TAMRON - 16-300 mm F/3.5-6.3 Di II VC PZD Nikon F Cameras - Black - B016N

Product Information

At wider focal lengths, sharpness is excellent in the center, and across the frame at around F5.6-8. As focal length is increased, sharpness reduces, taking more of a hit towards the edges where it's decidedly soft above 200mm. F8 is the overall optimum aperture and will always deliver decent sharpness in the centre, even at 300mm. Chromatic Aberration

Finally at 300mm, overall performance is reduced a little, but the lens still holds up very well, especially when the huge zoom range is taken into consideration. At f/6.3, sharpness approaches very good levels in the centre of the frameand is fairly good towards the edges. The performance towards the edges of the frame doesn't improve by much with stopping down, but sharpness does reach excellent levels in the centre between f/8 and f/11. This time though, the focal length range also extends wider, from 18mm to 16mm (28mm to 24mm equivalent), bringing serious wide-angle capability to the superzoom category for the first time. A couple of millimetersimprovement over the previous Tamron 18-270mm F3.5-6.3 Di II VC PZD may not sound like much, but it makes a very useful difference at short focal lengths and the extended range now sets a new record with a whopping 18.8x zoom ratio. Closest focusing distance has also been reduced to earn the 'Macro' designation (even if it's hardly macro in the true sense of allowing 1:1 reproduction). Plenty of distortion present, with strong +3.2% barreling at 16mm, transitioning through neutral at 18-20mm, then on to almost equally strong pincushion distortion at longer focal lengths, easing off slightly to around -2% at 200-300mm. This is very noticeable in critical subjects like architecture, but easily corrected in software. Specific optical characteristics MacroThe Nikon and Canon versions of the lens have Tamron’s Vibration Compensation (VC) system, and these and the Sony-fitted model (which will be introduced at some time in the future) feature the so-far excellent Piezo Drive (PZD) near-silent and fast AF motor.

Chromatic aberration (CA) is never far away, and most prominent at shortest and longest focal lengths. It's very noticeable here around the rear wheel. 16mm, 1/200 sec, f/8, ISO 100, on Canon 7D. In coming to the soft assessment, I looked at the sample photo of the berries taken in the review, which is quite excellent for such a lens. I had expected to write at length on the subjects of vignetting and curvilinear distortions, but on the darkening of corners the lens has rather disappointed me. While some fall-off in illumination is detectable in technical subjects, in the real-life situations in which I’d expect this lens to be used that darkening is not really noticeable. Superzooms are not the best choice for bokeh fans, with modest maximum aperturesusually creating quitedeep depth-of-field.But with the Tamron's longer focal length, the narrower field-of-view gives good subject isolation, greatly enhancing the bokeh effect at 300mm, particularly at closer shooting distances. Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. In the AF 16-300mm F/3.5-6.3 Di II VC PZD lens, Tamron have employed an iris diaphragm with seven rounded blades, which has resulted in quite nice bokeh in our view. We do realise, however, that bokeh evaluation is subjective, so we've included some 100% crops for your perusal.Sell the kit you’re not using to MPB. Trade in for the kit you need to create.

Not only have Tamron delivered a lens that offers a uniquely huge zoom range, but they've managed to make one that performs well, is well specified, and is good value too. The Tamron 16-300mm f/3.5-6/3 offers a uniquely huge 18.8x zoom range, performs well, delivers good value for money and has impressive close up focus performance making this an ideal travel zoom lens. In the DSLR sector, Tamron faces superzoom rivals in every camp, and some of the designs are notably similar. Alphabetically, the Canon EF-S 18-200mm 3.5-5.6 IS looks a little behind the curve these days, though it's a proven good performer. Nikon has a history of occasional cooperation with Tamron and matches the long-end reach with its Nikkor 18-300mm F3.5-6.3G AF-S DX ED VR. The Pentax SMC DA 18-270mm F3.5-6.3 ED SDM bears more than a passing resemblance to the superseded Tamron 18-270mm. Not to be outdone, Sigma joins the up-to-300mm superzoom club with its revamped 18-300mm F3.5-6.3 DC Macro OS HSM C, and Sony has the DT 18-250mm F3.5-6.3. Angle of view Tamron has done a good job with the optical redesign, increasing focal length at both ends of the scale, and delivering better sharpness than the preceding Tamron 18-270mm F3.5-6.3 Di II VC PZD, even if there's not a great deal in it. Like all superzooms, the Tamron 16-300mm F3.5-6.3 Di II VC PZD Macro is sharpest at shorter focal lengths, and less so at longer settings. Sharpness The absolutely huge zoom range offered by this lens, hasn't compromised the size, with it having similar dimension to many 4x or 5x zooms lenses and it weighs only 540g. The low weight and compact size make this lens an ideal candidate as a walkabout lens for those times you may wish to travel light. It feels right at home on the Nikon D7100 body used for testing, and will make a good companion for smaller, more compact DSLR camera bodies as well. High quality plastics with a matte finish have been used for much of the construction of the lens barrel, and it feels reasonably robust as a result. A rubber gasket, located around the metal lens bayonet, will help to prevent the ingress of dust and moisture into the camera body.Barrelling and pincushion distortion do make an appearance, though, bending lines close to the edges of the frame at almost all focal length positions. While the barrelling at the 16mm end is not as bad as it could be in distant subjects, when we focus on closer things it is an issue. A church interior, for example, will suffer only a little, but the small bedroom of your house might take on an obviously distorted look. The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column. At the 300mm end, the angle of view is 5°20', which is the same as that of a 450mm lens on a 35mm full-frame camera. I will begin with the worst – chromatic aberration. Coloured fringing is one of the more difficult optical problems to correct after the event – and beforehand too, it seems – yet it is one of the more obvious to the eye and therefore one of the most objectionable. There are some aberrations I can live with, but I find purple and green glowing edges around high-contrast areas very difficult to accept.
