    Default 0.45x & 2.5x lens filter; Which has heavier abberations? Eg. softness, CA

    Dear All,
    i'm posting here hoping to find user opinion on such filters. i'm actually using an SLR and have a 28mm and an 85mm. Thought of adding such filters ad-hoc for that occasional shot while using a prime lens.

    For eg. i'll bring a 2.5x if i'm anticipating more use of 28mm, or a 0.45x if i'm carrying an 85mm. Not too keen on zoom lenses due to smaller aperture.

    Thanks in advance for any inputs.

    not keen on zoom becos of smaller aperture, but you want to drop some quality for that little more zoom/wideness...
    aperture is nothing without image quality

    anyway, my question to your ans is NIL, we don even know what TC/WC you talking about.

    Dear ALL,

    any better 2x to 3x conversion lens/filter to recommend?

    Filter thread is 58mm.

    Thanks.
