In Topic: Best Vacuum System for DSLR Housing

Another vote for Leak Sentinel. I was an early adopter soon after it came out. I can honestly say it is the most worthwhile add-on bit of kit I have ever bought. I use it with an Aquatica system and have upgraded to the Mk 4. Have never had any false positives; it has all operated flawlessly

 

Like others have commented above, Miso is brilliant in terms of service, assistance and advice - I needed a small spare part recently which he supplied FOC despite my unit being about five years old. Promptly too - two days from Slovenia to UK.. I am very impressed. And don't be put off by any thoughts of a language barrier - his written English is as good as most stuff you see on Wetpixel!


In Topic: Farming Tuna in the Mediterranean

12 October 2017 - 12:16 AM

As I recall, this method of "harvesting" bluefin tuna is the  tuna fishermen's response to the EU's limp-wristed attempts to protect the very seriously endangered population of this spectacular fish in the Mediterranean. I think they put a size limit on what could be landed or some such thing. Of course, there are few big mature tuna left so this system of rounding up the juveniles and fattening them up was developed. This has gone on for years and the EU's response.....zilch. But what would you expect from this inept organisation which supports and funds the boats used in overfishing  around the world, primarily by the enormous Spanish fleet.

 

I take objection to word "harvesting". Such a word implies that you put something back into the system or at least the item harvested is self-renewing. Neither occurs in this case, as ComeFromAway above explains, it is not sustainable and action should be taken to stop it.


In Topic: Aquatic Housing for Canon 5DSR

I love it and use it mainly for bird photography with big lenses. The ability to crop and the stunning detail are frankly amazing. I carry it on underwater trips primarily as a back up to my 5D3 should that go down (it never has). However have used it a few times mainly for wide angle and like it a lot. I think the sweet spot is around f8 so I don't think you gain much if anything in macro as the tighter apertures generally needed for close work result in pretty noticeable diffraction. This disappears once you downsize the result to similar size to that produced by a 5D3! A lot has been made of the lack of an AA filter causing moire. This seems overdone to me and have seen it occasionally in a mild form. It is easily got rid of in post-processing.

Yes it does - I have the same set up and use the housing for both bodies. Perfect fit, no adjustments or chuffing about required

I use a Vivid on my 5dmk3 Aquatica - and have done since they became available. Dead easy to fit, no wiggle and does the job perfectly
