Before I dive in....

1) I understand cameras are tools, it's not the camera's fault :)
2) I want to test but I don't have access to an Alexa LF
3) Over the short time I've been working, my clients don't actually care what camera I use (seriously don't) but my contemporaries can't stop talking about this stuff. 

What's the big deal and why is everyone talking about large-format? The sensor is only the size of 35mm film, right? That's not much bigger than super-35 sensors. Shouldn't the Alexa 65 be called "Large format"? And what about 120 "medium format" film? Isn't that like four times as large as the Alexa 65?

Here's where the testing comes in - couldn't you lens an Alexa Mini to look like an LF by using a different focal length?

I don't get it. But that's only from reading and seeing what people are doing with "Large Format" cameras. (would like to try/test one day to give my rant some more weight). I feel like a crazy person.

Thanks. Axel

This article explains it with some side-by-side comparisons.

Steve Yedlin did a test some years ago comparing different resolutions, formats and cameras. 

He compared, s35, FF and 65 formats. I encourage you to take a look at it:

If you go to his homepage you will see other tests he did comparing Film with digital cameras on Color Science.

Cheers,

Wow, eye-opening. The >1 hour presentation (part 2) is really worth your time!
