AF-S DX Zoom Nikkor 17-55 mm f:2.8G IF-ED

I would not go for DSLR with APS-C sized sensor (DX format) if there is no such lens ever exist!


Background

Once upon a time, I was a die-hard for full frame (24 x 36 mm) DSLR. It is mainly due to the  focal lengths (or more accurately the angle of view) that offered with my lenses that I used to. With the film SLR, there are mainly 3 lenses serve me: 18-35 mm (wide angle zoom), 28-70 mm (standard zoom) and the 70-200 mm (tele-photo zoom). Among these lenses, almost 65% of my photos were captured within the range of 28-70 mm, while 25% of photos were within 70-200 mm and only 10% of photos were with 18-35 mm. So you can see how often the standard zoom lens I used and how important it is to me.

If I switched to DX format DSLR before the introduction of the AF-S DX Zoom Nikkor 17-55 mm f:2.8G IF-ED, there were 2 major problems came out to me: 1. the lost of wide angle shooting capability (so as to many photographers), and: 2. no suitable standard zoom replacement available to me. The problem 1 didn't truly affect me because I only shoot only a few photos among this range. But the problem 2 is really a big problem to me. As I mentioned, the view angle of 135-format equivalent 28-70 mm is so important to me. Nonetheless, I use both ends very often too!

If I use 17/18/19/20-35/40 mm as the replacement, what about the range of 50-70mm (135 equiv.)?
If I use 24-70/80/85 mm as the replacement, what about the range of 28-36mm (135 equiv.)?

No appropriate resolution, until...

Yes! Nikon gives me the best solution eventually: the introduction of the AF-S DX Zoom Nikkor 17-55 mm f:2.8G IF-ED. It is the only true standard zoom for the DX format DSLR in that time and it is the lens that made me go ahead for the D2H!


Reviews:

Unlike other reviews, I will go to the worst thing about my gears in my reviews first, as I'm a very critized and a negatively-thought person, hum... hum... hum...


Flare and "ghost” control

One thing that I appreciate of Nikon is usually the flare and "ghost" controls of Nikkors surpass its counterparts. The performance of the DX 17-55 mm, however, is controversial in this aspect. It could just fairy suppress flare (with some reduction of image contrast) and a number of "ghost" colour spots is visible if strong light emitted into the lens. Luckily, it won't turn the whole frame into a dead-white but that's it. Look at the optical structure, there are more than 60% of its design similar to the AF-S Zoom Nikkor 28-70 mm f:2.8D IF-ED, which is a sure winner in flare issue among its class. AF-S Zoom Nikkor 17-35 mm f:2.8D IF-ED is also a leading lens of flare control in this range. But it is another story of the DX 17-55 mm. If you evaluate its flare performance issue with a standard of ordinary zoom, it's okay. But as a top-of-the-line Nikkor, it fails, according to my standard.


Chromic Aberration

It is a DX lens, right? DX lens is specially designed to suit the demand of the image sensor, right? But why purple fringe shows up with this lens? It is not only appears at the wide-end but also the whole focal range and all aperture setting as well! With my 4.1 Mega pixels D2H, the purple fringe can occupy, in average, 2-3 pixels in width. What about those ED glasses? Where they gone? Okay, I admitted that the purple fringe matter can be corrected during post-processing. But don't you agree that it is ridiculers if we have to put in effort to correct this matter generated by a so-called "DX" lens?


Distortion

There are 2 types of distortions: spherical distortion (don't mix-up with "spherical aberration"), and perspective distortion. Put it simple. For spherical distortions, there is obvious barrel distortion at wide-end, and slightly detectable but neglectable pin-cushion distortion at tele-end. No distortion at 35 mm setting. Usually, Nikon does not put particular effort on distortion control with their zoom Nikkors. So personally I don't expect it too much. If spherical distortions really bother you, go ahead with Sigma EX series!

For perspective distortion, I just want to say it is not a fraud at all. Don't forget the actual focal length of this lens is 17-55 mm! The actual perspective won't change with the 1.5x crop factor - only the view angle will. So I have no comment on this issue.


"G" lens

No aperture ring with this lens. Traditionally the aperture ring is a symbol of Nikkor. Omitting the aperture ring on a DX lens won't cause any problem (there is no manual DSLR) but a just a matter of "crisis of identity" of whether it is a Nikkor or not.


From now on, the review will start to mention the positive side of this lens.


Out-of-focus Blur (Bokeh)

I'm not very often shooting portrait. So I don't have any lens specialized for portrait shot. If I need to shoot such subject, it is definitely the job of this all-around lens should do.

Ordinary Nikkor is sharp, not only sharp for subjects that are in-focus, but also "sharp" for those background as well! With the exception of several portrait specialized lens (such as 85 mm f:1.4, DC 105 mm f:2.0 and DC 135 mm f:2.0), Nikkor always express the out-of-focus background in a very  "hard" way. According to such philosophy, I don't expect I could get beautiful, or even natural bokeh out of this lens at first. But the result turns out that it is okay. Not particularly good but acceptable (I'll call it "natural" at least). If AF Nikkor 85 mm f:1.4D score 100 in such issue, then the DX 17-55 mm would score 70 in my opinion. Its 9 bladed-round diaphragms really do its job well.


Build Quality

Good! Solid and robust! The lens barrel is made of metal. Although the front lens elements will extent when zoom towards both ends, the huge flower-pedal shaped lens hood can cover and provide adequate protection to those extensions. Environmental seals are useful and effective. Only very minimal dust particles get inside the lens after a year of intensive use compared with my other zoom lenses. Both the focus and zoom rings are smooth and good damping. However, I do agree with many other people's opinion that the zoom ring is get too close towards the camera body when mounted. Personally I can't say the surface finishing is bad but I do miss those textures of AF-S Zoom Nikkor 28-70mm f:2.8D IF-ED.


Focus Performance

With the Silence Wave Motor, or AF-S, this lens focuses fast and quiet. No focus shift ever experienced. Full time manual focus adds features to this lens. Afterwards, I have no complaint at all.


Light Fall-off

At wide-end, there are about no more than 1/2 EV light fall-off at wide-open setting. Much improved at f:4 and equipment-detectable-only but visually unnoticeable after f:5.6. There is no visible light fall-off with medium to tele focal length at any aperture setting.


Resolution / Sharpness

Sharp! Sharp! Sharp! It is the sharpest zoom lens I have ever used! For all focal range, f:2.8 are sharp, although not as sharp as razor, definitely usable. Image contrast is slightly reduced with wide open but much improve after f:4. It is razor sharp from f:5.6 till f:13 with the best at f:8. Sharpness start to fall from and after f:16. Some people complaints it is pretty soft at tele-end. But my personal experience there is no significant difference of sharpness between the tele-end and wide-end. This may be due to the samples variant and I was lucky to get a good sample. Or just because I use D2H with relative low resolution of 4.1 Mega pixels and just could not be able to squeeze every detail out of the lens.


Overall conclusions

As I mentioned, it was this lens that made me go for DX format DSLR. So I did expect a lot from this lens. However, it is also the only lens in that time offers the best and only solution for me if I switch to DSLR. And my desire to DSLR was very high. So it was also this lens that made me willing to compromise.

One of my largest compromises about this lens is the flare issue. As this is an all-around lens to me, I need this lens to be able to shoot in very adverse lighting conditions. Pervious experience and impression of flare control by the Nikkors offered me the confidence about them. So I didn’t expect this lens will perform such badly to suppress flare. I even have to persuade myself in such manner: “Well, it’s not too bad at all. At least it won’t turn the whole scene into a dead-white!” I have no other better choice but have to made use to it.

Be honest, purple fringe doesn’t bother me very much. But I just think it is ridicules that a digitally specialized lens designed by such large optical expertise will cause purple fringe problem!

Apart from these problems, other drawbacks of this lens really don’t bother me too much. I agreed that the barrel-type distortion at wide-end may be a little bit scary to some demanding person. But I just can live with it. However, on other hand, the sharpness, the vignetting control, the constructions and the AF performance are truly make it a professional lens. If you ask me would I still choose this lens even there are more competitors on the market nowadays? The answer is: "very properly yes!" (I fact, I'm now very interested to the Tokina 16-50 mm f:2.8 DX, which is still not available on the market yet.)


Extras

Many people worrying about is it worth to invest on a DX lens given that we can't rule out Nikon may announce full-frame DSLR completely in the future. Well, let me tell you more. It is a DX lens which is not "recommend" on film camera. But they share the same F-mount and the fact is the image circle of lens can cover the 24 x 36 mm frame at the focal length of 28 - 55 mm if no filter attached. Think up yourself.

Personally, f:2.8 is not large enough for me. With the 1.5x crop factor, the actual focal length has to be shorter in order to restore the same view angle that we used to be on 135 format. One of the drawbacks is the increase in depth-of-view and become less able to "melt down" the out-of-focus subjects. We have seen Tamron introduced their 28-75 mm f:2.8 and its APS-C counterpart 18-50 mm f:2.8 with filter diameter of 67 mm with the aids of XR technology. I always have such kind of fantasy that this Nikkor DX 17-55 mm also incorporate such kind of XR technology, or thing alike, but remaining the universal professional 77 mm filter diameter to expand its aperture to at least f:2.0 or even f:1.8! Am I demanding too much?
