From what I've read (and I have no reason to disagree) the 75mm F1.8 is one of the sharpest lenses out there, from any system. As you would expect, along with its high image quality comes a very sharp price, about $900.

it must be bought separately for $75. I think this is a terrible marketing
plan for a lens that costs $1000 USD. (I bought an equivalent hood for $25 on eBay.)
As nice a lens as this is, I haven't used it much. In fact, when I filter my metadata in Lightroom I see that since buying the 75mm in October 2012 I have kept only 600 images. With 5,000 images in my Lightroom catalog kept since that date, this means 12% of my pictures were taken with this lens. This calculation got me curious as to when and under what conditions I've used it.
My first outing with the 75mm was during the month of purchase, October 2012. I used it at a family wedding, and I recall buying the lens in anticipation of this event. I wanted to avoid a flash so the fast aperture was ideal. And the effective focal length of 150mm allowed me to be far enough away from the action to stay clear of the professional wedding photographer. Essentially all the images were taken at F1.8 or F2. To be truthful, for me, a fast zoom would have been more fun because at a wedding it is so hard to move forward/backward to frame your pictures. A zoom would have solved that problem. I'd like to try it again with the Panasonic 35-100mm F2.8. I would have lost a stop of light but would have gained flexibility in composing images. (On the other hand, the 35-100 lens had yet been available.)
Below are a few shots from the wedding and rehearsal dinner. The camera was the Olympus E-M5.

Camera Settings for the 75mm:
I found with all of these situations that Aperture Priority and AutoISO work fine for me. With the indoor people shots, I would set the aperture at typically F2 and the camera would increase ISO as high as necessary to maintain a safe shutter speed of 1/160sec. This seemed like a reasonable shutter speed for me; however, if I were to have wanted a slower or faster speed I would have turned the mode dial to Manual Mode and set both speed and aperture, while still maintaining AutoISO.
