Sigma 70-300mm DL Macro Super Lens compatibility for Nikon D40X DSLR Camera

Yes.

Yes. Bear in mind that many Canon digital SLRs have a sensor smaller than a frame of 35mm film. This results in the image being cropped, narrowing the field of view and making the lens behave as if it was of a longer focal length.

before buying ask the sigma salesman or dealer about it, i know only for nikon camera- it's lenses are compatible for all camera, digital or film base slr cameras.

This lens can work with 5D mark II ?

Hi,

The original DL lens was designed for non-digital application and Sigma released the DG version that was optimized for digital bodies. That said, the lens should still function to a certain extent on both and function normally on your wet film SLR.

My first suggestion would be to check the contacts on the lens and camera. Give them a good clean with a pencil eraser being careful that nothing goes inside the camera body whilst doing it.

If this fails to make any difference than the next thing would be to try the lens on a different body. The fact that the lens isn't performing correctly on two bodies leads me to think it is a lens problem but it's good to eliminate the bodies.

If this fails to make any difference then the last thing is to get it professionally looked at. Most local camera shops would do this for you. Be wary though that repair may cost more than the lens and it might be the right time to upgrade to a nice new lens to get the most out of that new DSLR!

Hope this helps, if it does please rate my help.

Thanks

All after market lenses are specifically designed for a brand of camera. They are for Nikon, Cannon, Minolta etc.. They can not be cross branded just as you could not use a Nikon made lens on a Pentax.

Yes, if you get one with a Canon mount. Sigma makes their lenses available with a variety of mounts; a lens with a Nikon mount, for example, will not fit on a Canon camera.

It could Canon, this is one of the edge Canon over other brands. Its versatility on lens mount is better.
