The Pergear 50mm f1.8 uses an all-metal construction with an optical formula of 6 elements in 4 groups.
The aperture is a 10 blade design for smooth circular bokeh even when stopped down.
Like several of the other Pergear lenses, this one also does include the lens hood.
The lens hood is a great addition although it’s really not that effective at reducing lens flares or veil flaring. But it is nice as a protective barrier for that front element.
When focusing, the length of the lens does expand, when at infinity the lens is at its shortest length.
Of the three Pergear lenses that I own, the 50mm f1.8 feels like it has the worst quality to the build. Nothing is wrong with the lens per se, but when focusing there is a little grinding with the rotation.
The focus throw is probably about 170 degrees.
Turning the aperture feels stiff and satisfying although I do wish it wasn’t de-click. Often times the aperture marks on these cheap lenses are not correct.
I’ve included some shots with my hands in the frame so you can get a better sense of scale.
