Thanks Steve. A very plesant stop on my way to Croft, and the teleconverter was just as described. Hopefully I can keep my LBA under control for the rest of the year, but I suspect GAS will still get the better of me.

I've not had much of a chance to play with it yet, beyond the brief session of sun you somehow arranged for our meeting.

I'd ask a penny for them. Not sure how much the listing would cost if they don't sell.
Then you run the risk that's what they'll go for, if only one person wants/spots them. I'd agree with John, wait for a free listing, and I'd start them at £5 + postage at cost.

At a guess that is two polarising filters. When aligned they will only take out a small amount of light, but as the angle gets to 90 degrees it should go totally black.
That's the way all variable ND filters work. Though the front one MUST be a linear polariser, and the second will normally be a circular polariser. With wide angle lenses they can give a darkened X especially noticeable in the skies.

To expand on gwing's near complete answer

You'd have to have a really tiny aperture to get long exposures on a sunny day. For significant effect you need shutter speeds less than a second - 200 times less than you were getting. The only way to get close with aperture is to use a pinhole rather than a lens, but the image on APSC isn't sharp and most pinholes will still have too much light ~F/180 is typical.

IMHO a fairly strong ND filter (& tripod) will be needed unless you want o wait till the sun's gone down.
If you don't want to pay out for a ND filter (most strong ones are ~£100) it is possible to use welding glass (from ~£2) but you'll get a lot more colour change, and it takes a little DIY to mount it on your lens.

Call me an old cynic - but I think some/most of those owe more to photoshop than perfect timing. But some good images in there non the less.
Some are certainly photoshopped, and others are posed, but many are good. TFS

Blaze that last shot is stunning!

I'd recommend getting at least one more memory card though. They are fairly cheap & it saves a lot of hassle if you forget to clear it before a session or one fails!

Sounds wise advise to me, if the Green Man gets up it normally means severe trouble.

Definitely an image, a nice mountainside - we don't get them round here - and the mastiff in the foreground is good too

I hope you have a long series of these images to keep us amused.
