  • Nikon AF Nikkor 50mm f/1.4D Lens Review
    to allow the in camera screw drive control the focusing by moving the lens elements in and out of focus until the camera s AF confirmation catches the focus Since the lens does not have a built in motor the AF system performance mostly depends on the camera itself At least on Nikon D3 focusing was more or less smooth I say more or less because once in a while the focusing system hunted back and forth before settling in a position And unlike silent ultra sonic motors found in many modern lenses AF D lenses focus with a pretty loud noise there s a distinct vzhiiik that can be heard every time the camera screw drive rotates in lens mechanics However the fact that AF D lenses were designed to be fully backward compatible and therefore retain manual focusing as well as aperture control rings makes the AF Nikkor 50mm f 1 4D a good candidate for adoption to alternative mounts Naturally when used as an alternative lens on say a Canon SLR you would loose both AF functionality as well as automatic aperture control And while AF Nikkor 50mm f 1 4D is a pretty bright lens you should still consider investing in an AF confirmation adapter or at least a focusing screen to make focusing easier Performance wise AF Nikkor 50mm f 1 4 showed rather mixed performance in the field The lens performed quite poorly at wider apertures particularly at f 1 4 on both full frame as well as APS C cameras where both center as well as borders were noticeably soft Image quality did improve by f 2 8 and from that level on remained quite good with no major visible difference between the center and borders ISO 400 1 250 f 1 4 50mm Nikon D3 When shot with wide open aperture the lens produced well rounded out of focus highlights that carried sharply defined outlines typical of lenses with over correction for spherical aberration On the positive side there was no sign of double edging around OOF objects and contrast transitions in near far OOF areas were pretty smooth Vignetting f 1 4 full frame vs 1 6x crop The lens showed pretty noticeable vignetting on a full frame camera at f 1 4 Light falloff was still quite noticeable at f 2 and even f 2 8 finally disappearing around f 4 The lens behaved much better on an APS C showing only minimal traces of vignetting at f 1 4 which were pretty much gone by f 2 8 Regretfully the lens fell prone to pretty heavy flare at wider apertures with strong direct light sources positioned in or near the picture frame In the shots below sun rays were hitting the lens at 45 degree angle As can be seen from the shots the lens produced both flare as well as ghosting at f 1 4 Flare greatly reduced contrast across the entire frame However amount of flare was greatly reduced with stopped down aperture and at f 8 flare while still visible did not cause as much damage as with wide open aperture Top ISO 200 1 8000 f 1 4 Bottom ISO 200 1 2500 f 8 Nikon D3 Color reproduction was also a mixed bag At wider apertures particularlyat f 1 4 the lens produced images with somewhat washed out colors A significant contributing factor here was the lens pretty low resolution across the entire frame which obviously also reduces the amount of contrast making the pictures look lifeless Things actually improve quite drastically around f 2 8 with both color and contrast returning to pretty normal levels Other then that the lens showcased good handling of color fringing including axial CA ISO 200 1 8000 f 1 4 50mm 100 crop Title Title Title Title Title Title Title View the embedded image gallery online at http slrlensreview com web reviews nikon

somewhat mixed performance on a full frame Nikon D3 The lens shows clear weakness at wider apertures where both center as well as border performance are pretty dismal Image quality steadily improves with stopped down aperture but center performance does not reach solid levels until f 2 8 and border image quality does get a good boost until about f 4 From f 4 through the rest of the aperture image quality remains excellent across the entire frame Performance in this range actually remains well balanced with no major gaps between the image center and borders Conclusion Disappointing performance at f 1 4 and f 2 in general and somewhat disappointing border performance at f 2 8 It is in general expected that ultra fast lenses will show some border weakness at widest apertures but AF Nikkor 50mm f 1 4D does not impress even at f 2 8 which is rather hard to swallow Normalized raw MTF50 50mm The lens showed pretty minimal levels of chromatic aberration in the center where CA never exceeded 0 3px CA around borders was slightly higher but even there it never exceeded 0 7px across the entire tested aperture range So it should not be a major issue in general Chromatic Aberration FF 50mm

  • Nikon AF-S Nikkor 50mm f/1.4G Lens Review
    the lens which was fully backward compatible with pretty much all Nikon bodies dating back to 70s Nikon decided to limit the compatibility in favor of incorporating some of the newest technologies the company invented While Nikon currently offers both the older AF D as well as the new AF S versions of f 1 4 lens it is widely expected that the company will quietly drop the old design in the coming months The AF S Nikkor 50mm f 1 4G is widely available from camera and lens retailers and sells for US 450 as of November 2009 The optical construction of the lens consists of 8 elements in 7 groups The build quality of the lens is decent but particularly special the barrel is plastic and while does not leave you with a cheapo feel it s a step backwards compared to the old all metal designs of the past Nikkors The lens is fairly compact and light measuring 73 5 x 54 2mm 2 9 x 2 1in and weighing 280g 9 9oz According to Nikon site the lens does not sport inner focusing since the lens groups slide back and forth during focusing however the overall length of the barrel does not change at all The lens sports the new AF S type auto focusing system with Silent Wave Motor don t you love these abbreviations although manual focusing is also possible using the dedicated focusing ring The AF MF switch on the side of the barrel allows you to disable the AF S motor in the lens but you can achieve that by switching your body into manual focusing mode as well One major change in the new version is the fully electronic aperture which is denoted by the letter G on the lens This

    still performed by the camera driven ping which locks into the dedicated screw slot on the base of the lens mount And while AF works and works more or less fine it was pretty accurate in most situations the speed with which the lens is focused leaves a huge room for improvement Furthermore the lens is quite noisy and the worst part is that it s noisy not only during AF operation but also during manual focusing It is as if the internal elements are rubbing against the inner walls of the barrel or something This should not necessarily be the deal breaker for majority of photographers but in the modern age of ultra sonic motors the pin operated AF seems pretty archaic Nikon AF Nikkor 180mm f 2 8D ED IF very good overall results in the field Images remained tack sharp throughout the aperture range both in the center as well as around borders at least visually there was no noticeable difference between the center and borders Furthermore the lens showcased pretty consistent results on APS C as well as full frame bodies which is quite remarkable Vignetting f 4 5 Full frame vs 1 6x crop The lens showed moderate level of vignetting at f 2 8 on a full frame body The degree of vignetting is reduced further with stopped down aperture and by f 5 6 it completely disappears On an APS C body the lens shows insignificant amount of vignetting even with wide open aperture and basically no vignetting from f 4 and on Those of you using Nikon D3 or any other body with an in camera vignetting correction can easily get rid of this artifact by simply selecting one of the pre programmed modes Otherwise just use a post processing software The lens showed very good resistance to flare Even in situations with a strong light source placed directly within the picture frame the flare caused only relatively minor reduction in contrast blown out highlights and some traces of vailing as can be seen from the image below All in all not that bad ISO 200 1 500 f 8 180mm Nikon D3 General color reproduction was quite good with images carrying good amount of contrast throughout the aperture range Colors were well saturated and textured looked very vivid and lifelike There was no visible sign of color fringing As expected from a telephoto prime AF Nikkor 180mm f 2 8D ED IF did not exhibit any noticeable barrel distortion ISO 200 1 6400 f 2 8 180mm 100 crop Title Title Title Title Title Title Title Title Title View the embedded image gallery online at http slrlensreview com web reviews nikon super telephoto 106 nikon af nikkor 180mm f28d ed if lens review sigProGalleria290c0d63b9 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

    adapter was used when testing the lens on Canon bodies Summary Lens Composition 9 elements in 8 groups Angular Field 28 degrees Minimum Focus 85cm 2 8ft Focusing Action AF MF f stop Scale f 1 4 f 16 camera manual Filter Size 77mm Lens Hood NH 31 included Weight 550g 19 8oz Dimensions 80x72 5mm 3 1x2 9 Lens Case CL 44 optional Field Tests The first thing you will notice after screwing Nikon AF Nikkor 85mm f 1 4D to your camera is that the lens is pretty bulky The front element of the lens is simply humongous making the relatively large camera like Nikon D3 look a little bit dwarfish And on a small APS C camera like Canon Digital Rebel XTi the lens looks and feels like Gulliver in the land of Lilliputian Not that the lens is huge by all standards there are certainly bulkier heavier and larger medium telephoto lenses out there but AF Nikkor 85mm f 1 4D is certainly not a very discreet lens that can be used say in street photography The bulkiness of the lens brings some other disadvantages as well The aperture ring is located pretty close to the rear end of the mount and is well recessed making it a little bit hard to get grip on and rotate between positions And if you have the ring locked at f 16 for electronic aperture control you will literally need to use the tip of your fingernail to unlock it As mentioned above Nikon AF Nikkor 85mm f 1 4D supports both manual as well as automatic focusing and aperture control This makes the lens a good candidate for adaptation to alternative mount cameras such as Canon EF EF S and Olympus 4 3 Naturally when used on an alternative camera you d loose AF as well as some advanced features like 3D Matrix metering so you should be comfortable with manual focusing Buying an AF confirmation adapter in general is going to be a good investment but keep in mind that even with an AF adapter you will have to rely on stop down metering quite often Since you will be stopping the aperture manually the camera s viewfinder will get darker and darker at smaller aperture levels and your camera s AF confirmation will pretty much give up around f 5 6 At this aperture level the viewfinder is typically dark enough to make pure manual focusing practically impossible Hence you would likely have to focus the lens wide open get the AF confirmation and then stop down the lens to the desired aperture Not the most streamlined process but that s the cost of using alternative lenses But enough about the looks and feels let s look at how the lens performed The lens showcased pretty good overall performance in the field Images were uniformly sharp from about f 4 through the rest of the aperture range on both full frame as well as APS C cameras There might have been some minor differences between the border and center performance but visually quality was about the same The story was a little bit different at wider apertures Here the lens showed a marginally better image quality on an APS C camera but overall both center image quality and to a larger degree border image quality were noticeably softer f 2 8 seemed to be a transitional point with this lens quite good results in the center but still a bit soft edges Furthermore image quality seemed to suffer a little bit more at close distances wider apertures seemed to be more prone to that then smaller for example compare the shot with a yellow rose which was taken at the closest distance of 85cm to other images taken with wide open aperture at infinity ISO 400 1 200 f 1 4 85mm Nikon D3 When shot with wide open aperture the lens produced well rounded and mostly uniformly lit out of focus highlights OOF edges were predominantly neutral although in a few cases you could spot slightly harsher edge highlighting The lens also produced occasional color fringing in OOF highlights which can be noticed in the image above as well as in the wine glass shot in the image gallery Contrast transitions in near far OOF areas were pretty smooth which helped to better isolate the in focus targets There was no sign of double edging around OOF objects Vignetting f 1 4 full frame vs 1 6x crop The lens showed noticeable vignetting on a full frame camera at f 1 4 Not a big surprise here though since majority of fast primes produce some vignetting wide open Vignetting is reduced with stopped down aperture but does not completely go away until about f 4 On an APS C camera the lens takes advantage of a reduced image sensor but still shows minor vignetting at f 1 4 which practically disappears by f 2 8 AF Nikkor 85mm f 1 4D showcased very good practically neutral color reproduction images in general carried good amount of contrast throughout the aperture range and colors were sufficiently saturated which in turn helped create rich life like textures All good and dandy but unfortunately the lens fell prone to pretty severe flare at wider apertures At f 1 4 the lens showed flare in situations with a direct light source located within or close to the frame Same was true with surface reflected light as can be seen in the shot below In all these cases flare manifested itself as greatly reduced contrast and blown out highlights ISO 400 1 8000 f 1

  • Nikon AF Nikkor 85mm f/1.8D Lens Review
    When it comes down to handling AF Nikkor 85mm f 1 8D behaves pretty much like any other medium telephoto lens out there Pretty much There are two notable exceptions worth mentioning here Firstly unlike lenses from its main rival Canon all AF D lenses including AF Nikkor 85mm f 1 8D supports both manual as well as electronic in camera control As mentioned in the overview section the lens sports dedicated focusing and aperture rings which provide full control over the lens You might ask why this matters so much Well the major reason for excitement here is that with a fully manual aperture and focus controls the lens becomes a great candidate for adaption to an alternative mount Namely to any Canon EF EF S system or even any 4 3 system Granted after adaption you would naturally loose not only auto focusing and electronic aperture control but also any advanced feature such as 3D Matrix Metering Still if you don t shy the idea of finding a great piece of optics even if it means operating it manually then AF Nikkor 85mm f 1 8D as well as any other AF D Nikkor is the lens to explore The second issue worth mentioning here is the AF system of the lens Back in the day when Nikon was upgrading its Ai series of lenses the company decided to implement AF using a purely mechanical system partly to keep the costs down partly to keep backward compatibility with thousands of non Ai Ai D Ai and Ai S lenses out there The resulting AF system might have been considered good back then but is totally outdated in the modern day and age requiring replacement sooner rather then later The AF operations on 85mm f 1 8D are just noisy and slow when compared to the modern ultra sonic AFs Speaking of manual focusing While the lens offers a dedicated focusing ring precise focusing is not necessarily as easy as with some dedicated manual focus lenses of old time This is simply due to the relatively short distance the focusing ring has to travel the ring rotates about 100 degrees when going from the closeup of 85cm to the infinity with slightly more spacing allowed for in the shorter focus range Compare this to 270 360 degree rotations implemented in some fully manual lenses And unlike with wide angle lenses focusing errors are not going to be masked here due to a relatively narrow field of view Moving on Nikon AF Nikkor 85mm f 1 8D showed very solid overall performance in the field The lens showed excellent resolving capacity at moderate and small aperture levels f 8 through f 11 seemed to be the best range for the lens Images here remained sharp across the entire picture frame at least visually there was no noticeable degradation in image quality Wider aperture settings especially f 1 8 were somewhat of a mixed bag Here the lens seemed to struggle a little bit showcasing some softness both in the center as well as around borders Furthermore the lens seemed to perform slightly worse at close distances then at infinity that was more noticeable at wider apertures then at smaller ones making f 1 8 pretty challenging at closeup distances For example compare center image sharpness of flower and music band pictures in the image gallery Both were taken at f 1 8 but at different distances flowers were shot at 85cm while the music band was shot at infinity both were shot with an AF enabled ISO 400 1 160 f 1 8 85mm Nikon D3 When shot at f 1 8 the lens produced well rounded uniformly lit out of focus highlights which often carried harsh edge outlining common issue in lenses with over correction for spherical aberration The effect might become too distracting in some situations affecting the picture s feel of bokeh On a positive side there was no sign of double edging around OOF objects and contrast transitions in near and far OOF areas were pretty smooth which generally helped isolate in focus targets Vignetting f 1 8 full frame vs 1 6x crop The lens showcases pretty heavy vignetting at f 1 8 on a full frame camera which continues to persist at f 2 8 and even f 4 albeit in lower amount Once stopped down to f 5 6 vignetting is completely gone On an APS C camera the lens takes full advantage of the smaller sensor with reduced image circle coverage and shows very minimal amount of vignetting at f 1 8 and practically no vignetting at f 2 8 and beyond In general vignetting is relatively easy to correct during post processing and some modern cameras like Nikon D3 even offer an in camera correction just select one of the pre programmed levels to activate the correction Nikon AF Nikkor 85mm f 1 8D fell prone to occasional flare the amount of which varied in different situations At wide apertures the lens showed pretty heavy reflective flare shown in the image below as well as veiling flare which greatly reduced overall image contrast with the lens pointed up to 45 degree angle towards a direct light source However at smaller apertures f 8 f 16 the amount of flare and aperture ghosting were quite low even with a light source directly in the frame Obviously you can reduce the amount of flare by using a lens hood or by simply composing your image in a different manner just be aware of this weakness ISO 400 1 8000 f 1 8 85mm Nikon D3 General color reproduction was quite good images at wider aperture settings from f 1 8 through f 2 8 showed slightly lower amount of contrast then at smaller apertures and exhibited minor amounts of axial CA which can be seen in the flower shot in the image gallery But once stopped down to f 5 6 or f
