#374547 Nauticam Compact Macro Converter

Posted by Phil Rudin on 14 June 2016 - 12:37 AM

Hi Alex, The SMC was basically designed for full frame and the CMC was designed for sub full frame and works the best with M43. This is the C/U lens that would be my choice for M43. CMC and CMC-1 are the same thing. 


The problem with the C/U lenses is that many people use the lens before they have reached 1:1 with the 60 and other macro lenses. As a result I see images of animals much larger than the 17.2mm X 13mm life size of the m43 60 macro lens. So as Bill has said in the hands of someone who knows how to use the C/U lens you can get excellent magnification but many are using like a placebo only think they are getting higher magnification. 


These are images I have posted here several times, the configuration is EM-1 60mm macro manual focus to 1:1 (life size) then move the housing until in focus. First is the 35mm slide as a frame of reference, the 60mm life size and then 60mm at life size plus CMC. As you can see a very small final image taken a less than 10mm and very shallow DOF. Most people are not getting this close even when they use a C/U lens.


So you can see full frame life size and the final eye image and make your own evaluation of how close that comes to 7:1 magnification.

#374128 A7R II and FE 90mm Underwater -- first dive with Sony

Posted by Phil Rudin on 30 May 2016 - 06:48 AM

I have found that this lens becomes more user friendly after a few outings. I use the 0.5 to 1:1 focus limiting setting when using the lens as most of my subjects of choice seem to fall within this range. I also use the Nauticam SMC-1 with this lens. I will be using this equipment in the Philippines next month along with the new Zeiss 18mm and a Canon 8-15mm fisheye zoom.

#373302 Are people leaving micro four thirds?

Posted by Phil Rudin on 04 May 2016 - 01:55 PM

Hi Tom, I was skeptical also but had several chats with design teams from two major manufactures of dome ports and both confirmed that the flange distance, in this case about 22mm rear lens element to sensor for Sony full frame mirrorless and about 42/43mm for Can/Nik FF DSLR does in fact make a difference with lenses of like angles of view. The result is that smaller domes can be used with mirrorless cameras with the same sensor size as a DSLR and still achieve like results.

#369494 More magnification ....

Posted by Phil Rudin on 20 January 2016 - 10:32 AM

This is a standard test for the Olympus 60mm macro, manually focused to 1:1 all photos taken by "rocking" the camera to obtain focus.


#1 photo is the setup tapping a bill to a 35mm slide mount and onto a window for back lighting.


#2 is 60mm at 1:1 17.3mm on the long side


#3 is using a SubSea +10 C/U lens. Image approx. 13mm on the long side.


#4 is using a SAGA +15 C/U lens, as you can see at +15 the image is 8mm on the long side I don't know how much more magnification you need.


The Nauticam CMC-1 is by far the best C/U lens for the 60mm macro at apex. 8.65mm on the long side.

#369330 Macro with the A7R II & Sony FE 90mm macro

Posted by Phil Rudin on 15 January 2016 - 08:20 AM

Hi Brent, The Sony FE 90mm macro is an incredibly sharp lens. Like most Zeiss lenses it is heavy glass. My conclusions have been that the AF works quite well above and that below water sharpest focus is achieved when going manual focus from about 1:3(2.5) to 1:1. This can be accomplished with rear focus by AF and then rocking the camera or by using a manual focus gear. Keep in mind that full frame apples to apples with sub full frame has shallower DOF at any given F/stop so smaller focus range. I used the same technique with M43 cameras below about 1:2 so not much difference in that regard. For video I would be going full manual. I hope this helps.

#364997 Macro with the A7R II & Sony FE 90mm macro

#364621 Any experience with the Sony A72 or A7r2?

Posted by Phil Rudin on 25 August 2015 - 09:06 AM

Nauticam NA-A7II housings now support both the A7 II and A7R II camera bodies. All housings going forward from serial number A151096 will have the upgrade to support the A7R II mode dial and past housings can be upgraded. I received my housing yesterday ‪#‎A151098‬ with the upgrade installed. Nothing about the housing has changed other than the mode dial upgrade. Photos attached.


My Sony A7 II/ Nauticam NA-A7II review should be posting on 1 Sept. in the Sept/Oct issue of uwpmag.com, this is a free PDF download.

#363725 Why Sony A6000 - didn't become the " main/most" importent camera...

Posted by Phil Rudin on 29 July 2015 - 07:21 AM

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. 

#363472 NEX Macro Option?

Posted by Phil Rudin on 22 July 2015 - 06:53 AM

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.

#363099 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by Phil Rudin on 10 July 2015 - 12:40 PM

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.

#361550 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by Phil Rudin on 27 May 2015 - 06:48 AM

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.

#360417 Thoughts on the OM-D E-M5 Mark II or the upcoming Panasonic's?

Posted by Phil Rudin on 23 April 2015 - 07:39 AM

I have the E-M5 II in Cozumel Mexico and I am finding the AF to work quite well with my Olympus 60mm macro lens. I am using a new Ikelite prototype housing with two Ikelite DS-161 strobes. The attached photo is with the 60 macro and Nauticam CMC closeup lens, image about 8.5mm on the long side. I use S-AF so no comment on how the C-AF may work with this new camera. Now if I could only get a software update that includes this camera for LightRoom 5. The new LRT 6 includes the camera but with the internet here it would take two days to upload.

#358833 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by Phil Rudin on 14 March 2015 - 07:31 AM

EpsenB, I think you are over reacting at bit regarding the issue of the new Olympus 7-14mm F/2.8 zoom. Nauticam has a 85mm to 120mm extension with a zoom control allowing you to use the 180mm optical glass dome port (120mm on the housing side) with the current mirrorless Mini housing line. After the adapter is mounted the lens is installed from the front of the housing and then an additional port extension and the port are installed over the lens. This works well for lenses like the Olympus 12-40 zoom and the Zeiss 12mm on Sony NEX and A-APS-C series housings. The zoom gear would be operated from the extension and not the housing zoom dial. I am sure that ZEN Underwater will also have a port solution for this lens going forward. The issue will be to determine the amount of extension needed for this lens. Olympus 12-40 and Panasonic 12-35mm use 20mm of extra extension, Panasonic 7-14mm no extension, I would expect Olympus 7-14mm be be in the 20 to 25mm range if this system does in fact work. The 85 to 120 extension would actually work with any of the ports with the 120mm port mount so you could in theory go to a 230mm port if you wanted with the correct amount of extension. The extension part number is 36052 on the Nauticam port chart.

#358778 A6000 doesn't let you set shutter speed higher than 1/160 > When b.i...

Posted by Phil Rudin on 12 March 2015 - 06:48 AM

The Nauticam flash trigger is a product I am well aware of but it does not resolve the issue of the 1/160th shutter speed. At best you may get one additional stop of shutter speed and not all cameras will have any change in sync speed. You will not know without testing the product with your camera.

This Nauticam product was designed originally for cameras that don't have an included flash or on-board flash like Sony A7 series cameras.
