Operation:
It is very tired in the hand and the wide large black ring gives a nice feeling when zooming, is almost but a little too easily. Who can let go of the ring over head in shock ever realize that the zoom automatically enters (by gravity).
Even when retracted, the "lens" very powerful and makes the small body of my NX3000 an impressive camera. In the extended state, the lens is about twice as long. With the included sun visor (the well prevents the water droplets even in the rain) is shown the whole arrangement of very chic. The white paint is with the blue ring quite trendy and fashionable. Everything seems well made.
Many lay in eighth cameras yes only on the size and length of the lens. If you want to specify is well served with this trendy part.
Also the focus ring rotates easily and tired. It transfers the rotational movement to the servomotor, which really feels as if one mechanically adjusts the sharpness.
The switch for setting between autofocus and manual focus locks well.
And the pressure switch to activate the i-Function menu in the camera also works as desired. The i function only activates a menu in the camera to adjust with the rotary ring (Focus ring) lens to values such as aperture, shutter speed, or white balance.
The sun visor is easy to assemble and disassemble, but wobbles very slightly on the bayonet.
The 52mm thread is suitable for all standard lenses and filters (polarizing filters, neutral density filter, etc.) goes with me but a little tight.
Appearance:
Uncertainties and errors, such as distortion or chromatic aberration, so far I could not see in my pictures. But an absolute "Knack Focus" or color purity has the lens is not even what you can the price also can not be expected. Here the message with continuous aperture of 2.8 to 1600 would then be - hip.
This lens is just an average push.
At my NX3000 a crop factor of 1.5 results, gemäßt the DX sensor. Thus, the equivalent to a 300mm telephoto KB equivalent. For a frame-filling bird photography in a 5m distant tree, the Tele but not sufficient. Here the choice of a 600mm zoom would be more appropriate.
Luminous intensity
An example: If you want to photograph birds in the tree from the balcony with this lens, this should make at full zoom during the day in the sunshine. Is the sun gone behind the houses under the tree and the shade is hard to make it at ISO 100 blur-free images. Untwist ISO is then announced.
For nature photographers in bright light conditions, the lens is good. Who likes to work at dawn, the ISO values must screw up badly or using a tripod, what with moving animals but nothing brings.
Image Stabilizer
He works quietly, silently and brings good 3-4 diaphragms. That is, without a stabilizer must open the aperture 3-4 stages to obtain a correspondingly faster shutter speed to compensate for the lack of image stabilization.
Conclusion: good lens at a reasonable price.
