#400573 Nikon Mirrorless cameras - Z6 and Z7

Posted by Phil Rudin on 06 November 2018 - 09:27 AM

I would agree with Todd in regard to the Nikon Z7. The biggest issues being thrown out are the lack of two card slots something that would not have even been noticed there or four years ago. Others issues include the 1/200th sec. top flash sync and the AF-C. Image quality is in a word superb and on the same level as the D850. I had no issues with AF-S during you short one day use of the system. 

 

Regarding growing pains like Sony, Olympus and Panasonic when they went to mirrorless a full set of native lenses will take a while to roll out. That is what makes the MWL-1 and SCM-1 & 2 lenses so ideal for this system. With the FTZ DSLR lens adapter and the current Nikon 60mm F/2.8G macro this one kit can cover a very wide range of view all on the same dive.

 

Looking forward to seeing offerings for the New Canon EOS R system at next weeks DEMA show.

#400503 Nauticam Macro to Wideangle Lens 1 (MWL-1) for Full Frame

Posted by Phil Rudin on 02 November 2018 - 07:10 AM


I had an opportunity to use the MWL-1 with the new Nauticam NA-Z7 housing and Nikon Z7 camera two weeks ago. The system was outfitted with the Nikon 60mm macro for DSLR's and the Nauticam SMC-2. The lens ships with a neoprene dome cover and my test unit had the Nauticam dual flip adapter. My test unit did not have a buoyancy collar and I used float arms which seemed to offset any imbalance. The Nauticam housing for this camera is excellent. The Nikon Z7 has the same growing pains found with the first generations of the Sony A7 cameras and other mirrorless offerings. Build quality of this camera is superb the best of any mirrorless I have used so far, excellent weather resistance. I only had the system in the water for about two hours so hardly enough time for a full review. I did like the idea of being able to cover from 150 degrees AOV down to 4X in macro. Attached are MWL-1, 60 macro and 60 macro with SMC-2 photos.
 
If you would like more information go to UWPMAG.com and download the latest free issue for my thoughts on this system.

#400443 Nauticam Macro to Wideangle Lens 1 (MWL-1) for Full Frame

Posted by Phil Rudin on 30 October 2018 - 08:58 AM

Simon, On full frame the Nikon 60 macro has an AOV of 40 degrees, on M43 Olympus and Panasonic 30 macros have an AOV of 40 degrees with the 2X crop factor and all three go to life size (1:1). All three also have a 150 degree AOV using the MWL-1.

 

Zeiss 50 macro on APS-C has an AOV of 31 degrees with the 1.5X  crop factor and focuses to 1:1. On Sony and Fujifilm the AOV is 115 degrees with the MWL-1

 

Canon does not currently offer a AF 60 macro for full frame.  The Canon 60 macro for APS-C with the 1.6X crop factor has an over 24 degree AOV which appears to be too wide for the MWL-1 lens. 

 

SMC-1 & 2 were designed more for full frame and APS-C while CMC-1 & 2 are more suited to M43 and compacts. The problem with the 30 macro on M43 V. the 60 macro on full frame is the difference in minimum focus distance. The 60 macro gives you around 18+cm while O&P 30 macros give around 10cm making the distance to subject very shallow even without the addition of a C/U lens.

 

The upside to the MWL-1 which is being overlooked by some is the superb image quality and corner to corner sharpness. In the case of M43 the closest lens with this image quality would be the Olympus 7-14mm F/2.8 zoom combined with a port of at least 180mm (200mm is better) and proper extension. I know many M43 shooters that have just that configuration and the cost is around 2870.00 while the cost of the MWL-1 with 30 macro and port is around $2450.00 with the more expensive Panasonic 30mm F/2.8 macro.




#400410 Nauticam Macro to Wideangle Lens 1 (MWL-1) for Full Frame

Posted by Phil Rudin on 29 October 2018 - 11:42 AM

I can answer a few of your equations, first it is 110mm in diameter including the hood so smaller than the 130mm of the WWL-1. The MWL-1 is only a few grams lighter than WWL-1. The MWL-1 can be used on Nauticam single or dual flip adapters  with a macro lens like SMC-1 & 2 on the dual. MWL-1 is designed to be used with dedicated macro lenses that are 60mm and focus to 1:1. So full frame Nikon 60mm, Olympus and Panasonic 30mm macros. With these three lenses you can focus from the port glass and the AOV is 150 degrees.  The lens works across platforms from for full frame, APS-C, M43 and some compacts with variations in the AOV from each. The Nauticam.com port charts list the cameras and lenses tested so far. Other lenses may not have been tested at this time or they just don't work. 




#392475 Flotation for E-M1 mk ii

Posted by Phil Rudin on 18 February 2018 - 09:53 AM

I have owned the Athena 200mm port as well with the threaded Olympus style mount for the 4/3 housings like the Athena housing in the attached photo. This was during an advert shoot in Las Vegas for Turnberry Co. using an Olympus E-3 and Olympus Zuiko  8mm F/3.5 lens. It also worked very well with the Zuiko 7-14 DSLR lens.

#390690 New Inon Z330

Posted by Phil Rudin on 31 December 2017 - 09:27 AM

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.

#390444 New Inon Z330

Posted by Phil Rudin on 20 December 2017 - 10:12 AM

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. 




#389337 Shooting Experience - Oly 30mm vs. 60mm Macro Lenses

Posted by Phil Rudin on 12 November 2017 - 09:49 AM

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.   




#389285 Mini Flash Trigger Nauticam #26309 for Gh5

Posted by Phil Rudin on 10 November 2017 - 10:49 AM

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.




#389284 Shooting Experience - Oly 30mm vs. 60mm Macro Lenses

Posted by Phil Rudin on 10 November 2017 - 10:42 AM

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.

#387004 Nautical Mini Flash Trigger for Olympus (#26306) on a E-M5 mk.I?

Posted by Phil Rudin on 26 August 2017 - 02:34 PM

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.
