Busted by client for using Panasonic cameras

I was at a shoot yesterday with my biggest client. I was shooting their 2 new yachts and working with one of their marketing guys when I asked him if he could hand me my other camera from my bag. He handed it to me and said in a disappointed voice" I thought you shot with Nikon or Canon, you use Panasonic?". I said I do and asked him if he had a problem with any of the work I had done in the past. He said "No, the photos from the last shoot were awesome.". I said thanks and left it at that.

It was the first time I've ever been questioned about my gear by a client.
