Spider. 3 points of view.

I am practicing macro, using Nikkor 105mm macro lens with macro extension tubes. C&C please.

Great job on detail... I like the composition of the first one with the spider on the lower right!

Thanks for looking and your compliments.

The sharpest of your three is image #2.
Exif image #2:
Camera Model: Nikon D700 (12.1 Mp Full Frame Sensor = good cropping resolution)
Lens: 105.0 mm f/2.8
Image Date: 2015-07-14
Focal Length: 105mm
Aperture: /22.0
Exposure Time: 0.0080 s (1/125-sec)
ISO equiv: 400
Exposure Bias: none
Metering Mode: Matrix
Exposure: Manual
Exposure Mode: Manual
White Balance: Auto
Flash Fired: Yes
Based on this image, my recommendations for similar future situations:
1.) Drop ISO to 200 (- 1-stop to reduce noise);
2.) Increase aperture to f/16 (+ 1-stop to reduce Small Aperture Diffusion);
3.) Reduce shutter duration to 1/200-sec (NO difference in exposure, but can reduce some ambient light movement).
Image #3 was captured at f/29, which has contributed to loss of IQ.

Thank you very much for your C&C and recomendation. I will follow them.

I'd recommend opening up the aperture to around f/16...but this is a nice shot of an orb weaver.

The difference in the front to back DOF on a 105 on a fullframe DLSR at minimum working distance between f/22 and f/16 is something like .02-inch which is equal to 0.508-mm. These are estimates calculated w/o factoring in extension tubes, so I feel it is safe to say it would not be greater than that. Given that so little DOF is gained and with the loss of sharpness due to small aperture diffraction, f/16 is a reasonable compromise.
