    I have read before about this 50ft adapter for scopes so as to see clearly targets as close as 7m. Tried to google to find out more but all I could find was a Leupold 50ft adapter for one of their older scopes with a small objective. Much smaller than the 60 of the Nikko which is most commonly used in FT.

    Question is, are these 50ft adapters used only on small objective HFT scopes for 7m targets or are there other 50ft adapters that can be put on bigger objective scopes for FT?

    Or am I simply confusing things up? :eek::eek::eek:

    As you say there is only one size. To mount it on a larger scope you cut out the centre of the Butler Creek cover - very carefully as it is important that it is dead centre

    I've noticed before they seem to be quite rare and usually sell quickly, and I always though the 50ft in a Butler Creek looked Heath Robinson.

    Is the 50ft adaptor just a single lens in a threaded carrier? If so it should be quite easy to get the dioptre, have some lenses ground to that prescription and built into flip-ups, or even have some quality threaded flip-up adaptors made for certain popular scopes incorporating the lens into a cover. Baked or half baked?

    As Dave above will tell you (his wife works in optics), the diopter of the 50ft adapter is extremely shallow, and he hasn't been able to find a machine that can do it...

    But yes, if you could, you could ;) :)

    So for the moment we're stuck with the 50fts being mounted inside BC's et al.

    Oh right cheers Rob. My aunt is an ophthalmic optician but she's retiring later this year. Just out of interest, what is the dioptre?

    That seems to be quite a hectic job to do...........just have to start getting used to shooting 7m and 8m targets blurred if I get to go to the Hungary Worlds this year.

    Damn it, if I wanted to shoot blurry targets I could just have switched to shooting HFT in the first place :mad:

    Thanks for the feedback anyways guys.

    Drop the mag to 10 x, used to be 'just' in focus for me.

    Or try a flip up with a 7mm hole drilled in the centre.

    Will try to put the mag down to x10 and see what happens then but doubt the target will be anything but clear at 7m :mad::mad::mad:

    Who the hell shoots FT with targets as close as 7m!!! :eek::eek::eek::eek::eek:

    We're not sure about the diopter as it won't register on standard ophthalmic equipment but we believe it is about +0.125. Rich Chasemore has a different one which is clearly a single lens in a flip up mount, but nobody knows where it came from

    I wish I could get a simple answer as I would like to source a better one myself. I've pretty much given up with the Leopold ones. My Comp 40*45 will focus to 9m so if it's out of focus I call it 8m. I've only been caught out one - at Buckley Wood - where I shot at the black circle of misses rather than the kill zone

    Please let me know if you get any further with this

    Regards

    Dave

    Dave is it a single cap which has the lens attached to the front and the lens held in place with a silver clip,not like the twin set bulters. If so its the type I had from permier when they modded a vx3 to 20/50
    you can just make it out in the avatar

    It's a glass lens (cos it's chipped), and a silver ring.

    Always thought the minimum FT target distance shot in the UK and the rest of the WFTF countries (except Hungary) was 10m :eek::eek::eek:

    Seems like it's not!

    Such issues should be standardized in the WFTF core rules in my opinion..................

    Raise it with your WFTF rep :) Nothing can change if it's not discussed at that level.

    Yep, did so a couple of weeks ago as you had already suggested it on another post........remember? ;)

    I got a reply stating that this and other issues are to be discussed by WFTF reps and hopefully be standardized in WFTF Core Rules but to date I have had no reply and the FT Worlds are only a few months away :confused:

    BTW I am Malta's WFTF rep ;)
