Thread: Need help - Landscape Shoot looks blur after adding UV filter

    Default Need help - Landscape Shoot looks blur after adding UV filter

    Hi guys,

    Juz bought a tamron 18-200 recently with a UV filter attached. Attempt to shoot the MBS and the Helix and realised most of my shots are blur... Need some advises... What are the causes of the blur pictures? Shaking hands? or UV filters?

    Sample photos as below:

    Photo 1


    Photo 2

    Hi! it's normal that the image quality will decrease once you introduce another piece of glass in your lens.
    When adding a filter it is imperative to consider the type (coating and quality) of the filter.
    Great photography are gained not thru purchases, instead it is acquired thru practice

    Ops... I am using Emolux UV filter for the lens... I guess the filter must be of inferior quality since it is mentioned in the following thread to be avoided at all cost...

    So how to really choose a good UV filter? their est. cost? My intention is to protect the lens only...

    the best way is to use the same setting that u took the photo without the uv filter and try it....
    by the way what is your setting for taking the photo., focal length

    It's good that we have your exif info. There should be no handshake blur in the pics since your shutter speed is more than high enough to avoid that. So it probably just image degradation from the low quality filter, and poorer image quality 'cos you were using the lens wide open (or very close to wide open). For shooting landscapes, usually you want to stop down the lens to obtain optimal sharpness across the frame. And superzooms really don't tend to perform well wide open, you need to stop down by at least 2 stops (around f8) before the image quality becomes good.

    To find out how much your filter is affecting you, just do a trial with and without filter at home, shooting out of your window.
    My photos - see just some or all of it =)

    Just a thought.
    You shot at F4 - F4.5?
    Maybe you can try smaller aperture like F9.

    f/4 is not so good for such wide shots..

    There is a also purple color cast in the photos.
    Avoid using the (poor) filters.
    Lens hood can be used to protect the lens too.

    Emolux is not a good filter brand.

    I think setting iso to 100 will have to disable the highlight correction if not the lowest iso we can go with highlight correction on is at 200.

    The answer is your aperture is wide. For landscape go smaller. From F8-F16.

    As for Filters, go for some better ones. Hoya,B+W. but prepare to pay the price. thats all. Some use it some dont. as for me, I dont. as long as there is hood should be fine.

    your photo looks 18% grey to me, maybe u shot this on a cloudy/sunny day with auto WB.
    sharing some of my settings to shoot day landscape.
    Aperture values to f8-f11.
    Custom WB with gray card for RAW, white card for jpeg. If i feel lazy to Custom WB, i use the closest WB to suit the light. eg tungsten WB for shooting under tungsten light. cloudy WB for cloudy day
    Colour can set Vibrant or Bright mode.
    I leave my filter on in day shoot but night shoot all filter is off (to prevent ghosting)
    I use a mixture of Rodenstock, Marumi, Kenko Pro1D or Hoya HMC filters.

    Seems to be a combination of a wide aperture, wrong WB and a poor filter. Landscape should be between f8-f16 and I think ISO can go up to 400 to get a good shutter speed. WB should be set to cloudy for that shot and please lose the filter unless you get a good one.

    I'm using a marumi MC filter for just 1 lens and none for the rest of my lenses...mostly due to the size of the front element on that lens. Makes me nervous to have so much glass in front and no barrier to take nicks and such.

    Tripod will be best, Aperture f8 depending on the condition, remove the filter. Having a bad filter > good lens, no matter how good it is.

    With mulit-coated lenses, it's not really necessary to use UV filter. Can consider Hoya HD Protector if can bear with the cost.
