    Anybody have opinions on Sony's DXC-M7 camera?

    Yes.

    Does that answer your question? I've tried to be as broad as
    possible to cover all the options!<g>

    Now, why don't you try being a bit more specific and maybe
    you'll get some sensible replies.

    I used them extensively in the 80's and early 90's.

    If your bass boat needs something to keep it from drifting down-current, the
    M-7 will be perfect with the addition of a length of chain.

    I'm only *slightly* exxagerating. It's too old, needs too much light, you will
    be forever futzing with calibrations... but at least it's not an M-3. For that
    I would recommend counseling.

    E-bay it to someone more gullible, use the money towards a more modern camera.
    The Canon lens for the M7 is worth more than the camera. The Fujinons, not so
    much.

    I concur. I just, thankfully, retired 2 of the 3000 models, part of the same
    design. Good riddance to bad rubbish. These were Sony's first CCD cameras
    and had enough problems to wish for Plumbicons back.

    I would be delighted to answer a specific question but "How long
    is a piece of string?" does not inspire a polite reply after a
    long day and a couple of glasses of wine.

    The M7 is a stand alone camera. You need a separate recorder,
    BVU150, VO8800, or BVW35, etc. The camera weighs about 8lbs +
    3lbs for the lens. With the portable recorder, it was considered
    a two man unit for ENG. It has a horizontal resolution of 700
    lines; minimum illumination 26 lux with F1.8, +18dB; 2,000 lux
    at F1.8; signal to noise ratio 60dB, etc., etc.

    I have both the Operating Instructions and the Service Manual
    here if you want to be more specific.

    I'm a BIG fan of Dinovision

    I believe that the M7 has the same optical Chips
    of the BVP-7, which is to say that if there are no dead
    pixels, and it actually still works, you might have something
    still useful... hose it into the deck of your choice

    Use it on shoots for cheapskate clients that want
    everything for cheap

    but bring some lights...

    You'll get little sympathy here. Derry gave you the answer you deserved
    with such a silly question. Msu guessed at what you would have asked if
    you had thought about it. Its hard to read your mind at this distance.

    Old School Cameras

    The older M7's have circuit cards inside that show signs of extreme rework,many parts tack soldered to the back of the card . These aren't repairs ! These left the factory that way ,seems Sony left some parts out when they built them . I feel sorry for the factory techs who had to rework these cards day after day ! Also ,the rubber handles get sticky and decompose,and leave sticky black goo on your hands. I have picked up one of these by the handle and had the rubber covering on the handle separate from the handle and stick to my hand . I had to use paint thinner to get the stuff off . If your camera is in good condition it can give a very good picture ,very few ordinary TV sets can do this camera justice .I like the M7 and DXC 3000 because of the flexibility ,you can use any recording device you prefer. What kills these cameras is heat ! Leave it in the back seat of your car on a hot day ,then turn it on and shoot pictures ,sooner or later ,fried camera! Most of the repairs I have done involve replacing swollen and burst capacitors .Most cameras I have worked on have damaged IR filters ,they are cemented and heat causes the filter to fog up . Leaving these on 24/7 only can shorten their lives . The M7 is a very quiet camera noise wise ,I have shot a decent picture with with the gain turned up and nothing but a desk lamp for light .I like the fact that it has Y/C-RGB-Composite output available . These can interface with modern S-video equipment . If you are trying to earn a living with your camera you should invest in a modern digital camera ,these old cameras are for hobby use only .

    Another use

    hello all...i know this is an old thread but here we go. I've obtained a couple of DXC-M7's for free. My idea was to use them for one of my professor's (I work at a university) projects recording growing crystals. Yes, I know, a fascinating subject. My plan is to hook it directly into a computer capture card and record the experiment (growing crystals). The scale/size of the crystal is rather small but not close to microscopic and the time could be up to an hour. My question is, do you think this is feasible? I also obtained a couple of BVP 5's for the same project not knowing which would be better. Any advice on the matter would be appreciated.

    Not a problem to bring this up (for me). FYI, I am STILL using three DXC 3000's (about 23 years old each) to shoot a church service each week. 132, hour long shows in the past 2+ years. On my first 20 or so shows one of the three cameras was a JVC 320 Plumbicon camera. The cable company's signal is so bad it doesn't matter what you start with - it's bad at the end.

    My question regards the fogged IR filters. Are they available anywhere? If not is it possible to remove the filter and then use a threaded IR filter on the front of the lense? Most of my DXC-3000's (I have six) still have decent filters. However, I just got three Ikegami 340's and the IR filters are fogged.

    Perhaps if they are glued together they can be separated and re-glued???

    Thanks, Tom

    there is a M7 in my gyrocam?

    I was reading the model # off my viewfinder on my Schwem gx-3 gyrocam and seems there is a M7 inside the can.... we can use an m7 manual if anyone has one here at the museum then! and.... if anyone has a MX-3 manual we would really be delighted...... we have combed the net to no avail.

    So, posting to this old thread again. Does anyone know if the DXC-M7 and DXC-3000 use the same extender card (for calibration / repair). We are a low-budget non-profit and have actually had reasonable luck with the DXC-3000 (we have 4 of them working) but just received a donation of some DXC-M7s and would like to migrate to that (for better light response etc.) if possible.

    (We are shooting on a semi-professional stage with a lot of lumens.)

    Of course a maintenance manual for the DXC-M7 would also be great.
