Sony FE 100mm f/2.8 Macro GM OSS: One-minute review
Sony introduced its original FE 90mm f/2.8 Macro G OSS in 2015, shortly after unveiling the A7 full-frame mirrorless camera. While the FE 90mm has served as a reliable macro lens for Sony users, it has been the sole first-party option for over a decade. Thus, the announcement of the new FE 100mm f/2.8 Macro GM OSS in September last year generated significant excitement.
I had the opportunity to test this lens alongside a Sony A7R V, equipped with a 61MP full-frame sensor, allowing me to evaluate the sharpness and image quality of the new macro lens.
As a macro photography enthusiast, I was eager to see how the Sony FE 100mm f/2.8 Macro GM OSS performed. Priced at $1,498 / £1,399 / AU$2,599, it stands as one of the most expensive consumer full-frame macro lenses available, costing 70% more than its predecessor. But is it worth the investment for those already using the older model?
In short, casual shooters may find the older, more affordable version sufficient. However, for serious professionals using Sony systems, the FE 100mm f/2.8 Macro GM OSS justifies its price with outstanding image quality, robust stabilization, 1.4x magnification, and compatibility with teleconverters.
It’s undoubtedly the best Sony lens for macro photography enthusiasts, though it comes at a premium.
Sony FE 100mm f/2.8 Macro GM OSS: Price and availability
- Price: $1,499 / £1,399 / AU$2,599
- Includes ALC-SH173 lens hood and soft case
- Announced in September 2025
The Sony FE 100mm f/2.8 Macro GM OSS is priced at $1,499 / £1,399 / AU$2,599, succeeding the decade-old FE 90mm f/2.8 Macro G OSS, which is currently available for around $1,050 / £819. The new lens incorporates advanced technology and features, justifying its higher price point, which is approximately 70% more in the UK and 40% more in the US.
Is the extra cost justified? For casual photographers, likely not. However, for professionals, the enhancements in stabilization and image quality make it a worthwhile investment. It also competes strongly against the Canon RF 100mm F2.8L Macro IS USM, which has been available since April 2021.
For those on a budget, the original Sony FE 90mm f/2.8 Macro G OSS remains a viable option, alongside third-party alternatives like the Sigma 105mm f/2.8 Macro DG DN Art and Tamron 90mm f/2.8 Di III Macro VXD, which, while lacking optical stabilization, are more affordable for those entering macro photography.
