Default D7i Macro modes

Anyone have a 'rule of thumb' for distances to subject where the close and far macro's focus? Best way to focus on a single component on a circuit board? I had 'focus but the photo was blurred even on the LCD screen. (How come?) Still trial and error but gaining, I hope!

Any example?

Is anything in focus @ all? if not it's more likely due to camera shake than focusing... Try a tripod!

You're @ extremely high magnification with very shallow depht of field. If it's blurred it's more likely due to amplified movement. If it's bad focus at least something in the picture should be in focus (ie the wrong thing!). The shutter speed is probably too slow (ie not enough lighting) did you take the picture with the flash on?

Are you sure you had the right thing in focus? There is very thin DOF at macro. Use flex point focus to select the specific thing you want in focus then see what you get.

why not use manual focus and tripod. also, magnify function will help focus.

How about adding a closeup lens? I often use a Cokin +3 ( I had from my SLR)

Default Close up Lens

Great replies, all. K-can reminded me I've got some closeup lenses from my Yashica to try for starters. Trying for decent depth of field at closeup about 4 inches. I'll post photo tomorrow to show what I mean.

Default Shutter speed?

NHL, 800 is too grainy, I've read. I've been trying 400. When in a hurry, tho I go to "P" mode which may be a compromise? Maybe I should setup some custom settings and save them to memory so they can be called up when the camera comes on.

cald,

four inches is way too close for the macro mode. check the specs in the manual. close up lens is your best bet.

cald- is this close enough-SMDs

mm scale

i think i should have cleaned the dust off of it.

shot this at highest jpeg res w/tripod of course
then pulled it up in PS7
cropped it just right and you have your macro image
