Pros & Cons

👍 Pros

  • The 21mm focal length allows for wide-angle photography, capturing expansive scenes effectively.
  • With an F1.4 maximum aperture, this lens excels in low-light conditions and creates shallow depth of field.
  • Manual focus provides precise control over critical focusing, which can be beneficial for artistic compositions.
  • The ability to fit Series 8 filters via a dedicated hood offers creative control over light and effects.
  • A minimum focus distance of 0.7m/27.5" enables close-up shots with detailed subject separation.

👎 Cons

  • The reliance on a dedicated hood for Series 8 filters might add an extra accessory to carry or manage.
  • A 21mm focal length, while wide, may not suit all photography styles and could require careful composition to avoid distortion.
  • The F16 minimum aperture could limit depth of field options when a very narrow aperture is desired for specific effects.
