In this post, we compare the Sony 135mm f/1.8 lens with the Sony 85mm f/1.4. Both are good options for someone interested in a dedicated portrait lens, but each has specific pros that can make it better suited for specific shooting needs.

Sony 135mm f/1.8 lens vs 85mm f/1.4

Key Lens Differences

AF Speed

These are very similar lenses. However, there are two key difference makers that make a notable change in usage. The first is autofocus speed. The Sony 135mm f/1.8 has four linear motors while the 85mm f/1.4 only features two. The result is a marked difference in autofocus speed; as depicted in the video, the 135mm is significantly faster than the 85mm. This isn’t necessarily a deal breaker for the 85mm if you plan to use it specifically for portraits. However, if you plan on using it to take action shots it would behoove you to choose the 135mm.

Focus Settings

The other key difference is the number of focus hold buttons present on these lenses. For a little background, a focus hold button does exactly what it sounds like; when you have the level of focus you want, simply press this button and it will remain the same regardless of where you or your subject moves.

The Sony 135mm f/1.8 has two focus hold buttons strategically placed on its body while the 85mm has one. As a result, using this feature is a little bit easier when using the 135mm. Again, we wouldn’t classify this as a deal breaker if you don’t use (or intend to use) this feature. However, it’s definitely a nice option to have.

Conclusion

The Sony 135mm and 85mm lens are both great options for someone looking for a dedicated portrait lens. The Sony 135mm is priced at $1,898 and the 85mm at $1,798. But with that extra $100 you are getting newer technology.
