EDIT 13 April: In retrospect these images could likely have been improved had a wider aperture been used. They were taken at f16 but at approx. life size ... thus equivalent aperture f' as per formula f'= f(m+1) is f32 … which is into diffraction territory and must be affecting image clarity.
Additionally, the 1" sensor's 2.7x crop factor may have an effect on DOF. To the best of my knowledge the DOF is increased by a factor of 2.7 … in the same way that e.g. on M4/3 format , an f1.2 lens only has the DOF equivalent to an f2.4 FF lens when used at full aperture (due to 2x crop factor). Thus wide aperture M4/3 lenses are not as suitable for differential focus full aperture imaging as regular FF wide aperture lenses. However, does this 'crop factor DOF adjustment ' hold true for high magnification images?
I need to return to the Swaddywell nature reserve and try and take similar insect photos with the Nikon 1 J5 using wider lens apertures. If foregoing theory is correct, should be possible to use e.g. set aperture f8 at approx life size magnification to give actual f16. However, with a 1" sensor's 2.7x crop factor, would this result in a DOF similar to that obtained at 2.7x 16 i.e. f43.2 on FF format?.
Comments most welcome.
Swaddywell nature reserve is an ancient disused limestone quarry where the terrain on the actual limestone cliff geological fault is very undulating. Rocks fall from the cliff and there are myriads of crevices which attract many types of insects. In sunny weather the rocks heat up offering warm perches - especially for butterflies.
I've no idea which actual species this is … any advice of both common and latin name would be much appreciated. Thank you.
