significant amount of distortion correction, producing almost perfectly- corrected images. If you shoot RAW photos, though, you'll see a big difference between those compared to straight- from- the- camera JPEGs, unless your RAW converter applies a lens profile to correct it automatically. There is not an option to turn off this in- camera correction for JPEGs, at least on any current Sony NEX bodies. Once you zoom to 3. At 5. 0mm, the average distortion across the entire frame is very close to zero, while there is a bit of pincushion distortion (less than 0. Autofocus Operation The Sony 1. PZ OSS lens can focus very quickly - - it only takes about a second to go through the full range from minimum focus distance to infinity. When shooting with this lens, autofocus felt very fast, quick and it locked onto targets easily. Macro. This lens isn't specifically built for macro, with maximum magnification of 0. Build Quality and Handling The E 1. PZ OSS lens is quite small and compact at just 1. When the camera is powered on, the lens automatically extends to nearly double its length. It fits nicely on a Sony NEX- 6, feels nicely balanced, and is fairly compact, particularly when powered off. It's not heavy or bulky at all. When stored away, this lens and camera combo could easily be put in small bag, cargo pants pockets or a large coat pocket. If you carried the two separately, though, they could easily fit in regular pants pockets.)The exterior of the lens is plastic with a smooth, glossy black finish. The lens mount is metal, as is the single dual- function zoom/focus ring. The only button or switch on the lens is the powerzoom slider switch on the left side (think 7 to 9 o'clock position). There are no focal lengths marked, nor is there a manual focusing/depth of field scale. Inside the barrel sit 9 lens elements in 8 groups, with one ED and four aspherical elements. The aperture mechanism has 7 blades for a fairly circular aperture. The zoom/focusing ring is about 3/8th inch wide and has an array of small ribs for texture. Very little force is necessary to turn the ring; it's easy to rotate with one finger. The zoom/focus action is very smooth, and rotates indefinitely, as zooming and focusing are electronically controlled. While focusing or zooming, the front element of the lens doesn't rotate, so filters such as circular polarizers work fine. The lens does extend during zooming, though, about 1/4th of an inch. The Sony 1. 6- 5. Sony's Optical Steady. Shot image stabilization technology, which worked quite well. See our IS Test tab for more details on this. ALTERNATIVESThere are very few other options for E- mount lenses, particularly those that feature similar specs to the Sony 1. There is the Tamron 1. Di III VC, which provides a similar wide- angle focal length, but offers a much higher telephoto range (as well as size, weight and price). It also features image stabilization technology. The other option would be to forgo the zoom lens, and buy a set of prime lenses. Sigma makes a set of E- mount prime lenses: 1. Carl Zeiss Touit series of primes: 1. These would allow you to have a similar range of focal lengths with much wider apertures, but at the expense of more lenses to carry and a much higher price. CONCLUSIONThe Sony E 1. PZ OSS is a compact and inexpensive kit zoom lens that produces decent results, although it suffers from heavy barrel distortion at wide angles and produces images that are only super- sharp at the center. That said, it does better than most kit lenses, to the point that you may not feel the need to immediately rip it off and replace it with something better. It's a very serviceable shooter. The big selling points here are its compactness as well as the powerzoom and image stabilization features, both of which come in handy for video shooting. Product Photos. Sample Photos. The VFA target should give you a good idea of sharpness in the center and corners, as well as some idea of the extent of barrel or pincushion distortion and chromatic aberration, while the Still Life subject may help in judging contrast and color. We shoot both images using the default JPEG settings and manual white balance of our test bodies, so the images should be quite consistent from lens to lens. As appropriate, we shoot these with both full- frame and sub- frame bodies, at a range of focal lengths, and at both maximum aperture and ƒ/8. For the ''VFA'' target (the viewfinder accuracy target from Imaging Resource), we also provide sample crops from the center and upper- left corner of each shot, so you can quickly get a sense of relative sharpness, without having to download and inspect the full- res images.
