    I was taught to put a UV filter in front of the lens of all but the
    cheapest cameras, but the camera I see sold now don't have that.
    Isn't it still a good idea, to protect the lens?



    The manual for the Sony DSC-H5 says it has an NTSC output for
    television.. This is analog. Since digiatl electronics use ATSC
    instead of NTSC, is this feature of the camera obsolete now when using
    a digital tv or digital video recorder? That would seem strange since
    I know the camera is digital and the recorder or tv is digital.
    Maybe the manual means that "EVEN if you have only NTSC it
    will work, and it goes without saying that it will work with ATSC
    which is digital."



    The manual keeps referring to a Memory Stick Duo card. Does this just
    mean an SD card? It looks like an SD card and it's marked 2G. But
    it says I cannot use a Memory Stick (What's that?), just a Memory
    Stick Duo!


    Thanks for any help you can give.

    There are two distinct schools of thought regarding additional glass in
    the light path.
    The first thing to consider is, an added UV filter for most digital
    photographic situations is not needed.

    There are those who strongly believe that any additional glass in the
    light path has the potential to deteriorate the image quality by the
    introduction of an additional reflecting surface. That reasonable
    protection of the exposed surface of the lens can be provided by a lens
    hood and a lens cap. Also most light surface scratches (and sometimes
    quite severe damage) does not perceptively effect the captured image.
    This school also believes that UV &/or "Skylight" filters sold as "lens
    protection" are unnecessary sales add-ons for the camera/lens vendor.
    Some of this group might use a high quality coated clear/neutral filter
    in extreme dust/sand/mud/snow conditions outside of a studio.

    Then there is the school which believes that the addition of a
    protective layer in front of the lens is good insurance. This group is
    divided into an educated group who will usually only buy higher quality
    clear or neutral filters with coatings optimized for use with digital
    cameras, and a less than knowledgeable group who are sold cheap poor
    quality filters by unscrupulous vendors to boost the bottom line.

    Some of those who use have had a demonstration horror story handy
    showing a shattered filter, telling how an expensive lens was saved.
    his is not necessarily valid as all it demonstrates is the filter was
    not able to resist that particular impact.

    So what you have is a mixed opinion. I occasionally use quality coated
    clear filters on some of my lenses, but most are usually without
    "protection". What you decide to do is entirely up to you.


    The Sony Memory Stick Duo card is a proprietary Sony memory card type.
    It is not a an SD card in any form. If it states you can only use a
    Memory Stick Duo they mean just that.

    I think it's very likely that Sony put a durable lens on the camera.
    Damage resulting from dirt and dust is more likely to be the ingress of
    dust onto the sensor and other components. A lens filter will help only
    if there is an air gap between the outer barrel and the front lens
    element. I haven't seen a big enough picture of the camera to assess
    it, but I would be very surprised if the lens had that fault.
    The video connector type(s) should be the clue - if has only an analog
    connector then it's analog output only. Is that so bad? Much of
    broadcast digital TV is old analog PAL/NTSC recordings that have been
    digitized then heavily compressed for transmission.
    Some people (including myself) call various plug-in memory devices
    "memory sticks", but this is incorrect. A "Memory Stick" is a specific
    type of removable storage device:

    The Web page has sections on "Memory Stick Duo" and "Memory Stick PRO
    Duo" cards.

    The manual says the camera uses memory stick duo and/or memory stick pro
    duo.
    The duo pro is a slightly shorter-length memory stick, but the same thing as
    a duo with a lil more speed and higher capacity. The 2G stands for two
    GBytes.
    SD cards have a different pin layout and are not compatible with your
    camera.
    The memory sticks from sony are dearer than sd cards though, but that's sony
    for you.

    As for the use of a uv filter, imo a photo taken through the lens of the
    sony H5 camera is not going to be noticably any different, but it does give
    you a great deal of protection from minor scratches which might help if you
    ever wish to resell the camera on ebay etc.,. Just make sure to use a
    quality filter though.

    Maybe there are, but only one school is totally misguided.
    It's not mixed opinion - the facts are easy to establish. It's all
    about psychology: a disposable camera is used to take pictures with no
    regard to its longevity. Very expensive kit (meaning that which would
    cause the purchaser serious grief to replace) is wrapped in cotton
    wool, even to the extent of lowering its performance, in the vein hope
    of preserving its value as a trade-in for the next "better" version.
    One either buys a product, writing off its cost at the moment of
    purchase, and makes full use of it until it expires or one is merely a
    serial renter who prioritises resale value over performance and purpose.

    As an example, I could order the new Nikon D4 on my credit card and
    make endless monthly repayments, but I'd hardly ever use it for fear of
    damaging its resale value. It would be much wiser to spend a lot less
    money on a collection of bodies and lenses that were individually
    expendable so I could concentrate on photography rather than resale
    value.

    Second-hand pro gear often shows considerable signs of wear and tear
    because the photographer earned far more money from using the kit than
    it cost in the first place. A molly coddling serial renter will forever
    remain a wannabe.

    Most people put a hundred times more thought into buying expensive
    consumer items than they put into selecting a partner for life - that's
    why the divorce rate is so much higher than the rate of returned goods.

    Depends on what you call a 'diposable camera' though. The guy has purchased
    a cheapish low-price camera from ebay as he couldn't afford a brand new one.
    I've been there...'nothing wrong with keeping the purchase in good condition
    in case you don't take to it and then re-sell it. Oh, I know what some pros
    and well-heeled amateurs can be like with their gear...'totally ruthless! :)
    Frankly, I would love to be able to afford such ruthlessness, but not this
    week I'm afraid. The Leica lens on his H5 is not going to be degraded just
    by adding a uv filter. Now if he had bought a Nik D3...'aye! It always
    amuses me too how photographers demonise their cameras, but when they put
    them on ebay, they go to great lengths to describe it using words like
    'pristine', 'immaculate', 'just a few scratches', 'loads of life left', etc
    etc. Oh, you do have a camera bag, yes? :)

    I meant the cheap use-once film cameras that were great for
    wet/dusty/sandy conditions - in situations which would probably ruin
    non weather sealed gear (i.e. most non-pro gear).
    Same here.
    A cheap filter will seriously degrade the H5 images. Even the very best
    filters have been demonstrated to create ghosting and flare - most
    noticeable in night shots containing bright lights.

    I've just found that the H5 includes a lens adapter with a 58 mm filter
    thread. I would suggest using a Hoya Pro1 Digital neutral filter. This
    range of filters aren't very expensive, but they seem to be very well
    designed and constructed; have extraordinarily low reflection; and are
    reputed to have good surface flatness, which is very important at the
    long end of the Sony zoom.

    <http://www.hoyafilter.com/products/hoya/pro1d-01.html>

    There's only one reason I won't use them: I bought an expensive 72 mm
    circular polarizer and didn't notice the case latch was broken until it
    popped open by itself sending the filter bouncing off into the
    distance. The filter didn't break, but it damaged the thread. I now use
    Nikon filters because they're very good and come with a virtually
    indestructible case.
    "Mint condition" aka "it's as desirable as a partially used mint candy."

    Cosmetically damaged gear is often sold at bargain prices and reputable
    dealers offer a guarantee with it. This is an option for owning items
    that one couldn't afford to buy new. A lens with minor abrasion on the
    front glass is definitely worth buying if the price is right.


    The bottom line about using protective filters should be based on facts
    rather than opinions:

    1. For best image quality, don't use a filter.

    2. Use one of the best neutral/clear filters available if the
    protection aspect makes the photographer feel more comfortable with
    using the camera gear. Consider removing the filter when taking shots
    in high contrast lighting.

    I normally use a lens hood because it keeps my fingers away from the
    glass and it's the first thing that gets hit when I'm moving around.

    3. In wet/dusty conditions, use a really cheap filter and either throw
    it away afterwards or try washing it with good quality soap and water.

    4. With most lenses, using a filter will not prevent the ingress of
    dust and fumes. Professional cleaning is the only remedy.
