XF 90mm problems (no, not LM rattle)

[rrrrrichard]

My brand new XF 90mm has two serious issues. I'm wondering if anyone else has seen either problem or if I'm missing something. I have a few other XF lenses (16mm, 27mm, 35mm2.0, 56mm) and none of them exhibits these issues.

 

(1) When the camera is turned on, the lens makes an irregular but unceasing sound that seems to me a bit quieter than, but otherwise identical to, the normal focusing sound. The camera (X-E2s, v1.01) is in AF-S mode with Pre-AF OFF. Am I missing a setting that might cause this?

 

(2) The aperture ring's position is not being properly communicated. When the ring is turned to f/2 the camera indication (EVF and LCD) sticks at f/2.2. It can be coaxed into f/2 by repeated tries. Furthermore, the ring always fails to register the first third-stop when turned from the last stop at the end of its play (f/2 or f/16). As the ring is turned more, it continues to be one-third stop off (with respect to the camera's indicated aperture).

 

So, I guess back to Amazon.

1. is normal. thats the sound of those AF motors 

 

2. is not but probably can be fixed by Fuji (if the lens is optically very good I would think about that option)

I appreciate your help but I'm puzzled. Why is it trying to focus?

I think the noise is normal, and comes from some magnets inside the lens.

 

Regarding the aperture, it's definitely not intended to work this way, so you do well to send it back to Amazon

Thank you both. I just now requested the Amazon exchange.

I recently acquired a used copy of this lens. I haven't noticed problem 1, but I did have problem 2, exactly as you have described. I returned the used lens and purchased another used copy which works great.

Got my replacement from Amazon yesterday. Chattering focus motors on this one too, but aperture ring issue gone. Yay, I guess, though Fuji QC or (worse) their design tolerances are suspect. Wish I could have the Fuji love without the Fuji anxiety.
