The problem I often have with photographing wild flowers is that to use an aperture small enough to provide sufficient DoF the shutter speed is so low that the slightest breeze will give you a soft image. I'm guessing that one could use a larger aperture for a faster shutter speed then stack the results. I say guessing because I haven't tried it, yet. The alternative would be to buy a K5...

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

How would a K5 help Chris ??
K-7 | K10 | DA 18-135 | DA 18-250 | DA 55-300 | DFA 100 |

I'd think - K5 can use higher ISO therefore faster shutter speed
... just another middle-aged guy with a hobby. I have an extreme macro learning site at extreme-macro.co.uk - Pentax-centric, your feedback and comments would be appreciated!

It wasn't an entirely serious suggestion. I was alluding to the much better IQ at higher ISOs than I get from my K20D. I almost never use the K20D over 400, and prefer to keep it to 200 if at all possible.

Actually, if I really wanted excellent IQ and consistent focus as in the example image I would use my Horseman and utilise camera movements/Scheimpflug to achieve that in one shot.

Of course the wind still causes a problem with any multiple shot combining technique, the leaves and flowers end up in different places!

I've been advised by a few people now that small apertures are prone to defraction problems and can be more blurred than those shot at wider ones.
