Is there any information online pointing out that the RX1 lens has a floating element group?

This is great info and I will be using the macro ring for manual focus for types of shots where I need the camera to remember the previous distance.

It's worth mentioning that the 'fine tuning' you referred on your first post does not get saved when turning off the camera. Basically the camera defaults to 'infinity' but the macro ring is set to the correct distance with infinity as reference.


Yes, you are correct that this is how focusing works for a non-broken RX1, but I was referring to my (then) broken RX1, which worked as I described. Now that it's repaired itself, however, it works as you've described above.

One other tip: I wrapped a pair of heavy-duty zip ties around the macro ring to serve as a poor-man's lens tab, because focusing precisely at distances close to infinity requires a delicate hand, especially when I have the Bronica bellows hood attached, and using a finger on each side of the lens helps. In my case, the zip ties will also easily slip on-and-off as needed:

Yes, Fred, there is ... see page five of this .pdf doc

But as far as I've been able to tell, focusing via the macro ring doesn't degrade the image quality in any way that I can see.

Thanks for the link. I suspected it had a floating element group based on the great performance at infinity and closer distances. It's surprising that the floating element feature is not detailed in the lens specification anywhere on Sony's page.
The "poor-man's lens tab" is a great idea since the macro ring is very thin and may be difficult to operate for same folks.
The Sonnar 35/2 is definitely one of my favorite lenses.
