The Precision Olympus PEN 4-inch 8mm Fisheye dome is designed specially for use with the Panasonic Lumix G Fisheye 8mm/ 3.5 lens, on the Olympus E-PL1, E-PL2, E-PL3, E-PL5, E-PL7 or E-PM1 housings.
The dome is tuned to assure edge-to-edge image sharpness, based on the lens nodal point. Made of optical-quality acrylic, this dome provides a wide angle-of-view to maximize the capability of your 8mm fisheye.
Installing this on your Olympus PT-EP01 or PT-EP03 housing is a snap!
The Panasonic 8mm fisheye lens gives you the widest possible view on your Olympus E-PL1 , E-PL2, E-PL3, E-PL5, E-PL7 or E-PM1 camera, and is the best lens to use for wide-angle underwater photography.
The Precision dome is very high quality and is made with a perfectly designed acrylic dome to offer high quality results. However the overall finish of the dome base and shade is not as professional as some may expect. Please make sure to view all pictures above prior to purchasing.

Sorry, these flickr references should work better than the ones above
Hi some weeks ago I had my first experience in the Red Sea with the Olympus Pen/ 8mm panasonic/ 4 inch Precision dome. The lense is sharp, very wide and other divers in your vicinity will likely pop up in your image. I solved this problem by cropping out a vertical part of the image covering the objects of interest .
I feel that this combo is ideal for CFWA: you will get a sharp image of both the foreground subject and background with apertures around f8/f11 . I works also fine with natural light and a filter on the lense.
I have been using this for 3-4 months now (with a Samyang 7.5mm Fisheye) and it has been easy to work with and seems pretty durable so far....granted, I may be a little over cautious with all my gear so my opinion may not count for much.
As for photos, since I am using it with the Samyang, I do get vignetting in the corners but nothing that some minor cropping doesn't eliminate...I still get a good field of view after the crop and the pics are sharp. Having the Panasonic 8mm fisheye would be the perfect lens but sometimes, we cut a few corners to get where we need to go.
Here are a few cropped pics with the Samyang under the Precision dome:
I bought this port for a trip to the Red Sea to use with the Panasonic 8mm fisheye as well as the stock lens that came with my E-PL2. It worked flawlessly and produced razor sharp images. I noticed a huge improvement in my photos using the 12-42mm lens - easier to focus and much less aberration. I was a little worried about scratching, but I just made sure to keep the neoprene cover on until I was about to dive in. I highly recommend this product.
I am just a beginner step up from sealife to M4/3. So, my review does not cover all the professional information, just plain fact about how I feel about this port.
I've been running back and forth between this port and Zen's product. Finally, I made the decision based on all the feedback, flickr's photos and great information that Scott shared here, and of course, the price. I am glad that I did.
The shipping and handling is great, no complain. The instruction and the accessaries came with the product is very well thought for diver like myself are hesitent to open a housing the very first time. The tools come with the package is wonderful, I'll say. Replacing the port took some effort due to olympus's original port is very well set, too well. I had to spend a lot of grip to "gently" pull out the factory port, but it's olympus' assembly line. Putting this new dome in the housing is very easy. But, at the end of putting the metal retainer back took some effort. The retainer is about 3 hairs (I will say 0.25mm) too wide. I filed the edge of retainer a little bit (0.01mm?) and apply a little force to push it in, then voila~ I am ready to dive with this baby.
I took this combination with my new Panny 8mm fisheye to Thailand. It needs some practices for the first timer (for example, myself). I had to get very close to the subject to compose the picture. And, yes, the strobes, I used my two old sealife strobes, (the yellow and the newer black ones... sorry, I am too lazy to get the model numbers). They just two basic flashes, but they worked file with minor adjustment (well, just turn the stobes outward).
It gives me 180 degree of view, at least I feel it that way. I have no problem about focusing. The dome is crystal clear.
I just have a few wish list for Scott
1) please just incluse the port cover in the package. I don't see any reason that any buyer would not spend extra dollars to buy this protector. I put the order for dome, but forget to add the neoprene cover (it's not listed when I order this dome). I'll say, just add it in as a complete package.
2) It will be great to provide the accessories on the web site, such as o-ring and lubricant for this dome. I understand it's better to send it back for annual service, however, I believe divers would like to have extra o-rings and compatible lubricant around.
3) well... I just hope to see more sample photos for self learning purpose.
I will recommend this product to anybody.
I use the dome with my 8mm pany fisheye and have a ball shooting with it. Just be careful not to let it bounce around rinse tub on the boat. I have a small scratch on mine, but does not affect the pictures. I really like the compact nature of the port.
Before buying the Precision Dome, I tried the Zen dome (300 bucks more expensive).
I can NOT tell the difference looking at pictures taken whit both domes.
Pros: Very sharp, compact, fast focus, acceptable corner vignettes, fits in any bag, neoprene cover is included.
Cons: some imperfections on the black plastic case, glass easy to scratch, hood screws get loose (allen included).
Bottom line: The cheapest way to get real Wide Angle UW photography, the extra $300 for the Zen port won’t give you extra image quality although Zen it’s better looking and more resistant.
This is a perfect addition to an Olympus housing. I use it with both the 8mm Pana fisheye & the 12mm Olympus prime lenses with an E-PL3. The whole setup is extremely compact. It works especially well for over-under shots with the fisheye lens. The housing with this port is slightly positively buoyant without the strobe; once the strobe is on, the whole setup is neutrally buoyant.
