Is focusing on the FE 28/2 loud/rough?

[kona]

Is the focusing/aperture action on the FE 28/2 louder than other FE lenses? Or is this unique to the used copy I just purchased?

 

Focusing at f2.0, my copy is surprisingly loud with a bit of vibration/roughness. Its similar to screw drive lenses. Considerably less stealth than any of the other FE lenses I've used (55/1.8, 90/2.8, 28-70 kit). I'm considering returning it, but wonder if another (new) copy would be similar.

 

Others have a similar impression? Any thoughts appreciated.

My copy is very quiet. I would say that it isn't noticeably louder than the copy of the 35/1.4 I had. To put it into perspective, I have shot my very light sleeping daughter with it up close without issue.

The 28/2, 55/1.8 and Batis 85/1.8 all produce a slight lock on noise on acquiring focus

The FE 28/2 is completely silent acquiring focus @ f2 as I go through the stops  2.8, 4 etc it's makes the acquisition click.

FE 55/1.8 same but a tad quieter but makes the acquisition click at 1.8 right through

85/1.8 same click on acquisition right through.

 

If I put my ear right up to the LCD the motor on the 28 is louder than the 55 which in turn is louder than the 85 which is almost silent

 

Absolutely NO grinding noise here.

I had a similar issue with my 55/1.8. It steadily got worse until there was a mechanical failure and it would no longer focus, auto nor manual. Luckily it was still under warranty and it was repaired at no charge.

Quick point for thought none of the Sony or Sony/Zeiss lenses have any helicoid or screw focus systems in place. They use electro-magnetic systems in tracks; therefore there is no true manual focus, manual focus is "by wire". This is very out of the box design by Sony. Sony lens focus should be near silent. You can see the design difference on the LENS RENTAL DOT COM website Roger Cicala and his team disassembled on contiguous days a Canon 35mm f1.4 ii and a Sony Zeiss 35mm f1.4 focus systems out in the open and compared.

What I left out of my earlier post is that there are no motors in any Sony lens.
