Hi folks,


There seems to be two main lens options for rectilinear ultra-wide (weitwinkel) angle (so no fisheye) in the micro four-thirds galaxy: Panasonic 7-14mm and Olympus 9-18mm.


Which one is best?


In case the answers are "it dependsish", I would look at the following scenario:

Camera = Olympus OM-D EM5.

Things that matter (for me):


-Image quality in general (I read on DPreview that the 7-14 Pana's cromatic aberrations were discarded by in-camera software on Pana cameras, but not on Oly ones, is that an issue underwater?)

-Good for Close Focus Wide Angle.

-Fast AF


thanks in advance for sharing your thoughts & experience :-)

See this article for your choices http://www.uwphotogr...thirds-cameras. Adobe Lightroom 4 has a "remove chromatic aberration" tool now. Its under lens correction.

I'm curious about the 9-18 vs 7-14 lenses.  Are there any informed opinions on which would be a better option?  I assume I would use one of these lenses behind a Zen 100 port.

(Primary) Nauticam 550D, Canon T2i, Canon 60mm macro, Canon 100mm IS, Tokina 10-17FE, Zen 100mm domeport, Nauticam 180deg viewfinder, Dual S&S YS-110a, SOLA 600 focus light, Dual AOI RGBlue video lights, GoPro Hero 2


(Backup) Olympus E-PM1, PT EP-06, Olympus 14-42 II, Olympus 60mm macro

Well, fwiw I have both lenses and prefer the 7-14.  It requires the 6" port so if packing space is critical that could be an issue, but overall I like the extra FOV and feel it is a bigger difference than it might seem just looking at numbers.  I also feel the lens is a bit sharper, but if so it is probably all but insignificant.  Sometimes I think the 7-14 is a a little weak in the corners, but am not sure if that is the lens or the port and it is a small thing.  Generally I am not using it for shots where corner sharpness is critical and if the corners are water or sand or dark it doesn't matter and corners can also be cropped easily.  The 9-18 works in the Nauticam 4" port.  I have not yest used the Zen 100mm.  I don't know if it matters to you, but the 9-18 also overlaps the FOV of the 12-50 quite a bit and both those lenses can be used in the same port.


The minimum focus distance on both is the same.  I am not that fond of either for CFWA; I think the 8mm is much better for that.


I like my 8mm fisheye better, but the 7-14 is a lens I am reluctant to leave behind and I typically only use the 9-18 as an above-water travel lens.  The extra FOV of 7mm is the big deal for me.  I am not sure, but I might use the 12mm Oly lens before the 9-18...I don't have the 12mm yet so I don't know how noticeable the extra sharpness and speed are underwater.
