[garjor]

May I use one of those M42-M42 helicoids as a focuser for a MTO 1000mm mirror lens?

Now it is a pain to move the whole barrel but I do not know if one of those helicoid will allow micro focusing or not

I know I have to allow past infinity focus to compensate the longer lens-sensor distance (it is explaided here )

I do not want to buy one if I do not know it it works a I expect or not
Regards
Jorge

PD After several tries I managed to put the URL

[Attila]

[garjor]

I will ask a different way:

If you turn 360 degrees the ring, how many milimeters does it extend?
Always the same amount or it depends of the whole lenght or the helicoid?
Regards

[no-X]

cca 270 degrees extends the helicoid fully

This certainly depends on teh type of helicoid you are interested in.

1) you need to determine which total helicoid extension you need (maximum / minimum i.e. longest / shortest).

2) you need to select a suitable one in that range (usually a compromise needs to be accepted in terms of close focus, since infinity focus, or a bit more determines the shortest length = extension needed).

3) you can find out which total angle that selected helicoid needs from minimum extension to maximum extension (360 or 500 or 720 or whatever degree).

4) it is up to you to decide if that is fine enough or too course.

How can one calculate the size of helicoid needed for any given FL to achieve infinity? Is there a simple way to do it?

If you have the register length ("Auflagemass" in german) for a given length, yes, otherwise measurements or an approximation has to be used.

Denote:

RLL = Register Length of a Lens
RLC = Register Length of a camera (Nikon, Canon EOS, 4/3 - you name it)
HLI = Helicoid Length at Infinity
AL = Adaptor Length (usually a few millimeters thickness only)

then:

HLI = RLL - RLC - AL

that also means that HLI cannot be negative and has to be at least some 15mm or so (shortest Helicoid I know of). This also explains why with some lenses infinity focus cannot be reached.

If RLL is not know, the following procedure allows to measure it approximately:

take a white sheet of paper, a ruler and your lens, hold the lens in front of the white paper in a darkened room and point the lens front with fully open aperture to the outside to a bright object (can be the sun also, but be careful not to burn the paper) at least 100x further away then the focal length of that lens until you get a sharp image on that paper. Now measure the distance from that paper to the flange of the lens (end of the thread or mount (could be bajonet etc.) - not just the physical end of the lens!). This is approximately RLL.

If you want to use that lens for macro shooting, say at 1:1 magnification, then point the lens using the same procedure to a bright lamp (desktop tungsten works well) until you see an projected image which has the same size as the original lamp (us the visible lamp filament for instance (stepping down helps if the image is too bright). Keep that position and repeat the measurement at mentioned above). That gives you the approximation for RLL(1x) at magnification 1x.

Now we get

HL(1x) = RLL(1x) - RLC - AL

where HL(1x) denotes the needed maximum extension of your helicoid and

HR = HL(1x) - HLI is the range your helicoid has to cover when turning from infinity to 1x magnification (you can replace 1x with any wished factor of course). If HR is too long, it has to be replaced with a shorter helicoid and a tube of fixed length (say to reach only 0.5x for instance). [Example, if you would need HR = 50mm and the longest helicoid you can find is 25mm, then add a 25mm tube to reach 50mm]

Wow, that's just excellent information to have. Amazing really the great things everyone shares here. I've been quietly reading and reading. I'm a little in awe after going through this thread.

Perhaps I'll post more soon. You all seem like a friendly lot...
