So they salvage a 20-27mm range but lose a f2.7-f3.4 range 2/3rds of a stop!). A Canon/Sony 16-35mm f2.8 also is faster, goes wider, but it lacks the 35-50mm range. Tokina's 14-20mm f2 is a 21-30mm f3 lens, half a stop faster but quite a bit shorter.

So, yes, it is novel a range. And perhaps attractive for MFT users, if the price is not too crazy.

No, they don’t lose 2/3 of a stop. It is an F/1.7 lens, so slightly faster.

If you want to talk equivalence, please say so. It is not the same, however.

Kind regards, Wim
Gear: Canon EOS R with 3 primes and 1 zoom, 4 EF-R adapters, Canon EOS 5 (analog), 9 Canon EF primes, a lone Canon EF zoom, 2 extenders, 2 converters, tubes; Olympus OM-D 1 Mk II & Pen F with 12 primes, 6 zooms, and 3 Metabones EF-MFT adapters ....
