Re: auto focusing problem

On a Nikon D40, set the control knob on top to M for manual. The lens will work just fine. This is for a manual focus only. I use a D40 with a Phoenix 500/1000 mm manual focus with great results.

Re: auto focusing problem

The D40 is like all Canon EOS bodies.
Autofocus motor is in the lens, not in the camera.
You can look if it has a pin at around 5 O'Clock from the front of the camera body. Looks like a small screwdriver's tip.

Re: auto focusing problem

Technically it is compatible... just you have no autofocus. You can still use it as a manual focus but I can't imagine it being much fun over that sort of range. I'm getting a 70-300 macro af lens that is manual focus only for my d40, but for macro i prefer to manual focus.

In the end their definition of campatible was different to yours.

Re: auto focusing problem

Your camera is only compatable with AFS-type lenses because it has no screw-drive motor.  You can only use AFS Nikkors and Sigma HSM lenses (the lens actually has a motor inside).  You were misinformed.  Bring the lens back and ask for a refund. Take that money and purchase a compatable lens somewhere else.

I have a quantaray 70-300mm f4-5.6 lense for nikon mount mounted on a nikon D-40 and wish to use auto focus but cant seem to set it to it. Any help would be nice.

The D40 body can only autofocus if the lens is equipped with it's own in-built autofocus motor. If you have an AF lens which relies on the camera body having the AF drive motor then you have to use MF only. To cut cost and weight, the D40 relies on using lenses with their own AF motors.

Quantaray is a Ritz badge-engineered product, usually based on a Sigma/Tamron design but not always identical to those brands internally. As Ritz don't have a UK/European presence they're unfamiliar to me, but if it's the same as the one shown on this website, then it definitely lacks a drive motor, the second photo down when enlarged clearly shows the mechanically operated AF coupling at the six o'clock position. Again, to cut cost, the lens shown does not have a built in AF drive motor.

If so, your only fix is to either upgrade your body or lens to versions which aren't cut price models, or to simply focus the good old fashioned way, knowing that what you've focused on is what you want and not what the camera thinks you want... ;-)

I have just recived a quantaray 70-300mm f4-5.6 lense for nikon mount, and have mounted it on my Nikon d-40. I can take nice pictures using manual focus but, can not seem to turn it to auto focus. Any...

As far as I can tell, this lens does not have the focusing motor and thus will not autofocus on the D40.

The macro functions should work fine, though of course you'll have to focus manually.

Will the Quanta 28-200 for the Nikon n75 work on the Nikon D5000?

Yes and no. I assume the lens is of more or less the same vintage as the N75? If so, the lens will fit onto the D5000. All of the camera's exposure and metering modes will work properly. However the lens lacks an interal focus motor and thus will not autofocus on the D5000. You can focus manually, and the green focus indicator in the viewfinder will continue to work.

Nikon d40 wont autofocus

Your 28-90 AF-D lens can't autofocus with the D40, which requires AF-S lenses with a focus motor in the lens. Sigma lenses with "HSM" (HyperSonic Motor) in the name also have the focus motor.

Auto focusing problem

The D40 will only autofocus with the Nikkor AF-S lens...look for the AF-S in the lens title. For 3rd party lens, only SIGMA with the USM title will autofocus.

To use the will need to use the "Manual" mode of the camera.
