![]() With no loud whirring you won’t be scaring away any insects because of the sudden noise, and it also makes the lens useful for shooting video. There are, in fact, two lens groups that focus, both being driven with a Direct Drive Super Sonic wave Motor (DDSSM). The two restricted modes certainly make autofocusing faster, and I would recommend using these as much as possible depending on what you are shooting. The full range, 0.5m-infinity and 0.27m-0.5m, are the available options, with the latter obviously restricting the lens to its macro mode. To reduce this time there are three different focus limiting positions, which you set via a switch on the side of the lens. Obviously with such a large focus range it can take some time for the lens to focus from the closest distance to infinity. It is useful when shooting in continuous AF mode. When the lens hits the focus point you want, simply hold this button to lock focus the lens will then remain locked until you let go of the button. The focus-lock switch on the side of the lens helps make focusing even more easy, and is located on the side of the barrel where most photographers rest their thumb. Simply pull the lens to switch to manual focus, then a slight turn will instantly switch the viewfinder to magnified view, making very accurate focus selections a speedy process. I found this particularly useful for shooting macro images when sometimes only a slight focus shift was needed. Interestingly, the lens has a push/pull auto/manual focus switch, making it a quick switch between auto and manual focus. The body of the lens has a smooth matt metal finish, with a knurled rubber focus ring at the front end of the lens. It is certainly good enough for photographing live insects. To get a 1:1 magnification, the lens needs to be at its minimum focus distance of 28cm, which gives a good working distance between the subject and the end of the lens. ![]() Internally, the lens is constructed of 15 elements in 11 groups, with nine rounded aperture blades. Personally, I don’t see the 79 x 130.5mm dimensions, or 602g weight, being an issue, and I had no problem handling or carrying the camera around with me for a whole day. Once again, Sony has produced what many will think is a fairly large lens for the Alpha 7 cameras. Sony FE 90mm f/2.8 Macro G OSS review – Build and handling Overall, the OSS (Optical Steady Shot) built in to the lens works well, adding a touch of reassurance when shooting handheld street or landscape images, and it can also help with macro shots. The shallow depth of field means that just a slight shift back or forth can change the focus plane. ![]() At very close distances the problem is the back-and-forth movement that stabilisation can’t correct. I even managed to shoot some macro images at this speed, although more through luck, careful technique and firing a short burst than through the image stabilisation itself. Optical image stabilisation is featured in the lens, allowing me to shoot as slow as 1/15sec when taking images of distant objects. However, with a Sony 85mm FE lens rumoured to be among the next batch of lenses, Alpha 7 users wanting a specialist portrait lens might prefer to wait a little longer. Combined with the 90mm focal length, this means that the optic could double up as a portrait lens. Sony’s lens has an f/2.8 maximum aperture, with a minimum setting of f/22. In this context, the Sony 90mm Macro lens follows in the footsteps of the highly regarded Tamron 90mm, Tokina 100mm and Sigma 105mm macro lenses – quite an illustrious group to be part of. It offers a good working distance between the subject and the end of the lens, and has a narrow enough field of view so that backgrounds can be fairly concentrated and blown nicely out of focus. The 90-105mm focal length is a sweet spot for macro photographers. Sony FE 90mm f/2.8 Macro G OSS review – Features Now that Sony has released the FE 90mm f/2.8 Macro G OSS lens all that has changed, with this premium optic providing Alpha 7 users a dedicated macro lens. Until now, for anyone interested in macro photography, Sony’s own LA-EA adapters for Alpha-mount lenses or third-party adapters were the only way they could shoot macro images. However, for those times when speed isn’t as much of an issue, such as when shooting landscape or macro images, the use of third-party lenses has been a boon to the system and an affordable solution for DSLR photographers using the new full-frame E-mount system. There are some limitations to using DSLR lenses, such as the need to use manual focus with third-party lenses. ![]() Of course, this facility equally applies to other compact system cameras, but thus far, Sony is the only company to offer a full-frame sensor. Thanks to the E mount’s short flange distance, Sony Alpha 7 cameras are able to use many lenses originally designed for DSLRs.
