Nikon 70-200 VRII vs Canon 70-200 Zoom Test! Interesting results!

You've probably described the reason why Nikon made the 70-200/2.8 II lose focal length - to avoid an area of decreased performance at close distances. This problem exists at least on two previous f/2.8 telezooms that I've used - they both were poor at f/2.8 near minimum focus at the long end of the zoom range.
 
In threads about your 200mm f4 close focus problems, you seem to say that you found the cause, and it is the IS that seems to be problematic, not the optics.

You then go on to show it without IS performing like this:



http://forums.dpreview.com/forums/read.asp?forum=1029&message=23963542

So... that makes the story quite different... you apparently have (had?) a problem with that lens with image stabilization at close focussing, and it is not about soft images at close focussing.
 
This is image is still not sharp.

I just said that when IS is off it may be better but it is not good

Here are my old tests

http://mfurman.smugmug.com/Photography/Canon-EF-70-200-f40-L-IS-tests/2842902_M92Lx#152315863_xDrU8

You can see original size.

This is a typical behaviour for this lens. It is very sharp at 200 mm and focusing distance > 9 feet

You can also see some other tests here but I will need to give more explanation:

And yo know this because?????
the odd few people who complain on this forum are not representative of all the professionals who are out shooting with this superb new lens and making more money a month that most people do in a year. Nikon will sell thousands of copies of this lens, how many people are actually complaining.
 
So what is the problem? What happened there? How come Nikon’s lens the way it is? It seems to me that Nikon engineers where designing this lens on DX test rig.
BS. This is the effect of the internal focus optical design. I'm not saying the effect is not there. It obviously is. But it's got NOTHING to do with DX, and neither is the lens wrongly labeled as a 200 mm.
BS too. No other 80-200 or 70-200 shows the same effect, yet all are of "internal focus optical design". I am not saying there are no IF lens designs which do NOT show this.
It is a consequence of internal focus. If you have a better explanation, I'm all ears.
It is NOT. Read what I wrote:

And there are MANY IF lenses that do NOT show it (all other 70-200 and 80-200 lenses).
But there are MANY non-IF lenses that show it (think all 18-2XX/28-200/28-300 ultra zoom lenses).
The 18-200 DX VR, which is a very prominent example of this issue, is an IF design. Don't know about the others.
And there are MANY IF lenses that do NOT show it (all other 70-200 and 80-200 lenses).
Not at all, or not to this extent? Well, the debate is on, obviously (given some other posts above), and your statements go contrary to everything I've read about optics so far. But I'm not an expert, so, if you have some reasonable other explanation, put it forward...
Not at all. They go LONGER at near focus.

Longer, not shorter. And they are IF. Like the Nikon 80-200 f2.8 D apparently, and the Canon 70-200 series. And just about every other 70-200.
 
bacause Nikon will sell 100's of thousands of this lens, how many actually are complaining? if you think the influential people that Nikon listen to are on this forum you are dilluded in fact i don't know why i'm bothering to keep replying to ILY.

You are the only one claiming this - yet I have not seen any proof of this to be true.

As I understand IF design, it is simply not possible to get a longer focal length with shorter focus distance.

Here is a challenge - show us the proof in the form of test images where the 80-200 AF-S gives a larger reproduction than a lens that is known to be close to 200mm at min focus distance!

Until then, I call all your loud shouting just BS.

Maybe some other experts on this topic would weigh in? Thom? Iliah? Anyone...?

Take my WORD for it. Or simply go try out such a lens in any camera store near you. Stop being pedantic, I am merely stating FACTS.

If you understand IF design, I am SURE you can EXPLAIN why you think that.

So, lets hear why you are of that impression, as you say you understand IF design.
Here is a challenge - show us the proof in the form of test images where the 80-200 AF-S gives a larger reproduction than a lens that is known to be close to 200mm at min focus distance!
Give me a server to upload to, I have typed to you the same message for 3 days now: I DO NOT HAVE A SERVER TO UPLOAD ANY IMAGE TO RIGHT NOW.

And I also have told you many times already, I am using the INTERNAL FOCUSING Canon 70-200 f4 L. It was a Nikkor 80-200 f2.8 D user who saw exactly the same with his lens.

It is nice, that you want to call that user from that other thread a liar, and want to call me a liar, but you have NO foundation at all.

You do not know a thing about lens design, and you keep on using nonsensical simplistic formulas too, even when you are pointed out that the formulas are nonsense.
Until then, I call all your loud shouting just BS.
No, you call me, and others, who state facts, liars.
Maybe some other experts on this topic would weigh in? Thom? Iliah? Anyone...?
Again, go out and verify it yourself. And read some books about optics and math.

Or, give me a server to upload an image to. Or all the above.

We do need to send a loud message on this. Part of me wants to keep this thing, because it is very nice, but it also sucks.
So far, the only reason I've seen you say it sucks is because the numbers aren't the same.
Essentially, in the "wedding photographer distance range" of 5 to 20 feet,
Show me a 70-200mm I image taken at a wedding and at 5 feet and 200mm. Also show me images from both at 20 feet and 200mm. I'm hearing rhetoric from you, but I'm not seeing actual evidence of the problem. And don't show me tests. I mean real images you took at weddings that used 200mm with the first version at very close distances, and real versions of 200mm in use at longer distances (which I suspect is where you actually use it).
Thom -

By your own self description, you are notorious for posting only "test photos" and withholding your real work for real purposes. I know you have your reasons for that, as I've read your statement on it. Therefore I find it wildly ironic that you of all people want to start a pi$$ing match over "actual photos." As a matter of practice, I do not put wedding faces on this forum. However, I just did a search of my hard drives on "200mm" and grabbed a few of the first examples that came up. They are not necessarily my best shots nor the best examples, but each of them illustrates a full frame crop from a true 200mm view (190 or better anyway) taken in the trouble zone of 4 to 15 feet. You seem to be rather emotional about denying my actual experience with this lens that you don't even have yet. As to "real world" shots, the one I did with the Rolleiflash and mixer and box is a perfect simulation of a shot that I shoot at pretty much every event, which is what you might call "staggered and compressed heads," which also works for details. If you deny the value of that "test shot," you are being rather irrational and rhetorical just for effect. But like I said, I don't put wedding faces here, so like yourself I show a test shot rather than the real think in that particular instance. Now on to some "actual photos" which the VR2 would produce in poorer form, either due to lack of foreground-background compression, wider AoV in background, less background blur, or less magnification...

First, this bird flew right at my face and was taken in the problem range. If taken with VR2, there would be less BG blur, more AoV in background (busier), and less magnification. Probably still a good image, but not nearly as good (not that I'm a wildlife photog; I'm clearly not!):



This picture of Robert Plant would be at a steeper angle and/or lower magnification and have a less blurred background if shot with VR2. Since you asked about weddings, I can tell you that plenty of shots are taken at this exact range at weddings.



This is a classic table top "wedding detail" shot of 2 flowers, one highly blurred out in background. The VR2 cannot do this nearly the same way, only to a far lesser degree (until of course you add the TC).



This simple ceremony detail would not work as well with VR2 either:



The next three shots are wedding details at or within a couple cm of MFD that the VR2 could not capture nearly the same way (in absence of TC).







This shot of Fogerty would suffer as well, because it is well within the problematic range. Shots of this framing are typically shot at weddings as people come down the aisle, since you want to know about weddings.



This is a VERY important shot where the VR2 will suffer. This does not look like much, but at 200mm and within the problem range for VR2, this shot from VR1 has enough magnification to easily show the rings on their hands when you zoom in. At this range, the VR2 would look like a 140-150 and have far less magnification of a crucial detail, not to mention the other usual qualitative differences pointed out above.

Can't tell. Just another person who claims something without proving the statement.

Look - we know for a fact that most IF lens designs - e.g., Nikon 18-200 VR, Sigma 120-300, Nikon 70-200 VR II - lose focal length as they focus closer. This is because the rear element is moving which shortens the focal length.

The 70-200 VR I also shows this effect, albeit minimally. The 80-200 AF-S does, too - as far as I know. Now you come along and claim that that is not so - ok then, show us...

Mike
 
According to Nikon's specs, the Nikon 70-200 f2.8 VR (I) and 80-200 f2.8 D do NOT show this effect.
But you, who loves to use a nonsensical formula, keep on claiming it does.

Can you point me to those specs? Where exactly does Nikon state that the 70-200 VR I or the 80-200 AF-S remains a 200mm lens at min focus distance?

All I can see from their specs are min focus distance and magnification at min focus distance. Those specs lead me to believe that these lenses are in fact less than 200mm at about 1.5m distance.

I think most folks here would agree with me on this issue - so show us that it is not so and we are all wrong!

Why do they lead you to believe that?
Only because you keep filling them in in that WRONG formula?

Try this:
http://www.giangrandi.ch/optics/lenses/focalcalc.html

(and/or this: http://www.bobatkins.com/photography/technical/measuring_focal_length.html )

Nikkor AF-S 70-200mm f2.8 G VR ED:

(keep in mind that they are just manufacturer specs, they may be a bit different from reality)
From Nikon USA dot com:
Max magnification: 1:6.1
Min focus distance: 1.5m

Lets take a subject of 500mm as example, as that is the default value in that calculator. It does not matter, as we are not actually measuring, we are just using manufacturer data.
Object size: 500mm
Image size: 1/6.1 = 0.1639 * 500 = 81.97mm
Object distance: 1.5m
Calculator gives: focal length 211mm

So, that is using the manufacturer's data. It of course is more interesting to actually use real measurements.

Nikkor AF-S 80-200mm f2.8 ED:
Object size: 500mm
Image size: 1/6.3 = 0.1587 * 500 = 79.36
Object distance: 1.5m
Calculator gives: focal length 205mm

Again, this is using manufacturer data.

Nikkor AF-S 70-200mm f2.8 G ED VR II:
Object size: 500mm
Image size: 0.12 * 500 = 60
Object distance: 1.4m
Calculator gives: focal length 150mm

Again, just using manufacturer "specs" regarding minimum focus distance and maximum magnification ratio. Using real measurements will give more "life like" results.
I think most folks here would agree with me on this issue - so show us that it is not so and we are all wrong!
See above. And, feel free to try the 80-200 or a Canon 70-200 f4 or f2.8 yourself in any store near you. Or a Sony 70-200, or a Sigma or Tamron 70-200. It is not like it is hard to discover things for yourself.
Almost as easy in fact as calling people who have seen it from experience liars.

Thom -

I have to reply to myself about my examples above. I have done a little measurement reconstruction, and it turns out that my Fogerty shot, the ceremony detail shot (flowers and back of bride) and rings shot were all probably taken right between 18 and 20 feet, where it starts to be way less of an issue. So, yes, there would be some suffering there, but not as much. So having chosen less ideal examples at first, I just found a completely ideal example of a ceremony detail in this one:

This photo was taken at 200mm with VR1, and I have reconstructed the distance with VR1 to be 157 inches. Marianne's "2.5 foot" rule applied perfectly here, and I got the same composition in my reconstruction at 127 inches with the new lens--which achieves same foreground framing but not image equivalency in terms of other desirable aspects. Unfortunately, this crucial example puts the VR2 in the sub-12-foot range where I know I don't like it. My Rolleiflash test photo (I know you're pretending not to like test photos today, but it makes the point beyond doubt) shows that the VR2 really disappoints with regard to background characteristics at this range, so this is a key wedding example for me.

All you have to do is try it yourself. I'm sure you have at least one IF lens? Both my zooms and my one IF prime narrow their AOV as the focus distance shortens
