Please remember that there are hundreds of thousands of these lenses with ring motor out there that just go on and on and on,,, Just because you see a couple of bad/broken motors and read about someone who has an issue,,, Doesn't really make me worried,,,

Not that I think the gear box design is bad it's just an awful lot of parts instead of just a few rings, as well as hear power - Speed of acquiring focus of the ring motor lenses,,,

Can we share the serial numbers of the affected three 60 Micro G AF-S here?

Mine is US 204114

It was announced on 29 January 2008 on the PMA Trade Fair and I bought the lens immediately after it was available.
In my Nikon Registration 21/May/2008 is the date of purchase, so shortly after I bought the D3.

IIRC the Motor stuck in 2015.

Both have 2xxxxx serial numbers with 6-digits, which places them in the first series made in Japan.

Pedro
I've had 2 AFS lens failures in the last 18 months.

My 300 f4 motor failed and will cost too much to fix (estimated at AUD$500). That was from underuse?


JJ, When your 300/4 AF-S ED focus motor failed, was it still possible to manually focus the lens?

Yes - but the focus throw is VERY short and as there is no infinity stop difficult as well. I had dragged it out on a supermoon night last year to find it was wasn't working - isn't it always the case when you go miles out of your normal routine....

My 60mm is a bit younger 240023

I had always felt that the manual focus action of the 300/4 AFS was inferior to, say, the old 300/4.5 ED/IF Ai/AiS.  However, recently I have found that when using the 300/4 AFS adapted to a Fujifilm mirrorless APSC camera, the ability to manually follow and set focus is excellent.  It is therefore good news that when the AF motor dies--as I think it soon will--on mine, I can continue to use the lens.

I will be happy to see a demonstration of accurate and reproducible manual focus on the 60 AF-S Micro at long distances. 100% crops please, wide open; each result must be precisely as sharp as each other and as sharp or sharper than it would be with LVAF to pass the test. I certainly cannot manual focus most autofocus Nikkors reproducibly near infinity focus.

Old Ai Nikkors are bette for MF, since quite a few of them have a more generous focus throw than AF-S Nikkors. Second, precise manual focusing at long distances is much easier with the 10x magnifier of an EVF than with an OVF.
