I found all that "everything is in focus on a wideangle" trope rather... removed from reality. Especially for astro I've been dabbling in that for some time now). How come a tiniest rotation of the focus ring on my 24mm lens throws everything out of (usable) focus - say, the stars? I ditch the AF for this, of course, and rely on maximum mangification in Live View - and still...
It's also very easy to get misfocused shots with the Sigma 14mm f/2.8 that I have - even though it's wider AND slower. If something isn't melted into boken balls altogether that doesn't mean it's sharp, let alone usably sharp.
BTW I may be watching the Perseids this night as well. Depends on what the weather is going to be like, of course - if it's fine I may rush outta town and down south to the village where a bunch of astronomers I known are camping.
