The Sony A7 IV is a do-everything full-frame body, and the lens you pair with it decides whether it leans toward stills, video, or a bit of both. We compared native G Master and G optics against strong third-party options from Tamron and Sigma, weighing sharpness, autofocus, stabilization behavior, and how each balances on the camera.
Every pick below resolves the 33-megapixel sensor cleanly and tracks reliably with the A7 IV autofocus. The right choice comes down to your subject, your budget, and how much weight you are willing to carry.

Detailed Reviews and Top Picks
1. Sony FE 24-70mm f/2.8 GM II
91/100
Best Overall
Key spec: Full-frame E-mount standard zoom, constant f/2.8.
This is the lens most A7 IV owners end up wanting, because it covers the everyday range with G Master sharpness and gives up almost nothing wide open. Autofocus is fast and silent, and Sony trimmed enough weight that it no longer feels front-heavy on the body. The obvious catch is that it sits at the top of the range, so if you mostly shoot in good light or on a budget, a slower zoom will stretch further for you.
- Reference-grade sharpness across the frame
- Fast, quiet dual XD linear autofocus
- Noticeably lighter than the first version
Pros
- Outstanding corner-to-corner detail
- Excellent for both stills and video
- Compact for a pro standard zoom
Cons
- The most demanding pick on your budget
2. Tamron 28-75mm f/2.8 Di III VXD G2
86/100
Best Value Zoom
Key spec: Full-frame E-mount standard zoom, constant f/2.8.
If the GM II is more lens than you need, this Tamron delivers most of the image quality for a fraction of the commitment. The VXD motor is quick enough for events and everyday work, and the light weight makes it an easy walk-around choice. You give up a little at the wide end, so photographers who shoot tight interiors or sweeping landscapes may miss those extra few millimeters.
- Close to GM sharpness for far less outlay
- Quick VXD linear focus motor
- Light and travel-friendly
Pros
- Strong value for a constant f/2.8 zoom
- Genuinely sharp by the center and mid-frame
- Handy close-focus at the wide end
Cons
- Starts at 28mm, not 24mm
- Build feels less premium than native glass
3. Sony FE 70-200mm f/4 Macro G OSS II
85/100
Best Telephoto
Key spec: Full-frame E-mount telephoto zoom, constant f/4, optical stabilization.
For reach without a heavy bag, this updated 70-200mm is a standout, adding close-focus macro that makes it far more flexible than the spec sheet suggests. Paired with the A7 IV stabilization, handheld shots at slower speeds hold up well. The trade is the f/4 aperture, so if you shoot dim gyms or want the creamiest subject separation, a faster telephoto is worth the extra bulk.
- Sharp through the whole zoom range
- Half life-size macro at both ends
- Compact and light for a 70-200mm
Pros
- Versatile reach for portraits and details
- Effective stabilization pairs with in-body IS
- Much lighter than an f/2.8 telephoto
Cons
- f/4 limits low-light and background blur
- Not the pick for indoor sports
4. Sony FE 85mm f/1.8
83/100
Best Portrait
Key spec: Full-frame E-mount short telephoto prime, f/1.8.
This 85mm is the easiest way to get classic portrait rendering out of the A7 IV without spending on a GM prime. Skin tones and background falloff look lovely, and it stays light enough that you will actually bring it along. You may spot a little color fringing on high-contrast edges wide open, so pixel-peepers who want flawless output at f/1.8 should look at the pricier GM alternative.
- Flattering portrait perspective
- Smooth, rounded background blur
- Light enough to carry all day
Pros
- Excellent value for a portrait prime
- Sharp wide open where it counts
- Fast, confident autofocus on faces and eyes
Cons
- Some longitudinal color fringing wide open
- No optical stabilization
5. Sony FE 35mm f/1.8
79/100
Best for Street
Key spec: Full-frame E-mount wide prime, f/1.8.
A 35mm prime is the natural single-lens companion for the A7 IV, and this one is compact, quick to focus, and bright enough for evenings out. It is the lens to grab when you want to travel light and stay unobtrusive. Landscape shooters who scrutinize the extreme corners at f/1.8 will notice some softening, though stopping down cleans it up quickly.
- Versatile 35mm field of view
- Compact and discreet
- Quick, near-silent focus
Pros
- Great everyday and travel focal length
- Small footprint suits candid shooting
- Solid low-light capability
Cons
- Corners soften slightly wide open
- Not weather-sealed to pro standards
6. Sigma 24-70mm f/2.8 DG DN Art II
76/100
Best for Video
Key spec: Full-frame E-mount standard zoom, constant f/2.8.
Sigma packs a lot of glass and control into this Art zoom, making it a favorite for hybrid shooters who value a clicked or de-clicked aperture and confident sharpness. On the A7 IV it makes a capable one-lens rig for run-and-gun work. It is on the heavier side, however, so if compactness matters more than the handling extras, the lighter native option will suit you better.
- Robust, high-detail optics
- Smooth manual focus and aperture ring
- Well suited to hybrid shooters
Pros
- Excellent sharpness for the outlay
- Handling features aimed at video
- Solid weather sealing
Cons
- Heavier than the native GM II
- Focus breathing more visible than premium rivals
Frequently Asked Questions
For most owners the Sony FE 24-70mm f/2.8 GM II is the best single lens, covering wide to short telephoto with reference-grade sharpness. If you want most of that quality for less, the Tamron 28-75mm f/2.8 G2 is the value choice.
Yes. Current Tamron and Sigma lenses use fast linear motors and support the A7 IV eye and subject tracking reliably. They are a sensible way to build a kit without buying only first-party glass.
f/4 is plenty for daylight, travel, and general telephoto use, and it keeps lenses lighter. Choose f/2.8 if you regularly shoot indoor events or want the strongest background separation.
The Sony FE 85mm f/1.8 gives flattering perspective and smooth background blur at a friendly price. For flawless edges wide open, the G Master 85mm is the step up.
