Can you run an 'Open Day'? i'll definately come down.....

thinking in this way. if pentax brings out a full-frame camera, what a great focal lenth as a walk-about lens with f2. my issue with DA 40mm is the maximum aperture f2.8. after having owned it for 6 months, i eventaully sold it and changed to a FA 35mm. i would not hesitate to take JONES' Voigland 40mm if Pentax full-frame DSLR is on the way.

To Chris,

Has your got the prices for the newly annouced products, especailly K5?

I wish they were a SMC version

As of banding with a polariser, i do not think the polariser filer should take the all responsibiltiy. it could be resulted from the JPEG compression. the other day, i converted some RAW files to JEPG, and discovered two or tree photo with sky having the banding. i switched the default camera setting to other setting in the pentax software, like' vibrant', 'natural', 'landscape', or even 'portrait', then switched back to the camera default, suprisingly, the sky became smooth and no banding remain at all.

donot know whether you have noticed this about the newly released lens. 62mm filter size seems a little bit unusual. Lens manufacturers tend to keep the filter size consistent. e.g. traditional size for pentax lenes are 52mm, 58mm, 67mm, 77mm. apart from DA 18-250mm which is OEM'ed by Tamron, i have not come across any pentax lens in 62mm filter size. considering the origin of DA 18-250mm, DA 18-135mm is very supicious to be designed or OEM'ed by Tamron. despite tamron has not got such a product, Tamron has gained a good reputation in making tamron 24-120mm etc. and no doubt about the ability of making such a lens. Tamron may hide behind pentax to manufacture it. who knows?

Eventually, the lens has been sold to David. thanks for all interest.

The extension tube on its own seems to be sold for 30 pounds on this forum sometime ago. if somebody want the extension tube for 30 + postage, i would consider to sell it and keep this nice lens.
