Sony A6400 Lenses: Which Lens Fits

I would start with the Tamron 17–70mm f/2.8 when one lens should carry the day. The aperture stays at f/2.8 even at 70mm, and there is a stabilizer in the lens. Tamron calls it VC. The camera gets heavier at the front than the body itself. If that is too much, the Sigma 18–50mm f/2.8 sits better: clearly lighter, and without that stabilizer. In the evening you shorten the shutter speed instead of relying on the lens.

For faces at a normal distance I take the Sony E 35mm f/1.8. That is a prime: you do not zoom, you take a step. The stabilizer sits in the lens. Sony calls it OSS. I add the Sigma 56mm f/1.4 only once a portrait is its own appointment and you can step back a few paces.

Four lenses

17–70, 18–50, 35mm and 56mm for the A6400

The four cards are the shortlist, not a basket. For most days one of them is enough. What they cost today is on Amazon.

The A6400 has an APS-C sensor. It is larger than a phone sensor and smaller than full frame. Whatever you mount looks tighter because of that. Multiply the millimeters on the lens by about 1.5 if you want to compare them with a full-frame focal length. 35mm here is not a wide angle. It is roughly a normal view.

What it does not have is a stabilizer in the body. Sony often labels the version in the lens OSS. Tamron calls theirs VC. Both mean the lens cancels small movements and the camera does not. You notice it in a flat in the evening, in a church, on a short handheld clip. With a dark kit zoom and without that help you need a shorter shutter speed or a higher sensitivity. That sensitivity is called ISO. Turn it up and the picture gets grainier.

The viewfinder changes the second question. On the ZV-E10 an 11mm lens is often the point, because you hold the camera at arm’s length and film yourself. On the A6400 you usually look through the viewfinder at other people, a street, a table. An extreme wide angle is the exception, not the first lens.

The green row is the usual case: one lens, often handheld. Below that it gets lighter, tighter, or it becomes a portrait lens. If none of the questions fits, stay with the Tamron, because the camera will not handle the shake for you.

The number on the lens is not the angle of view you know from a full-frame camera. On the A6400 everything looks tighter. The bars show the longest focal length, converted. The Tamron gets closest to a portrait without a lens change. The 35mm stays at a normal distance. The 56mm wants room.

Tamron 17–70mm f/2.8 with stabilization

This is the lens I would mount on an A6400 if only one may come along. The range covers the walk and the face at the table. The aperture stays at f/2.8 even when you go to 70mm. VC, the stabilizer in the lens, catches what the body cannot. What you pay for that is weight. About 525 g hangs on the front of a camera that is about 403 g with battery and card. It no longer fits a jacket pocket. In a small bag, next to a second battery, it is exactly the one lens that makes the camera make sense.

Start here

Tamron

Tamron 17–70mm f/2.8 VC

One zoom that steadies the A6400 for you

The A6400 has no stabilizer in the body. This zoom has one in the lens. Tamron calls it VC. On the A6400, 17 to 70mm looks roughly like 26 to 105mm on a full-frame camera: street, table, people, a light portrait, without changing lenses. f/2.8 stays constant, so the long end does not suddenly go dark. It weighs about 525 g. The camera with battery and card is about 403 g. The lens is heavier than the body. If you bought the A6400 because it is light, you will feel that in the bag. The price is on the Amazon page.

Sigma 18–50mm f/2.8, when it should stay light

The same idea, a shorter range, no stabilizer, clearly fewer grams. On the A6400 it looks about like 27 to 75mm. That is enough for a day in the city. In the evening you set the shutter to 1/80 of a second or shorter, instead of relying on a stabilizer. If you bought the A6400 because it is small and then hang on a zoom that is heavier than the camera, you talked yourself out of the lightness. Then the Sigma is the more honest lens.

Lighter

Sigma

Sigma 18–50mm f/2.8 DC DN

The same brightness, much less weight

Aperture stays at f/2.8 here too. The range is shorter: on the A6400, about 27 to 75mm. That covers a city day, family, the normal round. There is no stabilizer. In the evening, or when you film handheld, you shorten the shutter speed or you get steadier. In return it weighs about 290 g and stays balanced on the small camera. If the Tamron feels top-heavy in the hand, this is often the more honest lens. The price is on the Amazon page.

Was überzeugt

• +Bright and light on the small body
• +One lens for an ordinary day
• +Fits the same bag as the camera

Was Du wissen solltest

• −No stabilizer, and the A6400 has none either

Sony E 35mm f/1.8 with OSS

A prime. You do not zoom, you move. On the A6400, 35mm is roughly the view many people experience as normal, about 52mm in full-frame terms. OSS sits in the lens. f/1.8 is visibly brighter than f/2.8 in the evening. Autofocus is an older generation and can whirr on video. For stills through the viewfinder that is rarely a reason to leave it at home. It is the lens when you do not want a zoom decision and faces are the most common job.

Sony

Sony E 35mm f/1.8 OSS

A prime that steadies the shake itself

A prime does not zoom. You step forward or back. On the A6400, 35mm looks roughly like 52mm: the distance where faces stay natural. f/1.8 lets in more evening light than either zoom here. OSS means the stabilizer sits in the lens. That is exactly what the body lacks. Autofocus is an older generation and can be audible on video. For stills that rarely matters. The lens weighs about 154 g. The price is on the Amazon page.

Was überzeugt

• +Steadier in the hand than a zoom without stabilization
• +Brighter than f/2.8 when the light goes
• +Small enough that the A6400 stays a small camera

Sigma 56mm f/1.4 for portraits

About 84mm. You need a few steps of distance, or you crop the forehead or the nose looks too big. In return a face separates calmly from the background once you open the aperture. It has no stabilizer. For a portrait by the window, camera steady, person still, that does not matter. As the only lens for Saturday at the market, it is too tight.

Portrait

Sigma

Sigma 56mm f/1.4 DC DN

For portraits, once you can step back

On the A6400, 56mm looks roughly like 84mm. That is the distance where a face separates softly from the background without the nose looking too big. f/1.4 leaves very little in focus. You have to hit focus. The A6400’s autofocus helps. There is no stabilizer. For a posed portrait by a window, a short shutter speed is enough. For walking and filming, this is the wrong lens. The price is on the Amazon page.

• +Faces separate calmly from the background

The Sony E PZ 16–50mm is often already on a used camera. PZ means it zooms with a motor, not with your hand. It has OSS, it is small, and it goes dark at the long end, f/5.6. Keep it if it came along. Do not buy one extra if you are about to get one of the zooms above. It is the start, not the destination.

A Sony E 18–135mm OSS is the travel alternative when you want reach and can live with a darker aperture. The stabilizer is the reason then, not the blur. It does not replace the Tamron if you photograph people in the evening.

The Sony E 11mm f/1.8 is the ZV-E10 lens for an outstretched arm. On the A6400 you only need it if you film yourself. The screen flips up for that, straight into the accessory shoe. A microphone in the shoe then sits in the screen’s view. If you mostly talk in front of the lens, the ZV-E10 is often the more honest camera than a stills body whose viewfinder stays unused.

A Sony FE 50mm f/1.8 fits mechanically. FE means it was designed for a larger full-frame Sony. On the A6400 it acts like about 75mm and usually has no stabilizer. For portraits, the Sigma 56mm is the lens designed for this smaller sensor. Save the big full-frame lens for the day you actually switch. Until then you carry size the sensor does not use.
