Whichever you end up picking will depend on personal preferences and shooting style.

Let’s see the reviews!

The BEST Sony a6400 Portrait Lens: Sigma 56mm f/1.4 DC DN

The is the best portrait lens for Sony a6400, hands down.

Let’s start with the obvious: it’s an incredibly fast lens. With a max aperture of f/1.4, it’s one of the only 3 lenses for Sony E-mount that open this wide. It will help you always get tack sharp portraits, and it’s great to shoot low-light portraits.

Speaking about sharpness, this Sigma lens has excellent sharpness; acceptable at f/1.4, but downright excellent from f/2.

My favorite thing about this lens is the wonderful bokeh it produces, thanks to its 9-blade design: smooth and creamy.

Any weak points? Of course, like any lens. There’s no image stabilization, and the a6400 doesn’t have built-in image stabilization, but the f/1.4 max aperture will make up for it in most cases. And finally it’s not weather-sealed, but I personally rarely shoot portraits under the rain.

The Best Luxury Portrait Lens for a6400: Sony Sonnar FE 55mm f/1.8

Won’t settle for anything less than best in class? Then the is your new portrait lens!

It has been rated as #7 best lens of all time by Dxomark, which is pretty much everything you need to know to understand it’s the best portrait lens you could get for your Sony a6400.

Image quality is nothing short of exceptional, the autofocus is fast and reliable, there are limited distortion & vignetting, and it’s weather-sealed. It’s also a full-frame lens, which means you won’t need to replace it if you switch to a full-frame Sony camera.

My main regret is that there’s no image stabilization, which could be a turn-off if you plan to shoot mostly in low-light conditions.

The Best a6400 Budget Portrait Lens: Sigma 30mm f/1.4 DC DN

After seeing the expensive Sonnar lens, time to check out the best budget option for a Sony a6400 portrait lens.

The is the same series at our #1 pick (the Sigma 56mm f/1.4 DC DN), but it comes at almost half the price!

It’s an incredibly fast lens, with a max aperture of f/1.4, scoring great all-around on all features. It’s a 30mm, which is close to a 50mm equivalent when mounted on the a6400. This is a shorter focal length than all other lenses in this review, but closest to the human eye.

The low price point comes with a few cons, namely the lack of image stabilization and the lack of weather-sealing. These are definitely not major flaws, and all in all the Sigma 30mm is an impressive lens that could undoubtedly be priced much higher.

Best Stabilized Portrait Lens for a6400: Sony E 50mm f/1.8 OSS

As you might have noticed, all lenses in this review lack one feature: image stabilization.

This is where the comes into play. With the built-in image stabilization, it’s the perfect portrait lens for the Sony a6400 which doesn’t have this feature.

For shooting portraits, i.e moving subjects, having image stabilization will help you have sharper photos, especially if you’re a beginner.

It’s also a lightweight & compact lens, very affordably priced. I’ve noticed images often come up soft on the edges with this lens, but for portrait where your subject is most likely not on the edges, it’s not a huge con.

The Best Telephoto Portrait Lens for a6400: Sony E 85mm f/1.8

Sony SEL-85F18 Portrait Lens Fixed Focal 85mm F1.8 Full Frame Suitable for A7, ZV-E10, A6000 and Nex Series, E-Mount Black

• Fast telephoto lens
• ED glass compensates for aberrations
• Circular aperture with nine blades for beautiful blur effects, minimum focus distance 0.8 m

And finally, the last best portrait lens Sony a6400 users should consider picking up: the Sony E 85mm f/1.8.

If you’re happy with a 50mm or 85mm focal length, the lenses above are better choices. But if you’re looking for a longer lens, this is my suggestion.

Mounted on the Sony a6400, it’s a 127mm equivalent, going in telephoto range. It will create portraits with more compression, and can also be a great choice if you’re shooting portraits from a distance, in weddings for example.

Overall a great lens, with even a neat additional feature: a physical focus-hold button on the lens.
