  • Canon EF 28mm f/1.8 USM Lens Review
    ISO 400 1 160 f 1 8 28mm Canon 5D When shot with wide open aperture the lens produced out of focus highlights that were mostly uniformly lit but often carried harshly defined edges The effect is not too distracting but not pleasant either Contrast transitions in the background and foreground OOF areas were somewhere in the middle not too harsh but not too smooth either There was no sign of double edging around back fore ground objects Vignetting f 1 8 full frame vs 1 6x crop 135mm Canon EF 28mm f 1 8 USM showcased noticeable vignetting at f 1 8 when used on a full frame camera Vignetting continued to persist at f 2 8 slowly disappearing by f 4 f 5 6 On an APS C body the lens produced practically no visible vignetting throughout the tested aperture range The lens produced noticeable color fringing that was visible pretty much throughout the aperture range on both APS C as well as FF cameras check the image crop below as well as purple highlights in the urban area shot in the image gallery Axial CA halation was pretty insignificant at f 1 8 disappearing by f 2 8 notice white halos around flowers in the blooming tree shot in the image gallery Generally speaking the lens did not handle color well images at wider apertures were washed out lacking good contrast separation across the entire frame The lens also fell prone to flare at wide apertures and showed noticeable degree of distortion ISO 100 1 4000 f 2 8 135mm 100 crop Title Title Title Title Title Title Title Title Title View the embedded image gallery online at http slrlensreview com web reviews canon lenses canon wide angle 86 canon ef 28mm f18 usm lens review tmpl component print 1 page sigProGalleriac9656a6d57 Lab Tests Please note that MTF50 results for APS C and Full Frame cameras are not cross comparable despite the same normalized 0 1 range used to report results for both types of cameras Canon APS C Canon EF 28mm f 1 8 USM showcased somewhat of a mixed performance on an APS C camera Center performance was quite decent in general at f 1 8 image quality in the center is average but more or less acceptable and from f 2 8 on quality is quite good Regretfully border image quality is quite unimpressive especially at wider apertures from f 1 8 through f 2 8 quality around borders is mediocre at best Even at f 4 quality is just average You need to actually stop down to f 8 to achieve good quality across the frame Here the lens would produce good quality 16in and decent 19in prints which is not that impressive for a 28mm prime Conclusion While center performance is pretty decent border quality is practically disastrous when stacked against other 28mm prime lenses Canon EF 28mm f 1 8 USM would fall somewhere in the bottom of the stack MTF50
