In Topic: DPreview of the New Olympus M.Zuiko 8mm and 7-14mm PRO Lenses

13 May 2015 - 02:16 PM

The Oly 8 mm fisheye is 28,3 mm longer than the Panasonic 8 mm fisheye offering everybody has used so far.


The new lens should operate satisfactory in the previous 4,33 mini dome port if you add a 30 mm mini extension ring I guess?


This is for the Nauticam system of UW housings of course.

In Topic: Nauticam CMC-1

The CMC works with the 60mm Macro does it? I have the SMC lens (sorry to be a little off topic)and have found it hard to use, mainly from being still enough. Phil is there any difference between the two lenses when used with the 60mm?


The CMC gives you 2x on the Oly 60 mm. The SMC is only 1.6x or something. I found out the hard way after noticing little differen in the magnification between the SMC and the ReefNet +5 (1.7x) on my Oly 60 mm.

If we assume that the integrated hood is maximized for both lenses, the lenght difference is 105,8 mm - 83,1 mm = 22,7 mm. So it seems that the 20 mm extension previously shown in Adam Taylors picture above should be sufficient. A 22,7 mm extension is probably unlikely?!

Final spec for the new Olympus lenses:




  • M.ZUIKO DIGITAL ED 7-14mm F2.8 PRO
    – Will be released in Japan in late June 2015
    – Dust-proof drop-proof (11 places sealing)
    – Total length: 105.8mm
    – Maximum diameter: 78.9mm
    – Weight: 534g
  • M.ZUIKO DIGITAL ED 8mm F1.8 Fisheye PRO
    – Maximum magnification 0.2 times
    – Total length: 80mm
    – Maximum diameter: 62mm
    – Weight: 315g


As previously speculated the diameter of new Olympus 7-14 f2.8 lens is to large to fit inside the Nauticam N85 port system.

Finally there seems to be an official Olympus announcement of both the 7-14 f2.8 and 8 mm fisheye f1.8 early next week.
