  • 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 :)

Birger Lens Mount Reservations

Need a long zoom.... preferably 70-200 2.8 L

Will you be supporting collimation for that lens?

Please note that the lenses for collimation are not the only lenses that will be supported by the mount. Erik mentioned "relatively wide angle" lenses -- presumably because the collimation process will be done indoors?

I thought this was funny too... Aqua politely reminded me that we should look through the "Birger "I didn't get a confirmation for my order yet thread" and assign confirmation numbers to any communications in that group if they were missing in the system.

Amy and I will be here on Saturday to get this email out, so we can enjoy the monday Memorial Day holiday that we celebrate here in the states.

Virtually all of the high end Canon lenses will be supported by the mount itself. Collimation support means they have gone through an extensive test procedure to develop algorithms to allow you to easily collimate the mount. You normally use a wide angle for collimation because it is more precise - wide angles have a great depth of field in the picture of the outside world but a very short depth of focus at the sensor so it is easier to tell if you are right at the proper flange focal depth.

All he is trying to do is give you a fairly good choice of lenses to use for collimation so that most everyone will have one of the collimation tested lenses in their kit. In other words if he only did the math for the 24-70L many people might not have that lens, but almost everyone will have or have access to one of the lenses he has already shown and he is just asking if there are other really common wide zooms that he did not think of.

I really appreciate that you are going though the list of "confirmation not received", that addition has saved me a lot of stress.

Can't wait for the mount!

Cheers,

ok, Aqua. I'm just new at this. That makes perfect sense. Since I have some of those pictured, I should be covered. Thanks!
 
Is that the 16-35 v1 or v2? Does it make any difference?

We are supporting collimation with a bunch of lenses. Grabbing data to build the the many more of the statistical models today. Look at all that glass. We will also support the 17-55mm f/2.8, just don't have that lens here today. Does anybody not have one of the lenses pictured, and want to propose another relatively wide angle, constant aperture zoom manufactured by Canon that we might want to add to the list of lenses supported for collimation?

Does it have to be a Canon branded lens?

Really wide and has a constant aperture:
1) Sigma Fisheye 8mm f/3.5
2) Sigma 15mm f2.8

version 1 or 2. canon released the v2 in the last year or so. Supposedly it's better than the v1. From squinting at the picture it looks like a v1 to me, but I only have a v1 so I don't know for sure.
