  1. My reviews of these new products are now released in issue #100 of UWPMAG.com. This is a free PDF download until issue #101 is released.
  2. Hi Berry, Yes the Z-330's performed well. My review should post in the next two or three days at UWPMAG.com
  3. Last nights black water dive (12/30/17) north of the Palm Beach Inlet, Florida USA in 500 feet of water. Very slow north current, only covered about a mile. Olympus EM1 II, 30mm macro lens, Nauticam NA-EM1 II housing, two INON Z-330 strobes.
  4. For those concerned about heat buildup inside the Z-330 strobe this is what has been improved over Z-240. It may be hard to recognize in the photos you have seen published but the front of the strobe has a new design. The ring around the new front dome is made of a black metal (I would assume aluminum) rather than the Polycarbonate resin used in Z-240. This metal ring is connected directly to the internal circuitry allowing heat to be effectively released into the surrounding water. The surface area has been maximized and the metal ring also butts up against the threaded aluminum ring used to attach the light shade. The bayanot style soft defuser that ships with the strobe also has the fresnel design on the backside and only reduces output by about -0.3 stops.
  5. First of all the topic is shooting experiences with the Olympus 30mm macro V. the 60mm macro lens. The issue with the Olympus 30mm macro is VERY limited working distance and the port you are using. With my Nauticam NA-EM1 II the 45 port is recommended. In that port the front of the lens is about 10mm from the outside of the port glass leaving a working distance of about 10mm between subject and port at 1.25:1 or maximum magnification. Using say a plus 10 closeup lens would reduce the distance to 5mm plus the thickness of the CU lens would leave little to no working distance. In addition the CU lens would be at least 10mm from the front of the lens which would reduce the magnification of the lens because of the distance between the two lenses. Also the Olympus lens is already a 1.25:1 lens which at 1.25:1 is about the same amount of magnification as you would get with your Panasonic lens at 1:1 plus the ULC-165 wet lens. This is assuming that your lens is closer to the port glass on your housing. With the very best placement your lens at 1:1 plus the the Inon UCL-165 would get you to about 1.3:1. For subjects the size of a Pigmy the 60mm macro is just the far better choice and at 1:1 you can use about +25 of magnification in front of the lens before the working distance becomes to limited. This would give you magnification of about 5:1 or a subject about 3.5mm on the long side.
  6. OLYMPUS which has just gone on sale in the US for $199.00 for other readers who may be interested.
  7. On Olympus you can not over come the 1/250th sync. speed and my flash trigger works fine with single fiber cables. The problem is with the cables not the flash trigger most likely.
  8. This again is a bit like comparing apples to oranges. The 30mm has twice the angle of view and twice the depth of field V. the 60mm at the same F/number. The 30mm does not work with closeup lenses because of the close focusing distance while the 60mm works quite well with +5 to +25 amounts of magnification. This is a bit like comparing the 7 mm end to the 14mm end of the Olympus zoom. Both work very well for what they were designed for. I look at the 30mm as a 1:3 or greater size lens while I look at the 60mm as a 1:3 or smaller size animal. If I am looking to do super macro 60mm is my choice Fabio's which are all in the appox .1:3 or larger range the 30mm works great. For an under $300.00US lens the 30mm has excellent image quality and is easer to use because of the wider angel and greater DOF. I find the 30mm to be an excellent black water lens because the 60mm is a bit difficult to focus while I and my subject are both moving. Bottom line is I would own both if you can afford to do that because they simply don't replace each other. Photo is from a black water dive and the subject is a little larger that a US quarter, Larval Stage Sea Anemone, 30mm, ISO-200, F/7.1, 1/250th sec, two Inon Z-240 strobes, Nauticam housing and 45 port.
  9. Carry I have the N100-N120 35.5mm port adapter, the 16/35 zoom gear and the Nauticam 180mm optical glass port. You will also need a 50mm port extension. Contact me at tropicalone@bellsouth.net if you are interested in any of my equipment.
  10. It is never an exact science, even though both lenses have a minimum focus distance of 20mm according to the specs that does not mean they both have the same nodal point. Should be a good starting point.
  11. I use the Olympus 12mm F/2 underwater for models and other work also a stellar low light lens with excellent image quality. I have used the lens with the following dome ports, Zen Underwater 100mm, Zen Underwater 170mm, Zen Underwater 200mm, Nauticam 180mm and Nauticam 140mm Fisheye. For split images the bigger the better (ZEN 170mm for the attached split image) but you can get away with the 140mm if you have fairly calm water. I really like the Nauticam 140mm because the lens focuses all the way to the port glass. With the Olympus 12mm F/2 a 20mm extension is required. I can also use the Olympus 8mm F/1.8 Fisheye with the N140 and a 17mm extension. Since the Panasonic lens is 70mm in length V. 43mm for the Olympus I would expect you to need a longer extension with the Panasonic lens. The B&W photo is with the Nauticam 140mm and 20mm extension. I love the small and light combo of the Olympus 12mm and N140 port.
  12. As a side note having been one of the many who used the Nikonos RS for years a lens that is even harder to find is the Rene Aumann 18mm rectilinear lens. He also made a 2 X tele converter for the Nikonos RS 50mm macro which I used extensively. This one is for sale in the US at KEH Camera reduced to $698.00.
  13. The Sept/Oct issue of Underwater Photography Magazine, uwpmag.com has posted with my cover shot and articles covering the Olympus EM1 II/Ikelite housing, Olympus 30MM macro and Inon UCL-67 M67 closeup lens. This is a free PDF download.
  14. YES the lens is still available and as the add says I will pay for the shipping with a tracking number. You can contact me direct at tropicalone@bellsouth.net.
  15. No, unless you are doing split images in which cals the bigger the dome the better.
  16. The ZEN port is excellent with the 30mm extension for the Olympus 8mm Fisheye. The Nauticam port is also excellent and can be used with the 20mm and 17mm extensions for both the Olympus 8mm Fisheye and the 12mm which is a great lens for models.
  17. Excellent glass with no damage, 67mm threads, New-$179.00 will sell in the US 48 for $125.00 including shipping.
  18. Excellent glass with no damage, 67mm threads, New $225.00 Selling for $160.00 shipped in the US. 48.
  19. E-M5 has the wedge in the front half of the housing (to deploy the onboard strobe if you forget) which would prevent the flash trigger from fitting into the housing. The E-M1, E-M5 II and E-M1 MkII all use the taller removable strobe that does not require the wedge to pop it up. I use the Nauticam flash trigger with my NA- EM1II Nauticam housing. With the camera set to C-AF TR and Sequential High setting I can hit 18 properly focused frames per second using my Inon-240 strobes at about 1/4 power in manual. It is quite impressive and beats many of the much higher cost full frame cameras.
  20. The current UWPMAG.com #97 has my review if you care to read that, I have used both port plus several more for the M43 8mm Fisheyes.
