Product photography: my job is to shoot bags. Due to the development needs, I will join model photography in the future. What equipment and props do I need to buy?

I don't think you lack anything with your existing equipment. The lens recommends a small steel gun. Although it is a little out of focus, it is good to move the focus down artificially when focusing. For example, my D70 small steel gun moves forward 2 ~ 3 cm, and when I take a portrait, the focus is on my nose, and then on my eyes. If shooting models and products outdoors, the aperture should be at least reduced to f5.6, and the problem that the aperture of small steel gun 135mm is reduced to F5.6 can be ignored. After all, this lens is more affordable. For outdoor shooting, if you have an assistant, you need to buy a large-area reflector. If there is no assistant, you need to buy two household flashlights, wireless flashers, reflective umbrellas and special brackets for flashlights. These add up to about 1500 yuan. You mentioned the reflection of objects. Did you add a soft cover to the flash, or bought a special soft box for shooting products? As long as you don't use strong light when shooting, there is a certain distance between the light source and the subject, so there is generally no reflection problem. For more questions about photographic lighting, you can go to Blitzkrieg's website, which is a website dedicated to photographic lighting, and I think it is still helpful to you.
