Today we tilt/shift our focus to the lens… how appropriate! First DSLR lenses invaded the video space - now we commonly shoot video through still photo and smartphone lenses.
00:00 ** Panel Discussion - Picking Lenses **
15:47 What zoom lens would work best for zoom meetings using a Panasonic GH5 with a 98" tv as an LED wall? Would the Olympus M.Zuiko Digital ED 12-45mm f/4 PRO Lens cut it?
25:16 In still photography the # of iris flags are a factor, is this the case in video as well?
27:15 Is there anything that is optically special in the glass for the different size sensors or image formats?
29:21 Every lens is a compromise, be it price, weight, complexity, or favoring one virtue over another. What might the compromise of using one of the wide angle distortion correction lenses such as Laowa Zero-D line for video?
32:52 What focal length provides the most natural image?
34:02 Is it possible to have a very fast zoom lens, or does the extra glass necessarily slow them down?
37:03 When referring to aperture lenses that are f2.8 and lower, what makes them "fast." Are lens elements internally moving faster than an F4.0?
37:55 What visualization tools can be use to determine lens choice from the planning stages based on a blueprint or layout drawing of a venue?
40:45 Does having great tools like Topaz AI affect your choice of lens and/or ISO setting?
42:48 Thinking of buying some used lens (just to play with some looks) is there a "quick" way to test basic functionality? Use a chart I guess?
47:36 Do parfocal lenses exist for micro-four-thirds cameras or can be adapted?
50:24 I have had the experience of seeing the difference between a very high quality lens and a less expensive one, they both get sharp, but I can’t put my finger on what exactly is better that I am seeing, any thoughts?
51:50 How have tools like Unreal Engine changed the process of previsualization in video production?
