I wanted to make some video shots of MIG welding for a tool making video but I had never done this before and I didn't want to destroy my camera. I do not know how easy it is to burn the sensor.
I thought that for safety sake I needed to hold a welding helmet filter in front of the lens. I did not not want to spend much time on this and to mount a typical rectangular filter looked to be too much work, but then I wondered about the circular lenses from gas welding goggles. I quickly discovered that two filters gave about the same light attenuation as a typical electric welding filter. My luck was running well and got even better when I discovered that the round filters were a perfect fit into a 52mm camera UV filter that I had from my film photography days. My camera lens has a 67 mm thread so I made a stack of reduction rings from 67 mm down to 52 mm, installed the UV filter followed by the two welding filters also followed by a welding UV filter.
It worked, the videos came out nicely and the camera still functions.

Filters stacked. Some plasticine holds it altogether.
Fitted to the camera.
I expect that there are several people on this forum who have videoed welding and I would love to hear how others have done it. Videos on the net seem to vary a lot regarding quality and brightness so I suspect that some people just use a naked camera ????????
Nice work Tony.I'm a novice but I was wondering if a clear lens protector could have been used to hold the light protective ones in the cavity in place instead of all that work?
I remember seeing, a few years back, a pro photographer who had his lens signed by a soccer/football player (out of the blue) with a permanent marker thus destroying his $100 000 lens. A $30 clear protector would have saved all that cost.
I don't know if the intensity of the arc flash contributes to long term damage of the electronics of a digital camera but my old Nikon 35 mm if I didn't use several stages of filtering the film would be so over exposed and any aperture setting the developer would not even print the frames for me.
How does a permanent marker destroy a camera lens?
