Got some sticky goo on the lens barrel when it was out. While wiping it off I gripped it too hard with the cloth, ''dislodging'' the lens barrel. It's still in place, just loose!!! It wouldn't retract. After ''fiddling'' with it, rotating the lens barrel (and the sliding middle ring), it will now open and close correctly but the rectangular window is at an angle and interferes with the image coming through the lens. The printed markings on the lens are not top and bottom, as they should be) but sort of off center (''zoom'' at 4 o'clock and ''34.8mm'' at 10 o'clock.
Thoughts?!? I'd like to reseat the lens correctly if possible.

You'll need lots of patience - a nice day in the garden, a new roll of kitchen wipe and a bottle of methylated spirits. THEN moisten the kitchen wipe with spirit and wipe an area taking care not to over wet and get spirit in radio. the wipe will pick up some of the goo but not much, so..............a new piece of wipe and just keep going. It took me about 2 hours, a quarter bottle of spirit and a whole roll of wipe but is was worth it! Good Luck!
Its very unusual for alcohol to leave a sticky residue, however try wiping over with vinegar, or even petrol that is for lighters. Put either on a cloth, (don't soak the cloth, just dampen it) and gently wipe, leave to dry. try that.
Hi, not sure if you still have this issue. I have just decided to look into it again, as I had a lot of focus problems with my Sigma 70-200mm HSM lens. Since there is no Sigma support here in Beijing, I took a look - and fixed it.
Here is what I did: On the front of the lens barrel is the rubberised focus ring. This can be removed (gently ply it away from the barrel by sticking a flat bit (or plastic letter opener) between the barrel and the rubber grip. It will come not entirely loose, so you need to work your way around the lens. Keep doing that until you moved it about half way forward. At this point two fixing screws become accessible on the barrel below.
In my case, one of the screws had come loose and that blocked the focus ring from turning, as the screw was blocking rotation in the access hole on the barrel.
Hope this helps others. Simple to fix, if you know how.
Turn the device off.
Disconnect any AC adapter.
Dampen a cloth with some dish-washing liquid.
Wipe the surface -- the object is *NOT* to get any liquid INSIDE the enclosure.
So, wipe with that damp cloth, and immediately use a dry cloth to absorb any dampness.
The problem is that the lens has become stuck in the barrel
after dropping it. There are some DIY solutions you could try, but the
probability is that you will have to get it fixed by a professional.
these at own risk as it may further damage the camera.
try connecting your ac adapter or usb cable.
Try holding the
shutter button while switching on the camera.
Look at the lens ,
and if some of the lens 'circles' is misaligned or not concentric then
try wiggling it (while holding camera lens down).
pushing or pulling the lens when it extends but this is risky as it may
cause the lens barrel to slip out of its guidance system.
way to do this is to place the camera lens down on a hard surface and
then power it up. Be sure to use a soft cloth or something similar as to
not scratch your lens or casing. Let the lens push the camera up and
down a few times and sometimes the little resistance provided by the
camera is enough to get things going again.
Try hitting your
camera near the lens on the body with the soft tissue on the palm of
Other than that , I would take the camera to a repair
center for a evaluation to see if it would cost more to repair than to
replace the camera.
If it is still under warranty I would suggest
you take it in before trying any of these steps and remove any
off-brand batteries or accessories as some stores are really fussy about
warranty repairs on camera's with non-brand accessories.
A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it. There are many non-invasive techniques that people have come up with to accomplish this. Some may be seen at this blog article. You can also open the lens barrel up to fix the covers, but only as a very last resort. The article also gives examples for this type of procedure.
Simple use soft lint free cloth like old drying up cloth, you need about half a cup of methalayted spirits,can get this from any hardware store. poke finger into cloth dip into meths proceed to rub sticky coating off binoculars. you will need to keep changing to a new peace of the cloth as soon as it gets coated with the sticky black stuff off binoculars. keep dipping into meths eventually after say 6 rubs in a particular area you will see and feel a nice hard black plastic, continue all over effected area then finish off with any window cleaner polish until cloth remains clean.STICKY COATING IS NOW GONE IT WAS INFACT A COATING PUT ON THE BINOCULARS TO MAKE THEM NONE SLIP. job done. regards GER8
