Cameras and How To Film Watchmaking
Вставка
- Опубліковано 12 жов 2023
- I decided to do UA-cam from the very beginning of my watchmaking journey because I thought you guys might find that interesting. But it also made my life a whole lot harder because I had to learn how to film watchmaking at same time as learning how to do watchmaking.
In this video I share some of the most important considerations in selecting filming gear, and show you my filming setup.
I don't have the lighting settings quite right for the B-Cam - this is a work in progress. The problem is the light from the microscope ring light reflects straight off the movement & holder into the lens. So if anyone has suggestions about that, please chime in in the comments.

Hi! Thanks for a very interesting video! One thing I can’t get my head around though, do you capture all video sources the the hard drive simultaneously? With a couple of Elgatos. Or du you record to the cameras SD card?
Thanks for Watching - I record to the camera's SD cards - this is not an option for the Microscope, because I use the audio to sync up the video - the microscope has no audio in, so I use the Mac mini with the Elgato, and a lav mic plugged into the mic in port on the Mac mini. Then on the other 2 cameras, I just record to the SD Cards. I think this is the best way because it puts the least stress on the cameras - get them to stream and they will run hotter - we had a 39 degree celsius day last week, no way the ZV-E10 would cope. Also there are limitations on what res the cameras can stream. So I find the simpler things are the better.
Thanks! Interesting, I've read that recording to SD card is more heat producing than just live streaming, hence compression and writing. But I could well be wrong!@@watchout9213
This is exactly the question I had. I find it a pain to unscrew my camera from the mount just to retrieve the SD card and was thinking an HDMI combiner with split screen would be better. But I think you need a powerful computer to handle the video capture.
Hey Stephen, great video! Some questions/comments for you since I am building a VERY similar setup. Hope you don’t mind, it’s a bit long 😅
Is the A6700 giving you any overheating issues? I have a ZV-E10 and I love it, but want to go to a 2 cam + microscope setup as well, so I’m thinking of picking one up. However, all the video reviews online bring up the fact they couldn’t get more than about 45 minutes of 4k filming before overheat messages and camera shutdown, curious if you’ve experienced this too. Thinking maybe just going budget and getting 2nd ZV-E10 since they’ll shoot for hours no prob, or maybe going for a used FX30.
Also, love the Sigma art macro series but I feel like autofocus is truly not needed for this, and in fact often just gets in the way. When you said you almost went with a full manual lens, was it by chance one of the Laowa ones? I grabbed the 65mm and it’s INCREDIBLE. If you do still photos with watches, the 2x magnification is absolutely worth it, incredible dial shots.
Next, when it comes to the microscope, are you having any difficulty with getting the trinocular port and eyepieces to parfocal? I have the same exact scope, and the camera port and eyepieces will not stay focused on the same point if I mess with zoom knob. The eyepieces work properly, but I always have to refocus the camera adapter ring after zooming.
Oh and the lighting, that’s my next area of focus as well, so curious to see what you do 😉. You seen the Zhiyun Molus G60? It’s $250 or so but comes with seems very flexible and it’s a great size.
No worries, it's great to help one another learn. No, I haven't had any issues with the A6700 overheating, but I haven't really used it much, and it hasn't been very hot in terms of weather. What I saw was that it was people using high frame rates for extended time that have problems. The FX30 was my dream camera before the A6700 came out, but the main prob with the FX30 is lack of viewfinder, which isn't an issue for watchmaking, but can be a problem for out and about. I took the ZV-E10 out to see what it was like, and it was a real pain not having a viewfinder - couldn't see a thing on the screen in full sunlight.
Yes, the Laowa 65mm is the one I was looking at, but the Sigma was not a lot more money, and as I said, gives me 105mm equivalent. My understanding is that the 2 x magnification tells you how close you can get the lens to the subject and have it still focus. So 2 x means that at the minimum focal distance, the subject will appear as 2 x size. For the reasons I mentioned in my video, this is useless for watchmaking, because you need to have the lens far enough away that it doesn't get in the way. A 65mm lens is always a 65mm lens. That being said, if the Laowa is working for you, then great! And I might still get one for my b-cam. I currently only own 2 lenses, as I sold all my Nikon and Fujifilm gear to fund the A6700, so my plan is to use the Sigma lens as a long out and about lens. I can't see any reason why it can't do this, even though it is a Macro lens.
Microscope - no, I haven't had any problems with matching the focus up. Sometimes I might have to make minor adjustments on the camera focus, but usually it is pretty good. I think it will depend on the c-mount adapter you are using. I'm using this one here: www.aliexpress.us/item/3256801587206955.html?spm=a2g0o.order_list.order_list_main.108.22021802Yj9fBs&gatewayAdapt=glo2usa4itemAdapt
The 0.35 x zoom one.
Today I ordered a couple of lights from Amazon, this little one to replace the dinky vlogger ring light: www.amazon.com.au/gp/product/B06XDFGDCX/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
And this larger one, which I'm not sure just yet what I will do with. The Yongnuo YN300-III, www.amazon.com.au/gp/product/B00VFT94X4/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
I haven't seen the G60. The Colbor CL60 looks similar, but a little cheaper.
Wish me luck!
@@watchout9213thanks for the great answers! It’s good to hear you haven’t had any issues with overheating on the A6700, maybe I’ll have to rethink one. The viewfinder is definitely a nice feature, ditto on weather sealing for a6700 if you want to shoot outdoors. Makes me keep debating what I want heh.
The Laowa is an interesting lens when it comes to the magnification. If you want the full 2x then yeah, you gotta get very close. You can still get over 1x magnification at very workable distances IMO though, so worth trying if you get a chance. It’s a 97.5mm on an APS-C camera, so vs a 105mm should be pretty minor IMO - but like you said, whatever gets you the results you like! And I agree, that Sigma should be amazing out and about.
Darn, that’s the same microscope camera adapter I have! .35x and all. Frustrating. Oh well, worth an ask.
Those lights look like they should do the trick, hopefully you’ll let us know how they work for you. Wishing you lots of luck, and thanks again for taking the time to answer everything! Cheers! 🍻
No worries - I believe the Loawa 65mm lens is an APS-C lens, so its 65mm should be 65mm. But, you've got one and I don't so if it works, great! OH, where did you buy it from?
I think I got all of this wrong - the lens focal length is the lens focal length is the lens focal length, regardless as to what sensor it is designed for. That just tells you how much of an area it will fill. So the 65mm Laowa would be 97.5mm due to the 1.5x crop factor on an APS-C camera. The fact that the lens is an APS-C lens is irrelevant, 1.5x crop factor still applies. Someone tell me if I am wrong or right, please.
@@watchout9213 😊Absolutely right! When using an APS-C camera the crop factor always applies, no matter if it's an APS-C lens or not, because like you said the focal length is the focal length no matter what sensor it was designed for. It's a bit of a weird thing to wrap your head around at first for sure! Oh and I got the Loawa from eBay, found it for a great deal new.
