Overall

The 24-70 2.8 is a BIG lens. It easily steals the title of "The Beast" away from the legendary 28-70 2.8. Fitted to a D40, D50 or D80 the lens feels absurdly large for a normal zoom and even on the grip-equipped D300 it's large enough to throw things off balance. The mechanical operation of the lens is virtually perfect and doesn't get in your way.

Optically this is close to perfection as I've seen in this range. Wide open it remains VERY sharp as seen here:



This is better than any prime in my kit, though perhaps my 50mm 1.4 can match it at 2.8 (though with less contrast/pop). It clobbers my well loved 24mm 2.8 for example by serving up tack sharp images with lots of pop. Stopped down even a bit the lens becomes even better of course. Bokeh is very good to excellent. It's not a match for the 85mm 1.4, but it's up there with the better lenses. Color is not something to be concerned with as this lens seems to have no visible effect on the spectrum. It's a virtual zooming window for the D300.



Flaws?

In my tests and usage of the lens there are no real-world flaws. While this lens exhibits some distortion, it's rare to be a problem unless you're shooting architecture. In fact I don't notice it 99% of the time since I'm shooting people with this lens. Beyond that you can easily correct the issue in post.

On the D300 there is absolutely NO CA at all and very little corner darkening wide open. This is my second 24-70. The first was also perfect, but I gave it to a friend who couldn't score one for hes China trip. So I'm happy to say that two samples several months apart were both excellent.

The Dreaded Range

There are plenty of posts asking about this lens vs. the 17-55DX, which suddenly seems like a bargain! It depends on your style and the venue. In a small room shooting a kids party you might find the 24mm too tight on a D300. Having used the lens indoors I don't feel that restriction, but some might. On the other hand the 70mm end makes this a far superior portrait machine to the 17-55DX. It's also optically better than the 17-55 over the overlapping range. Your style of composition will dictate how good a choice this lens is. Some folks walk around all day with a Sigma 10-20mm on their cameras, but I'll do the same thing with a 85mm 1.4, so it's a personal pick.

Other Ideas?

Well, believe it or not, I toyed with the idea of adding a Canon 40D and 17-55 to my kit. That combo is only a bit more expensive than the 24-70!!! My logic was that the 17-55 has VR (IS) type stabilizing and I'd have another camera body to play with. I passed on the idea in the end because I wanted the 55-70 range and the state of the art glass on the new Nikon. I knew that, after I bought the Canon, I'd still want the 24-70!

Finally

Good lord, what a GREAT lens! For 1800 buck it had better be as well. With a FX format machine on the horizon for many of us in the next couple of years, it's easy to get serious NAS for this hunk of glass. It's clearly a lens that can remain in your kit for many years to come and it's a natural partner for my 70-200. At the end of the day, should the 24-70 fit your style of shooting, the lens' single weakness might be size and weight for some. In actual use it doesn't feel much smaller than a hoodless 70-200 AF-S. Big lenses equal big performance at this price point I suppose.

Hope this has been useful for some!

Cheers,

Thanks for your review. I've been using my tamron 17-50 2.8 & Nikon 85 1.4 for portraits (usually upper body of children). With the tamron I'm often at 50mm. And the 85 1.4 is great for headshots but it's too long for much else (indoors).

I also have the Sigma 30 1.4 which I find a little too long. I was comparing the 24 2.8 with the 24-70 2.8 at photozone.de and I was surprised at how the 24-70 kicks the 24 2.8 and most other primes.

So I think this will be my next lens. My only hesitation is the cost and size. Size isn't a big deal since it'd be mainly at home indoors. Cost is an issue because this is just a hobby for me.
 
Good review; the only issue I'd qualify is the 'size' one - it balances really well on the D300 and a smaller lens doesn't feel right any more!!! I also have a sigma 150 which is very similar in size and 'feel' - these two lenses occupy my D300 for 99.99% of the time.
 
Excellent practical overview (and nice sample pics too ...).

I'm currently in purchase orbit around this lens for my D300 but the two things that are keeping me from pulling the trigger are it's size and the lack of VR.

You talked about the size issues but do you find that the lack of VR impacts your keeper rate ? I know this isn't such a major deal for this focal range + it can be addressed with proper technique and/or tripod but I'm talking about casual shooting ... Any issues there or is it all 100% sharpness and Bokeh ?

Thanks !
 
Nice review followed by an excellent shot to demonstrate its capabilities - too expensive for me to add to my shopping list, but good luck to those of you who buy such a lens - I shall try to hide my jealousy ;)

Wake me up before you go go!
 
Sure, the 24-70 2.8 AF-S with VR would be an even more capable lens, especially around 60-70mm. Then again, I already own the 70-200 which has VR at 70mm. Still, a lot of folks would have liked VR.
So here's the story:

The 24-70 is a HUGE lens. We can debate day and night about whether it's too big or too heavy on this camera or that, but no one will ever call it light and compact. It's larger than the Canon 17-55 IS for example and it's size is part of the compromise for it's optical superiority. Adding VR would make the lens larger still and probably bring it up to about 2100.00 US in cost. This lens is already a lot to swallow for some shooters on a budget. My wife does NOT like the size on her D80.

I agree with most that the wider range does not really need VR. Some still want it and you can't really make people "not" want a feature they like. But the fact is this: The glass and engineering in the 24-70 is absolutely the state of the art, besting every other Nikon or Canon lens I've used over the same range. Subtracting the mechanical VR feature does not alter that fact. Buying a 40D with 17-55 IS would have, on some occasions, given me an advantage. But I wanted a lens that would give me the best IQ in the majority of situations, while also going beyond 55mm. For example, I preferred the 35-70 2.8 to the 17-55DX mainly because of the range.

In the end it comes down to styles again. Would I have a better keeper rate with VR? Maybe at the long end in more challenging light. VR works, though keep in mind that a D300 has clean high ISO's and the 24-70 is VERY sharp wide open. That's all many will need for faster shutter speeds. Those with shaky hands can buy a 16-85 VR or look hard at the Canon/17-55 combo. There are plenty of options around.

The 24-70 is the best normal zoom I've used. Most reviews seem to love it, but I actually think it's better than the reviews have indicated.

Excellent ... thanks !

Again appreciate the review and the VR follow-up.

I guess I've turned into a bit of a VR junkie given I have the 18-200, 105 2.8, and 70-200 2.8. I've lived without it until recently but now I'm addicted. This seems like the perfect lens to break the habit :)

Cheers

I actually turn VR OFF when I feel it's not needed. I think it can effect sharpness negatively at times. You'll enjoy the 24-70. It's a beautiful lens.

Thank you for your review. It seems you like the lens a lot and I agree it feels great.

I have a few questions.

I see a lot of field curvature, especially at 24mm. What is your experience? If you feel there is not an issue related to field curvature on your lens, please can you post an image at 24mm and focused on a distant (infinity) object? Up until this moment, I haven’t seen a sample with edge-to-edge sharpness, although a lot of people claim they don’t see it.

I notice some CA on my lens, although it’s less compared to my previous sample. Did you take a picture of a high-contrast scene, like a tree branch against the sky? If so, please could you post this picture as well?

Thank you.
 
Thanks for the great review. Im just wondering if you could photo this mounted on a D80 (or D70)... im trying to hunt down a copy, but, they're all back order at every place ive been to (in in Canada). Thanks.
 
I am one of those folks on the waiting list. Got the lens right after it came out.
It has horrible corns and was returned soon after.
I really want to give it a try if QC isn't as bad as the 1st batch.

Does anyone still see bad corners?

Thanks for the write-up. You've hit the nail on the head in terms of why I chose the range of this lens over the 17-55 - oh so much nicer for portraits. Like you, I like to shoot people, and 55-70 does more for me than 17-24. Can't wait to get this thing. Ordered it from Allen's Camera and it's due to arrive Monday! Should complement my 70-200 VR nicely. :-)
 
True on the size front the 28-70 was a heavy monster too when i owned it a few years ago but the reason why Canon Efs 17-55 is lighter is that it is a crop lens optimised for 1.6x crop glass and the glass will cover less surface area than the FF Canon and Nikon 24-70 f2.8 which are similar weights with out IS/VR.

Thank you for your review. It seems you like the lens a lot and I
agree it feels great.

I have a few questions.

I see a lot of field curvature, especially at 24mm. What is your
experience? If you feel there is not an issue related to field
curvature on your lens, please can you post an image at 24mm and
focused on a distant (infinity) object? Up until this moment, I
haven’t seen a sample with edge-to-edge sharpness, although a lot of
people claim they don’t see it.

I notice some CA on my lens, although it’s less compared to my
previous sample. Did you take a picture of a high-contrast scene,
like a tree branch against the sky? If so, please could you post this
picture as well?
The field curvature has been mentioned elsewhere and it is the nature of this lens design. At the widest end, shooting architecture, it is visible. But why would I employ this lens for that? Surely the 12-24, 14-24 or even the new Tokina 11-16 are better picks for such work on DX.

As for CA I see none on the D300. None at all. Putting the lens on the D40 I still see none, but I haven't looked for it either. Clearly, if there is any with the D40, I've yet to spot it, which is a good thing. If you're seeing CA, you don't have a good sample. My friends who own this lens also report no CA.

Edge to edge sharpness is NOT something to expect from this lens at the wide end. It's design goals are elsewhere, such as people/portrait work. For that type of shooting it has no equal in it's range. No single lens can do it all. Even the near-perfect 70-200 has a weakness or two.

I will say this though. Based on my experiences with the D200 (I owned two), I would not expect the greatest results from the 24-70 on that body. In fact, my 85mm 1.4, 50mm 1.4 and 35-70 2.8 never gave me their best until I bought a D300.

Ok, thanks, I already accepted field curvature as a normal abberation on this lens. but since you didn't mentioned it, I thought maybe you did not experience it.

The CA is a difficult one. My first sample got it about 6 pixels wide and my second and much better sample only 3 pixels wide on some very high contrast scenes. Maybe this is normal, I don't know.

I will build experience with this lens and maybe I can calibrate it to something better in the future.

For criticul work, I think I will keep using primes, but for ease of use this lens is great with excellent results in the centre. I must confess for $2400 it dissapoints a bit, but maybe I was too criticul and used primes too often (this is my first zoom).
 
Hendrik - absolutely no CA with a 24-70 on a D300 or D70 here. I had a look at your new lens images - the longer look fine but the 24mm os very soft on the right side of the image fully open - as the left side doesn't seem to be suffering in the same way, there seems to be something amiss with the lens - as the houses are not the same distance away, f2.8 DOF may be the issue but it looks more to be a problem with the lens

Primes I use are 24mm 2.8, 35mm f2, 50mm 1.4, 85mm 1.4. With the exception of the 85mm 1.4 amazing bokeh, the 24-70 is better in every regard compared to the primes. Sharpness, color, contrast are all better. Wide open there is zero CA no matter what the scene. I looked at your review and samples. I think your second copy is soft on one side as well. If it's showing CA at all I'd return it.
Sample variation happens, even with high end glass.
