Low light + w/a = ???

7 posts
  1. Hi all,

     

    Just reading a few different forums and some of the above water users of the HC1 / A1E seem to think that a wide angle lens helps with the low light sensitivity of the CMOS sensor.. ;)

     

    Anyone have any Idea's on this..If its a possibility then how about the 0.7x sony wide angle on the camera before it goes in the housing. Anythings better than nowt.. :blink:

     

    Has anybody got an Idea of the time scale of the Amphibico 'EVO' for the A1E reaching our shores (UK) I need to start filming in Late JAN.. Other wise I'm hiring Doug Allans Z1E for a week..?? :(

     

    Also video light options..Greenforce vs Amphibico vs L&M vs Fa-mi. HID vs Halogen etc.. If there is already a thread please direct me ?? :P

  2. That's an interesting assertion. If there's any gain noise it should be present whether a WA is used or not. If anything, a WA lens that's not retrofocus will cause a drop in light.

    Also you may wish to look at the S&S HC1. Optically it is equivalent to the L&M (flat port) and it does have WB for the A1. And it is available now.

  3. Cheers Drew,

     

    I have never heard any reviews on S&S products..? What about additional lenses.? do they accept Fathom Imaging for instants.?? What about the after sales service etc..

  4. Only thing i can think of that would improve the quality is that the WA lets in more light and therefore the camera is using a higher f stop...

     

    Other than that....beats me!

     

    I think Drew made a sticky on lights at the top of the page didn't he?

    I don't use so no comment from me...

  5. Hi Mike,

     

    Yeah that was the general jist of the conversation on the other forums..?? But then again a wide angle on the housing would do the same???

     

    You don't use lights ???

  6. Ya, no lights. I have a set from the old days but they don't fit on the Gates or the Phenom, just little L&M guys with about 45 mins burn time. Used em a few times for a mandarinfish dive or 3.

     

    Mostly i shoot WA stuff and just rely on the manual WB. Sometimes lights would be nice for stuff under ledges etc or on the backside of a wall on the other side of the island from where the sun is (for near/far stuff) but lights are too freaking expensive so i don't bother.

    Still have about 2 years of payments left on the Phenom, never mind lights!

  7. From my impressions using the HC1 above water with a wide angle, I'd say the added glass negates the addtional light that's captured. I use a 0.38x wide.
