I am using nikon D50 with nikkor macro 105mm to photo jewelry. Although i am using a tripod (a cheap one), somehow I can't get a clear focus of the object. It seems the camera shocks a very little bit when it takes the photo...I am already using a remote shutter to take the picture. Can someone help me with this, is it because of the tripod or what?

though you use a tripod, doesn't mean that you should apply a slow shutter speed, what was the speed then?

[rcfchong]

The F45, 1/8sec, manual focus...the result is out of focus for the whole picture. With the same focus but F8, 1/125sec, the picture is fine...but i need to use at least around F45 and manual focus

有冇用反光鏡預鎖?

1. Shoot it farther away from the object to get more depth of field so that you can set larger F stop eg. F16 and higher shutter speed.
Crop the image afterward.

2. Lock the mirror when you take the photo

F45 ? Which Nikon lens offer such a small aperture?

If you use F4.5 with a macro lens and at a very short distance, the depth of field will be too limited, a slight movement would cause the whole thing out of focus. Try a smaller aperture together with a robust tripod.

Save as raw if possible.

A ring flash may be a good idea.
