  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Here is it in action - works very well, it's clear when the distance is exactly right and you can see how far it is out if you need to use shims.

Looks like it works great. BTW, that sure is a fancy focus hook. Did it come with the cheese stick?
 
Have an experienced lens tech measure it out for you before trusting it. I know someone who got three and they were all off (quite a lot).

Really? That's insane. For a collimation device not too leave the factory in a perfect condition really, really does not bode well.

Exactly - but they eventually got it right and it's a really nice piece of gear. A bit on the expensive side, though.

I like the concept. But for even one too leave the factory and be out when they're claiming it gets you within 1 micron makes the thing wholey unreliable. What's the use of a collimating device that requires you too check it's collimation?

I'd be interested too hear back from Cail and any other users as to whether theirs performs flawlessly or not. I'd also welcome a comment or two from Denz as too whether they've changed their QC for new units.

I'm the one Tony mentioned.
The Danish importer recieved 3 units and I got the second one delivered.
When I tested it, it was showing as all my cameras was off by +70 micron!
Took me half an hour to realise my collimation was correct, and that the FDC was off.
I set up an appointment with the Danish distributer, and tested the third one, which was still at his shop.
That unit was showing +50 micron.
All three units were sent back to Denz.
When they came back and I tested, two were spot on at 52mm, but the last was now at -30 microns.

My own unit was one of the units that was now spot on, fortunately:-)

We have been using this for about 3 weeks now, and I must admit that it greatly dimishes the time needed for camera check up, and the job of collimating the cameras prior to sending it out can now be trusted to others, as it's now very intuitive.

And the finish and mechanical construction is very very good.

This process has beeen a bit terrifying, but it could just be that something happened during transport.
I'm still checking the FDC often to make sure it's keeping it's calibration.

I'm pretty sure that there is a mistake in the specs- the scale shows .01mm precision which is 10 microns as 1 micron is .001mm. So it looks like the unit was 70 microns of and 50 microns off, respectively. Just think about it -human hair on average is 30 microns...
 
My bad, writen in a rush...you are correct +50, +70 and -30 microns.
The corrected units were spot on though :-)

One worrysome thing about using this tool is that you realize how much the image centering varies from camera to camera...

The Optimator does look very interesting especially for testing the properties of the chip seating.

Is there any demo units available?

Having tried to match 3d with motion control, I can tell you it's a huge issue to some of us.

There is a set complete with scope to check the Optimator calibration(so you don't have to send it back- easy enough to calibrate yourself) at Band Pro Munich. More coming soon..
 
Just spoke to the guys over at Hub - their unit arrived in perfect alignment - checked on both our RED and one of their 435s.

No longer shall we be fiddling with a 10mm Ultraprime and allen keys!
