footage WEIRD SPOTS ON MY FOOTAGE

[AZON]

Hi Guys, First post ever in a forum of any kind, so here I go. I bought the Sony A7 iii about 2 months ago, I have shot only a couple of times, and i had found that it is a great camera, I really love it , but when I went to my editing room , after  a long while I had notice that my footage have some kind of weird spots, I didn't notice at  the moment because I was shooting through the view finder , So yeah i have this spots in my footage and I don't know, if it is the sensor or lens that I should clean it , or some kind of malfunction in the lens or sensor , so if you please guys can you help me , I will really appreciate it . I am going to attach a screenshot so you guys  can see what I'm talking about. One of the pictures is just the normal footage and the other one it is just a little more with contrast so you can see what I am talking about. I need also to clarify that I have never touch or clean any think inside the camera like the sensor.

 

Thanks for any help or recommendation you can give me.

Gunk on the sensor. Take a CLOSE look with a flashlight held at an angle. The smallest of specs can have huge repercussions.

Brother had the same ringworm artifacts and other divots on his camera. I get them on my sensor no matter how careful I am cleaning the lens and housing cavity swapping lenses. Get a wet clean kit and have at it. Brother was going to take it in to be done for $40 but convinced him the kit's the same amount and there'll be a time on a shoot it needs to be cleaned NOW and not two days later. Bulb blowing and in camera sensor cleaning almost never clean it completely.

I now ensure that after fitting a lens to the body, the first thing I do is run the cleaning programme and have found it does remove most of the dust / gunk from the sensor but usually there are always a couple of marks that can easily be removed in editing - alas, mirrorless sensors always appear more prone to DSLR  cameras.
