  1. The A6400 is an excellent camera and a great choice for U/W photography. Just named DPreviews best camera under $1000.00 because of its great image quality, stellar auto focus and tracking system. I reviewed the camera for issue #108 of underwater photography magazine, uwpmag.com using an Ikelite housing. The article is a free PDF download you can find in the back issues. You can PM me if you have any additional questions after reading the article.
  2. Longbord 1 please read this, several miss leading responses are made above. First the Ikelite housing for the Canon SL2 (and SL1 & SL3) supports the DLM port system not the DL port system. So all of the observations by Chris would not be relevant. Only the DL port system includes the Compact 8' port which is much different than the DLM 6" port. The DL Compact eight inch port is excellent when paired with the Canon 8-15mm Fisheye on a full frame camera, see my review of the Canon EOS R in back issue #106 of uwpmag.com. This is a free PDF download and the review was done with the Ikelite housing and Compact 8' dome. Because your camera has an APS-C and not a full frame sensor the 8-15mm zoom is a large expense unless you intend to move to full frame. The Tokina 10-17mm Fisheye zoom also has problems with zoom range and vignetting with your housing and port selection. J-S comments reference the Sigma 15mm Fisheye with the five inch Precision dome on a full frame camera. The Precision port and the Ikelite port DO NOT support the discontinued Canon 15mm fisheye because of the large difference in minimum focus distance between the two lenses. The Sigma focuses to around 6.5cm while the Canon is 20cm this makes a huge difference when focusing on the virtual image created by the port. The fact that the Canon 15mm works in your current system does not make it ideal by any means. I would be more inclined to invest in a new lens rather than a new port.
  3. My mistake on current ZEN 170mm domes the dome shade blades are removable. So if you already own that port and can remove the shade blades you would have an advantage for splits. Would not be my choice for any other full frame lens other than fisheye.
  4. Please Read because some of the information above is a bit incorrect. First the Sony A7 line of housings has an N-100 100mm port mount not N-85 so any comparisons are not valid. Using the Nauticam N100 to N120 35.5mm port adapter allows you to use N-120 ports and in the case of the Canon 8-15mm Fisheye the metabones adapter extends to the edge of the port adapter and then you use the Nauticam Canon port charts to find the extension for the 8-15 zoom. The proper extension for the 8-15 zoom is the N-120 30mm for the 18811 140mm fisheye port with removable shade and 30mm for the Nauticam fisheye port II and 30mm for the ZEN 230mm. Both have dome shades that can be removed for use at the extreme 8mm end of the lens. Be aware a 140mm port is made that does not have the removable shade. Zen also makes a 100mm with and without removable shade. The ZEN DP-100-N120-CR (For removable) would be the proper dome. The Zen 170mm and Nauticam 180mm ports ARE NOT fisheye ports and DO NOT have removable dome shades, so the 8mm end of the lens would be useless unless you crop out a good deal of the frame. I have used all three port sizes extensively and as you would expect the larger the port the better the image quality in the corners with apples to apples settings. I would agree that the 230mm dome is a bitch to travel with but I have managed to keep my carry-on roller bag to under 12kg by putting the housing without grips, lenses and bodies into my "computer" second carry-on bag. The larger upside to the Nauticam/Zen 230mm (I own the ZEN) beyond the obivious over/under upside is that the230mm port can be used with the Sony 12-24 zoom, 16-35 F/2.8 & F/4, Zeiss 18mm and more by using 20mm, 30mm and 40mm extensions.
  5. As Taxi has said the Sony FE 90mm F/2.8 is outstanding for any Sony E mount camera and on the APS-C is equal to 135mm on 35mm size sensor. I would also consider the excellent E-mount Zeiss 50mm F/2.8 macro which is made for APS-C sensor Sony cameras. I just used this lens for a review in the current issue of Underwater Photography magazine uwpmag.com with the new Sony A6400 and Ikelite housing. The Zeiss 50 macro gives a 75mm 31 degree AOV v. an 18 degree AOV with the 90mm. Bot angles of view are very useful for macro with the 90mm being better for super macro with add-on closeup lenses. The auto focus on the A6400 is way ahead of A6300/A6500 in speed and accuracy for both lenses.
  6. Answer to World.explorer questions. Going to the back issues in uwpmag.com again, a free PDF download I have the following reviews. Issue #64 Pana 8mm N-4.33, #77 EM-1 review with P-8mm and Zen 100, #93 Canon 8-15mm with Zen-100 and #97 Oly-8mm with N-140. The reason I prefer the Nauticam 4.33 and 140mm for the 8mm's (P & O) is because they also work very well with the outstanding Olympus 12mm F/2 a favorite lens of mine for models and candid portraiture. I have attached two photos using the 12mm.
  7. I reviewed both the Kraken (Weefine) 1000 and 3000 ring lights in issue #101 at uwpmag.com. I think that most of the questions ask above are answered in my review of both light. Find the review on the front page of the magazine in the back issues section, it is a Free PDF download. Happy to answer any followup questions.
  8. Not to labor the point but mirrorless, DSLR or SLR film camera makes no difference. The Canon 11-24 F/4L on DSLR focuses to the same 28cm as the Sony 12-24mm F/4. The upside to mirrorless is that the Canon lens on FF DSLR requires the 250mm port for best results while the Sony lens with the 230mm port has equal or better corner sharpness. I would agree that using really old film ZOOM lenses that only focus to 18 or 20 inches will cause a problem because they need a +2 to +4 closeup lens to focus which then causes an above water problem, modern DSLR lenses or even older fixed focus lenses work fine for splits on DSLR or film. The attached was taken with a Nikonos RS a 35mm (so called full frame) film camera and an 18mm lens with eight inch dome.
  9. The auto focus on the A6400 is truly remarkable for a camera at this price point and beats many cameras in the over $3000.00 price range. I also agree that AF speed and accuracy in U/W photography is much more important than IBIS. The rest of the article is a free PDF download.
  10. To address Vagabond's original question about shooting the Olympus 8mm F/1.8 with a large port I have attached a few images using first the 8mm with the Zen Underwater 200mm port. You can see with the large group photo the water line will curve upwards or downwards when the lens is above or below the centerline of the photo. Just under the surface the model on the rights arm is distorted because of the fisheye even with the large dome port. For most applications I prefer the 8mm with the Nauticam 140mm port with the 17mm extension. I have also used the ZEN 100mm port with the lens. With the Olympus 7-14mm at 7mm and the Zen 200mm dome you get a much straighter water line and as you can see in the photo of Roman sitting on the steps, the lines of the rails and deck are very straight where as with a fisheye they would be distorted. Regarding Interceptor121's comment "on full frame rectilinear lenses cant focus properly on splits" not sure how you came to this conclusion and I will offer these model photos taken with the Sony FE 12-24mm F/4 lens at 24mm with Sony A7R III as rectilinear examples. Not only could the lens focus above or bellow water I was also able to use Sony's excellent EYE auto focus for focusing on the models eyes. These were taken with the Zen 230mm port which is the very best match for the lens. As a sidebar I have the Olympus 8mm, Nauticam 140mm port for the lens and the required 17mm extension all in mint condition for sale if anyone is interested.
  11. Well done Bill, your brightness values seem to mimic the guide number values published by the manufactures, with Inon rating the Z-330 at GN33 and Sea & Sea rating the D2J at GN-32. At the same time the brightness values are hardly apples to apples. The over 400 value for the S&S is for the strobe which has a beam angle of 80 X 80 degrees while the Z330 has a 110 X 110 beam angle. When the 110 degree diffuser is added to the S&S the brightness value drops to under 150. Using this logic it would stand to reason that if you reduced the beam angle of the Z330 strobes to 80 degrees the brightness value would jumpy 250 or close to 700. Regarding diffusers the S&S 100 and 110 diffusers are designed to widen the beam angle. The Inon strobe dome filters are not designed to widen the beam they are designed for two reasons, to reduce the out put of light by up to four stops and too change the color temperature of the light output. So again if you compare the S&S with the 110 diffuser for 110 beam angle and the Inon -0.3 dome filter with the same 110 beam angle the brightness value for the Inon Z330 is 100 points higher. I am pointing these issues out not because I have an issue with the work Bill has put in I am very well aware of how time consuming doing these tests can be. I just think it needs to be pointed out because these two strobes are in the same price ranged but not comparable apples to apples.
  12. I would be happy to answer to answer your question Rick. First of all understand that I have done over 75 articles for uwpmag.com,most on new equipment. The equipment I am reviewing in most cases is supplied to me and then returned to the manufacture. As a result I stick to reviewing the equipment I actually have in hand like the three lenses I used for this review. I am not in a position to own the twenty or so lenses supported for this camera by Ikelite. Since I don't own the Nauticam WWL-1 or the UWL-09F this would not be a lenses that I would be reviewing with this equipment. I have many times suggested that people in these forum consult the manufactures port charts for additional information on compatibility. So this is how that would have worked out the Nauticam WWL-1 supports two Sony lenses the Sony E16-50 power zoom and the Sigma 19mm F/2.9 DN. On the Ikelite port charts you will see that the Sony 16-50 PZ and 18-55 are only supported by dome ports, not flat ports and the Signs 19mm is not supported at all. Fantasea has just announced a housing for the Sony A6400 which probably does support some of their wet wide lenses.
  13. I have done a review of the new Sony A6400 APS-C camera which has all of the new AF features for the issue of uwpmag.com which posted today. This camera has the best auto focus for any APS-C camera I have used mirrorless or DSLR period. Regarding the animal eye AF please read the review for answers regarding which AF features worked best underwater for me. You may also want to look at A6400 review at DPReview regarding the auto focus in the concussing section. They place it as one of the best of all cameras at any price range.
  14. If I understand your question correctly the WWL-1 does not work with Nikon DX or full frame, it also does not work with any Canon other the M series. This may change going forward with Canon and Nikon FF mirrorless like EOS R and Z6/7 but not at this time. The WWL-1 will work with Sony E (APS-C) using the Power Zoom 16-50mm and the Sigma 19mm F/2.8 DN A. You can find the current port charts at nauticam.com, find the WWL-1 and then look for the port charts.
