These two lenses share the same focal length and maximum aperture, so the real choice is the camera system you shoot with. Both are fast 135mm primes for full frame mirrorless bodies, built for portraits, events and any scene where you want a tight view and strong subject separation. Specs such as weight and minimum focus distance differ, so confirm them on each maker’s page.
What Each Lens Is For
A 135mm lens on a full frame body gives a narrow angle of view and a compressed look. Faces stay flattering, backgrounds look larger behind the subject, and you can work from a comfortable distance. An aperture of f/1.8 lets in a lot of light and produces a shallow depth of field.
- Sony FE 135mm f/1.8 GM: an E-mount lens from Sony’s G Master line, aimed at working portrait and wedding shooters who want sharp detail and smooth blur.
- Nikon Z 135mm f/1.8 S Plena: a Z-mount lens from Nikon’s S-Line. The Plena name signals a focus on rich, even out-of-focus rendering.

Because the headline traits match, small points decide the outcome: how the lens balances on your body, how its blur looks to your eye, and how its autofocus behaves with your camera’s subject tracking.
How to Decide
- Begin with your body. Native lenses work best on their own system. Adapting across mounts is possible in some cases but adds bulk and can limit features.
- Look at sample images. Judge background blur, edge rendering and color on files shot by working photographers, not just charts.
- Check handling. Hold both if you can. A long fast prime feels different on a small body than on a large one.
- Think about your subjects. For fast action such as dance or sports, autofocus tracking matters more than blur character.
- Read the maker’s page. Confirm weight, close-focus distance, weather sealing and filter size before you commit.
Shooting Tips for a 135mm Prime
These are general baseline settings, not fixed rules. For portraits, try f/2 to f/2.8 when you want both eyes sharp. Keep a shutter speed of roughly 1/250 or faster for handheld work, since a long lens magnifies small movements. Leave room between subject and background to get the most blur, and use a lens hood to protect contrast in backlit scenes.
FAQ
Can I use the Sony lens on a Nikon body?
Not directly. The two use different mounts, and the flange distances and electronics are not compatible without an adapter. Adapters exist for some pairings, but they may limit autofocus, so check compatibility first.
Is 135mm too long for indoor portraits?
It can be in small rooms, since you need enough distance to frame a person. In a large studio, hall or venue it works well and gives a flattering, compressed look.
The Short Version
These lenses aim at the same job, so choose the one that belongs to your camera system. If you shoot Sony, the FE 135mm f/1.8 GM is the natural match. If you shoot Nikon Z, the Plena is the one to choose. Confirm exact specs on each maker’s page.
