Default Next housefly 'eye' close up

Hi,

i've always been trying to get closer, and I think I've found my current limit.
somewhere around ... 25:1 macro
(I know its larger than 20 and smaller than 30 so ?)

the lens used is an "American Optical Microscope Objective Plan Achro X10"



placed on a "RMS Thread to M42 Adapter for microscope objective cone"


on a pentax bellows (fully extended) with a k5, taking 41pictures and stacking them.


no cropping

It still isn't perfect
  • a lot of chromatic aberation - don't know if its the cheap lens or if all microscope lenses have this
  • not enough images - the microsled (read old cd-rom) still isn't fine enough
    a stepper motor would fix this, but I don't want to go that way (yet)
  • not sharp or enough details , again the lens or me
  • still need to find a better way to get the object in the viewfinder


Cheers

Ronny

Hi Ronny,

That's just sick (in the good sense!). I like that you're pushing your photography to the limits.

I'm still waiting to see the Lego/ CD micro setup!

It appears that you're having some great fun with fun with this. . .

A suggestion for locating the subject -- make a small disc with a hole in the center and draw fine lines radiating from the center. Position your subject in the hole, and the direction of the lines should point you towards your subject.

Good work!
Be carefull, it's a real cheap present, 1 fly (a dead one) , 1 broken cd player, 1 10x microscope lens (10€), and the adapter going for 40€, only the bellows are a bit more expensive.

Thanks Tachi

Superb stuff Ronny ..... you've now re-kindled my passion to look again at an original Pentax Microscope Adapter K that's for sale here and then see what I can marry it to !

Amazing detail - what a clever arrangement! Wonder how it would work with a higher quality objective. (Will have to look over my old microscopes...)

Wow! Didn't know you could use a microscope objective with a camera like that. That's amazing though I can imagine how much work it must be and how thin the dof is before you start merging things. I love looking at these things, but not sure I have the patience to pull something like that off.

Roni, I have also experimented with supper macro. My set up uses my 105mm 2.8 Viv series 1 macro with a 52mm to 37mm reducing ring and a Viewmaster projector lens (Wollensak f/3.0 anasstigmat lens ) hot glued to it. I think I can get a better quality projector lens on e-bay for about $10.00. I just haven’t gotten around to doing any more work with this yet.
I do not know what magnification I get with this combo but it is not that high that it cannot be used on a live subject like a jumping spider.



The sample pictures are my first experiment with macros of a wristwatch movement. The first is the watch with a 35mm lens so it gives you a pretty good size idea of what the watch looks like without macro.
The second two are with the super macro lens set up.These are single images not stacked.









Lighting of the super macros is with my homemade macro flash reflector and the pop up camera flash providing the even light. The led reading lights are not turned on to take the pictures. All the light comes from the on-board flash, the light diffuser and the two reflector paddles whose placement can be adjusted to put the light where it is needed to eliminate shadows. The flexible stem of the reading lights allows me to change the placement of the paddles as needed. I can use F16 to f22 and have plenty of light at ISO 200 to 400 with shutter speeds in the 250/sec range.
