  1. I have been with my A7rII for a month and two. DP review has just published their review I believe A7rII is the closest thing to replace an FF underwater dSLR. If you can use A7RII properly and get used to its AF system, you can save a lot of weight while traveling. However, if weight saving is not a priority, a conventional dSLR like D810 or 5Ds may be more rewarding than this small camera.


  2. I have unfortunately been struggling for a much longer time. I have Nex6, A6000, A7, A7r and A7rII. A7rII is the closest thing to a dSLR. Provided the weight saving and money saving is significant, I stand strongly at the DSLR side for a better investment. This is because of the short battery life and (still) slower AF acquisition comparing my A7r to my own D800 and 5D3. The cost of owning a housing along with ports is almost the same...or even worse as discount for housings for D800/5D3 is huge.


  3. Dear David
    I noticed one version actually takes four AA batteries and I started to wonder, if AAs are better than LiOn batteries. For one thing I am very sure that AAs work wonderfully for my Inon strobes but for video light, I strongly have doubt because of the working voltage and other physical properties.


  4. At the edge of my Nauticam A6K housing purchasing, I had unfortunately some heart problems. At that time, local dive shops are all persuading me to buy other dSLR housings instead of A6k because Sony housings are not available but dSLR housings had been always there.

    I had to give up the ideas of using heavy housings and instead, we, a group of three A6k housings from Meikon.

    Newer housings from Meikon like this one look and feel much better than their early products. Build quality is much better with a leak detector. However, the fixed port only accommodate 16-50 and 30f1.8. Their measurement before I placed my order suggested the port being compatible with 30 macro and it turned out to be wrong.
