I just started learning SLR camera and bought D90. What accessories do you need? Please give me some advice.

2. Cleaning supplies (blowing, lens paper, etc.)

3. tripod (camera price110 to buy a shelf). Cable release device

4. If you don't shoot video, SDHC4 card is enough, and if you shoot video, you must use at least 6 cards.

5. flash memory recommends SB800.

6. Camera bag (shoulder when traveling, shoulder when talking at ordinary times)

7. Waterproof kit (if it can be used, it is very luxurious. You can buy a camera raincoat if you use it normally. There is no need to buy a kit)

8. I wonder if you can use the wireless flash.

9. Two batteries

That's all I can think of. In fact, there is no need to have so many. It all depends on what you do. I'm Canon 7D, and I usually carry a JEEP bag when I go out. There are cameras, batteries, USB flash drives, flashlights, data cables, chargers, rechargeable batteries and so on. Completely according to personal preference.
