doh! dropped a new lens..

[tim_klimowicz]

Just got a beautiful Vivitar Series 1 70-210 FD lens from someone on

ebay - only $46!!!

 

While building a lens case out back with a heavy cardboard mailing

tube, I accidentally dropped the lens on a carpet-covered wooden deck.

It hit with a heavy thud. Now when I shake it slightly, I notice the

sound of something loose, wiggling inside, which wasn't there before.

 

I just attached it to the body and gave it a test - focus & zoom still

works fine and smoothly, and the aperture works just fine all the way

from 3.5-22 and auto (well, I assume the auto still works heh).

 

What could be making the sound? It sounds very light and metallic -

like a spring, perhaps? Could this be a problem later on if I don't

get the lens checked out?

 

Thanks,

Did you actually test the aperture or just the adjusting ring? Put it in stopped down mode and see if the aperture is adjusting all the way through.

Yeah, that's what I meant - I put it in DOF preview mode and went thru the range, and they worked just fine (of course, can't tell for sure with the auto mode - it looked the same as f/22).

 

The good news is that the ghetto lens case came out great. I just hope the lens isn't permanently damaged (somehow)..

Give it a try and see how it performs. It's possible that you're just hearing some linkage inside that you hadn't noticed before because you weren't listening for it.

 

It's also possible that you broke a zoom cam off or something more serious; but if this is the case, it probably can't be repaired for the replacement cost anyway so you might as well get as much use out of it as you can.....

I would suggest you set your camera to full manual with a two second exposure time, open it up and look through the lens from the rear as you manually trip the shutter at each aperture setting. It is quite possible that a lens will step down using depth of field preview mode but not do so properly when you try to take a picture in any other mode. I don't know how prevalent it is but I once had a lens malfunction that way.
