I just received a Olympus 35 sp and the lens elements appear to be a bit loose.
 
I inspected under the top and bottom plate and it does not appear to be the attachment of the lens to the body.
 
Each ring of the lens has a little bit of play re

what happens sometimes is that the grese dries or migrates out of the focusing helical.  this is usually a pretty loose fit to make room for the grease, so when the grease disappears it feels loose.
 
in leaf shutter rangefinders, there is anothe

I have several cameras with the same symptom of wobbly rings. It is sometimes not an issue of the attachment of the lens to the shutter base plate and not an issue of the attachment of the shutter base plate to the camera body. Every ring itself has a bit

Barny,  I have been looking at my Olympus SP which is in pristine condition. I had never noticed it before, but I can wiggle the whole lens assembly maybe 2/10 mm displacement at the front.  By move, I assuem you mean play while remaining at a deten

Mel wrote Some play is necessary to accept tolerances in manufacture of parts. This may be right, but what seems more important is that without any play wheels, rings, cams wouldn't move, revolve, rotate, turn. Try your car's front wheels:

Many of my Olympus have had the problem Rick mentions. If he whole lens barrel wobbles as a unit peel back the two pieces of leatherette on the front and tighten the four screws holding the plate to the camera. Also, I have been using #675 zinc/air hear

thanks everyone.
the wobble is in the lens. I peeked under the top and bottom plate to  check the attachment to the body already.
I'm using the #675 hearing aid battery with some wire to hold it in place. It works great and compares well with my g

If there is wobble between the front and rear half of the focusing helical, it needs to be re-greased.  There shouldn't be enough play in the aperture or shutter speed rings to be particularly noticeable, and even if there is it won't hurt anythin
