    is f 16 The filter size is 49mm On APS C cameras with 1 6x crop factor like Digital Rebel XTi the lens has a field of view similar to that of a 45mm lens on a full frame body To use the lens on a Canon EOS body I used a generic non AF chipped Fotodiox Olympus OM to EOS adapter you will end up operating the camera in manual or aperture priority modes with all but center weighted metering disabled Summary Lens Composition 7 elements in 7 groups Angular Field 75 degrees Minimum Focus 30cm 11 8in Focusing Action MF f stop Scale f 3 5 f 16 manual Filter Size 49mm Lens Hood N A Weight 180g 6 3oz Dimensions 31x59mm 1 2x2 3 Lens Case N A Field Tests For a sub 40 lens Olympus OM 28mm f 3 5 was full of surprises the lens was tack sharp in the center across the entire tested aperture range Border quality matched the center except at f 3 5 where the lens seemed to produce slightly softer results on a full frame body Vignetting f 3 5 full frame vs 1 6x crop The lens showed insignificant amount of vignetting on a full frame Canon 5D with wide open aperture Vignetting is non existent on an APS C camera straight from f 3 5 The results are not very surprising considering the lens is relatively slow The color reproduction was pretty accurate however the lens showed somewhat higher levels of color fringing at f 3 5 On the other hand the lens held its ground well against flare and distortion ISO 100 1 2000 f 3 5 28mm 100 crop Olympus OM Zuiko 28mm f 3 5 image gallery coming soon 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 Four Thirds Coming soon Canon APS C Olympus OM Zuiko 28mm f 3 5 produced very solid results in the lab with excellent center performance throughout the aperture range and equally good border performance Overall performance is distributed evenly across the frame which is obviously a major plus for any lens At its peak the lens is capable of producing outstanding 16in and decent 24in prints Conclusion The lens clearly benefits from a relatively small maximum aperture but while the lens does not show the best absolute results it demonstrates pretty solid overall performance and will be suitable for most applications MTF50 Line Width Inch on the Print 28mm Normalized raw MTF50 28mm Chromatic aberration was rather high around borders on an APC C body at f 3 5 it exceeded 1 7px and remained on a somewhat high level through the rest of the aperture averaging 1 1px even at f 11 CA in the center was slightly lower averaging 1px at f 3 5 and dropping to 0 5px with

    shot with wide open aperture Unfortunately highlights carried distinct bright edging which is common among lenses over corrected for spherical aberration Contrast transitions in near and far OOF areas remained more or less smooth but the lens showed minor level of double edging around blurred background objects Vignetting f 2 full frame vs 1 6x crop 35mm The lens showed pretty noticeable vignetting on a full frame body at f 2 Vignetting actually continues to persist even once you start stopping down the lens and does not go away completely until f 5 6 Disappointing On an APS C body the lens handled vignetting much better obviously due to the smaller frame coverage of a cropped sensor Still while not as pronounced as with a FF body the lens did show very minor vignetting on an APS C body at f 2 The lens carried a rather low amount of contrast at wider apertures which made images look washed out and lifeless Contrast does not improve until the lens is stopped down to about f 8 The lens also produced pretty heavy halation axial CA with wide open apertures Notice well defined haloes around bright white tree flowers in the first image in the image gallery Color fringing lateral CA was present as well predominantly around corners The lens also fell prone to pretty heavy flare at wider apertures and aperture ghosting with smaller aperture levels All that somewhat surprising for a multi coated lens Finally OM Zuiko 35mm f 2 showed minor degree of barrel distortion ISO 100 1 1000 f 2 35mm 100 crop Title Title Title View the embedded image gallery online at http slrlensreview com web reviews olympus olympus wide angle 389 olympus om zuiko 35mm f2 lens review sigProGalleria9ccba329c0 Lab Tests Please note that MTF50 results for APS C and Full Frame cameras as well as cameras from different manufacturers are not cross comparable despite the same normalized 0 1 range used to report results for all types of cameras Four Thirds Coming soon Canon APS C Image resolution was somewhat of a mixed bag with Olympus OM 35mm f 2 The lens showed rather weak performance at f 2 both in the center as well as around borders Quality improves once stopped down to f 2 8 where the center quality is already pretty good and border quality is quite decent as well But the lens shines in the f 4 f 11 range with ever slightly better overall results at f 8 At its peak f 8 the lens is capable of delivering outstanding 19in prints and you can get pretty decent quality 24in prints in the entire f 4 f 11 aperture range Conclusion Performance in the f 4 f 11 range is pretty much what you would expect from a solid wide angle prime Quality at f 2 is disappointing though Can t say that this is unusual though majority of wide angle lenses show some weakness at their widest aperture

    down helped improve the quality borders did not seem to improve significantly at f 4 making f 5 6 the largest aperture that was producing acceptable quality across the frame ISO 400 1 40 f 2 8 35mm Canon 5D When used with wide open aperture the lens produced OOF highlights that were round and mostly uniformly lit but with distinct bright outline so far this seems to be pretty typical for most wide angles Contrast transitions in near far OOF areas remained rather harsh harsher then what I d like to see in a good portrait lens The lens did not show any major sign of double edging around blurred objects Vignetting f 2 8 full frame vs 1 6x crop 35mm On a full frame camera Olympus OM 35mm f 2 8 showed quite a noticeable vignetting at f 2 8 Vignetting continued to persist at f 4 albeit at a lower level but became negligible at f 5 6 The lens behaved better on an APS C body taking advantage of a reduced frame coverage of a smaller sensor and at f 2 8 vignetting is barely noticeable and by f 4 it is practically gone Considering that a Four Thirds system will have an even smaller sensor vignetting should not be a problem there at all At wider apertures Olympus OM Zuiko 35mm f 2 8 produced images that carried pretty low level of contrast making images look a bit washed out another common characteristic this lens has with its faster cousin Contrast levels remain low until about f 5 6 f 8 which again might not be acceptable to some users The lens produced some color fringing lateral CA mostly around borders throughout the aperture range It also fell prone to some flare with wide open aperture and showed a minor degree of barrel distortion ISO 100 1 1600 f 2 8 35mm 100 crop Olympus OM Zuiko 35mm f 2 8 image gallery 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 Four Thirds Coming soon Canon APS C The lens showed pretty solid performance in the center Image quality was outstanding straight from f 2 8 and even improving slightly at f 4 and beyond Not too shabby and nothing to complain about Performance around borders is a different story though Image quality around borders lags center quite noticeably at f 2 8 Results here are mediocre at best Things improve a bit when stopped down to f 4 and here border performance reaches decent levels By f 5 6 border quality reaches quite an impressive level and stays at these impressive levels through the rest of the aperture At its peak in the f 5 6 f 11 range the lens is capable of producing outstanding 19in and decent 24in prints which is comparable to the resolution
