How can I find out the settings available on a Quantaray 70-300 mm zoom lens?


Quantaray has made several different 70-300mm lenses so I'm not sure exactly which one you have. However, if the lens doesn't have a AF/M switch it's no big deal. Assuming it's an autofocus lens, it's always on. If you want to switch to manual focus, flip the switch on the camera body.

If it's an older manual-focus Quantaray lens then the question is moot.

Is Quantaray NF AF work with Nikon D3000


Quantaray lenses are available with a variety of mounts. Assuming you get one with a Nikon mount, then yes, it will work with a Nikon camera. However, unless the lens has a focusing motor, it will not autofocus on the D3000. Some Quantaray lenses have such a motor, some do not.

One of the gears in my 70-300mm Quantaray lens is broken. Is it worth getting it fixed? Or can I sell it to someone else who may want parts? If so, how much would it cost to fix, or how much could I...


Fixing it could be at Least $ 75 to $100 and since the lens only sells for about $200 it may not be worth fixing. To sell it broken for parts will yeild you much less money. But if you can sell it and get enough money to keep it out of a landfill then it was worth it.

The Quantaray 70-300mm lens


Only if you get the version with the built-in autofocus motor. The D3000 lacks a mechanical AF coupling so AF lenses which need to be driven by a motor in the camera body will require manual focussing.

Either way, you're far better manually focussing the Quantaray/Tamron 70-300mm: the AF performance is very slow, very noisy and hunts around a lot to achieve focus.

Although the Quantaray and Tamron versions are identical lenses, if you have to buy this low-quality budget model then go for the Tamron: it's absolutely no better lens quality (and usually the same price), but the manufacturer's warranty from Tamron is much better than Ritz and is internationally valid. If you resell the lens then the Tamron will have some value (not much though) and the Quantaray will be near worthless as it's not so widely known, and has a poor reputation amongst those familiar with the brand.

"Cheap" isn't always the same as "good value"...

I purchased a Quantaray Autofocus Lens/Manualfocus lens 28-80mm F3.5-5.6 For Canon AF. Exactly what camera does it work on. I have a Canon Rebel XT 350D and it gives me Err 99 message....so I assume this...


Hard to say without more info.

Is the lens just bought new? If not, it likely is 'chipped' for the Canon AF film cameras. I do not recall if Quantaray rechips their lenses. I believe Sigma does theirs, but not sure about Q~. If you got the paperwork with the lens, contact a repair center or Quantaray.
Contact US1 Photo at 877-300-8070. they are a Quantaray dealer. Ask for the number to the distributor, warranty repair facility and for the number of the quantaray home office. One of them should help you get the right lens.

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 28-200mm Aspherical IF


Usually.
Quantary Lenses are made by either Sigma or Tamron That lens was usualy made buy sigma. the way to tell is to take it to a camera store that sells 28-200 lenses and hold your lens next to the sigma or tamron. They will look the same just with a different name. one of the main difference's between the store brand quantaray and sigma is that alot of time the metal bearings used in the name brand are replace with plastic ones for the quantaray. I tell you that just so you know why the sigma lenses cost more.

you can also find broken ones on online auction sites and use them for parts.


hope you get it working,
Caleb
