I'm thinking about getting a raynox 250 to use with my tamron 70-300. How far away does it let you be for those macros?

The pics have tremendous resolution--I thought it was the K20. How much does this Raynox attachment cost?
About $60.00.

still not happening for me, I dunno why, maybe they are just too big for the speed of my net...
The cicada macros are the first two in this set. The shot of the full insect is not actually the same one as I posted in this thread. The first one in the thread was the Tamron alone. The one in the Raynox gallery is the Tamron + Raynox at 70mm focal length. It's pretty close to the same size as the Tamron's 1:2.

Thanks

I don't think I can post in the gallery. When I try to load photos in the forums, it tells me my quota is used up. The cicada macros are the first two in this gallery. Picasa Web Albums - Dan - Raynox 250

Very nice! Do you know what are those orangey-red spheres (triangle of them) between the insect's eyes?
AFAIK those are more eyes.

Those are called ocelli (ocellus singular) or simple eyes. Insects can have 0, 2, or 3 depending on the species. They are basically used for detecting light and perhaps motion whereas the compound eyes are for vision.

Thanks Blue. Should I have used red-eye correction?

What we really need now is software that does "Red-ocellus correction"...

Wow. You just came up with a project for my next graduate student.

Actually, while the lens is clear, there is a pigment associated with the photoreceptive membranes that can impart color to the ocelli of some insects. I think cicadas have rather diverse pigmentation.

The three little eyes were that dark orange colour in real life, not just in the photo.

That's really quite impressive and says a lot for both the lens and the adapter. How big a front element can these things fit on?

67mm is the largest. I was looking to use it on my Tamron 180mm f2.8 but it has a 77mm thread.
