go map camera at shinjuku, price at at least 10% less than yodabashi mage store. google it and you find it. btw there is not shop front, it is at 2 and 3 level. need a bit of time to find it.
I suppose for 20mm I should be to get it at bns around 500, so what is likely a price for 25mm 1.4 ? Both shop and bns section? For normal people and street snap , will 25 which will be 50mm too big too the crop to be?
