Is it better to use a better lens or a camera video microphone to prevent hissing AF lens sounds heard in a recorded video?

The reason "lens noise" is recorded when auto-focusing is because the internal mic is not isolated from the camera body. The motors moving the lens to auto-focus vibrate and cause that noise. The vibration picked up by the mic and recorded.

The resolution is to decouple the mic element from the touching any hard surface of the camera. This can be done with an external mic - wired or wireless. External mics can either be connected to the camera (usually with a 3.5mm or XLR connector) or an external field audio recorder with built-in or external mics.

It depends what I'm recording. For interviews, I use a wireless lavalier mic (Sennheiser G3) connected directly to the camera + an field audio recorder (Zoom H5) positioned closer to the subject, out of the video frame, as a backup.

Rarely is the internally captured audio used for the final video. The internally recorded audio is typically used to sync the externally captured audio - then muted.

The best thing to do is use a separate audio recorder 

and sync the audio with the video when editing.  

Tascam offers good digital recorders starting at about $100.    

If you're so scared for your life that you need mask, gloves, face shield, vaccine, etc., then you're "protected" from me, right?

If you're "protected" from me, then I don't need any of those things 'cuz you're already "protected"

Just aksin'... because u'r already protected, then why do u force those things on me (if u'r already protected)

I'm gonna just be carrying ma gunz and if police approach me to chip me (via vaccines), then shots will be fired; mark ma wordz

Especially at checkpoints on highways near entrances of the city like it is already in Ireland... Dublin = dumber than any civilized city...

du u love freedom?

Spanish flu vaccine killed all them victims in the Spanish flu era; and that's a fact

5G will kill COVID vaccinated

COVID vaccine contains chip; chipped people are influenced to receive World Passport grey plastic card with no name on it (when they stretch their hands to get it, gov't clerk secretly presses button to administer the unforgivable green 666 by isotope rays according to saint Vyacheslav Krasheninnikov).

influenced by Super Computers (mind you)

evil flying antichrist will release prisoners and insane asylum folks to help him "mark" people; in the cities it will be voluntary first day; next day they do it at gun point as they do in Africa already (chipping kids via vaccines at gunpoint in Malawi)

who said that I carry a cellphone on me; 'cuz I don't

someone wants to shoot those who refuse to obey these stupid rules, that's what Project Zyphr is about; gov't turns off electricity and sends a drone with scopolamine at 4am to your house; once gassed, u come out to 'em urself; they take u 2 underground re-education camp to torture u 4 adrenochrome; the remaining people will be chipped when they sign up for food in closed stores; project pogo was to gather info on who is to be annihilated during project zyphr

Any lens can produce both mechanical and electronic noise - use an external mic if you must, but a dedicated recorder like a Zoom or Tascam is better.
