Well, I must have been too sloppy in my reply. Let me try to clarify. And I may have been wrong, of course
Originally posted by Blue You lost me with the comment about a 35mm ltd. [...] I disagree with you on the use of a microscope for magnification though for certain kinds of macro shots. Good scopes can go beyond macro and stack lenses, especially trinocular configurations.
The 35mm ltd. wasn't mentioned. But it does exist. In Europe, due to its nice pricing (339.- USD), it rules up to 1:1 magnification. On a K20D, it resolves 5µm and any experiments up to this resolution have been abandoned by most Pentaxians over here. This is what I tried to say.
Of course, Raynox equipment is nice if you haven't a DA 35 ltd. But I would always save the money to buy into the 35mm ltd. instead.
Originally posted by kristoffon That goes against my experience (18-250 zoom + 50mm reversed) - if I stop down the 50mm below f/2.8 (with the zoom at 250mm) the image circle no longer fills the screen. If I leave it closed at f/22 (min, aperture I think) all I see is a small dot of light in the middle of the viewfinder.
This is strange and shouldn't happen. It didn't happen in my case (300mm + 50mm). It also cannot happen taking the laws of optics into account. Because, between the two lenses, you have parallel rays of light coming from the focus plane of the 50mm. You must have had an imperfection in your optical setup. Like focussing the zoom to something other than infinity. Or I am wrong and only had good luck.
Originally posted by Igilligan I am confused, are you saying that the raynox lens are useless compared to the da 35 ltd? Or that they are useless on the DA 35 ltd...
What I said above. But your macro images are superb images. Congratulations. Esp. the capture of details in the bee's eye is an achievement. But, as I said, a DA 35 ltd. could have done it as well, "out of the box".
You may catch a little bit about the enthusiasm in this 1286 posts thread here:
DigitalFotoNetz.de :: Thema anzeigen - smc DA 35/2.8 Macro Limited
Which is why I took it for granted that our thread here is about "larger than 1:1 macro" photography
EDIT:
Wait a second... your first image is a fly, not a bee, right? I ask because fly eye ommatidia are larger than bee eye ommatidia.
