Teljes méretű vetített képAz APS-C méretű képet vetítő objektíveket kimondottan a digitális fényképezőgépekhez fejlesztették, ezért nem használhatók filmes gépeken, vagy olyan digitális fényképezőgépeken, amelyekben az APS-C méretűnél nagyobb érzékelő található. Ultrahangos AFAz ultrahangos automatikus élességállítással szerelt objektívek általában halkabbak és gyorsabbak, mint a tradicionálisan működő objektívek. Egy vagy több alacsony szórású lencsetag is van benneAz alacsony szórású lencsetagok segítenek csökkenteni a kromatikus aberrációt. Nem stabilizáltA képstabilizátor segít csökkenteni a kéz remegéséből adódó elmosódásokat. A stabilizátor hatása elsősorban nagy gyújtótávolságnál és gyenge megvilágításnál érezhető. A képstabilizátor 1-3 fényértéknyi előnyt biztosít a nem stabilizált objektívekhez képest. Fém bajonettAz olcsóbb objektívek általában műanyag, míg a drágábbak fém bajonettel készülnek. Általában a fém bajonettek tartósabbak, így gyakori objektívcserénék ez a szerencsésebb. Ha egy fényképezőgépet főleg egy objektívvel használunk, akkor a bajonett anyaga nem annyira lényeges. Belső élességállításúA belső élességállítású objektívek mérete az élességállítás során nem változik. Nem belső zoomosA belső zoomos objektívek mérete a gyújtótávolság állításakor (zoomoláskor) nem változik. A front lencse fixA fix frontlencse az élesség és/vagy a gyújtótávolság állításakor nem fordul el. Ez lehetővé teszi, hogy a fotós szirom alakú napellenzőt használjon. A fix frontlencse megjönnyíti a polarizációs szűrők használatát is. Nem időjárásállóAz időjárásálló objektívek védettek a víz és a por ellen. Ugyan nem vízállóak, de esőben és más nedves, párás környezetben is jól használhatók. Egyes szigetelések csak a víz vagy csak a por ellen védenek, nem mindkettő ellen. A szigetelés csak akkor működik, ha az objektív egy hasonló módon szigetelt vázon van. Nincs becsúsztatható szűrőA becsúsztatható szűrőket olyan objektíveknél alkalmazzák, amelyek frontlencséje túl nagy, illetve amelyek látószöge túl nagy ahhoz, hogy hagyományos szűrőket lehessen rájuk tenni. Általában a nagy fényerejű tele, illetve az ultra-nagy látószögű objektíveknél fordul elő ez a megoldás. |

A vadonatúj AF-S 24–70 mm f/2.8G ED általános zoom objektív a NIKKOR professzionális objektívcsalád új tagja. Az elődjénél (az AF-S Zoom-Nikkor 28–70 mm f/2.8 objektívnél) sokkal karcsúbb új modell kiemelkedő jellemzőkkel rendelkezik nagy látószögnél, ahol a kép közepén és szélén egyaránt rendkívül fontos a megfelelő felbontás; ennél fogva az új objektív kitűnően alkalmazható tájképek fotózására. Az 50–70 mm-es zoomtartományban a részletgazdagság remek háttérelmosódással (bokeh) párosul, így az objektív portrék készítésére is kiváló.

I know what you're thinking: Seventeen hundred bucks or more for a mere midrange zoom?
There is nothing "mere" about this zoom!
Wide open, Nikon's new workhorse is sharper than most prime lenses. That's right -- I shoot all day long at f/2.8 (I like resulting blurry backgrounds) and never, never lack for sharpness. Being able to shoot f/2.8 at night doesn't stink, either.
Colors are vibrant, the bokeh (out of focus areas) is creamy, and you'll see ghosts and flares *only* when shooting straight into the sun. And I've never seen an autofocus do its thing so quickly or with such accuracy. I'm catching a lot of shots I used to miss.
No lens is perfect. This one has exactly three drawbacks.
1. It's pretty darn big for a midrange, so sometimes I miss Nikon's compact 18-200mm zoom. And that's without the massive lens hood in place. Snapped on, a big lens gets even bigger.
2. The zoom ring is too close to the camera body. I've only been shooting with it for a few days, but I keep grabbing the manual focus ring by mistake. There's a learning curve here, and I'm not yet over it.
3. It's in short supply. Good luck finding this beast at the suggested retail price.
On my D300 however, it's as perfect as a giant, expensive hunk of glass can get. It takes all my standard 77mm filters, and its DX-effective 35-105mm (approximate) zoom range makes it a great "walk around" lens. It goes wide enough for most landscape shots, and zeroes right in on my two-year-old's face.
But mostly I can't get over the sharpness, the color, and the responsiveness of the autofocus. I probably paid too much for mine, but it was worth every penny.

This is a magnificent piece of kit. The Nikon 24-70 F/2.8 is a professional -grade lens and shows this in every way. The build quality of this lens leaves nothing wanting--all metal construction, wonderful damping of the zoom ring--this is a beautiful instrument.
This is a full-frame lens, which means that it is suitable for FX Nikon cameras such as the new D3. However, this lens also performs wonderfully on the usual DX sensor for the other Nikon cameras such as the D200/300, D70s, D80, etc. When used on a DX camera, like all lenses, the focal length is increased by 50%. This is both good and bad. The "wide angle" end of the lens becomes 36mm rather than 24; on the other hand the 70mm zoom becomes 105mm--a very useful focal length. Overall, I love the range of this lens on a DX camera.
The image quality of this lens leaves nothing discernible to ask for. This is a razor-sharp lens at all apertures including wide open at F/2.8. Images on my D80 are colorful, contrasty, and did I say razor-sharp at all apertures? This lens is as good within its entire focal range as any prime lens I have seen, used, or heard of. Of course, the price of this lens reflects this, alas.
This is an AF-S lens, meaning that it contains an integral focusing motor (supersonic wave motor, or "SWM"). This, combined with the fact that this is an F/2.8 lens, causes it to focus lightening-fast. So this lens is great for action shots or low-light shots. Since this is an AF-S lens, it will autofocus on the D40/D60 series of Nikon bodies.
Some Nikon afficianados have complained that this lens does not have VR (Vibration Reduction) but VR is probably less important for a 24-70 focal range than for a longer zoom, and since this is an F/2.8 lens, it is usually feasible to increase the shutter speed of the shot to "freeze" the action.
A few points. The outer element of this lens extrudes, but not past the petal-configured supplied lens hood, which does a perfect job of protecting the front of the lens. Neat. One thing I am not crazy about is the relative placement of the manual focus ring and zoom ring. I sometimes confuse the two, and I think that given the fact that most people will use this lens in auto-focus mode rather than manual mode, Nikon might have placed the manual focus ring in a more out-of-the-way place. Not a big quibble.
This one is destined to be another Nikon legend!

The image quality from this lens is, as other reviews indicate, nothing short of spectacular. Having used its ancestor, the Nikon 28-70mm f/2.8, I am not surprised in the least. Despite specifications to the contrary, the 24-70mm feels lighter in my hands than the 28-70mm did, and if it is possible, somewhat more responsive. Perhaps the weight distribution is more even in the 24-70mm than it was in the previous iteration.
After using this lens for a few weeks, two things did surprise me:
1. I don't miss VR in the slightest. I was, to put it mildly, dismayed to find out that Nikon did not include VR in their latest evolution of their fixed-aperture standard zoom. I was, to put it mildly, pleased to see that I get proper exposures with 1/100s shutter speed or higher in all the situations where it matters to me. The configurable auto-ISO on the D300 is a life-saver in this respect; I expect this observation will only become more true as camera technology improves. I suspect Nikon planned this all along.
2. The difference between f/2.8 and f/4.5 is substantial. For the longest time, I kept using my trusty 18-70mm f/3.5-4.5 lens, because I felt sure that I wouldn't benefit very much from the extra 1/3 to 4/3 stops that the fixed f/2.8 lens has to offer. I was wrong.
I primarily use this lens indoors, and for basic portrait work. For these settings, it is exemplary; my only regret is that this lens may put my 50mm f/1.4 out of business. That would be a sad development.
Another area where this lens shines is quasi-macro work. With a reproduction ratio slightly better than 1:4, you get respectably close to small subjects, and have beautifully out-of-focus backgrounds at f/2.8 and 70mm. Shots of single flowers at close range against an interesting background, for example, turn out quite nicely.
I'm very much looking forward to using this lens for the next decade or two (or more). DX digital, FX digital, film-- whatever your game is, if you need a lens that covers this range, I don't think you will find any better than this for quite some time.

This is obviously one of Nikons best lenses ever. However, the one I received had several metal flakes, shavings, flecks, specks, whatever you want to call them inside the lens behind the aperture diaphragm on one of the inner elements. I of course had to send the lens back because this may have gotten into the diaphragm and caused problems. In all my professional career I have never seen this happen with a Nikkor pro lens. I did have it happen once with one of my old 28-105 Nikkors from the film days, but never with one of the gold rimmed lenses (pro).
Keep an eye out for it in case it's a common problem.
That's the only reason for my low rating, to let people know about this one issue with my lens.
Now I have to wait till someone has them in stock again. Maybe I should have just sent it in for warranty repair, I would have it back from Nikon by now because I'm an NPS member.
Great lens but I got a sour one!

Performance wise, it's a 5 star. For the price, you get some nearly the performance for fraction of the price. As an example, the 35-70mm f/2.8 D.
Let's face it, if you got the money and or need something like this as a pro, this is it. For amateurs, it's hard to justify blowing $1700 for this puppy.
It's big, almost as big as the 80-200mm f/2.8 D telephoto zoom. It's built solid and focus fast, faster than the 80-200mm. It does wide angle at 24mm, which is terrific, and is the best Nikon got for wide to standard zoom. It doesn't have VR, so the breathing and weight lifting exercises come in handy. It also is as heavy as it looks; 2 more pounds to the body for a grand total of nearly 4 lbs before any other attachments. Nano-crystal coating? Sounds good to me.
If I were shooting portraits, the 35-70mm is lighter and focus fast enough for me and balances better. This thing belongs on a D3 or a D300 with a battery grip for proportion and balance.
Would I recommend it? Not for everyone given the price to performance. Is it a rock solid high performance lens? You bet.
