It might be a good lens, if you can get it in focus. Was stiff, now I have to squeeze it to change focus. Before you could just turn it, now you have to apply pressure to change the focus.

If you have weak wrists, I wouldn't recommend it.

Make sure you turn the IS to 8mm, or off. Otherwise, every picture will be blurry.

Somebody else, had the same problem, the focus ring got loose. If, only I had a box to send it back in. She threw a box out last time she cleaned, that I could of used.

They shipped it in a shitty envelope. So tape it back together? Give them even shittier packaging.

Adorama sucks. They don't respond to selling quotes, to sell something to them, and they ship in shitty packaging.

Optically, it's fine, but the focus ring is shit. Now, I have to send it back.

Venus Optics Laowa 4mm f/2.8 Fisheye Lens for Micro Four Thirds does that lens work? Costs more, but you can order from B&H, or pre order.

Printing the return instructions + label, maybe. Printer paused. Clicked the button, and it printed.

I'm lazy, so I'll have UPS package it for me, might have to pay.

Defishing sort of works. The colors are better in the first image. Better to edit the JPG then the RAW file then. If you are to lazy to figure out how digiKam works. Looks like, I might need to update that too. My lens isn't in it's database.

Instead of doing it manually, use the Samyang 7.5mm auto correction, on the JPG of course.
