Thanks for your comments David.
The most important comment you made, and this could be an interesting topic for this forum to discuss, is how much furniture to include in one shot. In the dinning shot, we wanted that angle and there wasn't enough space to back up. My concern was not to crop the table glass and to see the lamp feature. For the living room shot I don't consider it to be distorted.
The haze is provably from blending the images, even though I use flash and HDR, the sky had to be composited.
I did use nail paint to mark my basic stops in the adapter. For this architectural I'm always at f11. So basically I open up, magnified, focus and the close to f11.
How did I get to find out where was f11 in the first place? Well, I used two 24mm lenses, put the camera on a tripod with a mark diaphragm lens at f11 on "A" mode and watch the resulting shutter speed, then change the lens, close the diaphragm until I got the same shutter speed and that is supposed to be f11, marked with nail paint.
This is a great adapter and I totally recommend it. Is super well constructed.
