I had to post to communicate how wonderful this lens is! I received it in the mail a few days ago and quickly compared it to my Batis 18, Batis 25mm lenses, my loxia 35mm(My loxia 21mm is currently in for repair) and the Sony16-35 F4. I can say that I will be selling my Batis 18, and Sony 16-35 F4. The New Sony 16-35 G series lens is sharper(Not by a ton) than all the wide angle primes I listed. I'll keep the Batis 25 f2 because it's faster and great for low light events and I'll keep the Loxia 35 and 21 because I like them for video and they are such well made lenses that it would be very hard to part with them. The 16-35GM will now by my main wide angle landscape lens.
