The Nikon Z 24-70mm f/2.8 lets in about twice as much light as the f/4 version, while the f/4 is noticeably smaller and lighter. Choose the f/2.8 for low light, events and shallow depth of field. Choose the f/4 for travel, daily carry and good light. Always confirm exact specs on Nikon’s product pages.
What Each Lens Is For
Both lenses cover the same popular range, from a moderate wide angle to a short telephoto, and both belong to Nikon’s S-Line for Z mount. The f/2.8 is the larger, more demanding professional workhorse. The f/4 is a compact, walk-around zoom that folds down when not in use.
Key Differences
- Light gathering: A wider maximum aperture means one extra stop of light. That allows faster shutter speeds or lower ISO indoors.
- Background blur: At the same focal length and distance, f/2.8 separates a subject from the background more than f/4.
- Size and weight: The f/4 is far easier to pack and balances well on smaller bodies.
- Handling: The f/4 typically retracts to a short length for storage, then extends before shooting. The f/2.8 keeps a fixed length that is ready at once.
- Filters: The two lenses use different filter thread sizes, so adapters or new filters may be needed if you switch.
Choosing by Situation
- Weddings, events and dim venues: Choose the f/2.8. The extra stop helps keep shutter speeds high without pushing ISO too far.
- Portraits: The f/2.8 gives a softer background at the long end, though neither lens replaces a fast prime for that look.
- Landscapes and travel: Choose the f/4. You will usually shoot at f/8 or smaller anyway, so the extra light matters less than carrying less weight.
- Video: Either works. A smaller lens is easier to hold on a gimbal, while the faster lens helps in dim rooms.
Side by Side
| Trait | f/2.8 | f/4 |

| Best for | Low light, events | Travel, daily carry |
| Storage length | Fixed | Retracts |
Think About Your Body and Bag
A Z 5 or Z 6 series body feels natural with either lens, but the smaller f/4 keeps the whole kit light for long days. If you carry a second lens and a flash anyway, the extra weight of the f/2.8 may be fine. Imagine a full day of shooting with each setup. If you would leave the heavier one at home, it is not the right lens for you, no matter what the specs say.
FAQ
Is the extra stop of light worth it?
It depends on where you shoot. Indoors without flash, one stop can be the difference between a sharp frame and a blurred one. Outdoors in daylight, you may rarely use it.
Can I use either lens on a DX body?
Yes, Z mount full frame lenses fit Nikon’s DX mirrorless bodies. The view will be tighter because of the smaller sensor, so check the equivalent focal range.
The Short Version
Choose the Nikon Z 24-70mm f/2.8 if you shoot in dim places or want more background blur. Choose the f/4 if you value a compact kit and mostly shoot in good light. Both are strong standard zooms, so let size and light decide.
