Thanks for this in-depth video!
Glad it was helpful!
So the best is the 24-75 for all the dome ports??
24-70 is my go focal length on land. However if I were to shoot underwater, I would actually go for the 16-35 focal length as my first choice.
Also, I don’t think the 24-70 is compatible with all the dome ports. You might want to check their website 😁
hi bernard, is this a7siii port compatible with the a7iv as well? because when it comes to small rig cages, one cage is compatible for both cameras. tia
The ports are compatible across the different housings. :)
@@BernardLau1991 sorry man, i meant HOUSINGS not ports as the ports are just like lens hoods, for lack of a better term
@@misterpogiako oh yeah. the ports are the ones at the front, which are lenses and they are interchangeable. I am not too sure about the a7iv and the siii. The last time I spoke to the representative, he said a modification could be done but I think you better double check with them. Their customer service is quite responsive.
Whata the difference between acrylic / glass dome port?
I believe that glass would be more durable and won't get scratches so easily. I also think the image quality would be slightly better but I have not done a side by side comparison.
"Hello, thank you, your content has been very helpful to me as I was hesitant to buy a Seafrog housing. I also use a Sony a7III camera. After watching your video, I am confident that I will buy a SeaFrog. Is the dome you used made of acrylic or glass?
Thank you for your kind words. :) I am using the acrylic version as the glass one was not available back when I was making these videos.
I'm quite surprised that corner sharpness isn't mentioned at all. The image quality from a larger port will be significantly better. For example, the 16-35 f/2.8 with the 6 inch port turns corners into mush. For a full frame wide lens, you'd want even larger - 12 inches if possible. Unfortunately Seafrogs only do domes up to 8 inches. But not mentioning the IQ aspect specially at the edges and corners makes the review look incomplete.
Hi! Thanks for the valuable feedback. Yes in general I don't focus too much on pixel peeping and corner sharpness for most of my review videos but I can understand some consumers might want answers to that. I might provide an update to this video further down the road. Thanks again!
@@BernardLau1991 The issue is beyond pixel peeping though. For the A7iii with the 16-35 GM, even at f/8 or f/12, only the centre portion of the frame is usable. The corners and edges are just blurry. This is less of an issue with the higher MP cameras like the A7Riv or the A1, but with the A7iii, the croppability isn't much, so it can cause problems. It's not just the corners... the edges are blurry as well... only the centre 2/3rds of the image is in sharp focus. The 8 inch would improve this considerably.
For the 6 inch dome you discuss. Is that a dry dome when you do over/under shots? Or is there a film of liquid that you want to have on the portion that is out of the water?
Hi! Would it be alright for the 20mm 1.8 lens for the 6" dome port?
ooh. You will have to check their spec sheet to see if it does as I couldn't try them all. You can also email them and they are very responsive.
Do you know if you can disassemble the extension so you can use the dome with other lenses?
I don't think you can do that.
Hi Bernard do you still collaborate with Seafrogs? I tried your discount code but it didn't work.
I don't think the discount code will work anymore as it has been quite some time ago. :/
@@BernardLau1991 Yeah unfortunately :(
Hi, great video! 😁
I would like to buy the Tamron 20mm F2.8 or the Samyang 24mm F2.8. Do you think that with the standard port I'll have some vignetting?
Thank you for the support! Unfortunately, I do not have the answer and I think it is best to reach out to them directly for answers. Their support staff is very helpful and responsive!
@@BernardLau1991 thank you for your reply. Unfortunately they haven't tested these lenses. I'll try 💪
Do you know if the Sony full frame wide angle dome ports work for the Sony A6xxx underwater housing? Are all the ports interchangeable across all SeaFrogs Salted Lineunder water housing?
Hi! Unfortunately, I am not too sure as I have not used that system. You might want to check with seafrogs for an accurate answer 😁
@@BernardLau1991 Thanks for the response! Your videos are fantastic! I picked up a SeaFrogs Salted Line for my A6400 with the standard port but now I’m looking to get the 6” done and they’re difficult to find lol
@@DennisMeetsWorld Thanks for your kind words. :) I think they are interchangeable but best check with the experts. lol. Hope you find what you're looking for!
I checked the SeaFrogs website and they don't have the 4 inch dome .Is the 4 inch dome port the same as the 6 inch dome port for surfing. I have the 6 inch dome but if I use a small lens (short in length 80mm), wide angle like the Loxia 21 mm lens, I noticed vignetting as Len is far from the front of the port. I plan to get the Venus Laowa 9mm lens and use it with the 6 inch dome part but there might be more vignetting due to the wider lens. Not sure if the 4 mm will be better as it is shorter and the lens will be closer to the front of the dome and less vignetting>
I’m not sure if they still have it. You can always write in to check. The 4inch is def difference from the 6inch. Maybe they discontinued it?
And also ask them if the laowa lens is compatible with the port. 9mm is very wide. 🤔
Thank you for this review. Where did you find the 4" dome port? I cannot find it online unfortunately
It seems like they discontinued this product after a while.
@@BernardLau1991 that's unfortunate. I think it might have performed well with a fisheye lens
Great information! Thanks bunch!
Thanks for your support!
Hello Benard, I just had a quick question regarding lease compatibility. Do you know if the 8" dome port would be compatible with the Tamron 17-28mm 2.8? It says the 6" is but there isn't any mention of it in regards to the 8". It is to he housed with a Sony A7RIV. Sorry to be a menace, just can't find any information regarding it's compatibility.
Hi. I’m not too sure about that. I think it’s best to check with seafrogs directly as I don’t have that lens to test out. Maybe drop them a email. Their response is usually very prompt :)
Great video! What do you think about the SEL28F20 and SEL057FEC fisheye video setup with the FF 6" dome?
Are the lenses compatible with this housing? I'm not too sure haha. But the 6 inch dome is definitely a good choice :)
Compatible with a "minor" vignetting effect
@@johnboy4584 oh. will that vignetting effect happen on the 8 inch? I would avoid this combination if there would be vignetting but that also depends on how particular you are. Why don't you consider other lens options? haha
Nice Video! what is the best Dome Port for a6300 18-135mm????
For surfing shoots from water
Thank you! And sorry I don't have experience with that lens so it's hard for me to recommend. But from what I can imagine, the 8 inch would be good if it is compatible. :)
Hi Bernard.First of all thanks for the video, it was of great help. Please could you give me the compatibility link of the various ports. If I click on the link that you have put it sends me to the ports to buy, but I would like the table with all the various choices between objective and port, as you show in the video.
Hi Alessandro. Thanks for reaching out and your kind words. The link to the compatibility of various ports will be available in their website. Hope this helps :)
Hey man, another great Video. I can not find the document in your description though?
Hey 👋 try the one that says get your seafrogs housing here? If not it should be on their website. Hope that helps!
@@BernardLau1991 found it on their website but thanks Bernard :))
Thanks for that really, I'm trying yo understand the difference of image quality or field of view between a curved port and the flat one, especially when using the 16-35. Any feedback on that?
Hey! Tbh, I don’t have proper side by side comparisons, so I’m going to make some assumptions. I think having a dome port will cause the image to distort a bit as compared to a flat port. But tbh, I’m not particular about it so I don’t notice it. A flat port wont let you do the half in half out shots as Easily. So if you want to do that, you don’t have a choice but to go with dome ports.
Thank you @Bernardlau for your reply, greatly appreciated :-) if one day u think about selling your 4" dome for the A7s3 housing lemme know, meikon discontinued this product and I'm interested by it 😊
@@MaldavarFilms Oh man. Did they? I wonder what they did that. I'm supposed to bring it on a dive trip this weekend for it's first real world use. I haven't got a chance to use it since making this video haha
@@BernardLau1991 got it, enjoy!! :)
It should be fine at the longer focal length but at 16mm you will likely have significant distortion, its too wide for a flat port.
