My highest mag. shot yet

[yeatzee]

Well Tonight/this morning (3:43 AM here) I took my highest magnification "legitimate" shot yet :)It involved a fully extended pentax auto bellows II, several extension tubes, and a reversed Pentax F 28mm @ F/4

The shot is a relatively small stack of 31 images, and is not very sharp. At this magnification i am greatly limited by the optics I have at hand so the image is no where near as sharp as I'd like it to be. It appears some microscope objectives will fit my needs perfectly

I was not planning on using this image as it was taken to test some lighting setups I have constructed but like the title says its kind of a milestone for me as a macro shooter.

its a boatman fly, the same species as this one I shot a couple months back:

Different coloring in the eyes which I found interesting

(please excuse the crappy background/bokeh. I can't find anything suitable to use thats not purple/orange which im sick of using. Like I said, I was not planning on using the image.)

4x5" paint sample cards from walmart make good backgrounds

Nice work.

It involved a fully extended pentax auto bellows II, several extension tubes.

It would be more informative to also state the total extension, in mm, not necessarily too precisely.

The bellows goes to 170mm, #2 and #3 extension tubes used, and a teleconverter DIY adapter about the size of the #2 tube if I remember correctly. I tore down the setup after writing the post and than promptly fell asleep hahahahaha

Images look good!

Regarding magnification, it's a good habit to snap one shot of a millimeter scale using the same setup just before you tear it down. It's quick, easy, avoids awkward and unreliable computations, and answers almost all questions about size and scale.

I'm thinking of reversing the Pentax FA* 24/2

In that case, you might photograph some lens mounting threads and write down which lens. M42 Pentax thread is particularly simple to work with because it's just 1 mm per turn. But buying a cheap ruler is probably more convenient in the long run...

Let me know how it works! I've been wanting to try reversing my Pentax K 50mm F/1.2 but 1. its to heavy to be practical (as I assume the FA* will be aswell) 2. the filter threads a little damaged.


@ RJlittlefield - yea im just gunna pick one up

[Guido]

This was done wit the FA 24/2 on the F 100 macro.
The 100 macro wide open and the 24 on F4.

About 4x, not the best stack but I gues the lenscombination does the job.

But as you said but 590 gr + 450 gr, more then 1 kg without body.
