The E-mount adapter I'm using with my Chronos 1.4 has an issue with the three compression screws on its base constantly loosening with the slightest provocation. This makes the lens "wobbly" and is often enough to affect the focus, leading to many ruined shots. I have to carry a jeweler's screwdriver everywhere I go to keep them tightened, but it doesn't take much to re-loosen the screws.
This isn't really a problem with the Chronos per se, but is an issue created by the very small-diameter C-mount having to support the weight of DSLR lenses. I'm using either a Canon 10-22mm or Tokina 11-16mm lens with my Chronos - not huge lenses, but big enough that the stresses on the small C-mount connection are enough to work things loose easily.
Is there a good C-to-E mount adapter that would be more secure, or maybe some type of cinema-like rig that can support both the camera and the lens on a common frame? Thanks for any suggestions!

I am somewhat puzzled by the fact that you are talking about an E-mount adapter/ C-to-E mount adapter, as the only mount referred to commonly as E-Mount is Sonys Mirrorless Camera Mount, at least as far as i am aware. and that sony-E-Mount cant really be used on a C-mount Camera body (even CS-Mount would be tricky, but at least mostly possible on some cameras)
.
Now given the Fact you also mentioned DSLR-Lenses, and the Canon brand, i assume you mean some kind of Canon DSLR-Mount adapter for C-Mount (not a Canon User Myself, but i guess they have an mount called EOS or something, so you maybe mean that one?).
.
while i now also dont really know what kind of adapter / brand of adapter you are currently using, i still can generally reccomend the Metabones Brand:
https://www.baader-planetarium.com/de/c-mount-canon-eos.html
(German Link, but you will for sure find one sold on B&H or something similar, depending on where you live)
Only thing to keep in mind, is that this adapter does not allow for any kind of apperture control, unless the lens can do it itself (for example an Aperture control ring on the Lens itself), as most modern Canon lenses require some kind of Electronic connection to the camera/ adapter to do that, which is also why i usually stay away from Canon mount lenses myself.
.
I personally own two of Metabones Speedboosters and got my hands on a few of their other adapters bevore, and they are usually very high quality, and i never heard anyone say something bad about them, besides beeing somewhat on the expensive side compard to some other brands. if you are looking for a good and reliable adapter, i would reccomend having a look there.
.
Hope this is the correct adapter you needed, otherwise, let me know or upload some images of the one you are using.
.

As far as additional lens support goes, most flexible, standardized and streamlined solution would be to by some standard Rail-Supports which are also used for DSLR-Style Cameras with bigger lenses and Cine-Cameras. There are quite a few different Styles and Designs of those, but most of the not too exotic ones can usually be bought for reasonable prices, Professional and Big-Name-Brands can get somewhat pricey quickly however.
Cant really reccomend a specific one, as they can be quite different and its a lot about preference and whatever you are doing with your camera/ Lenses, to find the best one for you.
Best would propably be to just put "lens rail support" in your Search Engine of choice and look up some images that come up, and go with whatever you like most, if you actually need additional lens Suports.
Those Rails are used a lot in Cinema Filmmaking, so i guess thats what you are looking for.
.
Didnt sound like you are actually putting the Camera in a lot of physical Stress/ acceleration / Forces, but just a bad quality adapter. but if you do, consider a full cage which fully supports the Lens all around, will most likely need to be custom made for this camera and your specific Lens, but i guess thats very much overkill from the sounds of your initial post.
.
.
For a quick and simple fix of the Problem i can also reccomend to just use someting to secure the Screws with, once tight.
I seen a lot of People use some Loctite Products for keeping all kinds of Screws from moving, which usually works really well. Now i never actually used any Loctite Product myself, but i know they offer a bunch of different stuff. You dont want the kind of Glue, that just will fix the Screws in place forever to never be loosened again, but rather the one, which just prevents the Screw from loosening itself, in case you actually need to readjust or even clean something for example.
Dont really know a name for that stuff sadly, or what it is exactly.
There Should be different brands of that too, but Loctite is the one that i know of, which has that for sure.
Now given your adapter is atleast half decent and the problem is actually just the screws itself, this might save you some money and Time if it works.

Thank you for the suggestions, yes you are correct - I wasn't using the right terminology. I am using Canon EF lenses with this adapter:

i have not owned the Fotodiox or Metabones one of those exact Adapters, but i assume the Metabones one should be at least a bit higher Quality. Fotodiox one should however still not be all that bad and at least "useable". If i where you i would first try to fix the Screws in place with something if you are otherwise happy with the Adapter and your overall setup. Rails and other supports are great for some things, but can and most of the time will add a bunch of Bulk to the size of the whole Camera Rig, which isnt allways what you want.
-
I have a Fotodiox adaptor for Nikon and some quite big lenses (thank you eBay) and never had the adaptor go wobbly on me, so it might just be that you have a faulty one?

Yes, i actually also thought about that. Wasnt sure about what Adapter you where using from the initial post, and for some of the Real cheap and bad no-name China stuff things like that could be very well possible, but Fotodiox isnt exactly known for bad adapters or anything. While (at least for me) Metabones is somewhere on the Top end for general purpose Lens Mount adapters, Fotodiox is still on the List of reputable brands for me.
.
if you got yours brandnew, you can maybe also try to contact them, and get it replaced. Could at least be worth a try.

Just an update to this thread. I ended up going with a CAMVATE rail system to support the camera and the lens as one rigid unit. This seems to have solved all of my focusing issues by eliminating all possible sources of movement. The extra weight makes handholding for more than a few minutes at a time awkward, but I have production-tested this setup on the road during the past month, and it has held up very well. Thanks to all who offered suggestions!
-
Happy to hear, that this worked out for you and you found a good solution!
I can feel you with the weight thing...
I attached a external Monitor to mine and use it with a Speedbooster and Full-Frame Lenses, which adds up to a decent bit of weight as well. Will have to figure out how to attach a Camera strap to it at some point, to carry it around the Neck, as it does indeed get pretty heavy fast. My issue isnt shooting itself, but more holding it in one hand at the Built-In Grip when walking around for 5 to 15 Minutes or something.

Same problem here, but not solved yet. Anyone have a fix for that?
I have this adapter, (https://www.amazon.de/Fotodiox-Adapter-Clicked-Aperture-C-Mount/dp/B00VIVXL2E) btw.

Update after shooting with this rig all spring and summer. In addition to the Camvate rail system, I bought a different brand of lens adapter - a Vello (first one was the Fotodiox). The two brands are very similar.
Sadly, even with all of the bracing from the rail system, the simple act of repeatedly setting the camera down on the passenger seat of the car over months of use was enough to start loosening things up again. The Vello adapter screws now require re-tightening after a day or two of use, and the camera's lens mount actually has started rotating slightly. With the wide-open aperture (and associated narrow depth of field) required to get useable exposures in outdoor daylight, these even very slight movements often require refocusing the lens - a task very difficult without very bright daytime lighting conditions. The loose lens adapter screws often allow the lens to wobble on its axis, meaning one half of the image is in focus, the other out of focus.
I have added a zip tie to further secure the lens to the rail's y-support, but this is only a stopgap. My next measure will be to install a tripod head in my car to perma-mount the rig, so that the lens never encounters *any* lateral force. It appears just the weight of the camera resting on its side is enough to work it loose over time. It certainly appears that a native mount is going to be the only long-term stable solution.
Again, I usually need to set focus during the day and rely on that setting for the evening and nighttime. Getting a good focus set in the dark, even when the camera is set to 30fps, is many times impossible.
-
In case you are actually considering getting into Native C-Mount lenses, i went through my List of C-Mount Machine-Vision/ CCTV-Lenses and Searched up some Online Prices/ Places that sell those. I only listed Lenses for 2/3" to match the Chronos 1.4 Sensor Size Specifically, and according to you initial Post Similar Focal Length to your Zoom Lenses. Listed are Focal Length from 8 to 16mm, sometimes i included shorter ones too.
Big Advantage of those C-Mount Primes specifically for that Sensor Size is, that you usually can get much Faster and Smaller Lenses than with Canon Mounts. Most of the Lenses Listed below have an Aperture of f/2.8 or way faster.
. Most of those Lenses do come with some kind of Resolution Rating, but i personally would try to get something with a Higher Resolution Rating than what i actually need, because some of those Ratings are somewhat Questionable and sometimes more of a Sales Statement than Facts for Some Manufacturers. Note that the actual Wording for Resolution goes something like (rough translation from German by myself) "Minimal Pixel Size at 30% Contrast", which i quoted as "Pixel-Pitch" in this List. So dont just rely on those Resolution Statements and expect them to actually Match 2MP, if they are rated for that. They might in some/ most situations, but dont in others.
Now, going way overkill with these Lenses Might also dont Make too much sense, as Budget probably also isnt infinite, so i just listed about everything that would make sense on Paper. Watch out for the Compatibility note i put on the End of the Post!
.
Let me know if you need something more Specific, or if that List helped you any. Can List Plenty more C-Mount Lenses, that might also make sense, if you ever plan to go with some other 1" Camera or even 4/3" like the 2.1.

Those are for 2/3“ and are recommended for a Pixel-Pitch of 4,4µm or less (the 1.4 has 6,6µm; so the lens should technically match the Camera Resolution).

These are Rated for 5MP Resolution 2/3” Sensors, recommended for a Pixel-Pitch of 3,4µm or less.
Basically the Same Lenses like above, but should be Sharper, at the cost of a Smaller Aperture.

These are also Rated for 5MP @ 2/3” Sensor Size/ 3,4µm Pixel-Pitch, but are meant for Outdoor CCTV, which means they will provide the Same Sharpness also in IR-Lit Night-time Situations (given your Camera even captures them). Basically the Same Lenses, but corrected for a larger Spectral Range of Light, with a Larger Aperture than the above 5MP (Standard) Lenses.

These come in GMTHR- and GMXHR- Variants, but only difference I can find, is that the GMXHR- are rated 3MP according to my List, and the GMTHR- ones are only listed as 2MP Resolution, these are also cheaper by a little. The Website however says, both are 3MP, not sure what is correct here.

Rated for 12MP@ 2/3” Sensor Size, Should be the Sharpest, but not sure if you would even be able to tell much Difference on the Chronos 1.4 Sensor, because of the Low Sensor Resolution. Should however be Stellar Optics, and offer very short Minimum Focus Distance. Plenty of overkill for the 1.4 though.

Rated for up to 2MP @ 2/3” Sensor Size, so Resolution should match the Chronos 1.4 Sensor.
These Lenses Also Feature a Short 0,1m Minimum Focus Distance on rather Inexpensive Lenses, which could be useful, if you ever plan on doing any kind of Closeup / Wide-Angle Closeup Work with them. A lot of my Personal C-Mounts have MFD of 0,15 to 0,3m, which is really nice to have, as I rarely feel the Need to even get dedicated Macro Lenses.
The 16mm one of this Series should also be available as FL-CC1614A-2M, but I couldn’t find it Online. The Version without the –A on the End has an Minimum Focus Distance of 25cm, which is still not too bad.
These sadly seem to be out of stock everywhere I looked currently, and on-Request-Only Order.

Rated for 5MP @ 2/3” Sensor Size, should be Sharper than the 2MP Versions above, but less different Focal Length available. Bigger and heavier also.

Schneider-Kreuznach High Resolution Compact Prime Lenses

These are rated for 3,5µm Minimum Pixel Size, and my List says 3 to 5 MP Maximum Resolution, whatever that means.
Should be well corrected and Robust Lenses, with an Focus-Locking Mechanism that for sure shouldn’t come Loose.
Available in Focal length: 4.8 mm, 8 mm, 12 mm, 17 mm, 23 mm, 35 mm
But I was only able to track down Online Prices for the 8mm and 12mm Versions from a Quick Search.
B&H lists those as “This item is noncancelable and nonreturnable.” Btw.

Tamron Standard C-Mount Lenses

These are Listed as “up to 1,3MP Resolution at 2/3” Sensor Size” in my List, Website says 1 to 2 MP Resolution, so I doubt that you would be able to get the Full Resolution Potential out of the Chronos 1.4 Sensor with those Lenses, so I would not recommend buying those. Especially, because they cost more new than some of the Other Options, which seem to be much Sharper just from the Mega-Pixel Ratings those are sold at. However, If you are Able to find those used, those are usually pretty cheap, so that might be an option if you don’t want to spend a lot of Money. But don’t expect crazy amazing results, if they even Rate it at 1MP, actual Resolution might be even worse.

Maybe even Cheaper on Ebay and such, haven’t searched there yet, just did a very Quick Search.

Tamron High Resolution Lenses with Small Minimum Focus Distance

These are rated for a Minimum Pixel Pitch of 2,5µm. My List states a Resolution of 10MP @2/3” Sensor Size, but the Website does only mention a Maximum Resolution of up to 6MP on the Page of the 8mm Lens, so again not too sure what is correct here.
Tamron also has an even more Expensive Series of C-Mount-Primes, which are Specifically Vibration-Resistant, didn’t list those here.
.
.
An important thing to note is, that some of these Wide Angle-Lenses will not be Compatible with a Standard C-Mount to CS-Mount Spacer (the 5mm Ring that came with the Camera) because they have a Rear Element that Protrudes too far into the Mount. To make sure they fit the C-Mount Spacer Ring, I Recommend To contact the Seller or Manufacturer and ask, before you actually buy any of the 12mm or Shorter Focal Length, everything longer than 12mm should usually be fine (only lenses above 12mm Focal Length I know with Super Huge Rear Elements are Super-Fast C-Mounts like the 25mm 0,85 and such, but there are for sure other ones i dont know about.)
-
Also did some more digging online, searching for C-Mount to Canon Mount Adapters without those adjustment Screws, and the only two adapters i was able to find without those are these:
https://fotodioxpro.com/products/efa-c-p (https://fotodioxpro.com/products/efa-c-p)
https://www.adrianololli.com/articolo.asp?ID=2672 (https://www.adrianololli.com/articolo.asp?ID=2672)
Both only show a Single Image, that shows the C-Mount side, but if the Images are accurate, those should be a Solid one-Piece Construction. That might leave the Lens in a Weird Rotational Orientation, but will at least avoid the Constant loosening of the (on that Adapters apparently Missing) C-Mount Rotation Adjustment Screws.
To be sure those are actually one-Piece Designs, might ask for more Images before actually ordering one of those.
.
Only other thing i can Recommend, is to think about using something like the Style of Adapters SergeyKashin Posted Images off. He said, he is selling those in an Other Thread, which he later deleted, so not sure, if he is still selling those. In that Same Thread Mostafa from Krontech also announced, that they are working on an official MFT-Mount Adapter/ -Plate just like SergeyKashin showed, but no official Release Date is known yet, from what i am aware. I also Posted a 3D-Printabe Mount of the Same Style in this Thread:
https://forum.krontech.ca/index.php?topic=615.0 (https://forum.krontech.ca/index.php?topic=615.0)
Sadly, the original exact Macro tubes, for which Metal Mount the 3D-File was made is no longer Available as it seems, so that would maybe need to be modified.
Otherwise you might just need to wait until Krontech releases their MFT-Mount or get something like the Adapter Plate that Turns the Chronos into an Native Canon Mount (Should be the Most Sturdy Connection, if you insist on using your Canon Mount Lenses).
.
Bayonet Style Mounts still will always have some kind of Play usually (some Amount of Lens Sag on very Heavy Lenses is usually noticeable on most adapters/ mounts), so if you absolutely need a Perfectly Straight Focal Plane and an Extremely robust and Reliable connection to the Camera, Screw Mount Lenses are usually the Way to go, which is also kind of the Reason, they even still exist and are still in such heavy use in Industrial Environments.
As also Stated in my above Post, Native C-Mount lenses are also usually available with much faster Apertures.
Or just go with native MFT Manual Prime Lenses, once the Mount adapter from Krontech is available, The MFT Mount System has some nice Lenses Too, but for the Chronos 1.4 you probably have more/ better Options with straight up C-Mount Machine Vision Glass.

Same problem here, but not solved yet. Anyone have a fix for that?
I have this adapter, (https://www.amazon.de/Fotodiox-Adapter-Clicked-Aperture-C-Mount/dp/B00VIVXL2E) btw.
EDIT: Nevermind, looked at the Post from clkdiv here again, and the Images on that amazon Page do show The Same Set screws on that seemingly same adapter i linked from the Fotodiox Page directly, so i guess the image just doesnt show that correctly. Or they do have them on some Versions/ Revisions of that Adapter and not on others, as the Locking Pin "Button" also seems to be different, but otherwise the Images are the Same? Might also be some kind of Photoshop involved here?
Guess the only one is the Italian one then, but given that apparently EVERY other C-Mount to Canon Mount Adapter has those Set Screws on them, i am really not sure anymore, if that one does have them or not, and would absolutely request detailed Images from the Seller before ordering!
