according to the UK website (ww.panasonic.co.uk) below, this sd600 camcorder is 50p
"1080/50p recording (Full-HD, 1920 x 1080, 50 progressive recording) conveys about twice the information of 1080i (interlace) recording to produce the ultimate beauty in image quality, exceeding even conventional Full-HD images. It minimises afterimages and moiré patterns caused by subject motion and renders crisp, detailed images. 64GB SDXC Card can record approximately 27 hours and 30 minutes of 1920 x 1080i high-definition video in HE mode and approximately 5 hours and 20 minutes of 1920 x 1080p full high-definition video in 1080/50p mode"
Hello, I am the Buyer for this product. The SD600 is a US model, though it does have limited distribution. You are correct that it is distributed more prominently in other countries. Some have indicated in the product reviews that it may be PAL, which it is not; this model is NTSC, which is the US standard. Hope that helps.
