Đánh giá lens 80-400 nikon năm 2024
I have used this lens extensively, plus similar alternatives like 300F4+1.4tc and 200-500 and 70-200F2.8. Personally, I use the lens mostly as a travel lens instead of the 70-200F2.8. Both lenses are about the same size. Because for travel, the extra focal length is far more useful than F2.8. But that's travel, almost always outdoors. Let's look at the good stuff with the 80-400g: light weight and small-ish size (about the same as 70-200), fast AF, good zoom rate (far superior to the 200-500), and excellent performance optically from 80 to about 320-350mm. Decent enough at 400mm if not shooting birds and cropping. 80-400 is versatile alright, fast focusing too, but I've been trying hard to love it and just can't. The problem is, if I'm lugging a 400mm lens I would want it to be reliably good at 400mm, while this lens, my sample at least, requires stopping down at 400mm for very good sharpness on a high MP camera. Quite brilliant at 400/5.6 on a D3S, not quite as much on a D810, and not really fully acceptable IMO on a D7200. You also call it lightweight, which I wouldn't. It sure is lightweight compared to 200-400/4, but not to something like 70-300, -- which is what I would call lightweight for travel. Perhaps my endurance levels aren't what they should be, but I'm really having second thoughts about travelling with it unless I know in advance I would likely regret not having it. I don't know how 80-400 compares to 200-500 since I've never had one, but it doesn't come close to the Sigma 60-600 Sport. Crazy, right, a 10x zoom that is very sharp at 600mm wide open, even on a 24MP DX sensor. Sure, it is also a whole lot heavier than the 80-400, so not a travel lens at all unless for something like a safari. I hardly ever use my 70-200F2.8 anymore - maybe once a year. For me, someone who has a pretty good collection of lenses, each lens I have is a specialty lens. The 70-200F2.8 is really an event lens, perhaps even an 'indoor event lens', where events are sports or concerts and the like. I agree, 70-200/2.8 isn't a walkabout lens, nor is it a very convenient travel lens, 70-200/4 is much handier in this regard. But for events 70-200/2.8 is perfect, and not shabby for portraits either. THIS (70-200F2.8) is what you need for indoor anything sports. Depends on "anything". If it is a large enough space, 120-300/2.8 would be a better option. Doesn't have to be the insanely expensive Nikkor, Sigma's Sport model is excellent too. In addition, it works perfectly with the Sigma 1.4x TC, so could be used for outdoor sports in in lieu of 200-400/4, and would be nearly as good (or maybe better?) It does have a drawback as compared to 70-200/2.8, it is much heavier, and while 70-200/2.8 is easily hand-holdable, 120-300/2.8 really needs a monopod for support. The 80-400g is at least a stop slower in a scenario where those stops mean a great deal, partly to isolate the subject from a background. Outdoors, the 80-400g is a pretty good choice for football on a D3s. A 300F2.8 is often seen as a 'more perfect' lens for football, but (I think) mostly when that football takes place at night. And at night you'll have issues with the 80-400g, so perhaps a 70-200F2.8 coupled with a 300F4 might be a better choice. For daytime outdoor sports, 200-400/4 is probably the best, or at least most flexible option overall (or 120-300 + TC as mentioned), but 200-400 is big, long, and heavy, so needs support. On the other hand, 80-400 would work fine for outdoor daytime sports too, AF is fast enough, it just won't give you the subject isolation you can get with a constant f/4. (From Nikon lens literature) Result of VR (Vibration Reduction) is equivalent to using a shutter speed three f/stops faster. VR is automatically detected during panning operation. Two modes of VR: Image plane and Viewfinder. 3 ED glass for high resolution and high contrast even at maximum apertures. Filter does not rotate during zooming. Test Notes This lens joined Nikon's lineup a few years back (2001?), and continues to be popular with long-zoom aficionados. It combines an impressive 5x telephoto zoom range with Nikon's VR (Vibration Reduction, aka image stabilization) technology to permit hand-holding of long-telephoto exposures under less than ideal lighting. Sharpness At the shorter end of its range, this lens is pretty sharp wide open, with a nice uniformity across the focal plane. It gets progressively softer as you zoom to longer focal lengths though, and is quite soft at 400mm and f/5.6. Stopping down to f/8 helps matters somewhat, but there's still some softness, and the blur profile of our test sample was a little high on the left side. Diffraction limiting began to be a factor around f/16 with our D200 test body. At 80mm, the minimum aperture of f/32 results in somewhat soft images, but not as bad as we're accustomed to seeing at that aperture. At 400mm, f/32 is much softer, and the minimum f/40 is so soft that that aperture is really only good for soft-focus special-effects shots. Chromatic Aberration Chromatic aberration on the 80-400 VR is a bit of a wild ride, ranging from excellent to poor, depending on focal length and aperture. At its shorter focal lengths (80-135, a bit less so at 200mm), chromatic aberration is rather high wide open, but drops dramatically as you stop down: CA is moderate at f/8 and excellent by f/11. As you move out to 300 and 400mm though, maximum CA gets rather high, regardless of aperture, while average CA remains moderate. Shading ("Vignetting") Exposure uniformity is one of this lens' real strong points (at least on a sub-frame SLR like the D200). Exposure across the frame is uniform to within better than 1/4 EV at all focal lengths and apertures, and 1/8 EV or less when stopped down one stop from maximum aperture. Distortion Distortion is also quite low on this lens, ranging from slight barrel (~0.29%) to slight pincushion (~0.28%) at 80 and 400mm, respectively. Focus Operation The 80-400mm VR doesn't focus terribly fast: There's a lot of glass in there to move around, so it takes a while to slew from far to near or vice versa. (I'd estimate somewhere on the order of 2 or 3 seconds to move from infinity to minimum focus.) Manual focusing is smooth, with plenty of travel on the focus ring to make precise adjustments easier. The change between manual and automatic focusing is accomplished with a locking, slightly stiff ring on the lens body, located between the zoom and focus rings. Like most lens with conventional (vs ultrasonic) motors, you must switch the lens from auto to manual in order to use the manual focus ring. The good news though, is that you can just grab the ring and turn it to make the switch, without having to unlock it first. It does have a locked position for both manual and automatic though, so you can choose to either have it lock or not, as you prefer. The lock ring on our test sample was rather stiff, but worked OK. Image Stabilization I'm a real fan of image-stabilized lenses, they can make a huge difference in the number of sharp shots you can bring back under difficult lighting situations. In the case of the 80-400VR, I found that it's VR system worked best at damping out fairly large amounts of shake at slightly higher shutter speeds, but if I was close to being able to get a steady shot on my own, I was better off turning the VR system off. I played with the lens extensively indoors, shooting handheld at 400mm. I found that if I was seated in a chair and holding the camera braced reasonably well, I could often get sharper shots at 1/60 with the VR off than on. On the other hand, if I was standing up, and particularly if I was in an awkward position, the VR-assisted shots were invariably quite a bit sharper than my unassisted attempts. We've long heard from a variety of manufacturers that it's best to turn image stabilization off when working from a tripod, as the anti-shake system itself will add blur in trying to compensate for very tiny movements. This seems true of this lens, but I'd extend the caution to include situations in which you're braced well enough to provide a reasonably stable platform to begin with. Build Quality and Handling The Nikkor 80-400mm VR seems generally well-built and solid. Its zoom ring is a little stiff, but the flip side of that is that it's not at all prone to zoom creep. (Slipping out to longer focal length settings when the camera is hung from its strap with the lens pointing down.) As noted above, the manual/auto focus ring is quite stiff, and a little chunky-feeling as you move it in or out of its locked positions. The barrel finish is the matte black paint coating with a slight spackle pattern that's found on a lot of Nikon gear, including most of their camera bodies. The lens has a tripod mount attached to it via a rotating ring near the base of the lens. The ring can be rotated through 360 degrees, and can be locked in any position with a small knob. It can also be removed entirely in one position. I wasn't at all crazy about the feel of the tripod mount ring though: The bearing surface between the ring and the lens barrel is just covered with short-nap fiber flocking. It's more than a little stiff to rotate, and I wonder whether the flocking will hang tough over the long haul. Fortunately, there appear to be third-party aftermarket tripod-mount rings that avoid these problems. The tripod mount seems to be a bit forward of the neutral balance point: With a lightweight DSLR mounted on the lens, the combination is slightly back-heavy at 80mm, becoming evenly balanced only at 400mm. With a heavy body like the D2Xs, the combination will be back-heavy at all settings. Regardless though, the balance is far better than it would be if you used the camera's tripod socket, and the tripod mount does take a lot of load off the camera's lens mount. The Nikkor 80-400mm VR comes standard with a very rugged-appearing padded ballistic nylon carrying case and a strap for carrying it, and a (huge) HB-24 hood for preventing glare. Summary We were a little surprised that this lens wasn't sharper at 400mm than it was, but it does a great job of reaching way out there, amounting to a 160-600mm equivalent zoom on a DX-sensor DSLR. Combined with an effective VR system, this would make a great "walking around" lens for the nature photographer. (600mm equivalent, image-stabilized, in a lens this small? - Crazy! - And loads of fun!)

10 out of 10 pointsand recommended by COMPLEATANGLER (2 reviews) Vibration reduction works as advertised. Tack sharp. Opens up a new world of walk around telephoto opportunities. Not a lens for fast action in low light As I am not as young as I used to be and a larger percentage of my telephoto pictures were suffering from too much camera shake. This lens has solved that problem. This is a great walk around lens for wildlife, people, & landscape photos as you can easily get by without the need of a tripod or monopod. On my D70 this is a 160 to 600mm lens. I can shoot at 1/30 of a second and get consistently sharp results thereby negating the slow aperture of the lens. Sharpness & color are super. I am very pleased with this lens. My only regret is waiting so long to buy one. |
