We are ALL waiting for the MTF tests of the GF 20-35, to verify if the optical quality is comparable (or better?) to the fixed lenses (in particular the GF 23 and GF 30) !!!
We hope that some independent company will soon examine this lens which, on paper, appears to be very good.
Meanwhile, it is known for sure that deliveries to stores will be delayed due to the shortage of electronic parts and the large number of reservations.
