comment Why are SLR lenses so much larger than Sony E-mount lenses?
At the moment this is more comment/conversational than answer. Could you improve it to turn it into an actual answer without any additional questions?

comment How can I batch save images with reduced colors in Photoshop?
I'm voting to close this question as off-topic because it is related to graphic design rather than photography.

comment Where can I find the maximum camera weight for my lens?
If there was any other information on this, I wouldn't be asking the question. I've been investigating this camera for months, it was only just released this month (first cameras finally started shipping, from various manufacturers.) I've covered all the bases. Called manufacturers and asked them about this. This is why I am asking the question. Seems no one actually knows what kind of load the EF mount can really, actually handle. I guess my only real option is to call CPS...

The manufacturer sells the camera with a 68mmx1 threaded mount. It is adaptable to just about any configuration by using adapters. The camera can be used bare, or with a filter wheel (few different options there), with a third party filter wheel (even more options), with an off-axis guiding port adapter, as well as with adaptation (with or without a filter wheel) for the EOS EF mount, Nikon F mount, M42 mount, etc. I don't think Moravian has actually done any confidence testing with their EF mount option, though.

Hmm, I guess I'll take a look. If I can join, that would certainly be beneficial. I do think that there is a very slightly tilted element in the lens that needs fixing. It hasn't affected my bird and wildlife imaging, but it does affect my astrophotography. I haven't really wanted to send it in due to the risk of mailing something so expensive...but maybe with CPS, I could get that fixed.

No fittings of any kind. It is primarily intended to be attached to a telescope, so the only point of attachment is the opening to the sensor. On a regular telescope, you would usually use a minimum of a 2.5" (63.5mm) focuser, but if not a 3" or 3.5". Those are more heavy duty and stable, with high rigidity and they are designed to handle loads of 8lb up to 30-40lb. The Canon lens mount in it's total size is comparable to a 2.5" focuser, it's just that it's capacity is totally unrated (officially), and the mount is usually bolted onto the lens, rather than being like a solid focuser drawtube.

No, I use the camera bare, as I like the big wide FoV it gives. So it will be camera + FW attached directly to lens.

Michael, while I won't be attaching the camera during transport...there is still some moving around. I've updated my question a bit to clarify the use case.

FYI, this particular camera does not have a tripod mount. It is a scientific imaging camera designed for microscopy, medical imaging purposes, astrophotography, etc. It is quite large...I'll see if I can get some images added to my question to demonstrate the size of the camera, size of the filter wheel, and the odd conundrum it presents to supporting the camera.

Regarding CPS...I would love to be a member...however as far as I know, in the US, they require that you be a full time working photography professional in order to join. I have been published, twice, in magazines coming out next month and the month after...but that would only make me semi-pro, and a baby semi-pro at that. I don't think I qualify for CPS, despite the lens.

comment Where can I find the maximum camera weight for my lens?
Thanks for the link, Octopus. It is relevant...sadly, it also does not provide any actual specification. ;p I need an actual value, and it seems manufacturers are VERY unwilling to actually provide one. Liability issue, I assume...meh. Does anyone know if they really do intentionally build in extra support for small forces from dropping, etc.?

revised Where can I find the maximum camera weight for my lens?
Added example of my mounting rig and explanation of potential forces on camera.

I don't mount the lens at one point. I built a custom rig to mount both the 600mm lens and a guidescope and camera. See my question edit for a photo of the rig, and more.

Add that point back in.

comment Why are crop lenses indicated with focal lengths they don't have
@Goat: The issue is not that people are getting offended. It is simply that your answer is incorrect. You state: "The properties of a lens always depends on the focal plane." That is total nonsense. The properties of a lens depend on the lens! The size of the focal plane (sensor, I presume you mean) has nothing to do with the lens...a lens is a lens, a sensor is a sensor. A big sensor covers a larger percentage of the lens' image circle...a smaller sensor covers a smaller percentage of the lens' image circle. Smaller sensors, for a given focal length, simply crop.

Seems TFuto did an admirable job eliminating the discussion aspects. Seems good to me now...if you wish to add more useful answer details, feel free, but try to keep the "chattiness" down.

This is more discussion than answer. Could you turn this into a true answer, without the discussion aspects?

comment What is a “diffraction limit”?
@MichaelClark: You don't. I only did that to simplify the example, nothing more.
