Even though the A7 R 5 is an incredibly good camera, if you have a limited budget I would consider which is the best way to go for underwater. I personally have had bad experiences with Seafrogs and have actually flooded one camera and almost flooded one camera. I would personally only consider the established durable housings: Isotta, Sea&Sea, Marelux, Nauticam, Ikelite. To build a system on a limited budget I would go more in the direction of A6700 in Nauticam. You can reuse a lot of your existing equipment. Read my A670 thread.

No. One of the envelops is gone.

I found the original cap very bulky under water, but very helpful at least while putting camera in&out of the housing. To ease the transport and to avoid loosing the expensive cap on the boat or in the water I used the leg of an old wetsuit, closed one end with cable ties, so I could pull it over the WACP-C like a sock. The additional benefit is keeping the lens wet/damp if it's not possible to rinse it immediately with freshwater.

Hi Romik, again a new bunch of informations to consider. Good news: I already own the lens and it was really much cheaper and came in "like new" conditions. I own the 1,4 TC (usually use it with the 200-600 if 600 is not enough). The 2,0 TC could be around 300.- but all the other things count. My personal experience with the long end of the 28-60 is better than yours... maybe quality varies... A lot to think about befor hitting the "buy"-button. Thanks a lot for all the input!

Hi Chris, I already found out that the Sony TC doesn’t fit into the MC11. So I actually changed my mind and decided to go without TC. My current perspective is to use the MC11 and the 140 dome from Nauticam.

As I have some more weeks until we head for our next trip, I‘ll definitely will do exactly that: putting lens, TC and MC11 in the housing and take some measurements. In fact I am quite sure not using the circular fisheye-end of the lens very often and therefore the 1,4 TC could be the best compromise. @Architeuthis I owned the 2,0 TC but sold it due to the weak optical performance…

Hi Wolfgang, hey, that’s helpful! 2 ½ weeks sounds great! Wish you the very best! The MC11 is at half the price of the Metabones and available on site here. That’s what makes me think about it. It’s also less bulky but if it doesn’t fit with the TC… So I am REALLY looking forward to your experiences!

Hi Chris, hi Adventurer, I feel almost uncomfortable stepping into this very technical discussion 😁. I have a practical question: while my WACP-C is on its way to Honkong for being repaired, I've had some silly ideas and have been able to buy a Canon 8-15 at a very reasonable price. I already own a 1.4TC from Sony and am now thinking of putting together an alternative setup for my A7IV in Nauticam - just in case I don't get my WACP-C back in time. Can I ask for your advice? Does the MC11 from Sigma fit the 1.4TC from Sony? Based on your comments above, the 140mm dome port seems to make the most sense? How much extension? Best Martin

Seacam doesn’t help? Nadia is selling one, I met her in Dominica. I think it‘s a reasonable price. https://www.facebook.com/share/12GQn7Nk3qn/?mibextid=wwXIfr

Ooooooo! YAFS has to be added to the abbreviation list!

So great! Being mostly alone with the whales. They are so interactive, great! Thanks to Franco and Sabrina

Anyone aware of the new (?)

I can understand the problem, but I see the difficulties more with night dives than with drift dives. I have an attachment similar to Dave Hicks', but it is no longer available new. I have now ordered one from Mares which I hope will work just as well. The advantage is that it can be used as a hand strap as well as for attaching to the BCD and with the stainless steel cable inside it should be strong enough. https://www.tradeinn.com/diveinn/de/mares-lanyard-stainless-steel-spiral-verlangerung/11461/p

Just FYI: Housing A6700 with acrylic dome: 2,4kg Housing A7IV with WACP-C: 5,2kg both including lanyard. 10-20/4 performed extremely well. I put zooming in on C3, zooming out on C2 and removed the zoom gear. If someone is interested in the Nauticam zoom gear for 10-20 - we'll never use it again.

And here a last one: you can see on the side of the whale, beginning at his mouth, a small structure like a line. That’s a tentacle from a deep-sea-squid. The rest of the squid is in his stomach.
