  1. Hello, I am trying to understand how this phenomenon can occur, In the movie '' Good Time '' of the Safdie brothers, I have noticed several times that the highlights that flare restore the source, not by a glow but by drawing of it. In the case of the example number 1 we see that the text in the window is present as a flare but that, it does not make a ring / point in flare but a reproduction of lettering neons. In example 2 the flare corresponds to the bulb pattern of the carousel. Can someone explain to me if this effect is due to a phenomenon of the used optics, a lens filter effect, or post-production? I am French mother tongue I hope that I managed to make myself understood. I thank you in advance.
  2. Hey there. In my day job I regularly shoot from gimbal stabilizers and aerial rigs using dslr and mirrorless cameras and lenses. Given that I do not often have access to a wireless follow focus, I have to improvise and work with hyperfocal distances and such. The one piece of information that would be really usefull to me when planning shoots where we will be hiring in this sort of gear never seems to be available in any review or spec sheet. That is the distance beyond which the lens has infinite focus. I can usually take a rough guess with fixed primes, but with compact zooms it's a completely mixed bag. I often resort to google image searches and taking a guess based on the lens markings, but some newer lenses have no focus markings at all. For instance on an upcoming shoot using a Sony a7rii we are considering using a Ziess Vario-Tessar T* FE 24-70mm F4 ZA. The lens has no focus markings and I can find no spec sheet anywhere that tells me even approximately at what distance this lens achieves infinite focus. This information would be really useful to me. I know that by using hyperfocal distances I am to some extent negating this issue and always achieving the maximum possible field of sharp focus in any given situation, but it seems like this info should be available as a matter of principle. Does anybody know where this spec might be available for modern lenses? Thanks
