I would buy the Fotasy Copper from your link. CF of 36 in. on a 100 mm
lens is pretty good; then I'd use an achromatic C-U lens for closer.
The Oly iS/L Lens A-Macro H.Q. Converter f=40cm would screw right in.
Thanks for commenting. It does have the adjustment screws and the
price is right. The issue is the lens itself---"If you need an
adapter ring to use this lens, it is recommended to use an adapter
with a centerline adjustment function."

Good observation on the Oly iS/L converter--not one I have. I have a
fair number of achromatic CU diopters but not that one. Your stable
Your post prompted me to do a quick calculation. With the CF of 0.9m,
would have a max mag of about 1:7. 30mm of extension would get quite
close to 1:2. My worry with the CU diopter is it might pop the
bubbles. My experience has been the CU diopter seems to really smooth
out bokeh, at least in general. Fotodiox seems to have a helicoid
macro adapter, but it is half the cost of the lens. Also, not sure it
is "adjustable", but it does have screws. The lens seems to be out of
stock for at least a month. It is pretty soft wide with very "bad"
corners open but then that is not the really the point.

I have the Fotodiox adapter for Sony E and the macro extension is more
than most. Probably my most used adapter. The Vello seems almost
identical and I often wonder if made by the same factory. I have never
had an issue with the scales not being on top.

These seems to have the adjustment capability. They just don't have a
helicoid, which I consider essential. Most of my alt lens photos are not
taken at infinity.
