I may be interested... I don't know if you're in the market for any lenses or accessories for Canon cameras, but I'm currently downsizing my collection to subsidize macro and micro equipment.
I might also be willing to pay the full price, but I have to do a bit of research on this objective first. I don't have any Nikon eyepieces or photo eyepieces, so it's usefulness to me would be based on how well it works on a bellows without corrective optics.

Hi Rylee
Neither objectives need any corrective optics as they are both finite objectives. It screws straight onto the bellows via an RMS to M42 adapter. Such as this cone adapter (http://www.ebay.com/itm/RMS-Thread-to-M ... 5192a1613c) or plate (http://www.ebay.com/itm/200470968028?ss ... 1439.l2649). I also have the x5 and x 10 objectives in the same range but because of vibrations in my setup, they are as far as I go, in terms of magnification.

That looks like the CF M Plan Achromat ELWD 40X, part #78776, described HERE, page 2.
I have the BD version, for example as shown HERE with sample images in this other thread.

I think BD lenses have their own thread style, not RMS, and that there is a second opening for a light source.
If you've been mounting them directly to an RMS adapter, then they're probably the regular versions. In terms of the image quality, though, I don't think it would make any difference. I think the optics would be more or less identical to the BD version.

From images I have taken, I have seen no chromatic abberation, except on the striations on the scales of a moth wing!

All correct. The BD's are designed to illuminate the front of the subject from around the lens, using light delivered from inside the microscope and routed inside the barrel of the objective but not through the optics. It's called "episcopic darkfield", as opposed to "episcopic brightfield" where the illumination goes out through the same lens where the image comes back. The difference is apparent if you look at a mirror: in brightfield the mirror is bright, in darkfield it's dark. The BD lenses have a different mount that provides space around the outside for the illumination.

The Nikon CF objectives do not require corrective optics.Rylee Isitt wrote: I might also be willing to pay the full price, but I have to do a bit of research on this objective first.
