Nikon - NIKKOR Z 24-70mm f/2.8 S vs Tamron - 28-75mm f/2.8 Di III VXD G2

These two are nearly even on the Mars Score (55.3 vs 57.1). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

The NIKKOR Z 24-70mm f/2.8 S doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Pick the 28-75mm f/2.8 Di III VXD G2 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, min focal, max focal.

Both ship with comparable weather sealed, optical stabilization, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
