Sony 4K camcorders different models for Thailand

Hi, I was looking for buying a camcorder and noticed at Fortune Tower in Bangkok the electronics shops have the Sony FDR AXP55. 

However, this model doesn't seem to be available in the UK. Over there it's the AXP-53. Looking only the cameras seem virtually the same but the Thai / Asia version has a built in projector (and is slightly more expensive).

Is it normal to have different models in Asia? And does any body know, are the cameras actually the same? 

This is a link to the two being compared and below that is the official SOny Thailand page for the AXP 55 . 

P.S. If anybody can recommend this camera or any other similar 4K cameras to check I'm not looking for the wong thing that would be great. 

Thanks
