About the same as my settings, and I agree don't meter off the sun but over to one side. I always try different shutter speeds and apertures but ISO always stays at 100.
Here's one at ISO200 a couple of days ago, shutter speed 1/350 with the Pentax M50mm f1.7. Not a great scene for it but not too bad for a sudden urban sunset grab without a chance to go to a better spot. Metered by looking at it and guessing at shutter speed...I very rarely use auto metering, I look at the overall conditions and decide what settings I want, usually it works out pretty well...I was already set to ISO200 and just didn't bother to change it, 200 gives me no more noise than 100 so I rolled with it. Hand held sitting in my Jeep with it idling. Saw this in the mirror and decided to turn around and get a shot of it.
