Sony FE 90mm F2.8 Macro G OSS Review and Results

Sony FE 90mm F2.8 Macro G OSS Review and Results

By Jean Rydberg

Sony has dominated the full frame mirrorless market in recent years with the exceptional autofocus system and high resolution sensors of their Alpha line. And if you’re a macro shooter with a Sony Alpha camera, the best choice is the Sony FE 90mm F2.8 Macro G OSS lens.

The FE 90mm F2.8 was released in 2015 and quickly became a favorite of Sony shooters around the world. It features 1:1 magnification and a respectable minimum focusing distance of 11.02” (0.28m).

This review covers the lens build, specifications, and performance underwater. We've included examples from a wide variety of Sony E-mount mirrorless cameras including crop sensor compact mirrorless and professional full frame mirrorless.

Physical Appearance

As you would expect from a G Master lens, the build quality is solid. The lens is weather sealed making it dust and moisture resistant - though of course not waterproof outside of the housing! The exterior of the lens is plastic which helps to keep the weight down to 1.33 lb (602g). The lens is 5.14” (131mm) in overall length and 3.11” (79mm) diameter with a 62mm filter thread on the front. 

There are two switches on the side of the lens: Optical Steady Shot ON/OFF and a Focus Limiter switch. Typically we recommend leaving OSS ON and the Focus Limiter set to FULL.

Image Stabilization

Sony’s built-in Optical SteadyShot (OSS) system works well providing up to 3-4 extra stops of image stabilization. This particular helps us underwater where we float in the water column in addition to hand-holding the camera. 

The lens is exceptionally sharp. It pairs amazingly well with the Sony A7R Iv, which boasts the highest resolution of any full frame camera at 61 MP. We were able to capture images with the Sony A7R IV and 90mm macro that seemed to embellish almost microscopic detail that could be cropped to any heart's desire.

Focus

The focus motor is exceptionally smooth and quiet. The focus drive is completely internal and the lens does not extend or retract as you focus at different distances. Internal focus lenses are slightly more enjoyable to shoot and provide more consistent results when using external diopters on the front of your lens port.

The 90mm has a working aperture range from f/2.8 to f/22. While we rarely desire to go beyond those limits it could be a deal breaker for super macro photographers. The exceptional Canon 100mm f/2.8L Macro lenses (both EF and RF) have a working range down to f/32.

The focus ring on the lens moves forward and backward to switch between autofocus and manual focus. This is worth bearing in mind when installing it in an underwater housing.

Manual Focus

We prefer leaving the lens set to autofocus and using back button focus via the camera’s AF-ON button to shoot a hybrid auto-manual technique. The autofocus is particularly fast and accurate when shooting with a newer a7-series camera. Sony’s subject tracking autofocus is among the best on the market and can be a huge advantage when shooting fast moving fish and behavior shots.

If you want to go full manual focus, this is possible in DL system housings by adding the optional Manual Focus Gear # 5509.47.

Conclusion

The Sony FE 90mm f/2.8 Macro G OSS lens retails around $1,098 here in the USA and is well worth it if you want to focus on the small stuff underwater. It’s our top macro lens if you’re shooting a full frame Sony mirrorless camera. 

The 90mm will absolutely be a great investment in your underwater photography. However if you’re shooting a crop sensor camera like the Sony a6400 or a6700, a shorter focal length can be an easier entry point. You may consider the Sony FE 50mm f/2.8 Macro instead which is smaller, lighter, and about half the price.
