Hi Andrew et.al, 

Hmm, given the responses so far it seems that Leica glass must only flare in 
Oz :-) 

I have experienced some surprising flare using my 35 ASPH Summilux (sans 
filters & with standard hood fitted) where my I am sure that my CZ35f1.4 + 
hood would have had no problems whatsoever. The worst thing about using 
an RF is that you don't find out until it's too late :-(
