Thanks for the share mclicks77 !
It's a good reference shop so far ;-)
But i don't any filter sell there .
If you want filter, they have it right behind the cashier counter. Mostly Hoya ones. It is slightly cheaper than other places that sell it. I bought a 58mm HMC at $25-2% cash payment, so its $24.50.
Look under accessories in their website and you can find filter prices there. If you stay Ang Mo Kio or in the west, might as well just get from MS or Parisilk. Save the transport fee. But in general the pricing is good.
