Sony FE 85 mm f/1.4 GM: is it the right portrait lens?
A review of Sony's legendary portrait lens. Is the 85 mm GM still the best choice against the competition? A hands-on perspective.
If you've ever wondered whether the Sony FE 85 mm f/1.4 GM is worth the investment, you're in the right place. After years of use, I sum up what this lens can do, where it falls short and whether it's still the king of its category.
Optical quality and bokeh
The first thing that will win you over is its ability to separate the subject from the background. Wide open at f/1.4, the background blur is so strong and smooth that the background turns into an almost abstract canvas against which the main subject stands out.
Image quality is excellent, although I noticed a slight drop in corner sharpness wide open. That's normal for lenses this fast. Just stop down one or two stops (to f/2 or f/2.8) and the lens renders detail very sharply.
The bokeh is soft, creamy and free of the distracting rings or double edges that sometimes plague cheaper lenses. Colors are accurate and contrasty, which is key for portraits.
Autofocus for portraits
Autofocus is crucial these days, especially when you shoot moving subjects – kids, models walking or athletes. At f/1.4 the depth of field is very shallow: the model only has to turn slightly and the lens must refocus quickly and accurately. The GM handles this reliably.
It isn't perfect, though. In very low light or low contrast, focus can “hunt.” In that case, it helps to focus on a higher-contrast spot or fine-tune focus manually. For static portraits in the studio and outdoors, reliability is high.
Compared with the Sigma 85 mm f/1.4 Art
When you're looking for the best portrait lens, you can't ignore the Sigma 85 mm f/1.4 Art. It's a direct competitor with similar optical quality at a lower price.
- Sigma may be a hair sharper in the corners wide open, but the difference is minimal.
- Sony GM wins on ergonomics and integration with the camera body; it's well balanced on Alpha bodies.
Practical use
In practice, the 85 mm GM is ideal for portraits both outdoors and in the studio. It's compact enough to keep with you all the time, and good enough that it won't hold you back.
The f/1.4 aperture lets you shoot in lower light too, but for the best results I recommend f/2 to f/2.8. At f/1.4 you have to watch the depth of field – when the model is turned, only one eye may be sharp and the other already blurred.
Conclusion
The Sony FE 85 mm f/1.4 GM is a great lens that deserves a place in every portrait photographer's kit. It offers excellent optical quality, reliable autofocus and beautiful bokeh. There are cheaper alternatives, such as the Sigma Art, but the Sony GM offers better integration with the Sony ecosystem. If you have the budget and want the best for portraits, it's an investment that pays off.
