The site looks like it relates to paintings rather than photographs in which case you would have to provide the painting as it would be a one off.
I do accept photographs can be included too but they're an adjunct to what would normally be sold through the site, one off pieces of art.

The 16-85 would be a great replacement covering your preferred range plus a bit more at the long end.

Just yesterday I received in the post a Pentax SMC 28mm f/3.5 shift lens which should prove ideal for architecture photography. Possibly its not normally wide enough for APS-C though.
Having said that, are you aware of the shift feature of the sensor when using liveview which can be used with any lens? It doesn't give the scope of a dedicated shift lens but does provide a useful amount of shift when straightening out tall buildings.
The shift lens came with its original receipt dated 1982 and I paid more or less what it originally cost back then. A web based inflation calculator shows that its value new now would be around £950. Makes you think.

Is it possible to hide the for sale threads in the recent activity list by means of ticking a box or unticking a box somewhere? (A bit like how the competition threads are kept separate.) Presently there are more for sale posts, bumps etc. than there are on actual photography matters.
I don't mind looking through the dozens of FS posts occasionally, but preferably only when I'm looking for something! Thank you.

Really like the contrasting silver and gold tones in 2 & 3.

But they're not seen when the thread is entered by way of Recent Activity. The original poster may see them but even then there's more than one way to start a thread without entering a specific section and seeing the other related threads etc.
As I said, in this case it helped resolve an issue that didn't start here and more good than harm has come out of the exchange. If the exchange hadn't happened the issue would still be unresolved and it did partly revolve around the camera this thread relates to. As far as I'm concerned the matter is well and truly closed.

I suspect the reason is that the camera pre-programs the four exposures which it will ensure get taken and merged. I suspect the folks at Pentax think you might give up halfway through the sequence and leave the camera in limbo and it won't know when to start the 2nd, 3rd and 4th exposures leaving the camera with the shutter open when it shouldn't be.. Its something new anyhow and in its first incarnation so if enough users are like-minded (and tell them) perhaps they'll make it a possibility in a future firmware if it isn't something likely to lead to a problem..

Hi, it seems a bit rude no one has said hello and welcome to the forum already, so... hello and welcome!
I expect people are wondering why you're worried about the serial number and the lens's construction.
Some people are reluctant to show the serial numbers of their cameras and lenses in case the numbers are used to make a fraudulent insurance claim, then when they try to sell the items they get flagged up as being stolen. It's best to be cautious.

Despite how it looked, nothing got out of hand and the matter has been resolved quite amicably. It is better to resolve misunderstandings than let them build up, or don't people normally do that nowadays?

To add to that, if the seller has to sell at a loss there is no VAT due at all.
