What lens does Canon 77D choose to shoot snow-capped mountains and starry sky?

1, change the red circle lens? However, there are few red circle lenses suitable for APS frame.

2. Switch to a more expensive APS lens? For example, Canon 15-85mm and Canon 17-55, but you already have 18-200, and these lenses are more expensive than your body.

If you have money to buy Canon 17-55, I'm afraid it's better to go directly to Nikon D750.

Third, in your current situation, it may be more practical to buy a slightly better super wide-angle lens.

A, tuli11-16mmf2.8 second generation, this is about 2000 yuan in a treasure. The cost performance is good, the picture quality is good, the maximum aperture is F2.8, and you can also shoot the starry sky.

B, Longteng 10-24mm with optical image stabilizer, this seems to be less than 3000 yuan. The cost performance is also good, and there is an optical image stabilizer, which is a bit reluctant to shoot the starry sky. However, if you basically don't shoot the starry sky, then this is better and more practical than Tully.

To sum up, I recommend you to consider Tuli116 second generation or Longteng 10-24 super wide-angle lens, which is a more reliable and practical upgrade.
