Been there, done that minus the leaking wellies...but there's a dedication to getting up at 1am for sunrise on Skye that a lot don't manage.
The dedication works all ways, all year. Like you, been there done that too. I would say though, on 2 occasions a couple of years ago, I ended up staying up for 37 and 42 hours respectively, that was dedication, if a bit daft. I won't go to that extreme again, I actually felt ill but getting out of bed for a shot doesn't bother me either, although, if I'm leaving home at 1am, I will stay up and sleep when I get home about midday.
Another trick during summer is to go for the sunset hours, stay through the dark hours, then get the sunrise. The middle of the day during summer usually doesn't appeal to me.
Chose you poison, get chased off Rannoch Moor by the cold, or get chased off by the midges. There's a rare sweet spot in the year where neither applies.
Got both those T-shirts too. Oddly enough, at 3am one morning, the midges were coming through the vents of my parked car, there was no escape. The low drone I could hear was midges outside the car, I couldn't see them as it was still dark. Only as it got light did I see thousands of them crawling along the bottom of the windscreen, inside the car. Oddly again, they weren't biting inside the car but outside was murder. I had to drive away, windows open, blower on full. I must admit, that was unpleasant. I was parked in that layby on Rannoch Moor, the first one on the right, just about opposite where the campervans park up, you'll know the one.
Cold is OK, don't mind that, I've never really felt it. I sense it's cold but it's not bothersome.
What's a 3rd of the way in?
Generally speaking, I put a single focus point on the bottom third line, on a rock or something that might be there. It's not perfect though and needs tweaking at the time but gives acceptable results.
I feel it could be better though, and why I'm considering trying stacking, when I get to know the Sigma (and 16-35) better.
I'm not sure on the 10x8 print thing, 1/3rd of the way in just seems logical for landscapes. I am seeing the flaws in it though.
I was out last night, just a wee jaunt, and opened up to f10. I worked at f11 one night last week with the new Sigma which was underwhelming, it seems much better at f10 with better front to back sharpness. I may try f9 next time, I think it could be an improvement again. It's a new lens, I need to use it to find it's sweetspots. No doubt, the 16-35L will need the same approach. My hope is that it is better than the 17-40, which it should be.
Medium format is appealing, I have no doubt about its improvement, even over FF. I also have a bit of a thing for Fuji, and they make some nice MF kit. Fuji may not be the best MF kit out there but the best of MF is out of reach for me. MF wouldn't really be much good for my other passion, wildlife as the lenses for that don't really exist (as far as I'm aware) but it's horses for courses, so if I ever did take the MF plunge, I'd also keep some of my Canon gear.
MF? Maybe one day. For now though, it is what it is and I have to work with what I have...... not that what I have is too shabby.
