Each to their own David. The Fuji gives that flexibility to go small but make changes in future if need be. Although I admit I sometimes like the discipline involved in only having one lens, it promotes creative thinking.
Size factor is very important to me. But a single focal length is seriously limiting, especially on the shorter end. High MP can make up for the longer end by cropping in up to a degree.
I think the Q series offers a lot, good IQ, IP-rated weather sealing, size, and they don't lose their financial value as fast as other cameras. I bought my Q2 two years ago and I paid more initially than most Q2s in the market as it has a one-year warranty and was literally like new. Today, if I send it to MPB for a £1000 loss , if I sell it privately, this can be lower. It is a 33% loss, for two years. If I had the Sony A7R V, possibly I would have lost a lot more.
Interesting colours for this ship but it does not seem to be military one where they use camouflage colouring for hull. It's difficult subject, first shot is like hidden image to find ship.
