  • Carl Zeiss Jena 29mm f/2.8 (M42) Lens Review
    other Carl Zeiss Jena M42 manual lenses I used a generic Fotodiox M42 to EOS adapter without AF confirmation I used camera in aperture priority mode which along with the fully manual are the only two modes available to anyone using this type of an adapter Summary Lens Composition 7 elements in 7 groups Angular Field 73 degrees Minimum Focus 25cm 0 82ft Focusing Action MF f stop Scale f 2 8 f 22 manual Filter Size 55mm Lens Hood N A Weight 240g 8 46oz Dimensions 56x52mm 2 2x2 Lens Case N A Field Tests Carl Zeiss Jena MC 29mm f 2 8 left me with a bag of mixed feelings the lens was tack sharp in the center throughout the tested aperture range and extremely soft around borders almost with all aperture levels I say almost because quality improves somewhat at smaller aperture levels Vignetting f 2 8 full frame vs 1 6x crop The lens exhibited moderate amount of vignetting on an full frame Canon 5D with wide open aperture Vignetting is pretty much gone once you stop down to f 4 On an APS C camera the lens did not show any vignetting throughout the tested aperture range Colors were a little bit washed out and the lens fell prone to occasional flare Carl Zeiss Jena MC 29mm f 2 8 also exhibited some color fringing in challenging lightning situations both in the center as well as around borders ISO 100 1 1600 f 2 8 29mm 100 crop Sample images 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 Canon APS C The lens showed rather extreme range in performance Image quality in the center was exceptional streight from f 2 8 reaching very impressive levels by f 4 Regretfully border performance was simply disastrous with wide open apertures And while border quality improves with stopped down it does not reach acceptable levels until f 8 At its best from f 8 to f 11 the lens is capable of producing outstanding 16in and decent 19in prints which is can be considered pretty decent Conclusion It s expected that wide angle lenses would typically produce somewhat softer results around borders The emphasis here is on the word somewhat since Carl Zeiss Jena 29mm f 2 8 shows inadequate performance around borders even with this lower expectation So if you care about border sharpness this lens would be practically unusable with wide aperture settings MTF50 Line Width Inch on the Print 29mm Normalized raw MTF50 29mm Chromatic aberration was somewhat on a higher level with wide open apertures averaging 1 1px around corners and significantly less 0 3px in the center CA is reduced with stopped down aperture and by f 8 reaches minila levels averaging 0 4px across the frame Image borders 29mm 100 crop f 2 8

    frame cameras or even a Four Thirds camera then both MM as well AE versions of the lens should work just fine for you But enough on compatibility Contax Planar T 50mm f 1 4 is a tiny lens by all standards and some might find it somewhat hard to operate the focus ring is broad enough to grasp comfortably but the aperture ring is way too close to the camera body and thin enough to make it somewhat hard to grasp Why is this a problem After all you can preset the aperture and then focus the lens normally or even use an engraved DOF scale for hyperfocal distance for focusing Well Planar has absolutely no coupling with your lens so when you stop down the aperture the diaphragm actually closes down This in turn darkens your viewfinder Manual focusing through viewfinder with no visual aids like split circle screen by itself is not the easiest task and with the lens stopped down to about f 5 6 the viewfinder gets so dark that focusing the lens accurately becomes practically impossible Overall image quality that the lens showcased in the field was pretty good From about f 4 the lens showed pretty consistent results on both APS C as well as FF cameras throughout the picture frame that is there did not seem to be any significant difference in image quality from the center to the borders The widest aperture setting is where the image quality was noticeably different across the image frame with border quality noticeably worse then in the center One can argue that softer borders at the widest aperture settings is not much of a problem since you would want to have a smooth bokeh with a better separation between the subject in focus and out of focus areas ISO 400 1 250 f 1 4 50mm Canon 5D Speaking of the bokeh From the sample picture above as well as pictures in the sample gallery you can notice that when shot with wide open aperture Carl Zeiss Planar T 50mm f 1 4 produces occasional harshly lit edges around out of focus highlights although the OOF highlights themselves are pretty uniformly lit Other then that though the lens showed pretty decent characteristics including smooth transitions in the fore background and lack of any double edging around out of focus objects all of which should make the look and feel of bokeh quite pleasing On APS C type cameras with 1 6x crop sensor the lens showed very minimal vignetting at wider apertures but the lens did not fare as well on a full frame body where it showed noticeable vignetting at f 1 4 which was reduced at f 2 and became almost non existent at f 4 Color rendition was quite good but the resulting images were somewhat cooler compared to similar lenses from Canon and Sigma The lens did not exhibit any barrel distortion Color fringing was very minimal across the frame The
