  • Voigtlander Color Skopar ASPH 20mm f/3.5 SLII Lens Review
    with APS C and FF cameras Recommendation and User Reviews Tweet Page 1 of 4 Introduction Voigtlander a brand name owned by Cosina of Japan is fairly well known among rangefinder aficionados The company is one of the only three that currently still manufactures Leica M39 compatible lenses Cosina made a splash in late 90s when it released a limited set of SL lenses for Nikon Pentax and Olympus lenses There was even one lens model manufactured for the Canon EF mount the now famous Voigtlander APO Lanthar 125mm f 2 5 SL The word splash is relative here since Voigtlander is not really a brand name known among most SLR users and so even during the heyday of the SL range the lineup was not particularly popular compared to the 3rd party mainstream manufacturers like Sigma Tokina or Tamron at least The original SL lineup was discontinued in 2005 but Cosina recently re introduced its SLR lenses with the Color Skopar ASPH 20mm f 3 5 SLII being the latest model The lens retails for US 550 as of January 2010 although used copies can be found for US 450 The optical construction of the lens consists of 9 elements in 6 groups that includes a single aspherical element The lens is tiny particularly if you compare it to such ginormous lenses like Carl Zeiss Distagon T 21mm f 2 8 or even Canon EF 24mm f 1 4L USM The lens measures 63x28 8mm 2 4x1 14in and weighs only 205g 7 2oz The barrel is all metal the aperture ring is rubberized and the the aperture ring is knurled for more comfortable grip The barrel extends a few millimeters when focusing towards closeup The lens focuses down to 20cm 0 65ft and has a 58mm screw in

  • Voigtlander Nokton 35mm f/1.4 (M) Lens Review
    by Cosina created a lot of excitement in the otherwise stale market Original Ultron ASPH 35 1 7 received fairly positive overall reception from many users inexpensive US 370 new decent build aspherical glass good performance What not to like here Then Cosina made an even bigger splash announcing the fastest 35mm rangefinder lens ever designed the famed Nokton ASPH 35mm f 1 2 came with big fanfares but the lens received mixed reviews as many thought that Cosina pushed the envelope too much with the optical design not quite suitable for such speeds Some users swore by that lens others complained about the lack of character at wider apertures I am a reasonably happy owner of the Nokton 35 1 2 but that s a different story review I mean Then Cosina announced the end of life for the original Ultron ASPH 35 1 7 and its replacement with Nokton 35 1 4 Rejoice photographers More compact lens half stop faster and still reasonably priced On top of that Nokton was available as single coated and multi coated version Nice Except aspherical glass was gone and after a little while online forums started to to collapse overdramatization obviously under the complains of Nokton 35 1 4 users claiming that their copies did not perform well at wide apertures Some thought the problem was in shady quality control others thought it was sample variation with wider manufacturing tolerances yet some who actually did enough testing argued that the Nokton 35 1 4 exhibits focus shift common to all fast lenses ISO 160 1 2000 f 2 35mm Focus shift is not a new phenomenon there are a few good write ups on the web worth reading but in a nutshell the focus shift occurs in lenses predominantly due to spherical aberration left uncorrected which shift the focusing plane at different aperture levels Different designs exibit focus shift at different aperture levels I own a Zeiss C Sonnar 50 1 5 ZM which also exhibits focus shift and the original copy I purchased exhibited focus shift at f 1 4 and f 2 the common term used by many is the lens is optimized for f 2 8 since from f 2 8 and smaller apertures focus shift does not show up in images Yet other lenses have exhibited focus shift at middle apertures like f 4 or even f 5 6 Focusing distance plays the major role in the focus shift which is most noticeable at distances near MFD and less so at infinity But basically by employing more complex designs including aspherical surfaces lens designers can limit or even completely eliminate focus shift in a fast lens for example Summilux 50mm f 1 4 ASPH which does not show any focus shift Why am I rumbling on for so long Well Nokton 35 1 4 does have focus shift and that s the most annoying part of handling this lens for me at least By ditching aspherical elements from

  • Voigtlander Super Wide Heliar ASPH 15mm f/4.5 (M) Lens Review
    15mm f 2 8 which by the way is also manufactured at Cosina factory costs SU 4 600 Even the newly released M mount version of the lens costs only US 599 a fraction of all other alternatives How about that for a splash The optical construction of the lens consists of 6 elements in 8 groups with a single aspherical element in the rear group The formula is identical to the one used in the now classical M39 screw mount version of the lens The build quality is quite good with all metal construction including the focusing and aperture rings The lens is surprisingly compact and light particularly for such a wide lens measuring 60 x 38mm 2 36 x 1 49in and weighing 156g 5 5oz The minimum focusing range of the lens has increased slightly going to 50cm instead of 30cm for the LTM version although on M8 the rangefinder coupling works only to 65cm The aperture ring steps in half f stop increments from f 4 5 to f 22 Like with the LTM version new Super Wide Heliar ASPH 15mm f 4 5 has a built in lens hood but now sports a front 52mm filter thread The lens was designed for traditional 35mm film rangefinders and so if you re using it on an APS H type Leica M8 the EFOV of the lens will be 20mm while on APS C type Epson R D1 it will be 23mm The manufacturer s box includes Voigtlander Super Wide Heliar ASPH 15mm f 4 5 lens front and rear lens caps and a manual Within the scope of this review the lens was tested only on Leica M8 Summary Lens Composition 6 elements in 8 groups Angular Field 110 degrees Minimum Focus 50cm 19 6in Focusing Action MF f stop Scale f 4 5 f 22 manual Filter Size 52mm Lens Hood Integrated metal Weight 156g 5 5oz Dimensions 60x38mm 2 3x1 49 Lens Case N A Handling When redesigning the Super Wide Heliar Cosina did one thing right listened to the user feedback While the original LTM version of the lens was superb it had two major problems The lens was not rangefinder couplesd and did not have a filter thread The lack of rangefinder coupling effectively required you to guess focus While this seems like a fairly big limitation in real life you can deal with this by using hyper focal distance The super wide focal length of the lens actually makes your life easier here by setting the lens at f 8 you get a working range that spans the entire focusing range of the lens from minimum to the infinity The massive DOF masks small focusing errors making real life experience acceptable Of course this does not replace good focusing and so the rangefinder coupling is quite welcome The second issue with the old lens was lack of front filter thread making it impossible to attach a filter to the lens On

  • Voigtlander Nokton 50mm f/1.1 (M) Lens Review
    its speed Nokton is a fairly chunky lens At 428g 1lb and 7 x 57mm 2 75 x 2 24in the lens is large and heavy in the world of Leica but can be considered compact among SLR users The optical construction of the lens consists of 7 elements in 6 groups As with all M mount lenses Nokton has a manual ffocus ring and a dedicated aperture ring The aperture ring clicks in half f stop increments with the minimum aperture of f 16 The minimum focusing is 1m and the lens accepts 58mm screw in type filters Voigtlander Nokton 50mm f 1 1 has a traditional M bayonet mount and can be used without any adapters on any modern as well as past generation Leica M cameras and their clones including obviously M8 M9 You can also use the lens on a number of modern mirror less cameras like Sony NEX and Micro Four Thirds cameras using special adapters Within the scope of this review the lens was tested on an APS H type Leica M8 giving an EFOV of 67mm Summary Lens Composition 7 elements in 6 groups Angular Field 46 degrees Minimum Focus 1m 5 9ft Focusing Action MF f stop Scale f 1 1 f 16 manual Filter Size 58mm Lens Hood Metal included Weight 428g 0 94lb Dimensions 70x57mm 2 75x2 24 Lens Case N A Handling Those of you familiar with the Voigtlander product line probably recall that prior to the f 1 1 version the company used to offer Nokton 50mm f 1 5 Aspherical in LTM mount This lens was very well regarded and while Cosina has discontinued this model in favor of the super fast f 1 1 version copies of Voigtlander Nokton 50mm f 1 5 Aspherical are quite popular on used markets and the prices for this lens don t seem to drop over time It s a pity that Cosina decided to completely discontinue that version and instead is now offering a limited edition Heliar 50mm f 2 effectively for twice the price of the original 50mm Nokton Of course an ultra fast 50mm lens is often a status symbol then anything else after all how many of us truly require an extra stop or two because we cannot achieve what we need by simply boosting an ISO level And so by offering an f 1 1 version Cosina might be trying to appeal not only to our ulter ego but also to our rational side that constantly nags us when we think about doing something bordering with crazy like spending 10 000 on that Noctilux Regardless whether you re craving for an affordable yes despite it s 1 000 price tag Nokton falls into affordable category in the otherwise overpriced Leica world in my opinion ulra fast glass because of the actual or imaginary need for that f 1 aperture you should realize that lenses of that speed are more about trade offs than anything else
