I have tested both with 28-60 for stills. I have used CMC-1 and CMC-2 as well as stacking both, CMC-1 plus CMC-1 & 2. Regarding SMC, it depends on using the old SMC-1 & 2 or the new SMC-3. 1 & 2 are very thick which cause slight corner issues with both 28-60 and 90mm with 26-60 being more noticeable. CMC-1/2 and SMC-3 are about half as thick. If you intend to own both 28-60 and 90mm then the SMC-3 will be the better choice because it will work better with the 90mm lenses. If you intend to buy a 90mm read my review for the Tamron 90mm F/2.8 macro for Sony FE in issue #142 of uwpmag.com I owned the Sony for about tens years now and found the upsides of the Tamron to be better than those of the Sony 90mm macro. Also the savings on the Tamron will offset the higher cost of the SMC-3 over the CMC's.

Not only manual focus but no communication with the camera at all, so to have full control over the lens you would need a focus gear, a zoom gear and an aperture gear. You would have no meta date when opening files in software. Laowa only has one AF lens I am aware of and that is the excellent 10mm F/2.8 rectilinear for Nikon Z and Sony FE. I own this lens for Sony and the AF is excellent so Laowa has the ability to offer excellent AF lenses. The biggest upside to this lens is the amount of coverage it has received in the photo press, YouTube, social media and so on. Perhaps other lens manufactures will take note of the strong interest in a fisheye zoom for mirrorless camera users and consider finely offering an Auto focus fisheye for mirrorless.

The new Marelux Macroview MV-5 ($229.00 US) is on the way to me now. I will however be out of the US until August 2nd so will not have it in the water until after that date. This is a new design as Marelux is constantly improving product and I don't know at this time if the design will carry over to the current +10 and +15 which I have used. The new +5 has a max magnification of X2. Flabellina sp. with eggs taken today on the house reef at Scuba Seraya Resort, Bali Indonesia.

Zoom lens 60622? I don't recognize this part number. Sony simply has the most lenses that can be used with 28mm wet optics regardless of brand. It appears to me that currently only one wet lens can be used with the RF 24-50 behind aflat 67mm port and that is Nauticam WWL-C designed for 24mm's at 130 degrees. This is the least expensive of the NA-wet lenses and one would assume that other lenses like WACP-C, WACP-1 and so on would have better IQ from 28mm than the WWL-C simply because of cost. Marelux has a wet lens, Aquiista 100/67 also designed for 24mm at 120 AOV, this lens is also less expensive than the Aquista 120. When Marelux releases a port for the RF 24-50 a choice can be made between the two. I have not used the. A-100/67 so have no thoughts on full frame performance. Currently Marelux only has one APS-C housing for Canon R7. Unlike Nauticam, Marelux currently only has one port size, five inch or 127mm. As a result all ports and extensions work on any Marelux housing. So a port for RF rf 24-50 will work on any system and same for RF-S 18-45mm. The RF-S 18-45 is very similar in length to Sony FE 26-60 so I suspect it might work in the current Marelux flat port 32 but RF 24-50 will defiantly need its own 67mm flat port.

So first the Canon RF-S 18-45 is supported with a zoom gear because Marelux has a housing for the Canon EOS R7 APS-C camera. The RF 24-50mm FF lens works with several Nauticam wet lenses but I don't believe WWL-1B is one of them. It works with an N120 27mm flat port and WWL-C which is designed for 24mm lenses not 28mm and the rest are direct mount like the WACP-C and others. To make the RF 24-50 work on a Marelux housing a flat port in the 13mm range would need to be developed. The Nikon Z 24-50 will not likely be supported with a flat port (67mm) because it would need to fit inside the the Marelux housing. The Nauticam port is only 6mm so it would need to be about 9/10mm inside the Marelux housing.

Hi Chris, This is bit of a work in progress and no port chart or owner manual has been released. In the case of Sony FF mirrorless cameras the flat port 32 is used with the bayonet mount converter which threads to the 67mm port. Marelux has zoom gears for Sony 28-60mm which I use, this port also supports the Sony 28mm F/2 and the Sony 28-70mm with the addition of a 20mm port extension. The same port and lenses can also be used with WWL-1B as shown above. I believe Canon RF-S 18-45 (APS-C) is also supported with the same 32 port and can be used with Aquista 120 at about 120 degrees max rather than the full 130 degrees for full frame. In Nikon Z 24-50 is not yet supported with a zoom gear. The Aquista 120 I am testing is a prototype and did not include any type of float collar. I have used five float blocks (2oz each) and one 1500ml Flexibuoy on the strobe arms for best balance and balance.

Marelux has a zoom gear for Canon RF-S 18-45 which has been used on APS-C with a wide way lens. Have not heard at what point the RF24-50 will be supported. Marelux focus is on supporting Marelux wet lenses at this point. Marelux has several wet wide lenses including the Aquista 120 which I used Saturday’s (May 30th 25) for the South Florida Underwater Photography Society Meetup Dive at Blue Heron Bridge. The day was a bit overcast, water temp was a bit on the cool side and visibility was not the best. So a wonderful day for some close-focus work. My tools of choice, the Sony A7CR and Sony FE 28-60mm zoom in the Marelux MX-A7CR housing, with two Apollo S strobes and the new Aquista 120 Wide Angle Wet Lens. This lens is 130 degrees at the 28mm setting. Cushion Starfish at 28mm, ISO-320, F/20, at 1/160th sec. Octopus, horizontal shot at 48mm, ISO-320, F/14, 1/60th sec.

The 14-42mm is an Olympus M 4/3 lens with an Olympus M4/3 camera. The 7-14mm M 4/3 lens needed a larger than 180mm port to really work well. A 200 or 230mm dome with proper extension.

Saga dive is the only dealer I know that may be able to make a custom adapter.

In addition to being a manual focus lens requiring a custom focus gear the lens at 1:2 is only 1.42 inches (36mm) from the front of the lens. This means that in a 230mm port 1:2 would be inside the dome port even in a 180mm port sharp minimum focus would be inside the port. This means you won't be able to take advantage of minimum 1:2 focus or anything near it. Laowa has the 10mmF/2.8 AF in Sony and Nikon Z mount with a 12mm F/2.8 coming this year. The 10mm focuses even closer than the 15mm at 12cm and works very well in the 230mm dome with focus to the dome port. I owned the original version of the Laowa 15mm which also focused to 1:2. Great lens for nature in air but not very useful underwater. You can read my Laowa 10mm AF review at uwpmag.com in back issues.

Marelux has adapters for S&S and Nauticam N120 for use with WACP1/2 FCP, ports and extensions. They also have an N100 to Marelux 17mm adapter for WACP-C and WACP-1 in N100 I think it would work with other N100 ports depending on extension length needed. Sagadive.com also makes custom port adapters however cost V gain over buying a Seafrogs port with built-in extension may not make it worth the investment. AOI uses two different port mounts. Zen Underwater makes a port adapter for some of the Zen ports to AOI.

The 180mm F/4.5 which goes to 1.5:1 will be the first AF macro lens for full frame from Laowa. Laowa has already said their with be other macros lenses coming including something in the 55 to 65mm range. The 12mm F/2.8 (122 degree AOV rectilinear) will also be worth a look if it has a minimum focus distance as good as the 10mm's 12cm.

The first Fisheye I tested with Sony was the all manual Samyang/Rokinon 12mm fisheye and Sony A7R II around ten years ago. I used the Canon 8-15mm F/4 on Sony (with A1, A7&R 11, 111 VI, V, A7C, CI & CR) for over nine years in a verity of ports for the Zen 100mm to Matty Smith 12 inch port for splits. I also used a verity of both manual and AF lenses over the years and I have now added the excellent Sigma 15mm F/2.8 EX DG Fisheye with the Sigma MC-11 Canon to Sony lens adapter. This lens is very close focusing and while the AF is a bit noise it works well. My favorite combo is with the Marelux housings, 20mm port extension and the excellent Marelux 140mm dome port. This port is excellent because it includes a bayoneting sun shade which is easy to remove underwater when you want to go to 8mm and you can just slide it over your arm while shooting and then replace it for the 15mm end of the 8-15 zoom. Upsides to the Sigma 15mm include small size, compact system, no need for zoom gears for standard lens or when used with tele converters. I just started testing the Kenko 1.4X DGX HD Pro tele converter for Canon mount with 40mm extension and MX-140mm dome port and it looks very promising. I find it sad that over eleven years into mirrorless full frame cameras that Canon, Nikon and Sony haven't offered a native fisheye, not even a simple 15/16mm much less a quality zoom. After market sellers Like Rokinon, Tamron, Sigma and more have also over looked fisheyes as well even though they have been used by most sports and nature photographers for many decades. Attached are with the Sigma 15mm, MX-housing, 20mm extension and MX-140 dome port.

Another Fisheye option for Sony is the Sigma 15mm F/2.8 EXDG this image is using the Sigma MC-11 adapter. If you are more of a rectilinear lens fan the Laowa 10mm F/2.8 might be more your style if you are willing to deal with a 230mm dome port for best results.

This week Marelux has announced three new and innovative products. The Marelux Artemis 3000 RMT video light which has 3000 lumens of white light output, 1000 lumens red light output and 600 lumens blue light output all at 100% with four steps of dimming. The light has a 120 degree beam angle and uses two 18650 3.7V lithium batteries. The Artemis 3000 also has video mode control and a remote control mode to trigger the camera shutter from up to ten meters away using the new remote shutter module. The remote shutter module is fitted inside the housing and can receive a blue light signal from the Artemis 3000 at receiving angles up to 140 degrees. This new tech allows you to set your housing system on a tripod or other stand and them fire the system remotely from up to ten meters away without using a trigger cord, perfect for shy subjects like Garden Eels and many other burrowing animals. The third new product is called a terminal flash repeater. This works in conjunction with the Marelux LumiLink wireless flash trigger to fire non-Marelux optically triggered strobes of all makes. During the November DEMA show the LumiLink 2.0 optical transmitter was a hit with many photographers looking to fire strobes remotely without hiving to use slave-light or long optical cords or other triggering devices. Many of those interested ask if Marelux could develop the same tech for non-Marelux strobes that fire optically. The terminal flash repeater can be used to fire strobes remotely from as far away as ten meters. Simply attach the device to your strobes using a short sync cord and they can be fired in manual flash mode, in continuous shooting mode and high-speed sync modes above 1/200th sec. using the LumiLink as the triggering device. Both triggering devices use the patented Marelux signal from camera/housing which is encrypted into a blue light signal to the receiving device. Go to the marelus.co products page for more information
