I don't see what difference it makes. You could use lenses that go to f1.4, so why wouldn't you? What advantage is there to using one that goes only to f2.8?

I don't really know where you're coming from to be honest, you're trying to compare a 1.4 fixed length lens with a 2.8 zoom lens![]()
Sorry Dan, but that is one condescending post :|.
I don't come from a 35mm film background, so I don't really 'feel' the improvements in high ISO shooting that come modern DSLRs and I shoot a D700! But, there are plenty of times when I find that I can't get the shutter speed/ISO quality relationship that I want (as I don't do all of my photography in bright sunlight).
Halving the shutter speed (f/2.8 vs. f/4) is absolutely crucial when you find yourself on the limit of what your camera/lens can offer you :shrug: and that happens to me quite often enough (especially with the longer lenses for wildlife shots, where camera shake and/or subject motion blur come into play) to justify my preference for 'faster' glass.
And what about bokeh :shrug:!? I'm a shallow DOF junkie and even f/2.8 doesn't do enough to isolate the subject for my tastes, when that subject is not close to the lens. F/4 is only any good at blurring backgrounds if you have a close subject and a distant background - high ISO isn't going to help you there either.
To state, as you did, that "an extra aperture is no reason to 'cling onto' a lens", suggests to me that you are not in touch with what many people want from a lens.
Sorry, but I just had to put my opinion on record :|.
Cost maybe (and not to mention lens size)...? Not everyone can afford f2.8 lenses, and so an f4 range is the next best option. People have complained for years Nikon don't offer a god range of f4 lenses like Canon so it's good they are now catching up. A 24-120 f2.8 would be massive and mega expensive. For those that want the extended range it offers over the 24-70, if the f4 is optically good then it makes sense.
We will have to see what the real selling price is after launch, but at this stage we are talking just over £100 difference on +£1000 lenses - if you cant afford the 2.8 you probably cant afford the f4 either. Hardly think this is an affordable lens... if it was around £500 I may be tempted to go for that... but not at that price when i could get the best mid range zoom around for not a lot more.
At nearly twice the price of the un-fautable existing model....hhhmmm :shrug:
Though I will try it just to see if they can improve on perfection![]()
That cost comment was more aimed at saying having the 24-120 and f2.8 would be more expensive. I get why it's an f4 lens and I get why some might choose it over the 24-70, because of it's extra reachWe will have to see what the real selling price is after launch, but at this stage we are talking just over £100 difference on +£1000 lenses - if you cant afford the 2.8 you probably cant afford the f4 either. Hardly think this is an affordable lens... if it was around £500 I may be tempted to go for that... but not at that price when i could get the best mid range zoom around for not a lot more.
Coming from Canon brace yourself for about 1,000 'Should I buy the 24-70 or 24-120?' threads. On the 85mm f/1.4 is there any reason Nikon has never released an 85mm f/1.2 like Canon did? It's one of the lenses I miss moving over to the D700.
Just a note on the 'its the same price as the 24-70' comments - what's the actual srp for the 24-70?...about £1500 I think, so actually the new 24-120 will probably settle and end up a fair whack cheaper.
The 24-105 or 24-120 DOES have its place, but its usefulness is less of that of the 24-70.
That's surely just an opinion...the extra reach and VR may well be a lot more useful to some, assuming the optics are decent.
No condescension - a shame you read it that way, but it's probably because it doesn't read with the same intonation that I envisaged when I wrote it. No offence meant, so don't take any, and accept my apologies if you have already.
Still, I'll restate my standpoint here - I love faster glass and that extra stop - but I appreciate that "on the limit" photography is way beyond the limits imposed on us even as recently as 5 years ago. I guess it can be summarised thus; "we all want one extra stop"...! Is it that we won't be satisfied until we can handhold 600mm primes in full-darkness? If you can't handhold a long prime at night for fast action, that's because you're pushing the boundaries of light, physics and available electronics, and there'll always be a situation in your work where the movement is too fast and the light too low; it's just the goalposts move with every improvement in sensor technology. But for the great majority of photographers f/4 coupled with the increases in clean ISO made over the last few years is plenty good enough to justify carrying an f/4 rather than an f/2.8.
You mentioned nicer bokeh - that's to me another example of what I'm talking about when I mention reasons to go with faster glass.
, which is why I brought it up./me waits for some Nikon shooter to show me Nikon DID make a 1.2, in MF.

They can make f/1.2 lenses! :nono: :rules: (and still do :razz
Daniel
I stand corrected.
But is it AF ?
Lets assume the optics are decent, on par with the 24-70 even.
VR is useful but there are always the Monopod or rest the camera somewhere....sure, its cumbersome to carry a tripod, i give you that. But people who shoot landscapes do carry a tripod around so it makes the VR pointless. The only example i get when VR is useful is when shooting inside a building, like a church, where a tripod is prohibited. Well, unless you shoot inside buildings a lot then this is going to be pointless. As also, VR can't stop motion.
Extra reach - I always thought about that, but i have learn early on that it is MUCH MUCH MUCH more easier to walk forward than to step back. Not applicable here but my point is that stepping forward to make that 50mm is not difficult. I do concede that it is useful, and I have already said the 24-105 and the 24-120VR has its place in both line ups. I am just saying the 24-70 can take photos in more situations that 24-120 can but not the other way round.
Wow, what is this hang up on 2.8? Such a lack of consideration for an alternative with more range at f/4 in here. About 2 of us on this forum need 2.8. haha
There is no alternative to the 24-70. And don't fool yourselves, the only reason folks lug around heavy equipment with no range is IQ then 2.8 not the other way around.
What, a 24-120 2.8? Whatever. Like I want to carry that and a 70-200 around.
The 14-24 may be the sharpest lens in Nikon but it is given up because it won't take filters and the range is short for some. It's got nothing to do with losing f/2.8.
The 16-35 is selling well and is popular on the Nikon forums because it is sharp and it takes filters. Filters and range over 2.8, imagine that? This 16-35 is still near £900.
On DX, the 16-85 has a more usable range than the 17-55 2.8. The difference with this pair is the 16-85 is much more affordable. Who wants heavy limited range though!? I admit I loved my 17-55 but only kept the 16-85 as a walk around lens.
FX bodies are already big. We need some smaller lenses with good IQ with less weight and size. Look for more f/4 lenses from Nikon in the future. With bodies like the D3s, F/4 is really the new 2.8 from a light perspective. (Yes, f/4 does produce some bokeh.....really).
Of course, all of this rests on IQ right now. I suspect the 24-120 will drop in price nearer to the 16-35 after it hits the shelves for a few months.
I'll say it again, if the 24-120 is good in the IQ area, I along with many others will sell our 24-70's to fund this lens instead for the reach alone. If I can afford it, I'll keep the 24-70.
If the IQ is absolutely as good as the 24-70f2.8 then for a lot of purposes it would be useful. In the studio it would be a bonus. It would just be another option really but as a lot of people carry both the 24-70 and 70-200 having the 24-120 just gives an overlap unless the 70-200 is fitted to a crop body in which case this would be a useful combination.
Agreed. Where is the 120-300 f/4? ;-)
Thanks Arkady
Even though the 55-300 has a slightly longer range than the current 70-300, its cheaper ?
They do; the new one just has fairy dust coatings and an internal focus motor (Silent Wave Motor.) And a CA $1900 price tag compared to $1200 for the AF-D.
The phrase 'walkabout' makes me want to kill myself.

All this argument about f/2.8 vs f/4 is surely the reason why Nikon have introduced the new lens, with a different but equally valid set of compromises.
Thos are very impressive graphs Dan. 24-120 should be very good![]()
These graphs are the Canon 24-105L 4 and should be directly comparable http://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup/ef_24_105mm_f_4l_is_usm For those unfamilar with these things, and a couple of graphs don't tell the whole story but are a good indicator, I would say that the new Nikon lens will be at least as sharp as the Canon and well able to hold its own against the 24-70 2.8.
...
I don't know, I guess it's me but I think the sharpness of the 70-200 is awesome, but the 24-70 isn't any better than the 24-70 Sigma HSM I owned and swapped previously.
I'd be seriously interested if build and optical quality is up to scratch!
I think if you really had a Sigma that was as good as the 24-70 you either had the world's worse Nikkor, or a handcrafted by fairies Siggy 24-70 HSM
I'm no lens snob, but the Nikon 24-70 really a LOT better than that Sigma.
I don't get why you need VR for weddings - this is a short lens and should be easy to handhold, and VR doesn't stop motion blur.
I would say you need f/2.8 more than you need VR.. dunno I don't shoot weddings, but I can't see how a slower lens with VR is ever going to do better than an f/2.8 lens in a low light scenario?
I don't know how to read these graphs, Richard, but do they tell us anything about image distortion at all :shrug:? I would have thought that this would be the obvious drawback with such a wide range of focal lengths, but I'm no expert :|.
All other things aside, f/2.8 lenses are much bigger and usually around twice the weight of f/4 equivalents. That's an issue for most people on general walkabout.
agreed i would be tempted by the weight saving and carry 50mm for the dark bits
Weight: Approximately 710 g
