Seeing as I will be in Japan for about 20 hours, I thought I might take the opportunity to look at some purchase whilst I am there. Does anyone know how pricing for Tamron, Sigma and of course, Pentax lenses compares in Japan, as opposed to USA, and Australia? I will be able to purchase Duty Free due to the fact that I will be on route to LA during my layover. Are there any Japanese PDML'ers who could suggest some places to shop that are close to Narita and offer good prices and equipment selections?
TIA, Tan.
