These two Tamron f/2.8 zooms for full frame mirrorless cameras do different jobs. The 17-28mm is an ultra-wide to wide zoom for landscapes, interiors and architecture, while the 28-75mm is a standard zoom for portraits, events and everyday shooting. If you can only choose one, the 28-75mm is the more general tool. We have not used these lenses ourselves, so confirm exact specs on Tamron’s pages.
What Each Lens Is For
The 17-28mm covers a wide view that fits large scenes and tight rooms. The 28-75mm spans from a modest wide angle to a short portrait length, which makes it a common one-lens choice for weddings, travel and family events. Both offer a constant f/2.8 aperture and a compact design for their class.
Key Differences
| Trait | 17-28mm f/2.8 | 28-75mm f/2.8 |
|---|---|---|
| Focal range | 17-28mm | 28-75mm |
| Best for | Landscapes, interiors, architecture | Portraits, events, travel |
| Aperture | Constant f/2.8 | Constant f/2.8 |
| Role in a kit | Wide specialist | General workhorse |
The 28mm end overlaps by design, so the two lenses fit together with no gap in coverage. Check the maker’s pages for versions, weights and filter sizes.
Choosing Between Them
- Choose the 17-28mm if you often feel that you cannot step back far enough, such as in small rooms, narrow streets or wide landscapes.
- Choose the 28-75mm if you photograph people, events or travel scenes and want one lens that handles most situations.
- Consider both if you want a compact two-lens kit that covers a wide span with the same aperture.
Kit Planning
A wide zoom and a standard zoom with the same aperture make exposure decisions easy, because you can swap lenses without changing your settings. They also share a similar look in color and contrast when made by the same maker, which helps when you edit a set of mixed images together. If you are building a kit over time, buy the lens you will use most first and add the second when a clear gap appears.
Practical Tips
- Think about your most used focal lengths. Look at your past photos in a catalog and see which range appears most.
- Keep the camera level with the 17-28mm to avoid leaning vertical lines.
- Use f/2.8 on the 28-75mm for portraits and low light, and close down to around f/5.6 to f/8 for sharper group shots and landscapes as a baseline.
- Match filter sizes if you plan to carry both lenses, so one set of filters works on each.
FAQ
Is 28-75mm enough for portraits?
Yes, for many situations. The 75mm end gives a flattering short portrait view, though dedicated longer lenses can offer more compression and blur.
Is 17mm too wide for general use?
It can feel wide for everyday scenes, and it stretches subjects near the frame edges. It excels when you need to fit a lot in the frame, but it is less natural for casual portraits.
The Short Version
Choose the 28-75mm as a first lens for a full frame mirrorless camera because it covers most daily needs. Add the 17-28mm when wide scenes and interiors become a regular part of your work.
