Question about Quantaray 100-300mm F4.5-6.7 Zoom lens for Minolta

1 Answer

Autofocus is stuck on Quantaray 28-200mm F3.8-5.6

Hi ! I have a Canon RebelX S Camera with this lens. It has been barley used either and they had been sitting in a drawer for a couple oy years, (with Silica Gel to prevent fungus). When I tried to use it the Quantaray will not Autofocus. I tried the original Canon Zoom lens 35-80 the Autofocus works fine. The Quantaray lens in Manual focus works, and in Autofocus tries to move (you can hear the autofus motor) but barely does. After moving it manually, it has begun to move somewhat. Is there a way to lubricate or 'exercise' the lens without opening it up ?

Thanks !
Jorge

NEVER open it up. You will destroy the dust seals. Have Canon repair it.

I have been researching this problem and found there's nothing you can really do. Appararently, the quantaray, being an older lens, wasn't made to work with this latest era of cameras. Though it might work perfectly with your older camera, its technology is outdated as it relates to digital cameras1.gif and can't mesh with the latest and greatest. By the way, most of my questions were answered on the Digital Camera1.gif Resource page (www.dcresource.com

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

SOURCE: aperture stuck on quantaray 28-200mm for canon AF (rebel)

Does the lens have an aperture ring? If so, some such lenses also has a 'lock' (a tiny button near the narrowest aperture) enabling it to be used with cameras having CPU contacts. Check if your lens has this.

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.

Camera compatibility


Quantaray makes lenses with many different mounts. If the lens has a Canon EF mount then it will fit your camera. If it has another mount, Nikon for example, then it will not fit your camera.

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.

Can I use Quantaray AF 28-90mm f/3.5-5.6 in a NIKON D5100? Thanks.


Quantaray makes lenses with a variety of mounts for a variety of cameras. A lens with a Sony mount, for example, will not fit onto a Nikon camera. Assuming the lens has a Nikon mount, it will fit on the D5100. However, the D5100 requires the lens to have an autofocus motor. If the lens does not have such a motor then it will not autofocus. It will still work fine as a manual focus lens.

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.

Is the quantaray autofocus af70-300 lens compatible with the sony alpha 300


It depends on the mount on the camera.

Quantaray is a 3rd party lens maker. They make the lens itself, then add a mount for each brand of camera lens mount. In some cases, you can have the mount changed at a camera shop.

But the only way to answer your question is to know what camera it was used on previously. If it was used on a Sony, then, likely, yes.

Will a quantaray 28-105 1:3.8-5.4 Zoom lens Autofocus from a 35mm rebel ti fit on Canon EOS Digital Rebel 6.3 MP 300D?


The 35mm Rebel Ti and the Rebel 300D use the same lens mounting protocol. All Canon cameras designated 'EOS' use the autofocus EF lenses. If your Quantaray lens worked on the Rebel Ti, it will fit and should work on the Rebel 300D.

Quantaray 70-300 zoom lens


The lens is for Minolta/Sony A mount and you are trying to use it on a canon body which has the contacts and mounting points in a different position so it isn't going to work as well as a lens with the correct mount for the body you are using if at all you will need to get the lens mount changed or an adapter built to allow the lens contacts to mate up in the correct order
will be cheaper to buy a camera body to fit the lens or a lens that fits the canon mount lens
