Sheldon Square where the W2 store is apparently located is an office complex with real shops. It is also across the road from Paddington station if anyone wants to visit a bricks and mortar shop.

There you go: 1 Sheldon Square is a Novotel Hotel!

One thing to bear in mind is sample variation. I have had three copies of the Pancolar, only one of which I would say is a match for a 50/1.7. I am amazed at he prices these lenses go for.

For cheap(er) glass around 50mm I prefer the various incarnations of the Helios 44. It is slightly longer (58mm) and makes a better portrait lens on digital.

Another very good lens is the Yashinon 50/1.4.

Hefty - you cannot normally use an M42 lens on a Nikon due to registration distance issues.

I hope they turn out well. Lack of stabilisation is not a problem is the shutter speed is high enough, at least 1/60sec for a 50mm lens. With an f1.4 this also helps, but shallow depth of field might then become a problem.

If any one wants a thread adaptor I have 3 spare (don't ask why), free to a good home.

I have a Manfrotto ball head - excellent for smaller setups. Can't remember the model number.

This doesn't deal with the poor service from Pentax but at least you may have a usable lens.

Try Harrow Technical. They should be able to deal with this.

Perhaps Pentax will move back to Sony sensors for a K7 upgrade?

strangely, Sony's full frame cameras get a bad press for sensor noise.

Mike P: those look prety good for a budget camera.

I think the latter two are possibly underexposed. the first one looks ok.

Thanks to Rob - the filter case arrived today and is perfect.
