TTArtisan 11mm f/2.8 Lens for 360x180 Pans

[Bob]

Does anyone have experience with the TTArtisan 11mm f/2.8 Lens for 360x180 panoramas? My concern is that the aperture ring is "declicked" and how easy is the aperture ring moved? Thanks.

Tape it. The value you tape it depends on the sensor size. On full frame
I'd use f/16 or f/11, on smaller sensors f/8 or even f/5.6 in order to
avoid diffraction blurring.

Also tape the focus ring. If you don't want ugly tape on your lens, use
a strong black rubber band. Rubber bands cut from bicycle hoses are very
durable and don't degrade over time like most cheap household ones.

We are  using this lens on the Fuji GFX100s. We have two sets and the lenses are both pretty sharp. I made tests to find the sweetspot for the focus. It varies a lot between the two lenses. We are using f8 and the lens rings are taped.
