Thanks Conkar. the stuff has been discussed before.
As of now the update is this:
Javier had helped in locating an affordable focus rail and a micrometer.though due to work issues, I could not buy it and bid properly.
My cart currently holds.
1. the MPE Lens.
2. the Manfrotto 454.
3. A ball head for the rail.
4. wimberely plamp replicas.
Should I purchase a third party tripod collar? the manfrotto is on hold mode as of now. Should I go for it before I step into the bigger products like the RSS?

Is the MP E worth over the raynox?

That's covered at Lenses for use at 4-5X on an APS-sized sensor.crayfish74 wrote:But what about MPE 65 Versus Canon 100 macro 2.8 + 10 x nikon micro lens or 4x micro lens ?
At 5X, the Canon 100 macro 2.8 + 10 x nikon micro lens is much sharper than the MP-E 65 (test images linked in the first posting of the thread).
At 2X, I haven't run a direct comparison. Based on the effective apertures, I would expect the MP-E to be a little better at center. The MP-E should have much more uniform coverage, center to corner.

And for a full frame as 5d mark ii what will be the best combo? The MP E -65?
Best

The 100 mm + 10X combo will not cover full frame, so that's out.crayfish74 wrote:And for a full frame as 5d mark ii what will be the best combo? The MP E -65?
This leaves the MP-E 65 giving best performance, among the objectives tested in that thread. The Mitutoyo M Plan Apo 5X NA 0.14 on 200 mm tube lens (not tested there) will have less CA than the MP-E 65. Resolution should be about the same as the MP-E 65 but I haven't run the experiment.

f/10what will be the effective aperture for the macro Canon EF 100 mm L IS+ nikon infinite BE plan 4X and 10X?
The formulas are that
a) camera-side NA for an infinite objective is subject-side NA divided by actual magnification
b) camera-side effective f-number is 1/(2*camerasideNA)
Put them together to get that effective f-number = actualMagnification/(2*NA)
Actual magnification = rated magnification * tubelensFL/200.
So, the 4X NA 0.10 on 100 mm is actual magnification = 2, with effective f-number = 2/(2*0.1) = 10.
The 10X NA 0.25 on 100 mm is actual magnification = 5, with effective f-number = 5/(2*0.25) = 10.
