A nice lens with decent image quality and reasonable price. As a Macro lens it suits the needs. Sharpness and contrast are on the very good side. Gives a macro rendition of 1:1
Image sharpness is very good even for a tendency for excellence, Contrast is very good, The best point for this lens is its price; Compared to similar products, lenses from the camera manufacturers are much more expensive
Inner construction; The focus limiter is very fragile and might disengage/break from first attempt of engaging it, Lens hood is screw on and whenever attached the lens cap cannot be used, creating an inconvenience, The focusing ring rotates when on AF
