I have a 5D III and EF100 f2.8L Macro IS lens. I find (as most people probably do) that autofocus becomes less accurate the closer I get to minimum focus distance. Does DPAF give more accurate results than normal AF at close distances?
Mt Spokane Photography said:Do DPAF at about 50X the focal length. Its not going to help doing it at mfd or close to that. Use contrast detect in live view for AF if you really want to try AF near 1:1.
If handheld, set the manual focus to focus as best you can then move the camera back or forward a tiny amount to get best focus. I've done it handheld, but I've also braced myself as best I could, and its still difficult.
If on a tripod, contrast detect may work.

Can be done hand-held with practice. Focusing rail is another option, though slower. I recently got a Hejnar 5-series and quite happy with it, particularly the lack of slack and lateral movement when reversing direction.

Sorry, focusing screens aren't available for the Mark 3. Oh and camera shake from handheld will always show on that tight of a shot, rails are amazing.

focusingscreen.com makes matt focusing screens for the 5D3. Not too difficult to switch out, did it on my 5DsR.
Re handheld, no problem with flash. or keep exposure time well shorter than 1/200s and it is fine with a bit of practice. As always, not every shot will work, but shoot enough, and you'll have some keepers.
Rails are good for some applications, but not all. Good luck shooting jumping spiders with a rail. I have several, including the motorized StackShot, but sometimes I shoot hand held with 100 MP / 180L / MPE 65 macros.

I agree about spiders, I guess since I don't shoot moving macro, yeah you got me but the 5D3 and the screen? that's not 'average' user serviceable. Is the S/R line the same? And you did the surgery yourself? Then I am impressed.
