  1. To add to Paul's thoughts, editors generally like to overlay text, captions, insets and such in corners. No one actually sees some of the corners, and again as Paul notes, readers look at the subject, not at the corners. I find it amusing that on 50% of photographs (wide angle), photographers obsess about the sharpness of corners. On the other 50% (macro) they obsess about Bokeh and a nice softness to everything other than the subject.
  2. Can anyone recommend similar that takes AA batteries (so I can remain standardised on rechargeable AA as far as possible)
  3. I haven't worked in a sauna, so this is interpolated from other experiences. Summary of my thoughts - some already covered above. A housed system will be heavy compared to a bare camera. Not such an issue on a tripod, but soon becomes tiring if hand-holding. You don't need pressure proof. Just moisture resistant. A compact such as a TG6 or an action cam / Go Pro may have good enough quality, be more convenient to work with, and be a lot cheaper than buying a housing (unless you already have a housed system) For a housed system, to minimise fogging inside, assemble in dry conditions. Add a small sachet of desiccant inside the housing. As already noted, unlikely to be an issue if its hotter outside. Leave the camera or housing in the operating environment for a few hours for temperature to equalize to cut down on internal or external fogging. Flat or dome port on a housing won't make a difference to focus in the air. You won't need any correction diopter on the lens for a dome.
  4. Writing from a position of complete ignorance about this lens, does it need a diopter inside a dome? That would be a few mm extra.
  5. You may be able to shoot macro with a good dive light.
  6. You only need the 1 bucket of fresh water for rinsing. You can put a lid on it and use it again day after day. The small accumulation of salt will be negligible. As for filling the bucket in the first place, if you can't spare enough to fill it once with clean water, consider reusing your wash water as long as you don't use too much soap.
  7. To get from Hurghada to Marsa Alam, there are more economical routes from town to town by staying clear of actual airport transfer busses. If you pick a dive center with bases in both towns, they will be motivated to advise. Many have staff cars or pickups shuttling back and forth. There will also be minibuses for locals from town to town. The down side is that such transport involves connections and works on local time, so you need slack in your schedule to avoid getting stressed.
  8. I used a ring of sticky back velcro. Just enough friction to catch on the gear from the housing.
  9. I have similar experience with Inon's. Over many years of abuse they have never needed repair, so I don't know about support. The only disadvantage is you need a PhD in Inon to understand the knobs and buttons. If buying fresh I could be tempted by Retras - the controls look a bit more obvious and they are shiny.
  10. Maybe its not just an equipment convenience. This may be an urban myth - the story I heard is that the old masters (artists), having to paint by daylight, would sit with the light coming over their left shoulder so their right hand (with the brush) did not shadow the painting. This had a knock-on effect for the light on the subject. We have been conditioned to appreciate that style of lighting. Everything since has been inherited from that. Even with a dual strobe setup, sometimes it is nice to dial the right down a bit or the left up a bit to create a little bit of direction to the light.
  11. A very good point. My wish is modified to "designing decent User Interface software that can work in a housing"
  12. The real improvement in digital cameras will come when the manufacturers start designing decent User Interface software. That could be done with existing hardware, it doesn't need dream hardware or new manufacturing. It could be done with existing cameras.
  13. Check the weight. They look as if they could be a bit heavy with all the strap mechanism as well as the foot pocket.
  14. When rolling off the boat, the objective is for my cylinder/back to hit the water first. I don't think I ever finish a lengthways roll once in the water. Stretch out and twist is always an easier maneuver. I only extend my arms as I hit the water, so my body goes down to arms length while my camera is level with the surface, then follows me at arms length. The rest depends on the dive plan. If the plan is to gather by the boat, I usually do a couple of quick kicks down backward and away to make sure some muppet doesn't roll on top of me or my camera. Then surface a body length or two away from the boat and wait, or swim to the grab line away from where others could roll or jump. If its a straight down and rendezvous on the seabed, I stretch and twist to face down and keep on kicking. A lateral force once underwater is negligible. Its a lateral force, or any force, at time of impact that I strive to avoid.
  15. When I need to roll or jump with a camera, I start with the camera close to me and as I hit the water push the camera upwards. I try to keep the back of the housing (and hence viewfinder) down and port upwards. I always have a lanyard attached. My theory is This reduces the speed the camera hits the water I create a hole in the water the camera follows me into Nothing on the camera bumps bits of my kit in the process No o-rings or joins are subject to a lateral force of water Whether the above is valid or just a rationalisation, I have never had a camera mishap doing such. On the other hand, I have come close to losing cameras when they are passed down from the boat.
