I'll start with a small spittoon. Do you need help with a uv mirror and a hood?

First of all, UV mirror and hood are photographic accessories to protect the lens and reduce the glare of the lens. For the lens of small spittoon, whether it is necessary to match UV mirror and hood depends on your use and demand.

If you often expose your camera to outdoor or harsh environment, it is recommended to equip it with a UV mirror to protect the lens from dust, rain and fingerprints. In addition, the UV mirror can also reduce the lens blur caused by the change of internal temperature of the lens caused by the change of strong light.

As for the hood, it is mainly used to reduce lens glare and halo. When shooting in strong sunlight or complicated light, using a hood can reduce the influence of glare and halo on photos. In addition, the hood can also prevent the lens from being accidentally bumped or scratched.

To sum up, if your use environment is harsh or the lighting in the shooting environment is complicated, it is recommended to equip you with a UV mirror and a hood. On the other hand, if your use environment is relatively stable and the lighting in the shooting environment is relatively soft, then you can consider not using these accessories.
