Peter Gaunt: Interesting looking camera. Why though does this site, and some others, persist in giving sensor sizes in rather bizarre fractions of an inch such as 1/1.7 (there's even mention of 1/1.63 somewhere in the article). It's so difficult to visualise. What's wrong with simply saying 15mm or 0.6".

Yet when I went to Nikon's site to check (couldn't find the info on Sony's) their '1' series the info is in mm. Not desperately important in the grand scheme of things. As G Davidson says, area would be best.

tr6me: Very interesting article, thanks! Another option is to work with a tilt belllows device for control of DOF and focussing plane. http://forum.mflenses.com/userpix/455_tiltshift_bellows_1.jpg

Focus stacking and setting up macro compositions takes time. The insects in the photographs above were they drugged, glued to a leaf or... dead...?

P.S. Working with a DX sensor DSLR (instead of FX) gives a slight increase of DOF. Using a 24MP DX sensor would be ideal for macro.

When I was a biology student 40 years ago we used to keep insects still long enough to identify them with cigarette smoke.
