  1. The WWL-1 and WWL-1B also work well with the Marelux housings for Sony with the 32 port. Be aware that with the WWL-1B you will need to shave off about 5/10mm of the blue release lock to make it work on the shorter Marelux housing.
  2. Again the prototype I used is pictured in the attached article and if you read the text you will see I used the Panasonic 14-42 power zoom lens because that was the system I was given to assess and provide feedback. Since you tested the lens a few months later I am not sure if you had a more updated version than the one I used. When I reviewed the WWL-1 with the Sony A7R III and Sony FE 28mm F/2 that is also he system I was provided. The fact that the image quality was better with the higher resolution camera and higher quality lens is not an indictment of the M43 lenses or EM-1 it is just a simple statement of fact. Further WWL-1 is excellent for full frame cameras like Sony A7C using the high quality Sony FE 28-60mm zoom. It will also works well on high MP cameras like A7R IV and A-1 so while I understand the premise of WWL-1 M43, WACP-C APS-C and WACP-1 full frame all three wet wide lenses work very well on full frame given the correct camera lens combinations. I think what is important for many readers to understand is that Nauticam put a lot of time, energy and expense into this and the following projects. They also reached out for feedback from a well rounded group of users world wide before releasing the finished version.
  3. When I first used the WWL-1 prototype in March of 2015 it was with an Olympus M43 camera and 14-42 zoom lens. You can see in the attached review (upper right) that the lens mount looked much different than the final WWL-1 at retail release. Not sure if this is the same prototype design that 121 used later in the year but I think we all recommended some type of buoyancy device and a better bayonet mounting system, I am sure Peter Rowlands and I did. Later in the year or early 2016 Nauticam USA allowed me to take the lens to Cozumel for three weeks to use with a Sony full frame mirrorless system and the Sony FE 28mm F/2. I found the results from the 28mm 130 degrees superior to the M43 system at 14mm 130 degrees. I think for Sony full frame users the 28-60mm has added a great deal of flexibility to the Sony full frame systems. The 28-60 pairs very well with WWL-1/1B, WACP-C and WACP-1. I have used the WACP-1 with the Sony FE 28-70, 28-60 and Tamron 28-75 F/2.8 and my first choice would be the 28-60 because of it speed in auto focusing and overall image quality. With the WACP-2 I wanted to use the stellar Sony 14mm F/1.8 which has both a fast aperture and AF speed. Because it requires an N100 to N120 25mm port adaptor which I could not source I was only able to use it with the Tamron 17-28mm F/2.8 which does not take advantage of the full 140 degree AOV. I received the WACP-C only days before a non-diving four week trip out of the US. This lens also appears to work very well with the Sony 28-60 during the limited time I have had the lens. As Alex has said each of use who have been able to use all of the wet wide lenses with a verity of primes and zooms have varying experiences and preferences regarding what combination works best for them. I think for me based on limited use that WACP-C will be my choice for Sony full frame along with the three Sony lens (28mm, 28-70 and 28-60) that I already own.
  4. "So I am not at all surprised that if you take the same Sony 28-60mm lens which is a slow but sharp lens and try the WWL-1 WACP-1 WACP-C you see small differences between them". Not trying to be picky 121 but I am not sure of your your definition of slow is but the Sony 28-60 will AF at the A-1 top speed of 30 FPS. That is twice as fast as the older Sony 28-70 and 28mm F/2. That is also as fast as the Sony 12-24 F/2.8 you referred to. Also the fact that the lens is made of "plastic" in China does not mean it is of cheap construction. Many of Sony and others top quality lenses are made in China. The Nauticam WWL and WACP line are also made in China are you suggesting that if they were made in Japan that they would be superior?
  5. Hergan and I have known each other for several years and I respect his opinion regarding how well WWL-1/1B works with the Sony FE 28-60mm. It is a very compelling kit because it can also be used with closeup lenses like the CMC-1/2. With cameras like A7s 12MP and A7 IV 24MP I agree that you would be hard pressed to see a large difference V. WACP-1. With higher res cameras like A7R IV 61MP and A-1 50MP the gap begins to widen especially at the 28mm 130 degree end of the lens. I also think 121 missed the part of the Edward Lai interview where he described the Sony 28-60 "kit" lens performance as being I believe the word he used as astounding and explained that mass production reduces cost but not always quality. Just to assume that a "kit" lens is always going to be low quality is wrong.
  6. Hi Larry, First the new Nikon 17-28 F/2.8 like the Nikon 28-75 F/2.8 and the 70-180 F/2.8 on the recent roadmap all appear to be the Tamron lenses designed for Sony with the Nikon mount and Nikon outside sugar coating. If you look the optical design is the same as the Tamron's. If you go to the back issues of UWPMAG.com issue #119 has my review of the Tamron. It is a quite good lens especially with the S&S correction lens. Since the lens has a 67mm filter thread I used the S&S 72mm with a 67m to 72mm steppe ring. Not sure your 82mm S&S would work well at 67mm with a stepup ring. I used the 17-28 with 180 & 230mm domes with best results with 230mm. I used the 14-30mm with the 82mm S&S and got lousy results with anything in the 180 to 200mm range, you need 230mm. As noted above you can use the 14-30 at 17 so not sure you would see much upside to a second lens. I have all three of the Tamron lenses for travel photos. They all take the same 67mm filters and cover an excellent range of coverage at about 2/3 the cost of the F/2.8 Sony lenses in the same range.
  7. I reviewed this system in issue #122 for uwpmag.com which can be found in the free back issues at the top of the home page. It is a terrific little system, I had the 14-42 with the AOI UWL-09 for the review along with a macro lens. I have used 8mm fisheye lenses with 4/3 and M4/3 systems for years and the zoom with a wet lens like UWL-09 of WWL-1B is the most versatile choice especially for pelagic's. With the 8mm you need to be very close for best results.
  8. Also remember that to use the 8mm circular fisheye end of the Canon lens the dome shade needs to be removed or if will vignette in the image. I don't remember if you can do this with the 8.5 port.
  9. Nauticam has now updated the port charts for the 16-35 PZ lens lens with zoom gear SFE 1635-Z. Best results (*) are with the N120 35/ 35 II extension and the 250mm dome, cam also be used with 180mm 8.5" and 230mm. I was pleasantly surprised to see that because of the smaller size of this lens can be used with WACP-1. This requires the N120 10/10 II extension and zoom through from 28 to 35 that gives you 130 to 109 degrees of coverage. All other 16-35's from Sony and I believe all other manufactures only work with the WACP-2 but with fuller zoom through.
  10. Several differences between WWL-1B and WACP-C. First the WWL-1 contacts the water both at the front and rear, while the WACP-C mounts directly over the camera lens and only requires a port extension rather than a dedicated port with a port window. The rear element on the WACP-C is much larger than on the WWL. The WACP-C is about a pound lighter than a 230mm dome port. Both WWL and WACP's work with the outstanding 28-60 zoom.
  11. This is WACP-C on the Nauticam NA-A1 housing for Sony A-1. As advertised it fills the gap size wise between the WWL-1B and WACP-1. For me the weight and size difference is noticeable over WACP-1. The big difference for me is better overall image quality at wider apertures over dome ports, a wider and longer AOV over any lens in a dome and price. The WACP-C weights almost a pound less than the typical 230mm glass port, uses a smaller port extension for the Sony 28-60mm zoom and covers a range from 130 degrees to 69 degrees. If you have not seen the latest Wetpixel interview with Edward Lai he mentions using the Sony FE 28-60mm lens and that they were "astonished" at how good the lens is. He also said that because it is so small it can be used with WWL-1, WACP-C and WACP-1. If you do the math I think the WACP-C makes much more sense than buying an expensive F/2.8 or F/4 zoom, then adding the S&S correction lens and a 230mm port to attempt to get better corners.
  12. dreifish, You need to go back and read the captions for the photos I posted because you kind of proved the point regarding barrel distortion. This photo was taken with the Nikon Z6 and the Nikon 8-15mm FF fisheye at 15mm so it is a fisheye photo and it does have more barrel distortion than the ones taken with WWL-1, WACP-1 and WACP-2.
  13. The testing of the new Sony FE PZ 16-35mm has been done with the Marelux housing for the A7 IV and the Nauticam housing for the Sony A1. With both cameras I had the power zoom set to the wide end of the lens on the OK button and zoom in on the down arrow button. I did wide tests with and without the S&S conversion lens (now $600.00). Both housings are well built and the controls are well placed with or without gloves. What should not be overlooked are the outstanding Nauticam water contact optics that can be used with the Sony FE 20-60mm lens which is excellent for its cost. Cost wise the PZ 16-35 and S&S lens will cost around $1800.00 and the 230mm dome will cost in the $2276.00 to $2439.00 , port extension around $270.00 for a total cost from $4346.00 to $4509.00 The 28-60 with gear cost around $566.00/$681.00 depending on brand. The WWL-1B with bayonet adapter and port runs from $2087.00 to $2224.00. Total $2653 to $2905.00. If you chose the new Nauticam WACP-C the cost is $3283.00 plus the N100 30mm port extension $413.00 and lens with gear 681.00 for a total of $4377.00. Both of these combinations are going to have better overall image quality and corner sharpness at like F/numbers than the $4346 to $4509 packages. If you remove the S&S lens and go with the 230mm or smaller dome port the differences will be even more noticeable. Photo is the Marelux SonyMX-A7 IV housing with the 16-35 PZ lens and the S&S lens mounted.
  14. The compatibility of the 18-45mm with both the WWL-1B, WACP-C and several closeup lenses like the CMC-1/2 is excellent. According to the well respected PD Review the auto focus system is the same as the one in the less expensive R10 not the R3. It has subject recognition modes similar to the R3 but that is a completely different thing.
  15. Actually the Sony A1 would be the better choice because of its speed. The A7 IV uses the A1 AF system but because it does not have the stacked sensor system it is a bit slower. The A7r IV lags behind both in AF speed. I always seem to catch hell over talking about future products but it is pretty common knowledge that Sony will announce the A7R V in the next few months. I expect this camera will be high resolution with the faster AF speeds. Any of these cameras will AF well for wide lenses but for macro AF the A1 and A7 IV are quicker.
