AboutDavid Barry Expertise I have a lot of experience in most traditional forms of photography, so I`m quite knowledgeable about things like camera types and formats, techniques, exposure, film types, colour, filters, lighting, standard colour and black and white developing and printing.
I do not make recommendations about brands or models, and I am not a camera technician so I may not be able to tell you what is wrong with your equipment if it`s not working .
I also know a little about digital photography and imaging with scanners and digital cameras, so ask me and I will answer if I can.

Expert: David Barry Date: 4/5/2006 Subject: Dust in my zoom lens
Question I see particles of dust inside my Albinar ADG Zoom lens. Is this a common problem? Can I take the lens apart and clean it myself?
Answer I don't know if it's common for the Albinar make, but it's not something that should occur if you bought this lens new. A well made lens should not be showing such problems, so maybe a sign of poor quality control in the factory. Maybe a cause for you to make a complaint to the factory or claim for warranty replacement.
If you bought it second-hand, then it may be a symptom of neglect or poor storage by previous owner, and you may not be able to make such a claim (warranty may not exist or have expired).
I would NOT recommend you fixing it yourself. Lenses require fairly specialised skill to repair. Look for a good reputation optical repair technician to do this sort of stuff, if you can't get the Albinar agent or factory (whoever / wherever they may be) to sort it out.
