1. The Forum Rules have undergone some minor changes and updates.  Please take the time to read them; it will only take a couple of minutes of your time. By doing so, you lessen the chance of incurring the wrath of the moderation team or making yourself look foolish to other members.

    90% of users posting adverts in the Sales forums need to be reminded to read the rules as their posts are wrong.  This is unnecessarily time-consuming and will no longer happen - if your advert doesn't follow the Sales Rules it will be deleted and you'll have to start all over again.

  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

  5. Postings on Politics, Religion & Controversial Off-Topic Material

    The majority of users do not want to read about these subjects and people have left the forum as a result of it – this is after all an 'Airgun' Forum. It’s all very well to say they don’t have to read it if they don't want to, but as most of us use the ‘New Posts’ button there is no easy way to avoid it.

    All AGF staff members are in favour of people being able to discuss what they want, but we have to draw the line somewhere if it is upsetting other users. We don’t want to read about these topics either.

    IMPORTANT- The discussion of politics and religion is no longer allowed anywhere on the forum (including the Adult section).  The only exception is if it's airgun related - they must be put in the Airgun Related Politics section..

    We will not tolerate bullying or personal attacks, racism or any other offensive 'isms'. we will remove these topics from the forum, we will not give you an area where you can abuse each other. We will not hesitate to ban offenders.

    What is the best watec deal out there? I'm prepared to spend around a hundred but want a lens as well.
    Most watecs are 1/2" and lens are massively different in price from 1/2 to a 1/3. What would happen if a 1/3 was to go on a 1/2 camera?

    Do people that use watecs generally do this? Because it's not cheap for a 1/2" lens

    A lens intended for a 1/3" sensor may well give poor results around the edges of the image as it is intended to cover a much smaller area than the 1/2" version. It is possible that the same, identical lens may be sold for both size sensors but there is no way of knowing. The smaller lens may give perfectly good results but, on the other hand, it may well not.
    The lens is a vital part of the system and it is not wise to skimp on it, particulalry if you are going to fit it to a high end camera like the watec.

    I have 16 mm 1/3 and 25mm 1/2 lenses for my watecs. Plus a few others lol:)

    The 25mm 1/2 is the one you want.

    The 16 mm 1/3 gathers a lot less light and does not fill the screen so well.
    Cheers Andy

    I could not see any on the bay at the moment ( using my phone) I have had my lenses a couple of years and the links are all dead.

    What you need to search for is:
    A 1/2" format, 25mm focal length, f1.2 C mount cctv lens.
    Cheers Andy

    Sorry I should have pointed out wwhat Andy said, the 1/2" format cameras do need the slightly longer focal length lens, 25mm is what I use and they give a full screen image. Those 5" screens are quite a good match for the resolution of the watec. At the moment I don't have links for any suitable lenses.
