Nikon MF 105 Micro-Nikkor + 50 mm stacked

Post by NikonUser »

Caught this spider in the house this morning:
Eastern Parson Spider Herphyllus ecclesiasticus; body length 8 mm
Overwinter as adults, often in houses; "fast runner and difficult to catch"
Photographed under a glass-topped container, partial stacks with Zerene. Live spider that would tolerate only a limited number of flashes.

Top: Nikon 105mm MF Micro-Nikkor, reversed, maximum lens extension + bellows to give mag. x1 on Nikon D810 (full frame); lens set at f/5.6

2nd: at full lens extension and full bellows magnification was 2x but extreme tips of legs outside the frame

3rd: 105 lens not reversed + reversed Canon 50 mm 1.8 set at Infinity. Nikon lens at infinity and no bellows extension (however even when closed and mounted on camera there is a 75 mm extension)
Thus, with a reversed 50 mm lens on the 105 the minimum magnification on sensor is 3.6x

bottom: actual pixels from 3rd image.

I am very happy with the quality of the stacked lens setup.

Just a query? fourth photo left leg, is that a little mite just before the middle.

Very glad that this was in your house, and not ours.

Very nice stacked result. Was the Canon lens wide open? If so, that is really good!

Certainly looks like it has legs, but if you look at image 3 you can see similar 'structures' on both the right and left legs in the same positions; also the pedipalps seem to have them.
My guess is they are not mites, maybe some sensory structures

Wow!

Which Canon 50mm 1.8? I am not very familiar with the Canon line but I know there have been several different mounts over time, and perhaps several versions of this lens.

Lou: it is an old lens; came with a Canon FTQL (?) from the late 1960's. Left over from my 1st 'real' camera.

Canon Lens FL 1:1.8. Range to f/16. Small front diam , about 48mm.

I had to join together a 52 mm male ring to a 48 mm (?) male ring. The 52 screws into the Nikon, the other into the Canon

Beautiful! I am very fond of parson spiders.
I can clearly see several plumose hairs, scattered about on the 4th picture. Some of the pedipalp, and more on the leg in the frame. Did not know that spiders had that.

I was surprsied to see this spider here in February. It has been cold with lots of snow.

Checked my spider manual; 1st edition:

https://www.amazon.com/Spiders-North-Am ... th+america

and it seems spider hair may be "erect or recumbent; simple, serrate, feathery to plumose, or clavate to broad scales"
