Buy camera lens

I buy lens from yodobashi, but when I talk with friends they always say go to Hong Kong because it's cheaper.
Would anyone know if this is true?

Even in Japan Yodobashi is not usually the cheapest, although they do have a points system which offsets this.

Yes, sometimes lenses are cheaper in Hong Kong, but of course, depends where you buy it there.

In general, I would not worry about it, but you could search on Price HK if you wish

it depends on whether you're buying used or new

new might be cheaper but the lenses will be grey market - no warranty

japan and tokyo in particular has the best market for used lenses. map camera or fujiya camera are maybe the best places in the country.

Thank you for the suggestions, I'll check those places out next time I'm in Japan
