Question: Get a clear what of him?
Answer: A clear shot of him.
"what" replaces nouns. The phrase "a clear shot" is a noun phrase, made up of an article "a", an adjective "clear" and a noun "shot"; "shot" is a noun, a thing. It looks like the past tense verb "shot" (e.g. I shot him), but it's not a verb in sentence 1. We know this because it is modified by an article and an adjective.
2. Let me get a clear shoot of him. :(
"shoot" is a verb, a present tense verb. Sentence 2. is ungrammatical becuase, a verb cannot be modified by an article or an adjective:
a clear shoot :( (Article+Adjective+Verb) (Not OK)
a clear shot :D (Article+Adjective+Noun) (OK; big thumbs up!)
All the best,
