What makes the Sony FE 24-105mm f/4 G OSS special?
The 24-105mm range is one of the most practical zoom ranges you can put on a mirrorless camera. Starting wide enough for landscapes and architecture at 24mm and reaching 105mm for portraits and compressed travel shots, it genuinely replaces multiple primes for everyday shooting. The constant f/4 aperture means your exposure settings stay predictable no matter where you are in the zoom range — something you don't get from variable-aperture kit lenses.
The built-in OSS (Optical SteadyShot) works alongside the in-body stabilisation found in Sony bodies like the Sony Alpha 7 IV or Sony Alpha 7R V, giving you a serious hand-holding advantage in low light. The 9-blade rounded aperture produces smooth, pleasing bokeh at 105mm even at f/4 — not the razor-thin subject separation of a fast prime, but definitely usable for portraits. Close-up capability at 0.38m minimum focus distance also means you can fill the frame with flowers, food, or small objects without switching lenses.
Compared to the Sony FE 24-70mm f/2.8 GM, you trade two stops of light for an extra 35mm of reach and noticeably less weight. For travel and documentary work, that trade-off often makes sense. Against the Tamron 28-75mm f/2.8 G2, the Sony gives you a wider start (24mm vs 28mm), longer reach (105mm vs 75mm), and the convenience of OSS — while the Tamron wins on maximum aperture. The Sony FE 20-70mm f/4 G overlaps at the wide end and goes wider, but tops out at 70mm, so it's a different tool for a different job. If you shoot Sony and want one lens to cover almost everything, the 24-105 G OSS is the benchmark other lenses get compared against.
Who is the Sony FE 24-105mm f/4 G OSS for?
This lens is genuinely for anyone who wants to keep one lens on their camera most of the time. Here's how it maps to specific shooting styles:
- Travel photographers: One lens from wide landscapes to compressed street scenes
- Documentary and street shooters: Flexible reach, lightweight, and OSS for steady handheld work
- Videographers: Constant aperture, silent autofocus, and stabilisation for smooth footage
- Event photographers: Covers wide group shots to tight portraits without lens swaps
