Help with Zeiss 24mm!

Thanks for your reply! I checked the meta data on my photos and from what I can see I like shooting around the 20-28mm and 16mm-(+UWA adapter = does this equal a 12mm?). There are very few that range between 30-55mm.

I posted some photos above of some shots i took around the 20-28mm range. Do you think I would notice remarkably sharper quality using the 24mm?

The 16mm(+UWA) was borrowed, so ideally I would like to get a 12mm Zeiss for wide shots.

If I could get one (for the time being) would you recommend the 24mm or waiting for the 12mm?
