Will all C-Mount lenses cover Lumix GX85 sensor? Does it work with a C-Mount to Micro Four Thirds adapter?

Yes it will and it looks lovely. You get a slight bit a vignetting in 4K, but the more you stop it down, the darker the corners get.

In fact, just a few posts above yours, someone shared this video all shot with 25mm cmount:

No. Check before buying.

So yes or no? :) How to check before buying a used one in the internet? Are there different C-Mount lenses with a different angle of view? If I understand it correctly, it will almost cover the sensor with 25mm and above?

There is no absolute image circle size for a C-mount, nor is there an absolute image circle size for the various focal lengths with a C-mount.

 

Furthermore, one can use an adapter to mount APS-C and full frame lenses to C-mount cameras.

 

You just have to determine the image circle of each lens on an individual basis.

This is true. Rule of thumb is: 90% of c-mount lenses are designed for 2/3" image circles (i.e. half of MFT, equivalent to 4:3 16mm film), 15% are designed for 1/3" image circles (Super 8 equivalent) or smaller, 4% are designed for 1" (or Super 16), 1% is designed for MFT or bigger image circles.

Might want to check the math and add the percentages.

 

At any rate, there were tons of C-mount lenses made for larger videcons/plumbicons, so, not the above percentages are a "rule of thumb."

Hey,

I've been lurking for a while now, and now it's time to post something. I have a GX80 for a few months now. Last week I found the following video about a DIY windbreaker for the built in MIC.
 



Now I thought that I could design something similar that could be 3D printed. So I did tonight. I still need to find some fabric to test it, but if it works I'll share the files.

Just linking to the post I made in the "shooting" forum of a 9-month documentary project I just completed with 2 GX80.  The shooting details, etc. are in that post.  Thanks to everyone who freely share information on this site as I probably wouldn't have attempted something like this without EOSHD as a resource!

@sgreszcz, nice video and great effort. I think your audience must be very happy with your documentary.

One other thing, your mididoc about your grandpa was very beautifully done! In your BTS you write, you´ve been

using the EP5, but your BTS video shows the LX100 and the GX7, great cameras too of course. Just saying :)

Thanks @PannySVHS!  The interview with my Grandpa was the first edited video that I did and when I shot it, I did use two EP-5 (which I loved at the time due to the tilting EVF-4).  However, I found out about the Rode Reel competition and realised I needed to do a behind the scenes and by then had already sold the Olympus cameras for the Pannys so needed some creative B-roll for the BTS.  It takes a sharp eye and a camera nerd from this forum to pick up the continuity errors ;)

I did a longer 10-minute doc on my Grandpa's life which screened at his 100th birthday in front of 200 people, and unfortunately his funeral at 101 this past spring in front of about the same amount of people.  I'm also working on a doc of my brother who is preparing for the 2018 Olympics in Skeleton.  Still need to do the interview though, although I'm a bit scared to throw him off his game by going too deep with questions and his 10-year struggle!  Maybe a retrospective doc instead...

Loved the LX100 (wish the colour was better, would buy a LX200 in a heartbeat with better IBIS). Liked the tilt-EVF on the GX7.  Love the GX80, but wish it had a mic-in and a better EVF.  Going to sell one of them now (and some lenses) for the GH5.

I don't think I'll ever get to the aesthetic quality of the images that I see from people on this forum, but I'm going to do my best to continue to find interesting stories in my community to document.  Thanks for the feedback and for all that I've learned from people who post on EOSHD!

The doc on your grandpa was very beautiful and very well done. Sorry for your loss. I was hoping your grandpa would live to be a 113 like his aunt. It is really great

to have a beautiful documentary like this of a loved one. Very well done!

Yeah, we camera lovers have a sharp eye and a soft heart for cameras:) LX200 with mic in and a mechanical focus ring and IBIS and pixel perfect HD up to 60fps with

at least 100mbit would be an instant buy for me:)

Did my first attempt to create a wedding movie since my cousin asked me to do so. Technically speaking, the thing has many flaws: no tripod, crappy in-camera mic of the GX80, .. you name it. Also i was a bit intimidated since the official wedding photographer told me not to get in his way, which is kind of understandable. In the end, the compact form factor of the GX80 really made it easy to wander arround and sneak some shots and i was suprised about the quality of the standard 45-200m zoom which I never used before.

However, it becomes more and more apparent to me that I need a camera with mic-in. Since I am happy with my GX80 the G85 would be the logical step, but the GH5 looks also amazing...

Not sure how much ambient schtuff you'd want to record at some venue like a wedding, it's mostly picking up what people are saying and how they're reacting (bringing some correlation to what you're seeing, actually isolating them from the mumbling crowd) rather than ambient sound, no? But yeah, shure, it's a directional mic by all means. I'd call shotgun on it. Of course it isn't a cheapy, and you could just get the G80 and even a simple mic as the RØDE VideoMicro would make a big difference compared to the GX80's own built-in mic and indeed no syncing workflow required if you would go external recording...
