Sony FE 50mm F1.2 GM

The Sony Carl Zeiss Sonnar T✻ FE 55mm F1.8 has been my trusted lens for nearly two years, since March 2022. Its performance has consistently delivered outstanding and sharp images. The rendering of a portrait and the environment is just pleasing as attested by the photos below.

An aperture of f/1.8 offers a significant opening, but after delving into reviews and watching various YouTube videos, it became evident that f/1.4 (or even better, f/1.2) brings about a distinctive experience. Having used the Sony FE 35mm F1.4 GM for nearly a year, I can attest that it has become my favourite lens. The f/1.4 aperture not only provides speed but also yields a beautiful bokeh effect in the background.

In December 2023, during my visit to Malaysia, I took the Sony FE 24mm F2.8 G, the Sony FE 24-70mm F2.8 GM, and the Sony Carl Zeiss Sonnar T✻ FE 55mm F1.8. At a wedding reception, the 24-70mm lens proved versatile, but I frequently extended it to 70mm at f/2.8 to get the bokeh effect. On another wedding reception, the 55mm lens delivered pleasing results, though I desired a slightly more pronounced softening of the background.

On leaving Malaysia, I was thinking of upgrading to a dedicated 50mm GM lens, initially considering f/1.4 as the ideal choice. However, in January 2024, I came across one boasting a maximum aperture of f/1.2. Several factors influenced my choice, including the obvious appeal of the wider aperture and the presence of a physical aperture ring on the lens body. Notably, after reading multiple reviews, it became apparent that the F1.2 GM surpasses the F1.4 GM and even the 55mm F1.8 Zeiss in performance. (Some reviewers did suggest sticking with the 55mm F1.8 Zeiss if already in possession.)

But the main reason for the upgrade is that I’ve become accustomed to the physical aperture ring on the lens body, which enables swift adjustments to get the desired aperture. However, with the 55mm lens, the process of manually scrolling on the camera took some time, especially when returning to the previous aperture position. In addition, there are two additional keywords: bokeh rendition and overall sharpness.

Here are some tests I conducted within a week of acquiring it. From what I can see, this definitely is a very specific lens! One word comes to mind: overkill 😅🤨

My first after one week impression: I’ve been using the 55mm lens for nearly two years, and I genuinely appreciate the quality of the photos it produces. Recently, I made the decision to “upgrade” to the overkill 50mm F1.2 GM lens, and its f/1.2 aperture is truly magical. However, I’m not ready to part ways with the 55mm just yet. The 50mm F1.2, albeit FANTASTIC, comes with an overkill weight too, making it less practical for casual outings. Therefore, I’ll still be holding onto my trusty 55mm for those lighter, more spontaneous photography moments. My only complaint is that the filter thread is just odd. Why not align it with other GM lenses at 67mm or 82mm?
