She took part of our overseas on-location shooting sessions a couple times in the past 2 years. I found out this attractive lady likes to sneak around behind our backs and shoot with an electronic viewfinder digital camera while we were working. I dispatched her a Nikon D40x DSLR with a professional grade super wide-angle zoom lens on a recent trip to Mindoro and Palawan (both are provinces of the Philippine), even though she is not a photographic assistant to me. Moreover, that camera body I gave her was just becoming available and right out of the box at that time. Yes, brand new stuff!
