Just as a friendly warning, there are 2 things to consider if you decide to buy one of these cameras. I own the TG-4 and never tried TG-5 but I assume it is pretty much the same thing.
1. TG-4 is a very convenient camera in usage. However, if you zoom in the pictures and look at the details and noise, this is basically iPhone quality. Even my old Canon S95 gives better resolution. So buying this camera with a housing makes no sense to me. I use TG-4 exclusively for snorkeling and shooting grand kids at the beach or swimming pool because it is small and handy.
2. Olympus RAW files are not read by LR versions up to LR5. So unless you already own LR6, you will have to edit your pics in the clumsy Olympus soft that comes with the camera or convert them into TIFFs. Which is OK but takes time and TIFFs are memory hogs. Buying LR6 only for the sake of processing Olympus files is economically insane ($142 for the full standalone version at Amazon or about $10 monthly for the subscription at Adobe).
