What the hell?

I'm sorry man, but Jason is right, you're spilling alot of invective here on something that is really your own fault. When you buy second hand be careful, the guy you bought it from should have explained it, but its easy to forget stuff.
Nevertheless the solution has been explained to you. You only need to find out if you go to 62mm or 67 and someone here should know. If you look around on the SG website I bet the info is there also.

Five minutes on the web and you could find the step down adapter and have it shipped overnight or in 2 days for very cheap. Now you've lost the weekend.
I think there is a place called <camerafilters.com> that's very cheap.
 
you can get your stepdown ring from B&H and have in time. just pay for overnight shipping.

I think you said you bought a Rev2 SGpro, which, someone correct me if I'm mistaken, was 2 generations ago for Wayne. So may have been reading info about the Rev3. Your cam wasn't available at the time of the Rev2 being released, so you may run into problems.

Search for info on the Rev2 specifically, you'll find the exact thread size you need to match it for your XHA1.

I can't speak for the condition of the equipment you bought, but everything looks rights, as far as build.

you should line it up as is until you get the ring, as suggested previously in the thread, since you don't have a flip unit, and will need practice getting used to seeing the upside down image produced. it's awkward for a while.

but try to put something around the seam where you cam meets the adapter, to limit the amount of dust.
 
just ask wayne from shoot35 (info@sgpro.co.uk) advice he'll defiantly help you out and give you your best options!

good luck!
 
Lining it up doesn't work. It doesn't tighten enough for it to not wobble. I tried lining it up and not moving the equipment and I can't get the image to focus at all. I don't know what I'm doing wrong? I'm obviously not trying to focus with my camera, but it doesn't look right.

You have to focus your camera on the GG, where the image is projected onto.

I assume the long rods have some flex to them? mount the camera on and set the whole thing down on a table, or whatever so it's not moving or flexing.

you'll have to roughly focus the SLR lens on something. you should be able to see the image in the adapter before putting the camera on. once focused, mount the camera, and make sure you keep it in the same spot so you can stay as close to focused as you were. with your camera mounted, and zoomed in to where the edges of the spinning disc start to disappear, you should be able to start adjusting focus manually on your camera until the image is sharp. make sure to turn off your optical stabilization. I've read some people using auto focus to get in the ball park, then fine adjust manually. and remember your zoom and focus numbers once you have them.

Hopefully someone experienced with the Rev2 can give you some specific advice. and what you might run into with your camera.

good luck
 
I guess I can play around with it until a step ring comes. Does anyone know exactly what step ring I need? I can't seem to find much info about this adapter for some reason...
 
It is normal to see the glass and the motor, you just have to zoom in further.

The SGpro tube is designed to go on 72mm threads without a ring, but you can use a step ring to attach to a smaller (or bigger) camera.

If your camera does have a 72mm thread and there is no step ring on the tube, its possible there is either some dirt in one of the threads, or a dent. Also check to see if you have a clear or some other filter on the camera which might not allow another filter to thread into it.

Since the thread is so fine, any bits of dirt or a dent will stop it from threading in. Maybe get a nice clean toothbrush and brush out the threads and see if that helps...

When I say that it will not thread in, I mean that there is a good centimeter gap when trying to fit the end tube to my camera threads. It's THAT bad. Right now, I have some double sided tape (with a foam lining) that I managed to use to rig the tube to the end and for now, it works.

This is what confuses me. Like you said, the tube is 72mm and my camera is 72mm, but the tube is way too small at the end.

Also, just a quick question, what exactly does the spinning glass do? What purpose does it serve?
 
Mm. Odd. Which camera do you have? You sure you removed the hood etc etc?

The SGpro tube is unlikely to be the wrong size, its more likely that you are either misinformed regarding your camera, or there is a step ring or something attached to the camera. Have you tried measuring the tube and seeing what it comes out at?
 
I bought the camera brand new. I never had a step ring for it. I will measure the end of the adapter in a moment here. This is really strange.
 
As I recall ( don't have it anymore) , my Rev2 tube was 62 or 67 and had a 72mm adapter ring installed on it from the get go. You might not even notice its there.

Actually, I'm willing to bet money that it was 62mm, because I still have a little series of rings I made when trying to adapt it to Brevis Flip. Just looked at those rings and they are 62mm.

But there isn't one on the tube. Is it something that was easily removable? If so, I would think that the previous own of this took it off and forgot about it and never put it back on.
 
As I recall it was removable but there may have been something like a screw holding it in place - tell the truth i don't remember. Have you talked to the guy you bought it from?

He told me he figures it's my cameras thread size. Whatever, I will just get a step ring.

Actually, I have a question that may sound stupid. What is the spinners (motor and glass) function? What exactly does it do?

The image from the 35mm lens is projected on the spinning disk. It spins to hide the grain which would otherwise be visable if it were not spinning.

The camera then records the projected image from the disk. It will be upside down and flipped horizontally, but you probably already knew that.
 
my guess is you have the Rev2 with the older achromat, which was in a tube smaller than 72mm, since the achromat was like 57mm or 58mm.
 
Have you tried your local photography shops around your town. A lot of times you can get step up/down rings there. I purchased all my step rings from Samy's here in L.A.. But you know what you need..you might just call around a few shops. The price is pretty cheap for the rings and it is very common for shops to have it.
 
I ordered a stepring online today since there are no camera shops around here.

As for now, I am able to use my setup until I get the ring. I have some double sided tape (with foam) and it's very sturdy. I am able to play around with the adapter and get a feel for it. I am having some problems getting a large depth of a field, rather than a small. It's hard to keep objects you want to keep in focus without making them out of focus. I can now see how much pre-planning you may need to just use an adapter for some shots.
