My sigma 50-500 lens is lock in 500mm position


I believe on some Sigma lenses there is a switch to lock it in a 'Macro' position, usually at the long end of the zoom range. If this applies to your lens, it may be worth checking that this has not been accidentally set. There may also be some information in the manual whichcame with the lens.

Sigma 17-50 2.8 EX HSM lens is stuck and won't zoom. It takes pictures Ok and sometimes it even focuses in automatic. I can also take pictures without zooming. Can someone help on how to fix.


Hi.
Probably the problem come from a loose screw inside zoom cylinder. Normally it happens due to constant use or vibration.
The GMR sensor is very sensitive to magnetized tools an needs an accurate position to function properly.
If you don´t have experiencie with this electronic systems, it is better you to contact Sigma Service in Ronkonkoma, N.Y.

Lens for Nikon D60


I will try to help you, but please understand that my experience is with Nikon film cameras. Assuming that the D60 works in a manner similar to a Nikon 35 mm body and that Sigma macro lens work like Nikon macro lens, you should be able to determine the usable subject to lens distance by experimentation. First, make sure the lens is in the macro mode. To do this you must set the auto-focus mode control to the manual focus mode (see your manual). On Nikon lenses, you must first set the focus ring to infinity, then move slider switch, which has two positions marked; "normal" and "macro., to the macro position. You should now be able to rotate the focus ring to the macro range. Use the zoom ring to zoom in and out and focus with the focus ring. The the range over which the lens to subject to lens distance will yield an in focus image will be rather limited and in the range of an inch or so to 6 or 8 inches.

Trouble focusing with sigma 70-300 DL macro super lens


It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.
