    H4D and field cameras battery source

    I've been looking into field cameras such as the Cambo wide WRS 1000, Alpha TC, Acra Swiss RM3D etc. These were to attach to my H4D digital capture unit, but the only source of power for this DB is the Hasselblad image bank, which was priced at $1995, but is also discontinued. The option of mounting the H4D DB on such a camera was tantamount to a purchase, but an image bank on a Alpha 12 TC seems negate the portability. Hasselblad doesn't mention this in its literature, unless I overlooked it. What power source are others using for these cameras specifically, hasselblad?

    I have used the following product with a firewire hub to provide power for my H3D II 39 on an Alpa TC.

    Essentially you power the FW hub with the battery and use a 400-800 cable or adapter from Granite digital to power the back.

    Works great....small pouch on belt or on tripod to hold the above...not as small as the Phase or Leaf variants but it works and is much less than changing systems.

    The Imagebank II system allows battery changes to run all day...look for one if you settle on the H4D 40 as a workable form....try the Tekkeon as an interim solution.

    NO ONE shoots landscapes without a large amount of stuff....a battery and cable will be the least of your concerns.

    Do you have any samples of the Alpha TC you can share?

    Thanks again.

    Most of my other posts have been culled in deference to storage issues on the forum.

    You can attach a battery to a Hasselblad 39Mpx back, and there is/will be a battery attachable to the 60Mpx.

    I've got a as-new imagebank II for sale in the FS section. I bought it to use it on a H4D-60 but retreated because of the long shipping delay of the H4D-60. It really is a rock-solid piece of equipment. Before that I tried the HD firewire plus from Hotwire digital which caused nothing but problems, after 20 mins it shut off because it couldn't power the back anymore.

    Apparently not all backs draw the same amount of power and this can cause problems with third party equipment. I was refunded the full price for the hd firewire plus.

    kidn regards

    Re: H4D and field cameras battery source

    After a long period of difficulty with interfacing my H3D50, I settled on the following:

    http://www.sonnettech.com/product/fw...esscard34.html
    This is a FW800 card, which is quite a bit faster than FW400. For tethered work (95% of what I do) I power the card from the Tekkeon (below) and the back from the card via the FW800 cable.

    http://www.tekkeon.com/products-mypowerall.html
    I prefer the MP3450i, which is stabilized and has a fixed voltage set by a dip switch. On some other units you have to select the voltage every time you turn them on - one of those annoying little tasks. Make sure to order the firewire socket adapter. This allows you to plug the battery directly into the back when you are not tethered. I use a second 3450 to power the Rollei shutter on the studio camera and can shoot for hours with this setup.

    The standard Hassy FW800 cable works fine for me.

    All of this is a pain in the field. Untethered, I generally tape the battery to the tripod, use a 6' fw800 cable, and just acquire to the memory card in the back. Of course, then I get home and find my aging eyes yielded very few keepers. Next time I take the computer so I can see what I am getting. Bob is right. No one shoots landscapes without lots of stuff. Perhaps you should give the TS adapter a try. A compromise, but convenient.
