MINOLTA 16mm CAMERAS From their modest beginnings after World War Two, the Minolta subminiature format rose to become the most popular Japanese 16mm, still-picture manufacturer and helped Minolta establish itself as a major player in the photographic industry. The revolutionary Minolta cassette is the closest the subminiature market ever came to a "standard" 16mm film format and it was copied by many other camera companies, even outside of Japan. With the exception of the Minox cassette, it is the long-distance runner of the submini world; Minolta manufactured and sold its film cassettes until 1995, and replicas are still being made in the Ukraine and China (?), today. Fortunately, even the older cameras are still very useable since the Minolta cassette used 16mm film (which is still readily available), and they did not require perforations in the film to advance the film. They are very easy to reload. Check out The Darkroom for details.
The original Minolta 16mm camera was designed by the Konan Institute and used the original Konan cassette. This cassette will not fit in any of the Minolta cameras -- or at least cameras with the Minolta name, since Minolta ended up making many cameras with the Konan name. Basically, Minolta bought-out Konan. When Minolta took over, they redesigned the cassette using black felt for the light trap. There were actually several versions, nearly identical. The first was metal, but this was soon replaced with the more standard plastic type -- of which there were several versions. Minolta made two plastic models, identical except that on the second version a notch or indentation was cut into the cassette bridge to make it easier to break off the film take-up lobe for processing purposes. (If you have the newer version it's a good idea to fill in the notch with a little epoxy to make it last longer.) To complicate matters even more, similar cassettes were made by other companies, such as Yashica (which sold a camera that used the Minolta cassette), a company called FR (which sold the film and offered processing), and others. The Minolta cassettes are fairly easy to find today, and will fit in all of the cameras on this list. They will NOT fit in Mica and Konan.cameras. To top it all off, there are even bogus Minolta cassettes being sold. For more information check out the NEWSTAND.

SOURCE: blob on photos

Sounds like you have your "blob" on the actual CCD sensor in the camera. There are special "cleaning kits" to remove dust etc. from the sensors without damaging them. I would not suggest trying a "home-brewed" system of cotton swabs, isoporpyl alcohol, and a can of compressed air, unless you were very well versed in this operation. A scratch on the sensor will ruin the camera. Have a qualified shop do it, or buy the sensor cleaner kit, if you want to be safe.

The only problem with doing this repair yourself, is that upon re-assembly you will need the Nikon software and hardware to readjust and calibrate the lens. Try sending it to PhotoTech Repair Service in NYC. They are Nikon authorized, and can do the repair under warranty if you still have it. Also if you join they're facebook page, they will give you a 10% discount.
Here is the facebook page link, it has everything you need to send it in.

Clean inside lens fungus

If you realy have fungus in your zoom lens, you can't do anything. If it does not show on the pictures, just keep the lens dry. (use silica gel) If you want it it be repaired, it will cost more than an new lens.

Cleaning dust deep inside a 18-200mm vr

Unless you have a lens collimator and other gear needed to reassemble the lens, don't even think about taking it apart yourself. If gentle shaking and tapping doesn't dislodge it, take the lens to a reputable camera shop and have a trained professional clean it.

How do I disamble a TAMRON 28-80 aspherical lens. The inner lebs is cloudt/dirty

Sorry, you don't. It's a professional job only as you need lens calibration equipment which you won't possess.

In any case, if there's a cloudy element it's probably lens fungus. Lenses which are badly infested are best discarded as they're totally uneconomic to repair unless they are very high value specialist items. Yours isn't.

Sadly you are wasting your time as even if you can repair the lens element you lack the lens collimation equipment needed to set it up correctly.

By far the easiest, quickest and cheapest option is to sell your camera as a "spare or repairs" example and to use the funds towards another used example in good working order.

You have the added problem that when the lens did get stuck and you forced it free, you may have broken other internal lens parts. Even a professional repairer would not try to fix the lens assembly, they'd just order in a complete new lens assembly and fit that instead. The cost of the part alone, even without labour charges, will exceed the cost of buying another fully functional G5 privately.

Drop my Nikon D100 camera with a Tamron AF 75-300mm LD lens...lens will not extend, stuck on 200mm. If is worth repair, or can I repair it myself?

First question "is it worth repairing" if it were mine I'd look to see what a new one is worth then divide that in half (cause that's what you might be able to buy a used one for) then figure about $120.00 for cleaning lubricating and adjusting the your lens. With your lens you know what you have, buying used might need the service. you are the one to decide. As for the second question "can I repair it myself" short answer no. If you have to ask if you can repair it then you don't have the necessary tools and general knowledge of how to dismantle and reassemble the lens (and have it work when finished). The lens took a hit and most likely set the inner and outer lens barrels out of alignment causing the inner barrel to slip out of its seal and or focusing gear and hang things up forcing it will break parts causing more repair costs. All else fails get an estimate before repair. Been there with a lens myself and after a couple a months without bit the bullet and had it repaired. Cheers best of luck

Hi, It appears there is a small amount of fungus inside my lens, and when taking a picture, it comes back very dark. What would a possible remedy be for this? Many thanks Jon

This is actually a very common situation for older lenses. You should take the lens to a trained technician and have them clean the inner elements of the lens. Often times they can, if the fungus isn't too bad. In extreme situations, they will need to replace the element itself.

Putting it back together

In 1965 I did the same thing with a Nikon single focal length lens my F Photomic. This lens was far more simple then a modern AF zoom lens. I had to bite the bullet and pay a camera repair man to fix the lens. He told me that had I not tried to fix the lens myself, the repair would have cost 1/4. The only answer to your question is to take it to a camera repair man and get a quote. I would check the quote against the price of your lens on E-bay and use that to determine if you want to fix your lens or replace it.

By the way, it is very rare for dirt between elements to be so problematic that it results in a degradation of picture quality.
