I have a Nikon D60 camera. I have two lens for it. My brother purchased for me close-up lens kits with 3 lenses in the boxes. 1x, 2x and 4x. He got 2 sets for me, one for my Nikon 18-55mm lens and one for the Sigma 70-300mm lens. I have no trouble with the 52mm Nikon lenses but I'm having serious trouble with the Sigma 58mm lenses.

When I take a pic with the Sigma, everything is perfect. When I put one of the close-up lenses on the end, I can't get the camera to focus. It doesn't matter which one I use, the 1x or the 4x. It also doesn't matter if I am focusing far away or closer in, it still won't for focus. The camera wants to, it just can't.

Help?

The distortion caused by the filter type close up lenses can cause difficulties with the Auto focus system.
Try single area AF and see if this helps with the issue. You can always use manual focus if need be.

Unfortunately, I've tried the manual focus, too. I should have said. I was thinking I was too close to things but I've tried it on our mountains. Still no go.

Could it be a problem with the lenses? Or am I just a doofus? I've tried manual focus with the Sigma on the macro setting and without.

Are you saying that manual focus didn't work for close-up shots?

Well then it might be that the lens is not compatible with close-up filters due to the arrangements of the optical elements. Mind you the lens is already a macro lens with an up to 1:2 Magnification factor so close up filters are IMHO not needed and would just unnecessarily distort the picture.

Okay. I'll let my DB know and we'll maybe send them back. I love the other with the Nikon, though. That's a keeper.

W/O close-up.

Okay, I figured it out. And the answer is...I'm a doofus. LOL

I wasn't getting close enough. Duh.

Thanks for the help, though. It pointed me in the right direction.
