Hello, I had posted a requst for views on flash for SB28 and SB22. for my N70.I am also considering Quantaray PZ1. On study I feel that the PZ1 flash is equivalent to Sunpack 4000AF. Is this true ? Any owners of Sunpack 4000AF and Quantaray PZ1 who would like to share there views ? thanks in advance for your mails cheers -Rahul
