I use this Canon EOS 1200D only now and again, where conditions are calm and there is no chance of salt water getting on/in to it. The quality of picture goes without saying on SLR cameras and with RAW file, you almost can't go wrong. Worth while learning all the settings on this type of camera as there is so many things can go wrong if you are on the wrong setting.
Because this is not waterproof, constant care to keep it dry is essential, salt water quickly ruins the glass on a lens. I usually carry mine in a waterproof bag and then place that inside a deckbag. Even if not splashed with sea water the lens must be cleaned after a trip on the sea as the salt air is enough to ruin a lens. There is of course waterproof SLRs on the market but a lot more expensive than this camera which is at the lower price range for such cameras.
Care needs to be taken while packing inside the kayak, more fragile than action or compact cameras and much more susceptible to condensation. I often carry a tripod when carrying my SLR, useful for many situations especially as light begins to fade and exposure time need to be longer. When taking a picture where there is no action, I like to take several photographs at different settings and different angles and hope that at least on will be a good one. I am not a professional and still have much to learn about this camera. I have stupidly enough put this in a dry bag which I used on an earlier trip for carrying some small birch logs, resulting in a lot of dust on the inside. Self cleaning has helped but needs to be sent in to an authorized reparation center. I do like this camera, but it is not an action camera and for kayaking it is not the most practical.
