Loose Sounding 28-70 2.8 AF-S zoom

Just wondering if any other owners of the Nikon 28-70 2.8 zoom have any issues with the lens sounding or feeling loose. Let me explain.

I am new to this lens and purchased on that was regularly serviced every 2 years with no issues during its lifespan. However I notice a

few things:

 

1. The focal length ring when you turn it gives off a light grinding noise as it slides between 28 and 70. It's smooth but a little noisy.

 

2. The focal ring I believe is a tad loose. When I hold the lens and turn it upside down and right side up the insides sound a little loose.

Like a few knocks and pings. There is also maybe 1/2 mm of play in the ring.

 

Any other owners experience this? I mean, if I take my brand new 50mm 1.4 AFS prime and lightly rotate it or shake it I feel movement

inside as well, so I am not sure what to make of it.

 

I have a Nikon lens/camera friend whose been repairing cameras and lenses for 40 years so I do plan to let him tune it up, but before I do

I was hoping to hear from some fellow owners.

 

Much thanks!

<p>Grinding is not normal. My lenses don't rattle either but I know nothing about the 28-70mm. Did you just purchase it? If you did, can you return it? Is your friend a certified repair person?</p>

<p>I have the 28-70; no rattle, no noise, nothing loose. What Elliot said...can you return it?? If not, I would have it looked at by a <strong>certified</strong> repair person. Good luck. Joe</p>

Yes, my guy is an authorized Nikon

repairman. If there is something wrong

he would tell me and fix it. He made a

call to another tech who is a little more

experiened with 28-70s and he said a

little tiny bit of rattle is no big deal. The

focal ring instead of having a feint

shhhhh sound as you rotate has a feint

soft more of a grindy type sound it's not

rough. It's smooth, with just a different

sound. I'm not sure if because the lens

is so large and thick that perhaps it

comes with the territory. If a Nikon tech

said so I'd never think of it again. But

something tells me something inside

the lens might be a tad loose. I don't

want to return it. If it needs tweaking I'll

deal with it. The seller has even offered

to come to me with his other 28-70 and

let me compare the two. I also saw a

recent receipt with matching serial from

Bikon that said the lens is perfectly

usable. Any squeaks are due to the

AFS motor which can be replaced. One

way or the other I will reach a

conclusion, even if I have to pay or split

a repair bill. The lens is sharp and

bright, so I know the optics are fine.

Just hoping another 28-70 owner could

describe some of the idiosyncrasies of

this lens. Thanks!
