  • Voigtlander Nokton 58mm f/1.4 SL II Lens Review
    4 Introduction Cosina which currently owns the Voigtlander brand name announced release of the new SL II series of SLR lenses in the Fall of 2007 Needless to say that this announcement caught many by surprise positive surprise obviously since everybody believed that Cosina discontinued the SL lenses for good back in 2004 It remains to be seen whether Cosina will decide to re introduce the entire range of SLR lenses but at the moment the company released two standard fixed focals 40mm f 2 Ultron and 58mm f 1 4 Nokton Both lenses are available in Nikon Ai S and Pentax KA mounts but unlike their predecessors the new Ai S variants also have embedded CPU controllers that provide metering compatibility with modern digital SLRs Currently new samples of Voigtlander Nokton 58mm f 1 4 sells for US 379 at online resellers like CameraQuest When used on APS C type cameras with 1 6x crop factor the 58mm Nokton turns into a medium telephoto lens with a field of view similar to that of a 92mm lens on a full frame body The optical construction of the lens consists of 7 elements in 6 groups Build quality is pretty good the new versions of SL series have black finish as compared to black chrome finish for the first generation lenses The barrel is made of metal as is the aperture ring Focus ring is rubberized a change compared to the older models Another change is the snap on front cap which is now plastic rather then metal screw in type The lens no longer features bayonet lens hood thread and instead lens hood has to be screwed in to the lens filter thread The filter ring is pretty smooth but the aperture ring feels a bit rough the ring

  • Voigtlander APO Lanthar 90mm f/3.5 SL Lens Review
    Minolta and Olympus OM mounts When testing the lens on Canon cameras I used a generic non AF chipped Nikon F to EOS adapter from Fotodiox The lens is designed for full frame cameras and on APS C bodies with 1 6x crop factor the field of view of the lens is similar to that of a 144mm lens on a full frame body The factory box contains Voigtlander APO Lanthar 90mm f 3 5 SL lens front and rear caps manual and registration card Summary Lens Composition 6 elements in 5 groups Angular Field 27 degrees Minimum Focus 50cm 1 64ft Focusing Action MF f stop Scale f 3 5 f 22 manual Filter Size 49mm Lens Hood Square metal optional Weight 390g 0 85lb Dimensions 58x64mm 2 28x2 51 Lens Case None Field Tests Voigtlander APO Lanthar 90mm f 3 5 SL showed very solid overall performance in the field Images were sharp corner to corner throughout the aperture range on both APS C and FF cameras Canon bodies with accurate but a little bit saturated colors and excellent overall contrast Like with most Voigtlander telephoto lenses the APO Lanthar 90mm features extremely precise focusing it takes almost a full 360 degree turn to focus from infinity to the closeup While I personally prefer lenses with precise focusing it might also mean some missed opportunities when you need to focus the lens quickly to capture a moment You can probably mitigate this by presetting the lens in anticipation but naturally there are limits to this method as well And speaking of the closeup the lens sports a pretty short minimum focusing distance 50cm 1 64ft which is quite rare in non macro telephoto lenses Vignetting f 3 5 full frame vs 1 6x crop The lens showed very low level of vignetting with wide open aperture on a full frame body Of course considering that this is not the fastest lens around it does not come as a major surprise On an APS C body the lens showed basically no vignetting throughout the tested aperture range Voigtlander APO Lanthar held up very nicely against flare even at its widest aperture and showed no visible barrel distortion Color fringing was basically non existent across the frame ISO 100 1 500 f 3 5 90mm Title Title Title Title Title View the embedded image gallery online at http slrlensreview com web reviews voigtlander voigtlander telephoto 366 voigtlander apo lanthar 90mm f35 sl lens review sigProGalleriaf24b1c2385 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 Cross system i e Canon vs Nikon results are also not comparable Nikon APS C Coming soon Nikon FF Coming soon Canon APS C The lens showcased pretty solid performance throughout the aperture range Center was outstanding straight from f 3 5 and while performance degraded ever slightly towards f 11

    the lens The camera will still retain the AF confirmation so this should simplify the focusing a little bit The second implication is that the lens does not have a traditional DOF scale no aperture ring no DOF scale hence you will not beable to rely on hyperfocal focusing method Like most manual focus lenses Voigtlander APO Lanthar 125mm f 2 5 Macro SL sports a pretty precise focusing system maybe even an overkill for some users you will end up rotating the focusing ring almost two full 360 degree turns to go from the infinity to the minimum focusing distance As you can imagine this could be a major advantage if you re shooting still objects but try focusing quickly to catch a moving target like an insect Putting aside these somewhat unusual characteristics the lens demonstrated a pretty solid and fairly consistent performance in the field Image quality remained adequately sharp across the picture frame and throughout the tested aperture range At least if there were any differences they were not easily noticeable visually There did not seem to be any significant difference in image quality between images taken with APS C and FF cameras which is obviously a very positive sign ISO 400 1 125 f 2 5 125mm Canon 5D When shot with wide open aperture Voigtlander APO Lanthar 125mm f 2 5 SL Macro produced well rounded out of focus highlights with an occasional harshly lit edges a signature of lenses with some over correction for spherical aberration Contrast transitions in OOF areas were pretty smooth creating a nice feel and overall separation between the fore background and the object of the focus There was also no sign of double eding around background and foreground OOF objects Vignetting f 2 5 full frame vs 1 6x crop 125mm The lens showed moderate amount of vignetting at f 2 5 on a full frame Canon 5D which is somewhat surprising for a moderately long telephoto Vignetting remained present at f 2 8 and to a lesser degree at f 4 with f 5 6 finally being complete free of the artifact And on APS C camera the lens showed basically no vignetting throughout the tested aperture range On the positive side Voigtlander APO Lanthar 124mm f 2 5 Macro showed very decent handling of flare The two images below demonstrate the degree of this artifact with a direct light source positioned near the picture frame The sun was hitting the lens at 50 degrees As can be seen from the samples at wider apertures flare resulted in a slightly reduced contrast across the entire picture frame Not very helpful but quite common among most lenses Lower apertures showed even better handling with practically no impact on the image quality Left ISO 100 1 640 f 2 5 Right ISO 100 1 60 f 8 As expected from a medium telephoto lens Voigtlander APO Lanthar did not show any noticeable distortion Color handling was quite good with

    demonstrate solid performance in its default non tilted shifted mode to begin with And unfortunately Mamiya 645 35mm f 3 5 did not seem to quite match this criteria as the lens showed somewhat mixed performance in the field Image quality was pretty decent with stopped down apertures however quality around borders seemed to suffer quite noticeably at f 3 5 Vignetting f 3 5 full frame vs 1 6x crop The lens showed minimal level of vignetting at f 3 5 on a full frame camera and once stopped down to about f 5 6 vignetting is pretty much gone The fact that vignetting is quite low here can be attributed to the relatively small maximum aperture and larger imaging circle which extends beyond the coverage of a full frame sensor Naturally on an APS C body the lens shows practically no vignetting throughout the aperture range Color reproduction was quite good with images carrying good amount of contrast but unfortunately the lens fell prone to both lateral as well as axial chromatic aberration Lateral CA was noticeable to the naked eye primarily around borders pretty much throughout the aperture range Halation was quite minimal at f 3 5 and disappeared with stopped down apertures ISO 100 1 1250 f 3 5 35mm 100 crop Title Title Title View the embedded image gallery online at http www slrlensreview com web reviews misc mamiya mamiya wide angle 645 470 mamiya 645 35mm f35 lens review sigProGalleria304e8f373c 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 Mamiya 645 At this time I do not have plans to conduct tests with any medium format cameras Canon APS C Mamiya 645 35mm f 3 5 showed mixed performance on an APS C body On one hand image quality in the center was very good throughout the aperture range On the other hand border image quality suffered especially at wider apertures At f 3 5 and f 4 lens performance was kind of average improving in the f 5 6 f 11 range The lens reaches its peak performance around f 5 6 where it is capable of producing outstanding 16in and decent 24in prints Conclusion Not what I would call the best performing wide angle lens on the block Border image quality at wider aperture levels is disappointing if the lens shows such a weak border performance on an APS C body imagine what results it will produce on a medium format camera MTF50 Line Width Inch on the Print 35mm Normalized raw MTF50 35mm Chromatic aberration on an APS C type camera under control in the center where CA averaged measly 0 3px across the tested aperture settings Border CA was noticeably higher and was increasing with stopped down apertures going from 0 9px at f 3 5 to 1

  • Mamiya 645 45mm f/2.8 Lens Review
    71 Lens Case N A Field Tests The lens showed rather mixed performance in the field Image quality in the center remained quite decent across the apertures on both APS C as well as FF cameras However borders were visibly softer at wider apertures and seemed to retain softness even once stopped down which is not quite typical for most lenses ISO 400 1 100 f 2 8 45mm Canon 5D When shot with wide open aperture the lens produced pretty uniformly lit OOF highlights There was an occasional harshly lit edge but the effect was not too distracting Contrast transitions in the OOF background and foreground areas were not particularly pleasant retaining a little bit of harshness but there was no visible double edging around OOF objects Vignetting f 2 8 full frame vs 1 6x crop 200mm Mamiya 645 45mm f 2 8 showed minor degree of vignetting with wide open aperture on a full frame body which pretty much disappears by f 4 On an APS C body vignetting is practically not visible even with the widest aperture Color reproduction was pretty decent with images carrying adequate amount of contrast across the apertures But the lens exhibited some color fringing mostly around borders check the chair on the left side of the image crop below There did not seem to be any noticeable axial CA and flare seemed quite well under control ISO 100 1 2000 f 2 8 45mm 100 crop Title Title Title View the embedded image gallery online at http slrlensreview com web reviews misc mamiya mamiya wide angle 645 471 mamiya 645 45mm f28 lens review sigProGalleria45c0d66bd3 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 Mamiya 645 At this time I do not have plans to conduct tests with any medium format cameras Canon APS C Mamiya 645 45mm f 2 8 failed to impress in the lab Center performance was decent throughout the tested aperture range not the highest among standard angle primes but quite good However border image quality was pretty average even on a mediocre side And unfortunately it remains mediocre throughout all aperture settings The overall performance across the frame remains kind of on about the same level so there s really no peak to speak about The lens would produce outstanding 11in and decent 19in prints which is absolutely unimpressive for a standard angle prime Conclusion Unimpressive kind of sums it all up for this lens with this performance the lens would fall somewhere in the bottom half of all standard angle primes tested so far I m referring to primes for 35mm systems here MTF50 Line Width Inch on the Print 45mm Normalized raw MTF50 45mm Chromatic aberration on an APS C body was sort of a mixed bag Center CA remained quite manageable
