## [Sony FE 50-150mm f/2 GM Review](https://opticallimits.com/sony/sony-fe-full-format/sony-fe-50-150mm-f-2-gm-review/)

_2026-08-17 · Klaus · OpticalLimits_

Decades ago, fast zoom lenses had a maximum aperture of f/4.

It appears that the manufacturers are now readying the next phase centered around f/2 lenses, thus almost matching \[...\] The post Sony FE 50-150mm f/2 GM Review appeared…

## [Sirui Aurora 85mm f/1.4 (Sony E-mount) Review](https://opticallimits.com/sony/sony-fe-full-format/sirui-aurora-85mm-f-1-4-sony-e-mount-review/)

_2026-08-11 · Klaus · OpticalLimits_

Sirui may not be a household name among photographers yet, but the company has been a player with the cinema lenses for more than a decade. They are well-known for the anamorphic cine lenses. However, they also released some more photography-centric AF lenses with their Aurora (full-format) and Sniper (APS-C) lineups. One of them is \[...\] The post Sirui Aurora 85mm f/1.4 (Sony E-mount) Review…

## [Sony FE 100mm f/2.8 macro GM OSS Review](https://opticallimits.com/sony/sony-fe-full-format/sony-fe-100mm-f-2-8-macro-gm-oss-review/)

_2026-08-07 · Klaus · OpticalLimits_

The FE 100mm f/2.8 macro GM OSS is Sony’s 2nd generation macro lens for the E-mount system. It supersedes the FE 90mm f/2.8 macro G OSS, which has been with us since 2015. Sony is convinced that they created something special here because they lifted the designation from G to GM class for the new \[...\] The post Sony FE 100mm f/2.8 macro GM OSS Review appeared first on OpticalLimits .

_2026-08-06 · Klaus · OpticalLimits_

Introduction After all these fancy new lenses for mirrorless cameras, let’s do a little excursion to a blast of the past – the not-yet-quite-vintage Nikkor AF-S 105mm f/1.4 E ED in Nikon F mount, released back in 2016.

_2026-08-05 · Klaus · OpticalLimits_

Introduction We tested the Viltrox AF 9mm f/2.8 Air (black version) in Sony E-mount a while ago already. For obvious reasons, we’ll reuse most of the findings of this test here again. The MTFs, vignetting, and CAs tests were run again, though. The 9mm f/2.8 Air XF is an APS-C format lens equivalent to about \[...\] The post Viltrox AF 9mm f/2.8 Air XF (Silver) Review appeared first on OpticalLimits…

Introduction This is a retest of the Viltrox AF 15mm f/1.7 Air XF – this time with a silver finish, which matches with the silver-top Fujifilm cameras a la X-T5 and the like. We’ll reuse most of the original review, but the MTF and CA tests were executed again with this sample.

Over the last few years, Canon has created a set of hybrid prime lenses that prioritize video features alongside still photography. These lenses share a nearly identical form factor, minimal focus breathing, a fast f/1.4 max aperture, and they use a magnetic VCM (Voice-Coil-Motor) with Nano USM to drive focus groups independently for autofocus.
