Two hymenoptera I've collected recently and shot in a fresh state, its a real treat to image them as they appear when alive, instead of the old dried collection specimens.
Chrysis impressa Schenck, 1856 - female
Probably the most common Chrysis species in Sweden, and as is the case with many chrysidids they are even more colourful when not dried as in collections.

Odynerus melanocephalus (Gmelin, 1790), first time I've come across this species considered to be NT (near threatened) in Sweden. Found at a typical habitat for the species, a brownfield site, this one underneath the Öresunds-bridge that connects Sweden to Denmark. It is not the host of C. impressa but of C. viridula Linnaeus, 1761. The colours look a bit washed out, especially compared to the rainbow party that's the Chrysis above, but it's actually true to life. The yellow colouration varies in this species, some are bright saturated yellow and others, like this individual, have a much more light yellow / bone-white tone.

Also using the Lomo 3,7 didnt check the actual magnification, but something like 4-5 times I'd think.

Thanks!
Yes, I'm very happy with how far its possible to push the little Lomo, both up and down in magnification.

Hard to say as I used a black background for these sets, but there appears to not be any darkening of the corners. When I pushed up the histogram to view the background there's no vignetting, as the background isnt 0/0/0 black it would have shown up I'd think.
(this is not one of the images used in the stack above, the images used for that one had the animal much more centred)

Did a real test;
at 2.3x mag (which is around 100 mm from the sensor to the Lomo's shoulder)
images taken from a single, totally unprocessed image that shows the vignetting and the difference in sharpness between the corner and centre. Saved as quality 12 jpg's, so they should be close to the original.
Left image shows the lower left corner (green square), the right is somewhat central (red square)
I set the corner to be as sharp as possible and then chose an area close to the centre that was in focus as well. Oh and the printed paper slip is not flat at all, so I cant say anything about the image flatness, but that doesnt really matter for stacking anyway

Very nice pictures - and thanks for the extra information about the insects and the Lomo.
