First Impressions

• AF is fast, accurate and quiet. On par with the Canon RF 85mm f/2 in my opinion.
• Not as sharp as the Canon 85mm f/2, but good enough for most use cases.
• Aperture moves slightly slower than Canon lens. Causing higher shutter release latency if stopped down.
• Unlike Canon RF lenses, it’s aperture does not stop down when camera powers off. So direct sunlight might burn the shutter blades (verified with paper).

初步印象

• 自动对焦准确，速度快且安静。感觉和佳能 85mm f/2 水平相当。
• 锐度不如佳能 85mm f/2，但大多数情况下应该足够好。
• 光圈收缩速度相比佳能的 RF 镜头稍慢，在缩小光圈拍摄的情况下会导致快门延迟明显增加。
• 佳能的 RF 镜头在相机关机后会收缩光圈，这个镜头不会。所以阳光可能会烧到快门（下图验证）。
