Review on 📷 7artisans 7.5mm F2.8 II APS-C Manual Fisheye Lens for Sony E-Mount Cameras: NEX-5N, NEX-7, NEX-3N, NEX-5T, a3000, a5000, a6000, a3500, a5100, a6300, a6500 by Citylife Padilla

This is a manual lens, meaning you need to set the aperture and focus manually. It's also APS-C. On my full frame Sony a7 I have to set the sensor to APS-C in which it works great. It also works fine on my a6300. I enlarged a few photos to check for distortion or aberrations in the corners and found the glass to be of good quality. One thing I found is that setting aperture priority for the camera body still allows for some automatic adjustments, since the body controls the shutter speed on Sony. Nice too, since Sony is mirrorless you can see the effect of different aperture settings as you change the value. For the money, and for a lens that won't be your main lens, you can't go wrong.
