Is the photo taken by the waterproof sleeve SLR clear?

Install the waterproof shell strictly according to the corresponding model of your machine, which is generally more expensive and the design is in place. No problem. At least the material, transmittance and color of the lens segment have little influence, but there are still some.

Try to buy a better waterproof shell, a common plastic bag, which has a great influence on the photo taking effect. You can do the same. If you think it's expensive to buy a waterproof case for a SLR, buy an underwater camera, with three cards, 1-2k.

For short-term use, rent one.

Try to dive and take photos, or try to use some better and safer accessories. One is photos, and now it is camera safety.
