Nikon D60 Optics
The Nikon D60 ships in kit form with an updated version of the Nikkor 18-55mm f/3.5-5.6 lens that originally came with the D40 and D40x kits. To better compete with models from brands such as Olympus, Pentax and Sony that have built-in image-stabilization, the new D60 kit lens comes with Nikon's excellent Vibration Reduction (VR) technology to help compensate for camera shake. We tested a sample of the Nikkor 18-55mm f/3.5-5.6G ED AF-S DX VR on SLRgear.com. Optical performance is so-so wide open, but the lens is capable of very good sharpness if stopped down one or two f-stops, and the added image stabilization should come in handy in low-light situations. While sharpness wide-open is only average, this new kit lens performs better overall than the original, non-VR 18-55mm, and is enormously better when it comes to flare: The previous version was subject to rather extreme veiling flare when shooting high-contrast subjects under bright conditions.
Kit lenses work well enough for most consumers, and serve their purpose, getting you started without breaking the bank; but a big part of the attraction with SLRs is that you can easily trade up to a better lens when your finances improve, and extend your reach to wider angle, telephoto, or macro photography just by adding to your lens collection. The 18-55mm VR lens that comes with the D60 will do a fine job until such time as budget and desire lead you to start building a lens collection.
Like the Nikon D40 and D40x before it, the D60 drops support for the older autofocus lenses whose focus mechanisms were driven from the camera. These lenses have what looks like a little screwdriver slot on their mounting flange that couples with a protruding, screwdriver-looking shaft on the camera body. A motor in the camera body thus drives the lens mechanics to adjust focus.
More recent Nikkor lenses have motors built into the lens body, which tend to be both faster and quieter than the old-style drive system, as well as allowing the camera body to be lighter, smaller and cheaper. These newer lenses carry an AF-S or AF-I designation in their name, and are the only types of lenses the D60 can autofocus with. CPU-equipped lenses lacking built-in focus motors can be used in manual focus mode, and type G or D lens types will also support full 3D color matrix metering for more accurate exposures, particularly when flash is being used. (You can tell CPU-equipped lenses by the set of five electrical contacts arrayed on the side of the lens flange.) The table below (courtesy Nikon Inc.) tells the full story of lens compatibility for the D60.
The lack of an onboard focus motor is a key feature distinguishing the D40, D40x and D60 from the D80. If you need to use older lenses (or a lot of Nikon's current line of prime (non-zoom)) lenses with your DSLR, you need the D80, D200 or D300. This is a factor that could turn away current Nikon shooters, but it makes sense for an entry-level camera like the D60. Dropping the AF motor greatly helps with size and weight issues, and probably battery drain as well. Newcomers to the SLR world are likely to be perfectly content sticking with AF-S lenses, and all of Nikon's digital-specific DX lenses are AF-S models, providing a pretty wide range of options.
While the D40, D40x and D60 carry over a lot of the capabilities of the D80, their autofocus system is one area where cost-cutting has had a noticeable impact. The D80 has 11 active AF points, but the D60 has only three, arranged horizontally across the frame. With the more limited AF array, the D60's ability to track moving subjects will be less than that of the D80, but the 3-point AF array isn't unreasonable to find in its price bracket.
This is one area where the interests of novice and more experienced shooters may actually converge. Both would benefit from the D80's more sophisticated AF system, and the argument could be made that novices actually need a better AF system than advanced amateurs, as they'll be less accustomed to paying attention to what the camera is focusing on. That said, it's not too difficult to check that one of the 3 AF areas is covering your subject, and it's a relatively small step up to learn to aim the camera and lock focus.
The Nikon D60 offers pretty well all the focus options of the D80, the main difference being that options for setting the focus mode are presented on the LCD screen, as opposed to a little single/continuous/manual focus switch on the camera body itself. Many Nikkor lenses also have an Auto/Manual focusing switch on their barrels. If the switch on the lens barrel is set to "M," focusing will be under manual control, regardless of the setting of the switch on the camera body. Most AF-S lenses with the built-in Silent Wave focus motor let you manually focus the lens at any time, regardless of the camera's focus setting, so there's less need for a body-mounted focus-mode switch: The menu selection should do fine for most users.
To select between the three types of AF, you just navigate to the Focus Mode option on the camera's shooting display (or to the identical Focus Mode option in the Custom Settings Menu system) and choose between AF-A (Auto Servo), AF-S (Single Servo), and AF-C (Continuous Servo). Manual focus is the fourth option. Single Servo simply means that the camera sets focus only once, when the Shutter button is first pressed halfway, and is best for still objects. Continuous Servo means that the camera continuously adjusts the focus, as long as the Shutter button is halfway pressed, and is best for moving subjects. The Auto setting (added to Nikon's D-series SLR line with the earlier D50) lets the camera select the servo mode, depending on the movement of the subject.
The Nikon D60 is similar to the D40 and D40x in how it behaves in out-of-focus conditions. Some SLRs will let you fire the shutter in Continuous Servo mode if the lens hasn't achieved focus, but not in Single Servo mode. The D60 never fires the shutter if the lens isn't focused. (Unless of course, you have the camera or lens set to manual focus operation.) This more restrictive shooting could be an inconvenience to more experienced shooters, but will almost certainly be a benefit to novices, as the camera itself will guard against capturing out-of-focus images.
Focus can be confined to one of the three specific focus points in both Single Area mode, and in Dynamic Area which offers focus tracking. Single Area AF simply means that the camera sets focus based on the specific area you've designated. Dynamic AF employs all three of the autofocus areas. When Dynamic Area focusing is enabled, the camera first focuses on the subject in the chosen focus area. After the camera has initially "locked on" to the subject, if it moves to a different AF area, the camera will shift its focus to "follow" the subject. This is great for irregularly moving subjects. (Sports and kids come to mind.) In both Dynamic and Single Area AF modes, you can change the primary focus area using the right or left directions on the Multi-Selector pad. Closest Subject Priority is a third option, selected via either the AF-Area mode option on the shooting screen or by a custom settings menu item. Closest Subject Priority means that the camera will focus on the closest object that falls under one of the three focus points.
There are two methods by which you can lock focus with the Nikon D60. The first is via the Shutter button, placing your subject in the selected focus area, halfway pressing and holding the Shutter button, then realigning the composition and firing the shutter. Alternatively, when using Single Servo AF, you can press the AF-L/AE-L button to lock focus (and exposure, unless the button is set for focus-only in the Custom Settings menu) after having initially established it by half-pressing the shutter button. Keeping this button pressed will maintain the focus and/or exposure lock, even if the Shutter button is released. This lets you recompose the photograph without having to keep your finger on the Shutter button, but rather on the AE-L/AF-L button instead. (Reducing the chance that you'll accidentally trip the shutter when you don't intend to.)
There are several options available for the AE-L/AF-L button, which can be set via the Custom Settings Menu. You can program it to lock either focus or exposure separately, or both together (the default). You can also change its operation so a single press locks and holds the exposure setting. (No need to keep the button held down.) Finally, you can set the AE/AF lock button so it alone controls the autofocus system, meaning the autofocus won't actuate when the Shutter button is half-pressed, only when the AE/AF lock button is pressed instead.
If you're a novice user considering purchasing a Nikon D60, and all this focus/exposure lock mumbo-jumbo sounds confusing, don't let it worry you; the camera's default operation is very straightforward, but the availability of features like these is really liberating for more advanced users.
Like past Nikon SLRs, the D60's AF-assist light is a bright incandescent bulb that emits from the body near the handgrip. We thought to call particular attention to it, because some competing cameras (notably the Canon Digital Rebel and Sony Alpha series) use the flash as an AF-assist light. This would be fine, but they also require that the flash be used in the exposure, so there's no way to have AF assist for available-light shots. The D60 doesn't have this limitation.
Nikon D60 Anti-Dust Technology
The Nikon D60 includes a two-pronged approach to fighting dust. The dust reduction system previously seen on the D300 digital SLR has been adopted for the D60, where the optical low pass filter over the sensor is vibrated to shake off dust. Nikon has coupled this with what it is calling the "Airflow Control System". In essence, the camera's internals have been designed so as to control the flow of air - along with the dust the air is carrying - when the shutter is triggered, channelling dust particles away from the sensor.
Despite the new dust cleaning features, we haven't seen an automatic system yet that's capable of removing all dust. So while this is a nice feature to have, don't be fooled into thinking that you won't have to either learn how to clean your sensor or send the camera in for cleaning.
Everyone understands that lenses sometimes get dust on them and need to be cleaned, and there are a lot of lens-cleaning cloths, solutions and other accessories on the market that work well. BUT, what do you do when your sensor gets dusty? Dust specks on the sensor tend to show up when shooting at very small apertures, appearing as dark blobs on your images. They're distracting at best, a terrible nuisance at worst, if you end up having to retouch every image to rid of them.
Most of us are naturally leery about the idea of poking around inside the delicate innards of our DSLRs to wrestle with recalcitrant dust specks. Gently blowing the sensor surface (actually, the surface of the anti-aliasing filter) with compressed air gets rid of some dust, but there's invariably a lot that just stays stuck, no matter what. So what do you do?
If you've got dust specks on your sensor (and sooner or later you will), you're going to need to clean it. There are a lot of products out there intended to address this need, but a distressing number of them work poorly (if at all), and many are grossly overpriced. Advertising hype is rampant, with bogus pseudo-scientific jargon and absurd product claims run rampant. And prices - Did I mention prices? How about $100 for a simple synthetic-bristle brush?
So how do you know what product to use?
We don't pretend to have used everything currently on the market, but can tell you about one solution that worked very well for us. The "Copper Hill" cleaning method is straightforward and safe, and in our routine usage here at Imaging Resource, highly effective. Better yet, the products sold by Copper Hill Imaging are very reasonably priced. Best of all, Nicholas R (proprietor of Copper Hill) has put together an amazingly detailed tutorial on sensor cleaning, free for all.
Sensor cleaning is one of the last things people think about when buying a d-SLR, but it's vital to capturing the best possible images. Take our advice and order a cleaning kit from Copper Hill right along with your d-SLR, so you'll have it close at hand when you need it: You'll be glad you did!
(While they've advertised on our sister site SLRgear.com from time to time, we receive no promotional consideration from Copper Hill for this note. We just think their sensor cleaning products are among the best on the market, and like their way of doing business. - We think you will too. Check them out.)
Kit Lens Test Results
Pretty good performance with the 18-55mm VR (Vibration Reduction) kit lens.
The Nikon D60 comes with an 18-55mm VR kit lens, which is a fairly average optical zoom range of ~3x for a kit lens. Details are reasonably sharp across the frame at full wide-angle, with low levels of coma distortion but some noticeable chromatic aberration and slight blurring in the extreme corners. Results at full telephoto are also quite good, though again, some blurring is noticeable in the corners of the frame, especially on the left-hand side. Overall performance is probably a bit above average for a kit lens.
A small area (for an SLR kit lens), with slightly soft details. Flash throttles down well.
|Standard Macro with 18-55mm VR
|Macro with Flash|
As with zoom performance, the Nikon D60's macro performance will depend entirely on the lens in use. However, with the 18-55mm VR kit lens set to 55mm, the D60 captured a small (for a non-macro SLR lens) minimum area measuring measuring 2.81 x 1.88 inches (72 x 48 millimeters). Details were a bit soft throughout the frame. There was also some additional softening in the corners from the lens. (Most lenses have some softening in the corners at macro distances.) The D60's flash throttled down for the macro area pretty well, resulting in a good exposure. Bottom line, a very credible macro performance for an inexpensive kit lens.
Moderate barrel distortion with the 18-55mm VR kit lens, though low pincushion.
|Barrel distortion at 18mm is 0.8 percent|
|Pincushion at 55mm is less than 0.1 percent|
The Nikon D60's 18-55mm VR kit lens produced about 0.8 percent barrel distortion at wide-angle, which is about average among the cameras we've tested, and noticeable in its images. At the telephoto end, the less than 0.1 percent pincushion distortion is quite low and not nearly as noticeable. This is the tendency for the lens to bend straight lines outward (like a barrel -- usually at wide-angle) or inward (like a pincushion -- usually at telephoto).
Moderate and bright at wide-angle, but low at telephoto with the 18-55mm VR kit lens.
|Wide: Moderate but bright,
top left @ 200 percent
|Wide: Quite bright,
top right @ 200 percent
|Tele: Low and dull,
top left @200 percent
top right @200 percent
Chromatic aberration in the corners with the Nikon D60's kit lens is pretty evident (we'd call it on the high side of "moderate," or "noticeable") at the 18mm setting. It's less distinguished by its width (6-8 pixels) and more by its brightness. At 55mm telephoto, this distortion is much lower and hardly noticeable. (This distortion is visible as a slight colored fringe around the objects at the edges of the field of view on the resolution target.)
Some blurring in the corners of the frame at both zoom settings with the kit lens.
|Wide: Soft in the
corners (lower right).
|Wide: Sharper at center.|
|Tele: Slightly soft in the
corners (upper left)
|Tele: Sharper at center.|
The Nikon D60's 18-55mm VR kit lens produced soft corners in a few shots. At wide angle, corners were a bit soft, with the right-hand side being softer than the left. Sharpness improves fairly rapidly as you look toward the center of the frame though, so this isn't a particularly significant shortcoming. At telephoto, corners showed less blurring, this time with the left side being the softest, while the center was still fairly sharp. Not a bad performance for a kit lens.
