Question about Quantaray 100-300mm F4.5-6.7 Zoom Lens for Canon AF

POSSIBLE MOLD INSIDE CAMERA LENS

I have two Quantaray (Minolta) AF Electronic Telephoto Lens showing internal spider web like indications of, I presume, mold.

Is this an economically repairable problem or should I just "junk" them....?

Thanks

It is lens fungus and you're correct in your assumption that it's uneconomical to professionally repair on your lenses. But it need to be pretty bad before it affects image quality so don't junk them just yet.

Some types of lens fungus can be killed simply by leaving the lens out in sunlight, but I'd suggest that it's better to leave them exposed to the indirect sunlight on a bright overcast day to prevent any chance of sharply focussed light burning the inside of the lens. Killing the fungus won't remove the dead stuff but it prevents the problem getting worse.

The lens has spider webs inside


Sounds like fungus/mold. Send it in to Canon or reputable repair shop. It will only get worse.

The lens is a manual focus lens. It doesn't matter which mode you have the camera in, you'll still have to focus it yourself.

I recently obtained a used Quantaray for Nikon 500mm f8 f/8 Mirror lens. I have a Nikon d3000 and I am not sure how to attach it to my camera.


For Nikon AF and manual focus SLRs. The compatible T Mount System makes it possible to use most any single lens reflex camera in combination with various front camera attachments such as telescopes, mirror lenses and slide duplicators. The T Mount is a metal connector that screws onto the compatible front attachment and allows this combination to be coupled to the SLR camera lens mount.

Quantaray 70 - 300mm for Minolta AF (25-166-4546)


Check you manual, but it should be no problem- Sony bought Konica Minolta to have the Minolta lens mount (and engineers). Your old lens doesn't have all the internal electronics (and connections) of the new lenses, but every old minolta AF lens i've tried works fine with alpha

Cameras compatible with Quantaray AF 70-300mm lens


Depending on how new your Minolta SLR film camera was, the lens may or may not work on a Minolta Digital SLR. In many cases, a lens with the correct mount (in this case, a Minolta mount) can be used on the same brand of camera in the digital format.

One thing you should know is that DSLR sensors are, generally speaking, smaller than the size of a 35mm film negative. Long story short, that means that your lens will have a magnification factor on the DSLR. Usually, it is in the range of 150%, so a 70-300 lens from a film camera would cover 105 to 450 on a Digital SLR.

To be sure about the mount, you'll need to seek advice specific to Minoltas -- probably best to take your lens to a local camera shop and see for sure if it fits and what features will work (aperature, auto-focus, etc) and which won't work on the DSLR.

Used on a Minolta Maxxum 800 si


Hello
The Minolta AF lens will fit and work on most of the Minolta AF bodies (it will depend on exactly what lens it is as to the compatibility), you will also find that it will fit and work with the new range of Sony
digital SLR camera bodies.

The Quantaray lenses are a little bit more difficult as Quantaray make lenses for several different types of camera body, it should mention on the lens what make the lens mount is for. If you post further information about the lenses it might help.

QUANTARAY FOR MINOLTA AF 70-300MM compatibility


Usually mounts are unique to a camera manufacturer. There are exceptions. Sony has the Alpha; lenses for the Konica-Minolta are the same mount. Your AF (autofocus) lens will work on it. You might also consider picking up a Konica Minolta 5D or 7D.....they're no longer made and hence are cheaply had.

The MD and Rokkor lenses won't work on the Sony Alpha.
THIS IS A CHEAP LENS (<$50 VALUE) SO I WOULDN'T LET IT DRIVE YOUR DECISIONS!!
