Basically, The strengths lie more in the telephoto range, the stability is very slow and does not guarantee consistently sharp images. I've found that even can cause vibration through the mirror moves to blurred in the D7000. Slightly better results are obtained with the Q setting, when the mirror is moved slower, or on a tripod with mirror lockup. Unusually at shutter speeds to 1/125.
at the slower S5 this error does not occur.
At 300 mm in the center almost as sharp as the 70-300 on the edge a little softer, but it is not as bad as it arrives at telephoto rather in the middle. 70mm is much softer, with the 70-300 is as sharp crack.
Compared to the 18-200, it is the opposite: to 50mm, the Nikon has the edge and is sharper in the center. From the 50mm Tamron is ahead and seems to be more sharply towards the end. The edge of the picture is similar in wide angle with the Nikon, but that is down sharply towards the center. However, the loss of detail is striking only in direct comparison because the wide angle of the rim is just as important as the center of the image and the image viewed overall, appears sharp.
Red-green CAs are eliminated from the Nikon camera, at the edges slightly blue-yellow are visible shifts, however, which can be calculated out well. With Raw converters as ACDSee Pro, Lightroom and DxO Optics Pro can handle the chromatic aberration well.
At macro shooting, it must be remembered that will be taken with 300mm, which are easily blurred despite stabilizer because often uncomfortable postures need to be taken. Overall, the macro function is not the strength of the lens.
Of course, the resolution of the D7000 is not exploited by this lens. This will apply even more so for the newer chips with 24MP. To contain recordings with the 7000 not much more detail than the S5Pro, which comes to a resolution of 8MP effectively. However, the images appear sharp and evenly and in all focal lengths, at the telephoto end more than at wide angle.
Stopping down to 8 brings in the telephoto range a little more detail, the wide angle of the effect is not so clear. The Bokeh is the wide-angle right ugly, at the telephoto end, however, acceptable.
Power consumption is slightly higher than with other lenses, but still to bear on the D7000. A battery usually lasts one more day. Much worse is the Fujifilm S5. The Tamron 16-300 of the battery during operation after an hour yet. When the camera is turned off, it takes 2 hours! According to Tamron may be that, since the lens has only been tested on actual cameras and even released for this. It can be assumed that this is D200 (same case as S5) and other older models behave in the same Nikon.
