  1. Below is a geeky table I drew up with my preferred suits across a variety of temperatures. I'd be interested to hear what other people make of it...


    27-30ºC (81-86ºF) 1mm skin, (or just a dash of Aveda behind the ears)

    24-27ºC (75-81ºF) 3mm

    23-25ºC (73-77ºF) 5mm (using hood on lower range)

    18-23ºC (64-73ºF) 7mm

    minus 1-18ºC (29-64ºF) drysuit, variety of undersuits

    A distinct problem is that my table is shifted as follows:


    27-30ºC (81-86ºF) 7mm full + 5mm vest

    24-27ºC (75-81ºF) 7mm full + 5mm vest (+ 5mm hood)

    7-25ºC (45-77ºF) Drysuit, variety of undersuits

    0-7ºC (32-45ºF) Personal heater? :lol:


    The only time I can feasibly use 3mm neoprene is LensCoats! :)

  2. Don't you expect to have a lot of difficulty with focus with super macro if the subject moves at all? Possibly a DX format like the D90 may be more forgiving.

    I don't expect to have any difficulty - I'm not buying a copy! :)


    I think it may take some practice for those that don't shoot a lot of manual-focus macro, but it's certainly a current method for underwater photographers.

  3. It appears I view the camera with a more positive outlook than most - the conclusion I came to, along with a few others at DEMA, was that the 5DII may very well open the door to capturing behavioral traits of a variety of super-macro species. While typical camcorders are limited by the amount of stackable diopters, it's not unthinkable to quickly throw a 2x teleconverter (or more!) on a standard macro lens with the 5DII and use a manual focus gear as one normally would. Granted, light will be at a premium, but no one expected it to be easy! :)

  4. James, you can use the same argument for Canon 1DSMKIII vs it's own 5DMkII, clearly both companies are targeting these top end cameras to professionals who are prepared to spend the money for the 'very best' that money can buy. Clearly the D3x is placed to compete with the 1DSMkIII

    Remember that the 5D Mark II is releasing over a year after the 1Ds Mark III was introduced - a time when thoughts of the 5D II were internet conjecture, smoke and mirror rumors. And at $2699 (with an improved sensor no less!), it's causing a downturn in the prices of the 1Ds, as more people are moving to buy the 5D II than the 1Ds III. The 5D II is an excellent bargain, with the downfalls of slow AF speed, longer mirror blackout, and similar.


    If the D3x were released within a few months of the 1Ds III, would we be having this discussion? Unlikely. But introduction at the same price point over a year later is alarming...

  5. Hey Bruce -


    I'm planning to use the new mark II version in a less-than-forgiving environment (not just underwater! :uwphotog:) that leads me to appreciate the small added protection of weather-sealing. The upgrade should have improved corner sharpness - I'll be sure to provide my impressions if I do get my hands on a copy.


    More to follow on the less-than-forgiving environment in a month or two :fishblue:.

  6. Hi all - I'm looking for the new Canon 24mm f/1.4L II from a US authorized dealer (preferably not in California) at list price. Details are sparse about the product's release and arrival (especially from the larger distributors), and I'll need it for a trip on December 16.


    Shoot me a PM if you think you can help. Thanks! :uwphotog:
