20 Most Recent Quantaray AF 70-300mm f/4.0-5.6 High Speed Auto Focus Zoom for Minolta Questions & Answers

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

Sorry to say but the lens needs to be sent in for repair. To repair or replace the AF motor is usually around the $200.00 range. Do not try to fix it yourself.

If it is just a case and cap go to Ebay to save money

What do you mean, loading disk... you mean card?

Either your viewfinder needs to be cleaned or your camera needs to be cleaned. Most of the time it is the mirror in the camera that is causing this issue and cleaning it will make everything better.

Quantaray makes their lenses with a variety of mounts. A lens with a Minolta mount will not fit onto a Canon camera. A lens with a Canon mount will work just fine on a Canon camera.

David - The lowest setting is the highest number; f22 is lower than f4. It's little counter-intuitive, but the lowest setting means the least amount of light - or the smallest aperture opening - not the numerical "f" value of the opening. Simply twist the aperture ring until the highest value "f" number is selected. Many lenses have a small tab or latch to lock them in this position - if yours does, you can use it to prevent this from happening again. You would use a command dial on most camera bodies to electronically change the aperture opening.Good luck!

Quantaray makes their lenses with a variety of camera mounts. A lens with a Nikon mount, for example, will not work on a Canon body. As long as you get the lens with a Canon mount, it will work with the 5D MKII.

Only if the lens mount is for the Olympus

Quantary makes lenses for a variety of cameras. A lens for a Minolta, for example, will not fit onto a Canon. Assuming you get the lens with a Canon EF mount, then yes, it is compatible with a Canon digital SLR.

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.

Yes, assuming we're discussing SLR cameras. It can also be used with most Nikon film SLRs.

Having gone over a month with no response, I assume cleaning the contacts solved the problem.

It depends on the mount. Quantaray lenses are available for a wide variety of mounts. If you specifically buy the one with the Nikon mount, then it will work. If you buy one with, say a Canon mount, then it won't fit.

The D40 does not have a focus motor, instead relying on a motor in the lens. This lens does not have such a focus motor, and thus will not autofocus with the D40.

its not junk, prob too expensive to fix. but makes a nice fixed focus lens. Quantray were on the same level as vivitar, sigma. So they are now that expensive to replace

Look at the writing on the lens. There is a number next to a circle with a line through it. The 70-300 is probably made by Tamron and sold under the Quantaray name. Probably a 62mm diameter.

Error 99 is one irritant in many Canon SLRs. In general, it means there is some problem with the contacts. So try cleaning the electrical contacts of the body and lens with a pencil eraser.Please take care to hold the camera upside down while doing this so that the residue does not fall inside. Also take out the battery and clean the contacts. Now re-attach everything and try taking the image. Also check if your lens has an aperture ring and aperture lock. If so, lock the aperture ring at the minimum aperture. If these do not solve the problem, try updating the firmware to the latest one.

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.
