I'm hoping to travel to Scotland, Ireland and Cornwall in March and wonder if there are any suggestions about traveling there with my K-3ii and accessories - airline restrictions for overseas flights (from the US). I've no idea what to expect with regards to the weather. An suggestions for minimum gear to travel with?

I have a camera back pack that is capable of containing my K3, batteries, lenses chargers and laptop. I also have a canvas messenger bag that collapses flat that goes in my luggage and can be used to carry the camera and selected lenses for the day’s shooting. I also have a Mephoto carbon fiber tripod that also can be converted to a monopod and folds up small enough to also go in the luggage. Most days I will only carry my 18-135mm and a 55mm F1.8 lens. The 55 mm lens works well in low light situations and with the camera turned sideways can be used to take several shots that can then be merged to make a wide angle image in churches and other low light places. Have a great trip and please share your results. I carry the backpack on the plane with a small rollaboard with some clean socks and underwear in case my checked luggage is lost. Do not plan to carry toiletries on the plane, they should go into your checked luggage.

Expect it to be above freezing, with temperatures between 40-50 F. Expect it to rain for some part of most days and that it will be cloudy much of the time. You can carry on several rechargeable K-3 camera batteries without any trouble. Your lens choices will be dictated by what you like to shoot. The water resistant kit lens comes in handy when it's raining. Bring some ziplock bags to put your gear in when going from cool to warm (outdoor to indoor) conditions to prevent lens fogging while gear warms up. Bring cotton towels to wipe off gear before putting it in the ziplock bags. If you want to use your non-water resistant lenses outdoors in the rain, consider purchasing some rain sleeves for use over the lens.

Bear in mind that the UK will be leaving Europe at about that time. My sources tell me that it may be moved to an offshore replica of the British Isles being built in the South China Sea. So check before you leave. If the Chinese have duplicated the original climate of the UK, you will need your weather-sealed K3-ii. Think cold and damp. And that's just the food.

I am a Londoner. The best affordable places to eat are often the pubs. If you asking about photographic equipment, bear in mind that the UK is still in monochrome. I would take my K3 + my 70mm f/2.4 Limited + my 28mm or 35mm + my 55-300mm zoom.
