Opening the package: the objective is of excellent quality and well finished, the beautiful book.
First tests and first surprises: the device comes to the development but the images are blurred even a speed greater than 1 / 320th! Front-focus enormous confirmed by measurements on Reikan Focal Pro. Despite the calibration, depending on the distance taken images are blurred. I said that this is not my first f1.4 lens and a 50mm f1.4 with, no worries. After many attempts, I have to go to Clearly, this objective clearly has a problem.
Request for return and a copy is 2nd receives the next day (! Bravo and thank you a thousand times the efficiency of Customer Service !! Amazon and re-belotte with Chronopost would be left without waiting for the rest if my neighbor had not stopped in time ...).
Hopeful I open the 2nd package. Mounting the camera .... bitter disappointment. The AF in the vamp and mouline empty without managing to do the development. And when he gets there, half the time, the image is completely blurred.
After many tests I go to lévidence, this exemplary 2nd is worse than the first.
Therefore I also returns and asks to be repaid.
I know that Sigma had major quality control problems last year with the launch of this objective and that many of them were defective. I therefore assumed that Amazon sent me copies are unfortunately part of that lot.
In conclusion: probably very good goal, provided of hitting a good copy, which is unfortunately not my case.
So I go my way and has suddenly opt for the f1.2 Canon. The price difference is astronomical but if satisfaction is the price ....
