Adapters to connect cone to Raynox 250 to ex tubes

axle01 · Post by **axle01** » Thu Apr 06, 2017 12:04 pm

I have a RafCamera M25x0.75 female to M42x1 male thread adapter cone and need the required adapter rings to connect it to a Raynox 250 then to the m42 extension tubes but unsure of the thread sizes.

Can someone tell me (in order) what rings I need to go from the ex tubes to the Raynox 250 to the cone.

I have the camera to m42 adapter.

I've also seen that if the Raynox lens is mounted in reverse it produces a better image, if this is so what rings would I need (in order)

I had all this gear but it was all stolen back in Feburary so I am starting again but carnt remember The ring sizes.

Any advise will be great fully appreciated.

Adapter setups for both orientations are shown at http://www.photomacrography.net/forum/v ... hp?t=18145 and discussed in subsequent replies in the same thread.

Rik I'm having trouble finding a M42 female to M42 female step ring.

Also a 43 female to 52 male

Try ebay seller jinfinance.

For female to female connectors you may have to use a "long" female and screw into it from both sides, or go via some intermediate size.

I've had Rafcamera do a lot for me in the past so I just contacted them and if I have to use a m42 ring I can remove one from a camera adapter and remove the threaded part

Thanks Chris
