Hi Photographers,

Just received the last piece for my reversed lens set-up for macro!

If anyone would like to try this as well, it is a lot of fun, and is quite inexpensive.

I have made a list of the items needed, all purchased off E-bay, and have attached it below.

I blew a couple of bucks on the filter since I'm very dedicated to B+W, so I've chosen one of their cheapest models, but a no name brand 52mm filter can be bought for around £2 instead.

It's a quite straight forward job, assembling the lens set-up, but I wanted to protect the rear of my lens, so I bought an extra rear lens cap which I then modified to become a new filter and aperture -holder.

The rear was cut of and filed down until it was flush with the first narrower diameter area inside the cap.
Then I filed down the stop point on the side of the cap, so it can screw completely clockwise in the lens, activating the small tabs that allows the aperture adjustment to be turned.
Afterwords, I screwed it on the lens, so I could measure where I had to drill the hole to keep the aperture lever back (Lots of people holds this lever with their finger while photographing, but since I made a filter holder for mine, I didn't mind, not having that to think about that.) I then found a small screw i shortened up, and screwed it in.
The narrower area of the cap was now enlarged with a Stanley blade, to eventually fit the 46mm step-up ring, which I glued on with super-glue.
Now I have a filter holder which I can use on the rear of any FD lens!

I am still working on how I am going to trick my Canon 1Ds into using the lens, but it works brilliantly on a 500D.
I have bought a "chipped" macro extension tube set, and will try this on my 1Ds, to see if it works.
I would like to add, that it is possible to photograph with the 1Ds, as long as you don't screw it onto the camera completely.

An excellent post. Great idea on the screw to manipulate the old Canon FD-mount lens's mechanical diaphragm control lever.
