My second set goes to the people who devalue the product here, just because they can not handle it. This lens is super quiet, light, small, very AF fail, making tack-sharp images and hangs loosely the EF 50 / 1.8 and the EF 35 / 2.0 from! If you want to read the full honest test, go to the website: [...]. In fairness, I must say I take pictures with a APS-C camera to full-frame can not show its full strength of this lens. So all who do not use full-frame camera, can strike without hesitation here, you will not be disappointed. Now the lens itself. If you like the way I landscape, flowers, people and cities photographed, is ideally positioned with this little lens. I myself had the 50 / 1.8 and 35x / 2.0 but what good is my 1,8er or 2,0er bezel, if I have to stop down to get sharp photos !!! (because when I always read here 1 , 8 Aperture's the best and 2,8er light intensity is not enough, my yes is bad!) But this STM lens is already from open aperture already rattenscharf !!! Another little tip to all who want to get photographed right: if you want to depict landscapes, sunsets, rape fields, Baltic coast, ships, etc., one chooses a shutter anyway from 5 or 6 and not 1.8 !!!
Now I'm already done, I can only recommend this lens.
PS: there is an STM lens, the tube is very sensitive, you should know before the camera turns off only on MF questions and enter the tube manually (ie turn back) and only then turn the camera off.
