Thank you! About the time I received your response, I was reading through the thread about this lens in this forum ( http://www.fuji-x-forum.com/topic/1138-xf-50-140-f28-zoom/ ) and found answers to both of my questions. True noob moment
It's a cracking lens - as good as Canon's 70-200L II without the bulk and weight. I know some Fuji users are small form-factor primes only but coming from FF DSLR, even the heftiest XF zooms are still of reasonable weight.
