Old G5 technology, F22, and ISO 800...wow, I love them!
Bruce
Thanks.
I use f/22 because I like to get as much depth of field as I can for invertebrates, for which I pretty much always use f/22 on micro four thirds. I'm happy to trade off the loss of sharpness/detail from diffraction against the increase in depth of field and do what I can to mitigate the image quality issues with post processing and keeping the output size down to 1400 pixels high.
I use ISO 800 when using flash for invertebrates on micro four thirds so as to keep flash recycling time down. In fact ISO 800 is pretty much my "base ISO" with micro four thirds as I use it most of the time for my other favourite subjects, flowers, buds, seed pods etc (but I use ISO 800 for different reasons - I use natural light for botanical subjects). Actually, I use ISO 800 for the one thing I use APS-C for these days, common birds in flight; that is in order to keep the shutter speed fast enough for the apertures I want to use.
As to the old technology, I find that when using minimum aperture I can get very similar looking results (given raw originals and my current post processing) with almost all of my cameras/lenses, including for example a 10 mpix, ten year old Canon SX10 bridge camera (actually, from JPEG originals in that case). In fact I generally use a bridge camera for medium sized invertebrates like these, for which I shoot f/8 (minimum aperture) and ISO 100 with my bridge cameras, which gives much the same noise, depth of field and (lack of) sharpness/detail as f/22 with ISO 800 on micro four thirds.
I have been photographing these wasps over the course of several days and the first session was with my go to setup for this sort of subject, an FZ330 with Raynox 150 and KX800 twin flash. I think on balance I prefer the FZ330 images, although that is mainly because I happened to catch some poses and combinations that I quite liked, for example the following three (there are another 13 images from that session in
this post in the Macro forum).
