I won a very cheap set of M42 extension tubes off ebay and tried the largest
tube yesterday using the above lens. This is a handheld shot, and just
slightly off from looking finely focused. My problem is, if you use a tripod
or other supportive device, the plant/flower still moves, infinitesimally,
even on a windless day. I guess having the camera rigidly placed reduces
the problem of focus at least by half:

If you shoot flowers live on plants, they will shake of course, so your only choice is to use fast enough shutter times. For a gentle breeze 1/250 should be enough in most cases.

Nice shot Bill!
1/30s for macro 1:1 is too long

Poilu, you beat me to it! Yes, I checked EXIF and 1/30 is way too long. I
will try shutter priority and see what happens. Thanks.
Thanks, Orio!

OK, it's official, I'm an idiot! I tried Shutter Priority and set it to 1/200 since
there was hardly any breeze and of 7 shots taken, 5 I could not tell which
was better focused. Before, I would get 1-2 out of 10 shots that might be
keepers. The light is midday, not good, but I am definitely encouraged, and
this is handheld, too:
I'm seeing more detail than I did before, the fine hairs on the buds, stems.
I will wait for better light today for the peaflower.

Smart sister!  I've thought of using plexiglass, same idea, but then,
where's the challenge?  |

Attila, just look at the second one, I hope to do a better version on the
first. I hired the ant to pose by the flower for scale, wonder where he
wandered off. |

The second shot is much better Bill, beautiful, but did you really use shutter-priority mode with the Helios? I didn't realise the camera can work round not being able to set the aperture.

Peter, I set the shutter speed at a constant 1/200 or whatever I want and then adjust (by trial and error) for correct aperture. Yes, the improvement
in focus is demonstrable, silly me. |

Attila, I rather like it, too, but got a comment on another forum about
"camera shake" which is photography-speak for focus issues. |

Andy, they seem to like raw sugar and honey! LOL Yeah, the daisies are

Luis, when it comes to National Geographic, I have nothing to worry about!
But have loved the pictures in that pub since the 50's. |

You guys are having all the fun now that I am back to work all day! I actually could have been involved in this thread. I knew a faster shutter speed was needed in the first shot, as I have experimented with extension tubes in the past. I also like the second shot Bill!

It's not just an issue with the extension tube Bill - the rules hold good for any macro focusing - specialist lens, tube, bellows, reversed lens whatever. What you are seeking ideally is smallest aperture (depth of field) and fastest speed (absence of blurring). Part of the equation is to use a tripod (recommended) to reduce the speed requirement a bit and give more room for the aperture. The first picture has an "atmosphere" to it, which I think is what some find appealing. The second is "cleaner". Personally I like both but prefer the second.

Mike, thanks for your comments, hope work didn't beat you up!
Patrick, I know, tripod is going to have to be included if I want anything
worthwhile. The problem with Shutter Priority is when you start to lose the
light your DOF gets narrower and narrower to compensate, otherwise it
looks like a dark mess and when you try to beam it up in PS you get this
lovely noise:
Shot today towards dusk, capping off a frustrating afternoon...
I still need to upload a custom profile for the Oly e300, but to expect
Noise Ninja to be the silver bullet may be going too far.
Thanks for insights and comments, Patrick.
