I should give up on explaining!

There's a reason why lens choices are made. Try it yourself. Shoot a two shot OTS on an 18, a 50, and a 100 - all at say T/F11

Lay image stills from each prime shot on top of each other in say photoshop and scale them to match up. Then turn layers on an off. You will see that a crop of an 18 looks very different then a 100. Especially pay attention to Z spatial compression. With the 100 the subjects will appear closer to each other, and on a 18 they will appear much further away.

"With it you can shoot one shot and use it for Wide, Medium and Close Up and present it as 3 different shots..."

no No NO!
This is the exact mentality many had to deal and fight with from less knowledgable TV producer types and technically challenged inexperienced directors when 4K cameras first started becoming accessible 10 years ago.

Your similar statement at this date reveals you are an enthusiast at best. Please consider taking one cinematography class, or actually shoot something with a couple primes of different focal points, then re-evaluate that logic.

RED demanded to buy back (and did) the last RED camera he had.

And seriously harsh on the photography.
The guy shot all that footage in one day;
he had only 24 hours with Jarred's personal white helium weapon.

"So. Last week I met this guy Jonny Mass on Facebook. He is 19 years old. He sent me some incredible things he has been shooting with his Scarlet-W. I really liked him. So much Passion. In it for all the right reasons. So I sent him my personal Helium8K for 24 hours this week. Just a few days ago. Not sure how he did it.. but somehow... he managed to get an incredible crew together, some talent, some locations and he shot a little thing. Shot in a day and edited, colored and finished it in 8K a day later." -Jarred Land (facebook)

haha, totally!

Touchscreen not needed for most, myself included.
In fact, I do not like or use RED monitors.

Fool control packs all the tools needed in your pocket.

I do agree about the memory.
Sure, I don't enjoy spending well over 2K per red colored HS card.
But I know my shots are safe, secure, and I can treat it like its in the can.

Another important point to appreciate: compression
TeodoRED records with heavier compression ratios, and limits higher FRs.
Which is like buying a 4K DCI monitor, and giving it a 720p feed.

FYI, you can do the same thing with any laptop.
Recording via a Gig-E network cable to a mac/pc has been around for over a year.

RED specifically sells a 9 foot cable for this:

If your target is web only at speed,
and you plan to downscale or window down to 1080,
recording over Gig-E may be useful - perhaps for long interviews.

For those interested in learning about lighting and exposure,
I highly recommend Dave and Maria Viera's book revision:

Lighting for Film and Digital Cinematography 2nd Edition
by Dave Viera (Author), Maria Viera (Author)
https://www.amazon.com/gp/product/0534264980/
(I pretty much threw away most of my other lighting books after reading this)

Another handy book to help grasp setups:
