Thank you Jack , we had already two answers from Zen about the DP-170-N85 first version , that have been published on our board in France :
Sure thing, the DP-170-N85 works with the following lenses:
- Panasonic 7-14mm f/4 plus 30mm extension
- Panasonic 12-35mm f/2.8 plus 30mm extension
- Olympus M.Zuiko 12mm
- Olympus M.Zuiko 8mm f/1.8 PRO
- Olympus 9-18mm f/4-5.6 plus 30mm extension
Thank you for contacting us! Unfortunately, you cannot use the 12-40mm or the 12-50mm with the first version on the DP-170-N85. The reason is the the diameter of the lens is too large to pass through the Nauticam Mini Extension Rings. The DP-170-N85II actually has a larger inner diameter around the port base to allow the fatter lenses to pass through. The 12-50mm zoom gear is also too large in diameter to pass through the mini extension rings from Nauticam.
That's correct, there is no vignetting with the Olympus M.Zuiko 8mm PRO lens and the DP-170-N85, even in the raw files. The corners are what you can expect from a fisheye lens, still soft, but very manageable when shooting the right subject.
