Between the Z 8 and α1 II, the Z 8 comes out ahead in several specs, while the α1 II wins on weight and af points. Overall, the Z 8 scores 61.1 and the α1 II scores 64.4 on our Mars Score.
Which should you buy?
The α1 II edges ahead on the Mars Score (61.1 vs 64.4), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The Z 8 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 α1 II if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, af points, megapixels.
Both ship with comparable sensor size, max video, in-body 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.
