p.1 #1Butterfly with MP-E & 2X TC
Not for comp or artistic impression , was standing on tippy toes just to reach him with face not touching cam.
Just trying to post what I can with this setup, so anyone interested can continue to evaluate for themselves the image quality and if they would like to pursue this as an optional piece of equipment for their bag of macro tricks. My experimenting will come to an end in the next couple of week s so I can get back to more serious things .
Best Tom
Will be on a short vacation in Florida this week and part of next but I will try to drop in .
1st shot at 1.5x
2nd at 2 some odd x
3rd at 3x
4th at 4x
800 ISO WHAT THA %^%$&
I hardly ever shoot this high , probably lost a little detail from that.

They look pretty good to me, Tom. Are you still shooting in Adobe RGB? I noticed from your last post that it appears you have the TC 'attached' to the MP-E somehow...you have a thread adapter?

Tom, if you handheld these you did a great job (and even if you didn't). I know this lens takes some practice to master.

kenny the TC is attached to the lens via a 58 mm male to 49 mm female step-down ring the a M42 rev ring.

John the subject was about 7 feet above my head on the brick of the house , I'm 6' 1" the MP-E with 2x and cam make up the rest of the distance Almost . I rest the front of the lens in my hand and it against the house and tried to keep the body off the brick , I was depending on the flash to help me , but it was all I could do to see through the eye piece. I was about 1" away from being able to put the cam against my face. The things we do for love .

Tom - these all look good - assume the iQ on the full size originals is ok ?

Brian the IQ didn't change much so I would say what you see is going to be what you get. It does seem to be a viable setup to expand the in field usefulness of the MPE.

Is it my mistake, or does the DOF seem too large for the magnification? I gather that Lord V was running to "excess" DOF too...not that anyone would complain, of course.

The quality looks quite nice, even at ISO800. It's an interesting little experiment.

Phil , I certainly thought that the DOF looked too deep for the aperture settings in my trials. Almost as if you were getting the apparent aperture from the MPE-65 magnification without the TC and the lower mag with the TC did not remove this. Unfortunately also seem to get the diffraction that goes with it. So complete guess is that you should use the aperture you normally would with the MPE at the mag setting you have on the barrel without the TC when using it with the TC if that makes sense. Luckily I think the light losses associated with the optics mean you have to use fairly wide apertures if shooting natural light.
