I've just checked mine and it's the same. Infinity focus at 18mm is roughly at 7m on the focus ring and doesn't change up to infinity.

To be honest it's not something I've ever considered. I assumed it was normal to refocus when the focal length is changed.

I love my 18-250mm. It's a brilliant travel lens and don't let the odd negative comment about IQ put you off. They are largely from people who have never used one and don't believe a zoom with this range can be this good.

It would be great news if it were true, but the simple fact is that it isn't. I was in my local Jessops yesterday and there were no DSLRs and just a solitary 17-70mm which is ex-display and shop soiled (though no budging on price) and has been there for months. This is a city store, not some tiny branch.

On line there is nowhere near the full range of lenses and hasn't been for some time. I have quite a lot of Tesco Clubcard Jessops vouchers, but nothing to spend them on! I have enough for the WR 100mm macro if only it was available. The manager in my local store confirmed that they couldn't order it in if it's not on their product list.

I don't think it's at all negative to point out that someone who purports to be from Pentax UK isn't telling the truth, for whatever reason.

Any ideas on how to do this with a K-r? I can't use a manual cable release as it's not compatible and the IR remote won't do it either. Short of a clamp holding the shutter button down I'm stuck at present.

Thanks John. I saw that, but 50mm is a bit close. Now I have the 100mm I prefer the working distance.

Good price though as long as it stays at £25

Actually Jacqui I don't think it's anything to worry about. I suspect all that has happened is that he has withdrawn the original money from his Paypal account and now Paypal need to get it from his bank before they refund you.

Why it has to take 5-7 days is beyond me, but that is a usual Paypal timescale. I've both refunded and had refunds via Paypal when there is no money in the Paypal account and the timescale and message sound correct. It's a pain, but I don't think there will be anything he can do to speed it up.

If he refunded via Paypal he will automatically get the fees back so you should be refunded the lot. Are you sure you aren't getting £193 from him and £7 from Paypal?

Not sure dropping it would be adviseable in this instance as it's the 'plastic fantastic' Vivitar 100mm!

Adding a 12mm manual tube works, but I suspect I might have been better off with an older, manual lens rather than trying to make a modern AF lens manual.

I certainly could do with a DFA 100mm 2.8, but my bank account would disagree

That's hardly the full range of Pentax lenses though, is it.

The same 12 lenses Jessops have had for ages including three Q ones - no macro, no 35mm, no 50mm etc

I'm sure that's right, but, in macro work where most people wouldn't use AF, catch in focus is a very good way of getting a decent shot, especially if hand holding on your knees in a dark corner

So much so that I've been trying to make an AF lens manual so I can use it!

Yes, absolutely. I use it frequently with the K-r, but it depends on the lens you are wanting to use it with. Let us know and I can can give you the K-r settings.

I got a bit confused by last night's post too. I would have replied, but wasn't sure what the problem now was as it seemed to be working correctly.

If you set the body to AF, CIF to 'on', take everything in the viewfinder out of focus then press the button it shouldn't fire. Keep the button pressed and bring the subject into focus and it should.

If it doesn't, can you tell us what does happen?
