So I've been lens hunting lately...quite a bit actually.  I own a ton of Sony native glass and since I'm a big believer in adapting glass to my Sony mirrorless system, I've been adding Canon L glass to my cupboard so to speak.

I picked up the Canon 200mm f/2.8 about a month ago and really loved it from the start.  For a 200mm it's light, easy to use, performs very well, and cranks out some KILLER shots.  I was in love.

I then found out about the Holy Grail lens.  The big boy.  The one we've nicknamed as "Jaws" because it's a great big white shark of a lens.  I already had the Canon 200mm f/2.8, so spending the money on "Jaws" was difficult to justify.  Do I spend thousands of dollars just to get that tiny difference between f/1.8 and f/2.8?

I searched online and couldn't find any videos that showed the difference between the two lenses. I looked at countless pictures that the two lenses rendered looking for the subtle differences between the two.  I still was a little hesitant.

But then I put it out to my followers on my Facebook Group and I asked my Canon shooters what their thoughts were....well, they told me the Holy Grails lens (F/1.8) was indeed a legendary lens.

So I got it.  I went up to San Francisco and did a shoot at the ruins of the Sutro Baths.  I wanted to put out the information to the photography world that I couldn't find.  I wanted to show them what I was searching for...and had to spend a LOT of money to find out.  Was the difference in the background rendering between f/1.8 and f/2.8 really that much?  Did it really make a difference int the shots?

Hell Yeah it did!  If I'd never used the f/1.8 I'd still be madly in love with the performance of the f/2.8.  But once you see the comparison between the two, it's pretty obvious that f/1.8 really does make a difference compared to f/2.8.  Especially when you combine the compression factor of a 200mm lens.

I've included a video of my experience and images below.  I hope it helps you all out there!
