Lens feels dibasic.
On the camera itself (EOS700D), I have compared images made over the 18-135STM Canon.
2sec-self-timer, center AF point, ISO 200, focal length about 16 or 18mm, 30mm, 50mm, 80mm, 135mm.
At times, the lens is minimal front, but it disappointed sehr.keine sharpness where you wish to participate, although I have voted center AF point.
At the edges still more uncertainty.
1: 1 View in Lightroom each synchronized in the cut .....
These STM constantly pumps quieter than PZD.PZD in video mode on, STM optimal video settings during AF.
About 135mm focal length F6.3 starts here already. the Canon 18-135STM is here indeed the end, but only f 5.6.
So 135-300mm F6.3.
I bring the lens back and give instead more money or as much money out when needed for a Canon 70-200 f4 IS or new, and have the same focal length, at least a 70-200 f4.
2Stars therefore, due to blurring, focal length aperture option, value for money and AF-taps.
My opinion
