I am going to Hong Kong recently and want to buy a Canon digital camera there. My budget is about 4,000. Please give me some advice. personal use

You can check the Hong Kong price website, .hk/

Now the market for photographic equipment in Hong Kong is also very deep. It is similar to the JS method in the mainland. You need to understand the market in detail and be determined. That's good. Usually I go there to buy models that are not available in the mainland, such as Sony's Milkshake 3, A850, etc. It's safer to go to a large photographic equipment store, as it may be a little cheaper during promotions.
