Chronos User Discussion / Re: High-quality C-mount lenses?
« Last post by Nikon1 on Today at 06:15:18 AM »
I read a bit through your posts on the Forum and looked at your YT and it seems you have a 1.4 and you are doing stuff like Capturing Lightning and such.
 .
 While for the 2.1 i cant really reccomend to go with C-Mount Lenses (at least for your general Purpose Lenses, Macro might make sense with an C-Mount Lens on the 2.1), its completely different for the 1.4, as its sensor is a lot smaller. So for the 1.4 you will find plenty of options.
 .
 I personally own and use a lot of C-Mount Lenses, mainly really old Vintage Schneider-Kreuznach Cine-Lenses for Super16mm Film Cameras, which can produce Very nice Images, but they are certainly not for everyone, as they can be pretty funky at times, and dont deliver the modern look you would expect from modern optics. If you are into very organic and Cinematic image Style, take a look at ebay, you can still find plenty of those everywhere (some became rather rare lately).
 I also own a bunch of newer C-Mount Lenses, and the best of the Modern C-Mount Lenses i myself came across so far are Kowa Brand Lenses. Really Sharp and High contrast, just nice Images they produce.
 .
 As a Place to look for modern Lenses i can Highly reccomend Stemmer-Imaging, they are a big Reseller (or whatever one would call that in English, not a native speaker...) of Machine Vision Hardware and Optics and Carry about everything you would ever need in terms of C-Mount Optics as a professional User, from Macro to Telecentric Lenses, and a lot of other very special glass.

 .
 First link is just directly to Prime Lenses for General Purpose Imaging, second one has allready set two filters for c-Mount and 2/3" Sensor size, what you would want for the 1.4.
 I am not quite Sure, what you define as wide, fast and sharp, but anything beyond 2MP resolution Rating should be more than sharp enough for the 1.4, if you want to make sure, go with the 5MP Rated Lenses, but those are usually quite a bit more expensive. Select Focal Lenght to your Liking.
 Also make sure, to check if the Lenses will work with an C- to CS-Mount adapter. My Kowa LM8HC Lens wont. Rear element is to Long to fit into the C- to CS- Spacer. Can still be used (wont make too much sense, as i have a 2.1 and the Lens is only 1" Sensor size, so it wont cover the whole Image, allready checked that...), but needs a custom adapter, so check bevore buying, if you buy such lenses only for use on the Chronos.
 .
 Another Lens i can highly reccomend in terms of Wide C-Mounts with modern Image Quality is the Azure 6,5mm 1.4 Lens, which i also own. Covers 1" very well (perfect for my Nikon1 J5). Havent seen that one offered at Stemmer Imaging however, only place to get it seems to be amazon, where i bought mine. Also Crazy sharp lens, can send you some Sample images if you like, send me an PM if you want.

 .
 Watch out however, the Azure 6,5mm also has a Rear element which does not fit into the Standard Cs- / C-Mount Spacer.
 .
 Other Lenses usually dont share that problem, but those two are pretty extreme, super wide and super Fast.

Chronos User Discussion / High-quality C-mount lenses?
« Last post by 1022mm on May 09, 2021, 04:48:28 PM »
Per my last thread, I'm struggling with the C-to-EF mount adapter stability.   I'm not seeing any better C-to-EF adapters available than the one I already have, and I'm at the point of buying a rail system to support and secure the lens.   Rather than deal with all of that, I'm now curious about just going for a native C-mount lens.  When I look at those, however, it appears they are tailored mainly for CCTV camera applications and not photography/cinematography.   I'm willing to spend the bucks on a high quality (sharp and fast) wide-angle C mount if one exists.   Is anyone using such a lens?  Thanks again!

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.

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.

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:

 This Drawing shows the Flange Focal Distance of the Chronos Camera body. To determine the correct Adapter Height of an Adapter for any given Mount, use the Difference between the wanted total Flange Focal Distance ( see https://en.wikipedia.org/wiki/Flange_focal_distance for an List of comonly used Lens mounts and their Flange Focal distances ) and the Dimensions in the Drawing.

Chronos User Discussion / Lens Mount for Chronos camera
« Last post by SergeyKashin on May 05, 2021, 07:48:47 AM »
Hello everyone, I found a factory that makes adapters for the red camera, made them a request to make an adapter for our camera, they agreed on the condition that there will be a batch of 100 pieces in total, they can make for EOS-Chronos, M3/4-Chronos, AI-Chronos.
One of these days, they will redo the 3d model of red for chronos, all the information that will appear will be updated here. They can orient themselves on the price as soon as they make a 3D model (the more they do, the lower the price)

Also tell me what is your distance from the camera body to the adapter (example below in the photo) ?
Is this distance the same for all lenses? (which are given above)


Write messages below example:
