Originally posted by Gary G Excellent images, and the type of macro results I am looking for. Wondering if there is any noticeable difference between the DCR150 and DCR250. I think the 250 may reduce the DOF even more and is harder to focus, but that's just from what I've read. With a price difference of just a few bucks I am wondering which would be the better investment and easier to use, at least for an amateur shooter such as myself.
I guess I'll have to check out the Raynox thread. Just curious, were the bee images shot with the 150 or 250 lens?
Gary,
The DCR 250 close-up lens is almost twice as strong (125mm) as the DCR 150 (208mm). As a result, it is suited for shorter main lenses (magnifications above 1X are hard to handle). It has a shorter working distance because of its higher strength. (I've not heard of any difference in their optical quality.)
Also since the 150 is on a longer lens than the 250 would be, it is further from the flash, so the flash will be aimed better.
The above implies the Raynox DCR 150 is easier to use.

PS The optic relationships:
Magnification ~ Primary_Focal_length/Close-up_focal_length
Working distance ~ close-up lens focal length.
