Q
Is the aperture ring de-clicked?
A
The ring is on your lens dude.... 
Q
what is the difference between ND 2-32 and ND 8-128 ? and does the 67mm works for tamron 28-75 for sony ?
A
The amount of stops is the difference. It’s basically 2-5 stops, and 3-8 stops. 2-5(2-32) is perfect for photography. 3-8(8-128) is perfect for video. I do both so I got both and they both are PERFECT. 
Q
The difference between APS-C, full-frame, 4/3 sensor
A
  1. Adapting APS-frame lens to full-frame camera, it may generate vignetting, some cameras could correct it by adjust APSC, please contact us and provide your lens&camera model to check the way to correct it.
  2. Adapting full-frame lens to APS-frame camera (i.e: large format to medium format, medium format to 35mm, 35mm to micro 4/3) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. and it will magnify the focal length by 1.6 on Canon, 1.5 on Nikon and Sony,2.0 on M4/3 camera.
