Not sure what the connection is, but Brentford Radio Control are at 5 Albany Parade, the address for Asahi Photo.

Their telephone number is 020 8560 6856; web site www.brentfordrc.com. Maybe they can throw some light on the Asahi Photo situation? (albeit tonight their website is down for maintenance)

i have a "3 Legged Thing " VYV Punks which folds to 40cm, comes with bag, has 1 leg that can be converted to mono pod, the ball head works well, supported my K5 + Sigma 170-500 with no problem, , will go down to a height 11cm from ground, it has a ballast hook to hang extra weight on if needed for stability, all in all have found it very good, made from aircraft grade magnesium alloy weighing in at 984g
Thanks for this. Looks very good, but more than I would want to pay for something that is only going to get very occasional use.

A belated thanks to Magicman, and a more timely thanks to benwood08 for your replies. I'm still not decided.

Struggling to remember the name, but there's a little device - Weiz cell? - that sits between the flash and the hot shoe and effectively reduces the trigger voltage reaching the camera whilst allowing the flash to operate in manual mode. Unfortunately this partially defeats the functionality of the flash, but I suspect a film era flash would only perform in TTL mode on a DSLR anyway.

Is there any play in your focus ring though, however slight (enough to make a little click when trying to rock it at the rear from side to side, without turning it)? I can also slide the corner of a sheet of writing/typing paper between the focus ring and lens barrel, though only by about 1/4 of an inch. Both these may be normal too, thought it better to check because my 30 year old Mitsuki 400mm is slightly better in this respect (though much worse in general build quality and image quality).
Yes, there is a little play, and click, but can't say I noticed either until you asked!
OK thanks again, looks like that's by design as well! It won't be a problem unless it gets worse, which now seems unlilkely. I hope it doesn't start to bug you now that you've noticed it!

Odd about your DFA 100 WR though, as mine has a firm stop at both extremeties of the focus ring.

Great image quality on the 300 incidentally, and it's made outdoor long-lens photography on dull afternoons like this one much more of a practical proposition.
When I said earlier, '..are exactly the same as yours', I should have said 'the way your's operate', i.e. stops each end of focus on the 100, no stops on the 300.

What I am asking is if these two points are by design, or if they indicate a sub-standard lens. Can anyone help? Thanks!
Re your point 2, quite normal. My DA*300 and DFA 100 WR are exactly the same.
Thanks, looks like 2. is by design then.

Faced with a similar situation a few years ago I bought a bridge-camera rather than take a DSLR + lenses. Agree that the IQ was slightly inferior, but had/have no regrets.

K5II vs. IIs.

IIs has no anti-aliasing filter; otherwise identical afaik.

Shame. It's a case, then, of either another repair (but I would bring the failed one to their attention just in case they reduce the new repair price), another lens, or conversion to screw-drive only.

As I said in my post, it is possible to convert the 50-135. link

It depends, I suppose, on whether the relative silence of the SDM focussing is worth spending more money on?
