Nikon AF-S FISHEYE NIKKOR 8-15mm f/3.5-4.5E ED F/4.5-29 Fixed Zoom Camera Lens, Black
Inside and out
The Nikon 8-15mm f3.5-4.5E ED fisheye is a 1.9x too wide-point zoom. It has an edge of perspective on 180 degrees and undertakings a round picture at 8mm on a full-outline sensor, totally covers a DX-sensor at 11mm, and totally covers a full-outline sensor at 15mm. So this zoom covers viably three separate fixed-central fisheye focal points. The main thing you can't do with it is to extend a roundabout picture on a DX-sensor: for that you'd need a 5.5mm fisheye focal point. Reported in April 2017, it fills a hole in Nikon's arrangement of focal points as up to now Nikon just offers its 10.5/2.8G DX fisheye and the 16/2.8D FX fisheye. Nikon furnished its new focal point with an electromagnetic stomach instrument, nano precious stone coat in addition to fluorine covering on the front and back focal point components for simpler cleaning, and furthermore solidified the focal point barrel with extra fixing against residue and dampness. This makes the gold-ringed focal point fit Nikon's line-up of expert focal points and they charge as needs be: 1250 USD/1500 EUR is the rundown cost for this new zoom.To discover how the new Nikon 8-15mm f3.5-4.5E ED fisheye performs I tried it against Nikon's own 10.5/2.8G DX and 16/2.8D fisheye focal points in addition to Tokina's AT-X 10-17/3.5-4.5 AF DX NH fisheye on the requesting D810 body. So in case you're looking for a fisheye focal point, you've gone to the opportune spot!
Realities from the inventory
As regular I'll view the specialized information first. I've appraised the highlights with a [+] (or [++]), when it's superior to average or even best in class, a [0] if it's norm or simply normal, and [-] if there's a drawback. I'll contrast it generally and Nikon's just other full-outline fisheye, the 16/2.8D.Size (diam. x length): 78 x 83mm (3.1 x 3.3in) without focal point hood at its most limited length which is at 10mm central length. This is good enough for an advanced focal point. The focal point hood includes another 11mm long and has a measurement of 96mm. The old 16/2.8D fixed central is a lot littler at 57 x 63mm with focal point hood. [0]
Weight: 485g (17.1oz.). The 16/2.8D is 290g. [0]
Optics: 15 components in 13 gatherings which is considerably more than the 8/5 of the 16/2.8D. Be that as it may, that focal point isn't a zoom. The new focal point has three (extra) low scattering and two aspherical components. Nano covering ought to lessen flare and ghosting. [+]
Nearest center separation/max. amplification: 0.16m (0.52ft)/1:2.9 (at 15mm central length) contrasted with 0.25m (0.82ft)/1:10 with the 16/2.8D. The greatest amplification of the new Nikon is very acceptable however you just have around 3cm of working separation. An amplification of 1:10 is accomplished at around 0.27m separation which gives 14cm working separation. [+]
Channel string: None of the fisheye focal points (or any ultra wide-edge zooms from Nikon, Tamron, Sigma or Group besides) offer a channel string. Their bulbous front components forestall that. Be that as it may, you can embed 27x29mm gel-channels in an opening over the back focal point component. See next photograph. The Nikon 10.5/2.8G has a comparable opening and the 16/2.8D offers an uncommon kind of screw-in channel over the back focal point component. [+]
Picture Adjustment: No fisheye focal point has picture adjustment. [0]
Auto Center: HSM (Hyper Sonic Engine), so it likewise takes a shot at camera bodies which don't have an AF-drive worked in like Nikon's D3x00/5×00. Manual-center abrogate is by basically turning the center ring. All the choices from Nikon and Tokina need a center engine in camera to drive the AF. [+]
Covers full edge/FX or littler = generally excellent. As does the 16/2.8D. [+]
Cost: around 1250 USD/1500 EUR (incl. 19% Tank), 100% more costly than the 16/2.8D which can be had for around 750 EUR. Be that as it may, to put the cost of the new Nikon in context: The Standard 8-15/4.0 L fisheye as of now sells at around 1200 EUR. [0]
Accompanies a standard delicate case. The focal point hood has an interlock to forestall unplanned misfortune. It tends to be evacuated and ought to be the point at which you're shooting round pictures on a full edge sensor underneath 14mm central length. The front focal point top captures set up when mounted on the focal point hood (see next photograph) – excellent! At the point when you utilize the implicit blaze the shadow of the focal point (even without hood) is consistently noticeable at the base of the picture at any central length on a FF-/FX sensor. In the event that you yield to APS-C/DX position the shadow is marginally noticeable at a central length of 11mm and turns out to be progressively articulated at shorter central lengths. The locally available blaze of the D810 can fill the DX outline at 15mm central length moderately well yet shows substantial vignetting at 12mm and shorter central lengths. [0]
Separation data is handed-off to the camera, so the Nikon body can do all the propelled introduction related stuff with this focal point. Same with the opposition. [+]
Gap ring: no. The 16/2.8D has one. [0]
Fixing: An elastic grommet at the focal point mount and more in the focal point barrel. [+]
The score in the "highlights division" is 0[-]/6[0]/7[+]. This is quite acceptable with no genuine drawback.
Here is the thing that the 8-15mm zoom ventures on the sensor:
On a full-outline sensor the point of view is consistently around 180 degrees paying little mind to the central length you use while on a DX sensor the edge of view limits from 180 degrees at central lengths somewhere in the range of 8mm and 10mm to 110 degrees at 15mm.
Following is the inclusion of the Nikon 10.5/2.8G (with sawn-off focal point hood to produce a roundabout picture) and the Nikon 16/2.8D:
Furthermore, in the event that you wonder how a "straight" 15mm focal point would catch a similar scene following is a picture from the Tamron 15-30/2.8 VC at 15mm:
Choices
There is just a single other fisheye zoom accessible for Nikon (and Ordinance) bodies: The Tokina AT-X 10-17mm f3.5-4.5 AF DX. It is assigned as a focal point for APS-C/DX-sensors however my tests indicated that it covers full-outline sensors well at central lengths of 14mm and more. In case you're utilizing it on a full-outline body you ought to get the "NH" form which has no hood. This takes into account round pictures though with 29mm width at 10mm central length which get's cut off at the top and base by the sensor. See the accompanying pictures:- Nikon up to now just offered two fixed central focal points with fisheye trademark: the AF DX 10.5mm f2.8G and the AF 16mm f2.8D. Know however that the two focal points need a body with incorporated AF engine to auto-center.
- Ordinance clients can get the EF 8-15mm f4.0 L USM from 2010. It has a road cost around 1200 USD/EUR and was tried as sharp in the middle. Yet, it mollifies uniquely towards the corners and displays some solid horizontal shading abnormalities when utilized fully open. What's more, obviously it can't be adjusted to Nikon DSLRs. See Gordon's Ordinance 8-15/4.0L fisheye audit.
- Sony clients don't have a fisheye zoom for E (or A) mount however can get a great deal of fixed central fisheyes generally from Samyang/Walimex and the Sony 16/2.8 for A mount. Be that as it may, with the assistance of the suitable connector either the Group or the Nikon 8-15mm zoom can be utilized on Sony E-mount bodies.
Fokus
Center exactness and repeatability is basic to reliably create sharp shots. Repeatability (the exactness of spotlight on a similar subject after rehashed center obtaining) of this focal point is generally excellent (estimated 99.1% in Reikan Central) without any anomalies over a progression of 40 shots under carefully controlled test conditions. Also, there is without a doubt, almost no presentation variety whether the focal point centers from endlessness or from a closer separation.At 15mm central length the focal point centers with no chasing in around 0.3 sec from limitlessness to 0.27m, which is quick. The center ring has no leeway/play between its development and the center activity and a toss of 55 degrees which is adequate for manual concentrate fully open. Its rubber treated surface is 10mm wide and can be turned with one finger. The zoom ring turns through 60 degrees and has a 14mm wide elastic surface and can likewise be turned with one finger. Nikon put the zoom ring at the front of the focal point and the center ring behind that.
AF-activity is tranquil all things considered, and in the event that you record video with the inherent receiver the AF-drive delivers a slight murmur and just black out snaps toward the beginning or stop of center developments.
As you pull center, you'll notice some center breathing: the picture turns out to be less amplified at nearer centering separations. At the point when I balanced the concentration from interminability to 0.27m, I estimated a 1-2% decline in amplification at 8mm and 15mm central length which is negligible and ought not demonstrate diverting when shooting video. Next look at my quality outcomes and test pictures!
