Dirt on inside lens. DMC ZS5. How to remove? Is there a repair manual out there?

SOURCE: dirt inside back lens element

The dirt has gotten onto the front element of the rear lens group. You do not want to try partially disassembling the lens to clean it. Either Tamron or a good camera lens repair technician should be able to perform what is called a partial internal CLA (cleaning, lubrication and adjustment) of just rear portions of the lens for fairly cheap. Alternatively you may be able to pick up a used Tamron 28-200 in excellent condition for less than the repair cost of your current lens. If successful, then you could turn around and sell your 28-200 for parts or sell it to someone who knows how to service it.

That model has a removable lens; take it off, look for the hair, and blow it off.

Gently tap the lens with a stick and see if the dirt will fall to the side. It may of course migrate back, but as long as it doesn't stick to the lens, it will be out of the way for most pictures when the aperture closes. If it is stuck to the lens, have it professionally cleaned, OR take consulation in the fact that closer dirt is to the "optical center" of a lens, the less effect it has on normal pictures- pictures of bright objects are different though

If you need the cable for downloading pics, you can do the same with a card reader. Readers and replacement cables can be purchased at stores like Walmart, Best Buy, Kmart.

I'am afraid the only way to fix this, the whole lens housing must be dis-assembled taken apart and cleaned in order to address this, to get a professional will be expensive but you could ask for an estimate. The only other option is to attempt the repair or find somebody you know that is very good mechanically.
