Thanks much but you never did mention the cost of OM tilt/shift adapter.
Or maybe they did it for free for the experience?
Some things I didn't understand:
1) What is the "internal release mechanism" and why does it
have anything to do with infinity focus?
2) How does the teflon protector work? Is it a plug that fits
into the screw hole covering the screw head?
3) I don't understand panos by tilting... or do you mean panos
that also incorporate a tilt
4) I'm not sure I understand the 55mm not tilting on the nodal
axis (point?). Are you saying that taking a pano with the
55mm and also using tilt requires elaborate reframing, etc?
Thanks,
Chuck Norcutt
