A necessary accessory if you want to update your EM1 Firmware. I bought one in the city and used it today to update my OMD E-M1. Worked slick.

I love that this camera is waterproof. That was my main reason for buying this product. I can - and have - made underwater videos of my kids in the swimming pool. I also love taking pictures of the sky from under water. The effect is very interesting.
