I had to take some photos for work today and I don't do a lot of macro, in fact I don't do any macro. The problem I've got is the lack of DOF. I had to take some shot of damaged control boards for a report and here's one of the shots.
I used the 18-70 kit lens at 70mm with 3 close up filters (+1,+2 & +4) so that I could fill the frame as I didn't want to highlight the detail through cropping if I could help it. This shot is ISO100, 1/125 and F36! Despite having such a small aperture the DOF is terrible. The focus should be on the corroded pins not the writing but I believe my camera has a back focus issue anyway and that won't affect the DOF.
How can I get enough DOF to get all the pins on focus in this instance? I did try the close up filters on my 100-300mm but that was nigh on impossible to focus with and I'm unsure whether the extra focusing distance to give DOF would be negated by the extra zoom necessary to fill the frame in the same way.
Heeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelp!
Cheers all,
Kev
