A $25,000 zoom lens in a PL mount that only covers super 35. Just what the average NFS reader is looking for.
I would say "focusing" implies you're moving a lens element to achieve focus, not just keeping subjects within a zone of acceptable focus. I suppose the "focus" in the title could be a noun here, but that's not the impression I got.
None of these focusing methods involve focusing.
Dude, stop with the "cheap LEDs" shit. You will undoubtedly regret cheap LEDs. Get a $3 incandescent bulb and you won't have to worry about color.
Could be shaded bright sunlight, too. Like at noon when the sun is over the building and not shining directly into the window, and all the indoor light is bounce from the atmosphere.
Why would you ever use LEDs if you're trying to save money? Incandescent or halogen lamps are fine and you don't have to worry about color rendition.
