    I have my new Tamron 18-250 lens running great with my Sony Alpha
    A-100 but I would like to buy a filter to protect the face of the
    lens. My question is what would be the best type of filter to get
    that could enhance the picture quality while protecting my lens?
    Circularizing Polarized? UV? Skylight? Nuetral? Would rather not
    have to swamp filters out as I really would just like to protect the
    lens but if I can get some benifit from it, then that's an added

    I mainly take outdoors nature shots in full or partial sunlight.
    Sometimes indoors with the built-in flash but not too often.

  2. UV or neutral has the least impact on colour.

    There will be no impact on colour if AWB is used or if shooting RAW, can be
    adjusted for in PP.

  4. Sony now offers a 'protector' filter on sonystyle shop pages. I use Hoya
    Pro 1 Digital UV. It must be a very slimline filter to avoid vignetting
    with that lens - standard 62mm thick rim filters are no use. Same goes
    if you want a pol. It must be a wide-angle type or thin rim.

  5. A lens cap is very very good at protecting the face of the
    lens, won't splinter and is much cheaper and stronger than
    any filter.

    A lens hood also improves the image quality (removing stray
    light), though at 18mm the lens hood will do nearly nothing
    for 100mm or more ... and be rather short.
    NONE. No filter improves the picture quality, they only
    degrade it (from practically unnoticable to "a lot".
    is a special kind of filter, eats a lot of light, and can in
    special situations help (making sky bluer and reducing or
    strengthening reflections --- but only if used correctly).
    Many people use it, though it's usually only needed for
    analog film, especially in the mountains.
    Has a slight impact on the colour, but your camera
    counteracts that with AWB, so nothing good comes from it.
    Neutral density filters just eat (lots of) light --- that's
    their function. If you want to shoot a flowing river with a 10
    minute exposure by day, that's what you use.

    There are special protection filters. Buy the most expensive
    one from a reliable dealer, they hurt the least. If you shoot
    where mud, water (especially salt water), sand or similar flies
    around and has a good chance to reach your lenses' front element,
    use it --- otherwise keep it off.
    For special effects a polarizing filter might help, but you gotta
    learn how to use it correctly, and it's no good as a protection,
    since unless you set it correctly (which takes time, depends on
    the camera position and the direction you shoot and more) it'll
    hurt a lot.

  6. Collapsible rubber lens hoods will effectively shade a range of focal
    lengths, and offer some shock protection against knocks. You can also
    push them right into window glass to cut out all reflections.

    Already using the hood that came with the Tamron and that works good
    unless doing extreme closeup work with the flash, then I get it's
    shadow but that's not often and not a big deal. I keep the lens cap
    on when not actively shooting but with the hood on it's a little tough
    to pop the cap off quick (have to reach up inside the hood and then
    find the two trigger latches), When we're off in the woods hiking and
    a deer blasts by or an eagle swoops nearby that few seconds to pop the
    lens cap off can make all the difference in the world in getting the
    shot. That's why I was thinking if I had a minimal impact filter to
    protect the actual face of the lens then I wouldn't be so hessitant to
    walk around without the lens cap on. Sounds like the 'protector'
    filter on sonystyle site might be the way to go. Or a slimline 62mm
    UV or nutral. I'll have to shop thru that and see.

    Was not looking at the filters to enhance the image as much as to
    protect the face of my lens.

    Thanks for the input!!!!

  8. Filters offer almost nothing to protect against a direct blow, although
    there are those who report the filter was shattered and the lens was
    safe on a direct hit to the center of the lens, - but, if the rim of the
    filter comes in sharp contact with something hard, it does nothing to
    reduce the shock to the camera body.

    A lens hood that's well made gives far better protection for my money.
    It can protect against side blow much better, gives some shock
    protection if droppen on the hood, and the hood, of course, has other
    photographic advantages.

  9. In these circumstances you will not have the camera in the bag,
    either, so it's round your neck or in your hand. In that case,
    what exactly do you fear to happen to your lens?
    Lens hood on, be a bit careful (as always), and that's it.
