  • Carl Zeiss Distagon T* 28mm f/2 (C/Y) Lens Review
    has its limitations as you stop down the aperture of the lens less and less light gets through so by f 8 your camera s contrast based auto focusing system will simply give up and you would have to revert back to using stop down metering In general 28mm focal length is quite popular among photographers and is a natural step down towards the wide angle perspective that is from 35mm It gives users a wide enough field of view to photograph scenery or even architecture without worrying about significant amount of barrel distortion typically found in super wides like 21mm and 18mm Many will also find it much easier to compose their shots with a 28mm prime then with wider lenses since the latter ones give a significantly larger depth of field often requiring users to get really close to the subject or risk filling the frame with empty space Speaking of getting close to the subject Hollywood Distagon s floating optical formula is designed to improve image quality at close distances and given the lens s fast aperture and relatively small minimum focusing distance you get a very nice control over depth of field at close distances the shot below demonstrates how narrow the DOF can be at f 2 near the minimum focusing distance ISO 400 1 60 28mm f 2 Canon 5D The shallow DOF at f 2 can obviously be used for your advantage when trying to isolate a subject in focus from fore background The quality of bokeh out of focus areas plays a major factor in such situations and while the bokeh is often a matter of personal taste that is why we are trying to avoid calling bokeh outright good or bad generally speaking the shape and of out of focus highlights levels of contrast in the out of focus areas and existence of double edging around out of focus objects contribute quite a bit to the feel of the bokeh quality It is commonly accepted that well rounded and uniformly lit OOF highlights improve the look of bokeh while oval shaped highlights with harsh edges create a dizzying effect Image viewers also often prefer out of focus areas that have reduced amount of contrast that create a blending feel for OOF objects Obviously the existence of double edges around objects will also distract the viewer and thus are less desirable Based on these three evaluative criteria the 28mm f 2 Distgon is somewhat of an average performer the lens produced pretty severe edge outlining in OOF highlights as well as occasional double edging At least the contrast transitions in fore background areas were pretty neutral ISO 400 1 125 f 2 28mm Canon 5D The lens showed very good resistance to flare which can be observed in the shots below The sun in these cases was hitting the front element of the lens under 65 degree angle from the left hand side As you can notice both shots show generally reduced

    and border image quality was very solid in general a little bit of weakness at f 2 8 but still not disastrous and often not even noticeable in many frames Like any manual focus lens used on a non native body Carl Zeiss Distagon T 28mm f 2 8 was a pain to focus This is not necessarily the problem of the lens itself but rather a characteristic of most modern cameras Unlike the old times when SLR cameras had focusing screens that incorporated focusing aids i e a split circle majority of modern dSLRs have auto focusing systems and hence don t include screens suitable for manual focusing Combine that with often smaller viewfinders and the need to use stop down metering for using a non native lens and quite a few people might get repulsed by the whole idea of an alternative lens camera combination If you belong to such a group I d recommend getting an AF chipped adapter which would allow your camera to retain focusing confirmation You will still have to manual focus the lens but the camera s AF system will clearly indicate when the target object pops into focus Also keep in mind that because the lens offers a pretty large field of view small focusing errors are likely going to be masked I often used hyperfocal distance focusing with Carl Zeiss Distagon T 28mm f 2 8 and managed to achieve pretty good overall results although it s worth mentioning that this method will not necessarily produce the best results at close distances ISO 400 1 400 f 2 8 28mm Canon 5D Carl Zeiss Distagon T 28mm f 2 8 did not show any particular strength in bokeh handling OOF highlights were pretty harsh with well defined highlights around borders Contrast transitions around OOF objects were somewhat harsher then one would desire On a slightly positive note the lens did not exhibit any double edging around OOF objects Vignetting f 2 8 full frame vs 1 6x crop The lens produced moderate but noticeable amount of vignetting on a full frame Canon 5D at f 2 8 Wide angle lenses are prone to this artifact and Distagon T 28mm f 2 8 is not an exception here Vignetting still persists at f 4 albeit at at a lower level and by f 5 6 it is practically non existent Vignetting on an APS C camera was significantly lower at f 2 8 it was already minimal and at f 4 it was pretty much gone The lens held up very nicely against flare even at the widest aperture and did not show any major distortion Color rendition a playground typically dominated by Leica lenses was pretty accurate I literally did not see a single shot that required post processing color adjustment The lens produced images with good amount of contrast and well saturated textures Chromatic aberration where Zeiss lenses typically excel was not visible in most frames ISO 100 1 1000

  • Carl Zeiss Distagon T* 35mm f/1.4 (C/Y) Lens Review
    when Kyocera which was then its manufacturing partner and joint holder of Contax brand name exited camera business all together Carl Zeiss recently re introduced a number of its SLR lenses including Distagon T 35mm f 2 in Nikon Ai S ZF standard M42 screw ZS and Pentax K ZK mounts Despite the recently introduced newer 35mm lens the old C Y mount 35 1 4 Distagons remain in very high demand on used markets with good quality copies fetching US 1200 The lens was manufactured as an AE and later MM variant both in Japan as well as in the West Germany Thus you can encounter a total of four different variations of this lens an AE copy made in the West Germany or Japan and an MM copy made in Japan or West Germany There does not seem to be any optical changes between the AE and MM versions of the lens at least according to the publicly available sources The optical construction of the lens consists of 9 elements in 8 groups including a single aspherical element and a single floating element designed to correct various forms of aberration at close distances The build quality of the lens is superb and is similar to other Carl Zeiss lenses of that period for Contax mount all metal barrel rubberized focusing and aperture rings The focus ring is very smooth the aperture ring is snappy and there is no wobbling of any sort inside or outside the lens And like all Carl Zeiss Contax lenses Distagon T 35mm f 1 4 is a fully manual lens meaning that there are no electronics of any sort in the lens and both focusing and aperture have to be set on the lens rather then through your camera Speaking of the aperture

    f 16 Filter diameter is 72mm Within the scope of this review the lens was tested on a full frame Canon 5D Mk2 I am currently replacing my aged APS C camera and will conduct additional tests on an APS C body at a later point As a reminder on an APS C type body with 1 6x crop factor Distagon will have EFOV of 56mm lens The manufacturer s box includes the lens front and rear lens caps lens hood registration and quality control cards along with a manual book Summary Lens Composition 11 elements in 9 groups Angular Field 64 degrees Minimum Focus 30cm 11 8in Focusing Action MF f stop Scale f 1 4 f 16 electronic Filter Size 72mm Lens Hood Metal included Weight 830g 1 8lb Dimensions 78x119mm 3 07x4 72 Lens Case N A Handling The new 35 1 4 version of the lens is the direct descendant of Diistagon 35 1 4 originally launched in 70s under Rollei mount and later continued through 2005 in Contax mount I never owned a Rollei version but based on the data sheet I believe that the only difference between the Rollei and Contax versions is coating I owned two versions of Contax lens first in my film days and later adapted to my Canon mount using a third party adapter Truth be told Contax Distagon 35 1 4 was never my favorite lens I found it too finicky and inconsistent particularly at wide apertures where the resolution as well as rendering were not what I was looking for in a high speed lens To be fair I can t say whether this was due to the lens itself or the adapter added some variance but either way I ended up selling the Contax 35 1 4 and switching to Nikon mount ZF 35 2 version which I found much more consistent ISO 800 1 80 f 1 4 35mm Canon 5DMk2 Comparing the data sheets of the new ZEZF 2 version to the Contax variant it becomes clear that Zeiss has tweaked the design quite extensively The optical contraction has become more complex 11 elements in 9 groups vs 9 elements in 8 groups Both lenses have single aspherical element as well as floating groups but due to the increased number of groups elements ZE ZF 2 version is bulkier and heavier Still I welcome the native mount version since I no longer need to fuss with various adapters Plus considering the recent prices for Contax version have climbed to astronomical levels used copies sell for US 1 500 1 600 on eBay now there is very little reason to own the old variant With the release of the ZE ZF 2 351 4 version Carl Zeiss entered a fairly crowded and competitive market It is not clear to me yet whether the Distagon holds a definitive advantage over say Canon 35 1 4L and Nikon 35 1 4G since I have not compared these lenses

    ZF for Nikon F ZS for M42 universal screw and ZK for Pentax K Carl Zeiss selected Cosina of Japan to manufacture its new lineup of SLR lenses Cosina is predominantly known for its line of excellent Voigtlander SLR and rangefinder lenses New copies of the lens are sold for US 850 as of April 2008 at online photography retailers like B H Photo The newly released version of Distagon T 35mm f 2 incorporates a redesigned optical formula of the older Distagon T 35mm f 1 4 the optical construction consists of 9 elements in 7 groups instead of 9 elements in 8 groups If you examine the optical designs side by side you will also notice that the element configuration has also changed Hopefully all these changes are going to improve the overall optical characteristics of the lens The physical dimensions of the new Distagon also changed at 65 x 73mm 2 55 x 2 87in and 520g 1 16lb the lens is slightly narrower smaller and lighter then its older f 1 4 variant The build quality is as solid as ever no plastic no rubber the barrel cams aperture and focus rings even the lens hood are all metal The lens carries that aura of German excellency it looks and feels very sturdy with no wobbling inside or out very smooth focus ring and snappy aperture ring which rotates in half f stop increments Bottom line is that Carl Zeiss did not skimp on the quality here As all other lenses in its ZF ZS ZK lineup Carl Zeiss Distagon T 35mm f 2 is a fully manual lens so there s no electronic coupling on the base of the lens mount to control the aperture or focusing This unfortunately limits its usage on consumer grade

    f 2 8 The Contax series were discontinued back in 2005 after Kyocer a joint holder of the development rights on Contax brand name exited camera business Carl Zeiss still retains control over the Contax brand but due to some legal restrictions cannot yet reintroduce any products branded under Contax name to the market as of 2008 Fortunately the company recently started to offer a number of its renowned SLR lenses for a few 3rd party mounts including Nikon F Pentax K and M42 universal screw The new lineup along with resurrected 25mm and 28mm primes also includes a revised 35mm version Carl Zeiss Distagon T 35mm f 2 The Contax version of Carl Zeiss Distagon T 35mm f 2 8 is one of the most affordable lenses with good quality copies of the lens typically going for US 200 on eBay as of April 2007 Compare that to the price of US 800 for its slightly wider cousin Distagon T 35mm f 1 4 also in Contax mount or to the price of US 900 for the new version of the lens in Nikon F ZF or Pentax ZK mounts Like its wider f 2 8 cousins Carl Zeiss Distagon T 35mm f 2 8 sports an excellent build construction the barrel is fully metal and both aperture as well as focusing rings are rubberized for comfortable grip The focusing ring is very smooth and the aperture ring snaps in into positions very nicely even requiring a little bit of pressure There is no play with the aperture focus rings Despite its lightweight construction the lens measures only 62 5 x 46mm 2 4 x 1 8in and weighs 250g 8 6oz the lens leaves impression of being quite sturdy with no wobbling inside or out The optical construction

    the new T coating vs the old HFT one used on Rollei lenses The lens was exclusively manufactured in West Germany at Zeiss factories and was only available as AE variant Unfortunately the design did not survive for long in the Contax mount either as the system was discontinued after Kyocera which leased the brand name from Zeiss pulled out of the camera market all together in 2005 But the hope is alive since Carl Zeiss has recently re introduced a number of its SLR lenses for Nikon Pentax and even Canon mounts Hopefully Zeiss will eventually bring back the F Distagon lens as well The F Distagon was never the most popular lens even during its mass production Has something to do with being a fish eye not that many users can utilize a lens with the angular field of 180 degrees in their day to day photography These days a limited number of samples can be regularly found on eBay with prices ranging from US 1 000 to US 1 500 depending on the condition The lens is a great example of German optical engineering at its best pretty much like with most Contax lenses of that era The lens is solidly built with metal barrel and rubberized focusing and aperture rings that are well damped The aperture ring moves from f 2 8 through f 22 in one full f stop increments there is a little bit of resistance as you click from one aperture setting to the other which adds to the feeling of quality For a super wide angle lens F Distagon T 16mm f 2 8 is pretty compact and light measuring 70 x 61mm 2 75 x 2 4in and weighing 460g 1lb The lens focuses down to 30cm 1ft The optical formula
