Shopping for camera equipment, be it lenses, camera housing, cards or compact cameras, it's recommended to pick one of the below suppliers. Many foreigners have recommended these shops, so they're considered pretty reliable. Make sure that you get a receipt for everything you buy and also ask if it's a copy or original as many shops carry both!

A word of caution though, Tin Cheung Camera , carry both officially imported and gray market cameras and lenses. The gray market stuff would obviously be cheaper, but if you want want officially imported goods, make sure you ask them before you buy!
They have many branches including in main shopping areas like Mongkok, Tsim Sha Tsui and Causeway Bay. Although they are a large chain store, depending on your payment method (cash or different kinds of credit cards) you can often bargain with them to get a better price, usually cheaper than their officially listed prices.
2. Citicall is another chain to try. They are similar to Broadway with many branches around the city. You can also bargain with them like Broadway.
3. Fortress is yet another large chain stores you can try. I previously did not list them because they did not used to give much discount, but recently, I have asked about prices of Canon lenses there and they seemed to give pretty good discount. Some of the shops also have some rarer lenses in stock like the Canon EF 14mm f/2.8L USM.
* Avoid camera stores in Nathan Road, they give you good prices but when you ask for the unit they only show you the model unit and claim that its the last unit.. when in doubt look for the Hong Kong tourism logo seal.. at least that will assure you that they are tourist friendly and you will definitely get good quality and service.
A Final Word of Warning!
Finally, just a few words of advice on shopping for cameras and lenses in Hong Kong. Avoid shops that have “Tax Free” sign prominently displayed outside or inside the shop. These shops are usually scammers, where “bait and switch” is common . They usually have lots of sales person inside a smallish shop. The ratio of salespersons to shop floor area/clients would be far to high to be profitable if these were legitimate honest shops. There is no sales tax or duty in Hong Kong except hard liquor and tobacco anyway. The “Tax Free” sign is basically just a trap to attract unsuspecting tourist.
