All scopes are excellent. We have compared all scopes. There are small differences between them.
For low light conditions Polar T96 and Zeiss V8 offered more than others - they have better light transmission.
Schmidt & Bender 4-16x56 Polar T96https://www.optics-trade.eu/ca/schmidt- ... r-t96.html
S&B Polar is especially designed for low light hunting and has a slightly higher light transmission as Zeiss V8.
Zeiss Victory V8 2.8-20x56 T*https://www.optics-trade.eu/ca/riflesco ... x56-t.html
Zeiss V8 is more versatile in his use, has a slightly larger field of view and a really small and fine adjustable red dot.
Swarovski Z8i 2.3-18x56 Phttps://www.optics-trade.eu/ca/swarovsk ... x56-p.html
Swarovski Z8i has among the all three the lowest light transmission but it has the larger field of view and is sharpest at the edges.
In case that you are looking for rifle scope just for evening/night hunting we would suggest the S&B Polar T96. If you are looking for a more versatile rifle scope then we would advise choosing Zeiss V8 or Swarovski Z8i.
