Have you ordered the Sony 20mm F1.8 G?Id miss the 24-27 range. Was happy to sacrifice it on the 28-200 but i definitely miss it.
I think these 28+ lenses suite people that prefer the longer end of that range, when i had a 24-70 the majority of my shots are at the wide end.
My absolute ultimate lens would be something like a 20-60 or there abouts. Really looking forward to my 20mm coming, being limited to 28mm widest for too long now.
