Praised by Experts

• ✓Phoblographer highlights the lens as “fantastic… the Bokeh King” thanks to its 11‑blade diaphragm delivering exceptionally smooth bokeh.
• ✓Dustin Abbott praises the “intriguing” f/2.8 aperture combined with a solid 87 × 128 mm, 840 g build that rivals the sharpness of many zoom lenses.
• ✓Lenstip notes the “very high” resolution performance, reaching a peak of 45 lp/mm with even field sharpness across the image.
• ✓B&H emphasizes the high contrast rendering, smooth bokeh, and precisely engraved focus scales that aid accurate macro focusing.

Criticized by Experts

• ✗Reviewers point out the lack of autofocus and image stabilization makes handheld macro work difficult.
• ✗Professionals note that the measured maximum aperture of f/3.2 is slower than the nominal f/2.8, reducing low‑light performance.
• ✗The effective focal length contracts to 68 mm at 1:1 magnification, limiting the expected working distance.
• ✗The lens’s relatively large dimensions and weight are considered bulky for field macro shooting.
