    machan what is the best CMOS or CCD..??
    what are the differences between these?

    By best you mean image quality? Then the sensor type alone ain't going to answer your question. There is a lot more goes in to image quality than just image sensor. Consider lens quality, Image processor, manufacture technology/quality...etc.

    To find out differences simply Google "CMOS vs CCD". You will find hundreds,if not thousand similar discussions.

    Currently i have a 18-105mm vr lens..
    And i have seen on youtube that some people use something like a piece of tinted glass as a filter..:confused:

    watch this video then you will get what im saying :yes:

    For Nikkor 18-105mm you need to find 67mm filter.

    In that they are using Cokin filter holder and 'square/rectangular' filters They are normally cheaper than 'screw-in' filters and let you use same set of filters by changing just the holder. Also it helps to avoid vignetting on wide angle lenses.


    This is a general description for the Cokin P series filters. Here we explain a bit about the system and how it works.

    About Cokin filters:
    The COKIN CREATIVE FILTER SYSTEM contains a huge range of filters in many types, including; colour correction, special effects, black and white, polarising, neutral density and more...

    COKIN filters use the most advanced technologies. Many in the range are made from organic glass, which is shock proof, resistant to abrasion, and meets all necessary optical and chemical requirements. Others are made from high quality optical resin, designed to be flaw-free and of the best optical quality.

    The COKIN SYSTEM is designed for all photographers, amateur as well as professional. It is particularly quick to use and provides an economical way of building a collection of useful filters.

    For shorter focal lengths between 20-24mm or 28mm, as well as for wide angle zooms (24-50mm, 28-85mm, 35-135mm), the large P series filters are strongly recommended. The P series is available to fit filter thread diameters from 48mm to 82mm, and eliminates vignetting (dark edges).

    Why 'square/rectangular' filters, as opposed to "screw-in"?

    Square filter systems are particularly good value if you are likely to be investing in a number of different filters. They tend to be cheaper than "screw-in" filters, as you're not paying for a threaded ring every time, just the filter itself.
    They are also quicker to use, as you simply slip them in and out of the holder as required, rather than having to screw them in and out (they're held in place by a light spring action).
    The square/rectangle filter system offers a more convenient way to use multiple filters (up to 4 at a time), compared to screw-in systems.
    Some people find the bulk of the filter holder can be annoying, especially if you're trying to fit the camera into a small holster or ever-ready case.
    Although protective filters such as UV and Skylight are available in the Cokin series, some people prefer to use screw-in filters for protecting their lenses, as they are less bulky and easier to leave permanently in place.
