  1. I use the 45 degree finder for both macro and wide angle, it is excellent in macro for getting the lens low and on the same plain as the subject. I also review in the viewfinder and have the camera set to a one second review which is more than enough to see the histogram. I replace the 45 finder with the stock pickup finder for fast moving subjects like shark photography. The window has two O-rings, one that seals the window in place between the lucite and the housing, the other is installed from the inside of the housing to hold the window in place.
  2. I am also a big fan of the 45 finder and it is a great asset for macro. Yes, the back window needs to be replaced with a new one that has support for the 45 finder, it is around $240.00 US new. It is user replaceable and takes less the a minute.I am selling the window for the NA-EM1 housing if anyone in the US is interested , send me a PM.
  3. This is the Nauticam port for the 90mm macro and NA-A7II housing. Has a mounting point at the front for a focus light. Seems very well balanced when used with the attached float arms and Inon Z-240 strobes.
  4. With a small sensor camera like the M43 cameras one of the big upsides for CMC is the fact that it puts more distance between the port and subject. It is also about 1/3 the depth of SubSee and SMC. SAGA also has a very complete line of closeup lenses which also work best with smaller sensor cameras ( from +5 to +25 diopters in strength).
  5. No not at this time. When I do a product review I usually try to stick to what the camera manufacture has in their lens line.
  6. I have attached a Sony E-mount article with images from several E-mount camera and my approach to building a system. http://www.talkemount.com/threads/13261/ Sony A7 II, Sony FE 90 mm macro, Nauticam NA-A7II housing, Two Inon Z-240 strobes, ISO-200, F/11, 1/125th.
  7. I use the 60mm macro lens set to 0.4m to 0.19 or life size (1:1), if I want to shoot beyond 0.4m I will be choosing another wider lens like the 12 to 40mm F/2.8 zoom. At 0.19 the image area captured is about 18mm on the long side and 17.3mm if you use the manual focus gear. The AF does not get all the way to 1:1 in most cases. If the original poster has never used a macro lens of this magnification underwater it will be an easer learning curve if you remain within this short working distance range, the lens will hunt less. Adding any closeup lens like Nauticam CMC for greater magnification before you are competent with the lens alone will only further frustration. With CMC image capture is about 9mm on the long side at less than 10mm to the subject. The Nauticam CMC-1 is designed for best results with M43 sensors and smaller like the one inch compact sensors. SMC is designed for full frame and APS-C sensor cameras and will preform better with those sensor sizes. Olympus 60 macro is an excellent lens when used within its limits with best results at or below F/8. M43 sensors have huge DOF so macro at F/5.6 to F/8 will work quite well even with the CMC-1 where most subjects will have little depth at only 9mm in length.
  8. Starfish, the Nauticam A-6000 housing has a control to pop up the flash in the event you forgot to do that before closing the housing and also to retrace the flash in the event you want to do that during the dive. Wide angle is covered with the Ziess 12mm and the 10-18 F/4 both supported with ports. I was not all that impressed with the 16mm with fisheye converter and some feel that the Ziess macro offering is expensive V. the rest of the system. Regarding lens size v. M43 the lenses will always be bigger just as they are with mirrorless APS-C v. full frame mirrorless. The big difference is that the ports remain smaller v. DSLR ports, I.E. 180mm port on full frame for 16-35mm zoom v. 230mm port for same zoom range on full frame DSLR. Sync speed of 1/160th is behind the curve compared to Olympus 1/320th and excellent lens line.
  9. I think it has been well documented that AF speed both in S-AF and C-AF has improved with each new Alpha 7 release, AF is also only one aspect of a complete underwater system. I could argue that 5DIII and D800 do not have 5 axis image stabilization and EVF or that the A7 II with 16-35mm zoom has better corner sharpness with a 180mm port than the C/N 16-35mm lenses have with a 230mm port. These features may be important to some and not to others, these are choices we each have to weight when investing in new equipment.
  10. Can't speak for the A6000 but it focuses seems in line with other macro lenses I have used of about the same focal length when used with the A7 II. I use the focus limiting range of 0.5M to life size (1:1) which may not be on your other macro lenses. I would expect focus speed to be even better whit the new A7r II when it is released. Apples to apples that might be a better comparison V. 5D3/D800.
  11. I think I should have started a new thread for this lens so people won't need to hunt for information on the lens. I use 0.5-.28m or half meter to Life Size (1:1), this takes a bit of time to learn because you will backup for the lens to focus on some occasions. This is resolved by just getting closer as you should for macro. My first review will involve the 90 macro and the 16-35mm zoom with the recommended 180mm port configuration from Nauticam. I will be doing a later review for the A7r II which I hope to include more lens options. I will not be investing in any more lenses until after DEMA in early November any new lenses should be announced by then. I do not own the 28mm with adaptors but I may have a chance to borrow those for my next review after Nauticam has announced the port configuration for those adapters. A few more pix form yesterdays dive with the same housing setup.
  12. Regarding the port you are correct Atobit I am using a standard flat port with an extension that most closely fits the lens, however the lens sits back in the port at least 10-12 mm. This will greatly reduce the magnification with any C/U lens so I have not yet tried my C/U lenses yet. If you have followed my reviews you may be aware that I not reviewed a full frame camera in some time so most of my current close up lenses are designed for smaller sensor cameras I.E. Nauticam CMC-1 and SAGA +5 and +15. Best results will come from SMC, ReefNet and Inon. Regarding built quality it is excellent. For above water work the lens has a focus hold button and for U/W it has focus limiting in the .4 M to 1:1 range which is what I used for my first dive with the lens yesterday. Focus is quite accurate and the image quality is higher than any macro I have ever tested. Cost is in line with or below other full frame macros from other camera makers. Mirrorless bodies allow lenses like the Olympus 60mm macro to be smaller than full frame lenses, while the Sony A-series full frame lenses are smaller than most of the like DSLR lenses they still need to be bigger than lenses for sub full frame cameras. So the only downside to the Sony 90mm macro may be its size relative to the A7 series bodies. Can't wait to test this lens on the A7r II coming next month. If you like bench testing reviews DXO Marks has just posted a review for the Sony 90mm macro on the current Sony A7r body and it got a through the roof 40 score. They also tested the lens on a ASP-C sensor if you would like to look into it. What drew me to this system which I am now reviewing for a future issue of UWPMAG.com is the quality of the lenses being introduced by Sony. While the lens set remains small compared to Canon, Nikon, Olympus and others the few lenses I use use underwater are all excellent.
  13. First dive using the new Sony FE 90mm F/2.8 macro with the Sony A7 II in a Nauticam NA-A7II housing, Two Inon Z-240 strobes shot in manual. All shot at ISO-200 using EFV and Nauticam 45 degree enhancement viewfinder. Octopuses eye F/16 at 1/250th, LizardfishF/11 at 1/125th, Batfish F/11 at 1/125th. This is one outstanding macro lens.
  14. The ZEN Underwater solution for both the new Olympus 7-14 and 8mm lenses is now posted on the Wetpixel front page. Solutions for both Nauticam and Olympus housings.
  15. I have used both ZEN 170mm ports, open water shot is ZEN type I with the Olympus 12mm F/2 and the pool shots are with the ZEN type II (longer extension for the Olympus 12-40 F/2.8 and the Panasonic7-14mm zooms). The pool shots are also at 12mm with Olympus 12-40mm F/2.8, I like 12mm for people shots and find the corners look very good compared to some of the wider AOV's of the 9-18 and 7-14mm.
  16. Three reviews this issue, Canon G7x in the Fantasea housing, Olympus E-M5 II in the new Ikelite housing and the Ikelite fluorescence equipment. UWPMAG.com is a free PDF download for those who have not read it before. Lots of great information for underwater photographers.
  17. According to the specs. at B&H photo the Panasonic 8mm is 35mm longer than the Rokinon, 518mm v. 483 for the Rokinon. This puts the lens further back in any of the 8mm ports which is likely what is causing the vignetting. I don't think you are going to find a port that sites any closer to the housing than the 3.5 inch dome so you may be out of luck.
  18. I have one on order for Sony FE mount and at the very least I think this will be an excellent travel lens. The lens was announced widely on the same day and I found the release information on at least six different sites. As a result the business web site was down for at least four days perhaps because of the wide amount of interest overloading their system. I am sure this lens will not be main stream but like the Inon bigeye lens I am sure some will find a way to use it underwater as they have with some of the excellent Rokinon lenses. The tilt feature may be handy for the required hotel shot for many destination reviews.
  19. I can assure you Richard that the Zen 170mm and the Nauticam 180mm are not the same glass.
  20. The revised Nauticam port chart for Mirrorless M43 housings shows two gears for Olympus 7-14mm F/2.8, #36054 & #36055, also N85 to N120, 55mm extension #36401 and Optical glass port #18809 the 180mm port. Same system also works for 12-40mm F/2.8 with gear #36045. The Olympus 8mm F/1.8 Fisheye port system is not yet posted, but I am sure will come soon.
  21. In the FE lens line the new 16-35 mm F/4 zoom is looking good in a Nauticam 180 mm optical glass port V. 230 mm and higher ports for the same zoom range on full frame DSLRs. Also the soon to release FE 28 mm F/2 (well priced) with 21 mm and 16 mm fisheye adapters looks interesting. Nauticam port roadmap has the 28 mm and both adapters as a work in progress. Also a port is coming for the about to be released 90 mm F/2.8 macro. More info at Nauticamusa.com contained in the Sony A7 II press release.
  22. The extension ring is the same part used with the Olympus 43 series housings (E-300, E-330, E-400/410 %20 Ect.) for use with the 1.4X teleconverter. The extender could be used to add the TC to the 50mm macro lens or to extend the 8mm fisheye. These parts are also sold by Inon, Athena and more. The dome is the same 170mm optical glass port used with the Old 43 Olympus 7-14 and a longer extension. The only new part is the gear. http://www.ebay.com/itm/Olympus-PER-E01-for-lens-port-EC-14-EMS-SPEEDPOST-/111015853971?pt=LH_DefaultDomain_0&hash=item19d90f7f93 http://www.ebay.com/itm/OLYMPUS-PPO-E04-ZUIKO-DIGITAL-ED-Waterproof-Camera-Case-Lens-Port-7-14mm-/251910695061?pt=LH_DefaultDomain_0&hash=item3aa70c2895 The new port for the 8 mm F/1.8 Pro is already in the Q at http://reefphoto.com/shop/index.php?main_page=product_info&products_id=8289 Unfortunately the new Olympus E-M5 MKII housing reverts back to the PEN housings port system.
  23. Extension length will depend on which port you may be using and at this time I don't have an answer for that.
  24. When Panasonic introduced the 8mm Fisheye in 2010 the price announced was £729.99 ($1071.00US) so $999.00 for the Olympus 8mm F/1.8 PRO is not at all out of line for a very high quality lens which is completely weather sealed and so very fast. This lens is not for everyone and is directed like the rest of the "PRO" line at highness shooters, professional photographers and more. While it is a great lens for underwater use it will also appeal to above water photographers as well for things like astro photography. I have used the Panasonic 8mm underwater for five years and had a chance to use a prototype Olympus 8mm F/1.8 two weeks ago. I can tell you that it is very fast focusing and has outstanding image quality. Current ports for the Panasonic 8mm will need new extensions or a new port design for those not already owning a port. Olympus has also released a new port for this lens for the port mount used on their E-M1 and E-m5 type housings. As Draq has said more speed requires larger and heaver optical glass elements I don't thing at a little over 300 grams (about 11 oz. for the metric challenged) that the weight is a huge tradeoff for such a fast lens. Nikon 10.5mm fisheye is an F/2.8 lens v. the Olympus F/1.8. Are you referencing auto focus speed or the speed of the lens as in F/2.8 v. F/1.8. For those not interested in the extra speed of the Olympus at f/1.8 the Panasonic 8mm is a fine lens and it is nice to have choices.
  25. First let me say that both the Olympus 7-14 F/2.8 and the Olympus 8mm F/1.8 fisheye are even more impressive in the flesh than in the photos on the interweb. I used the 8mm last week and it is excellent with. Both lenses are being tested and the main issue is getting the correct port extension for the very best possable corner sharpness for the port size. I am sure both Nauticam and ZEN will have solutions for these lenses around the time that they are released. The build quality and image quality of both lenses exceeds what we have seen from M43 wide lenses so far.
