Sony 35mm 1.8 FE slowish aperture blades

[Shawn D]

I noticed that the aperture blades on my Sony 35mm 1.8 fe seem a little sluggish on my A7II. They are perceptably slower than my Sony 85mm 1.8 fe and my Sony 50mm 2.8 fe on the A7II.

The 35mm blades seem to move faster on my A6000.

I was testing it the following way: With back button focus setup and liveview effects off, I set the aperture to 5.6 and press the shutter button halfway while looking into the lens.

Does anyone have this lens and can check?

Thanks!
