Help me recommend a wide-angle lens, which one should I choose, Longteng 15 30f2.8 or Sigma 20mm f 1.4?

If I choose from these two lenses, I will personally choose Sigma 20mm, 1.4f, whose focal length will be larger than Longteng 15-35, but the aperture of 1.4 will be much larger than 2.8.

Shoot starry sky, night scene, star orbit, etc. Be sure to master a few photography skills.

1. Wide-angle lens, because the wide-angle lens has a wider field of vision, this starry sky, landmark and reference object will be very visual.

2. The aperture is large enough, because three parameters control whether a perfect starry sky photo can be taken. ISO sensitivity, aperture, shutter. The larger the aperture, the larger the shutter can be, and it is not easy to blur. ISO can be adjusted to the maximum, and the photos will not be blurred. 1.4 aperture lens is preferred.

3. The weather is the best, the clouds are clear, there are no obstacles, and there is no light pollution to the light source.

4. Geographical location, generally in villages, plateaus, lakes, mountains, etc. This geographical environment makes it easy to take a perfect picture of the starry sky.

Thanks for sharing, Wei.
