What lens does the digital camera choose to take a panoramic view?

Fisheye lens.

I recommend some fisheye lenses.

The classic 8MM fisheye was introduced long ago, and many people use it to shoot panoramic images. The imaging is clear and wide enough to be used for full-width or half-width SLR cameras. It's just that the price of Bank of China is relatively high, but the warranty of Bank of China is 3 years, and the after-sales is more secure than parallel imports.
