. . . and here from a forum member.

I can't see why it shouldn't work and yes, the 1.7x AF T/C attaches to the camera body, then you attach the lens to the T/C. It should also give you a degree of auto focus but you'll need to manually focus to somewhere close to focus, the T/C does the rest.

I don't suppose 100PERCENTOFF would work?

I'm afraid you can George, and we often did, most often with a glass of Cava in hand.

The sunset's there are truly spectacular.

The jacuzzi can be heated to 37 degrees centigrade, even in winter. I'm told, though I never tried it myself, that the only way to avoid the cold when exiting a jacuzzi in the winter, is to be naked. I was never brave enough.

Of course George. 10% discount to forum members. Anybody here can PM me if interested.

Many apologies to the OP for contaminating your thread, but it did help you with your decision (I hope) to buy the lens.

Well, since you brought it up, it is a holiday rental villa.

It's the villa we used to live in up until 18 months ago and as we don't want to sell it, it's available at very reasonable rates.

The purpose of my post on this thread though was to illustrate what the 12-24 lens can do for interiors, which hopefully helped towards the OP's decision to buy the lens.

If interested, all details can be found here (and that is a shameless plug, if it's against the rules, I'm sure it'll be edited/deleted).

There are some fans of short macro lenses here but I much prefer the longer ones. 100mm and 180mm being my most used macro lenses.

The longer lenses allow you to maintain a bit of distance between you and your subject which means, in a lot of cases, your subject may still be there when you are ready to press the shutter release.

The SMCP-A 50mm 1:2.8 lens you mention is almost certainly a macro lens and therefore will not be cheap, but manual focus is OK. Close macro work usually requires you to use MF anyway.

You would do well to consider the Sigma & Tamron macro lenses, they are cheaper than Pentax lenses and produce outstanding results.

My recommendation would be to wait for a macro lens having a minimum focal length of 90mm for the Sigma/Tamron lenses, or 100mm for a SMCP-F/FA Pentax lens.

I think they have the letters WR on the bezel around the front element.

All of these images were shot using a K20D and the DA 12-24mm. With careful camera positioning you'll get good coverage and very little perspective distortion (converging verticals). OK, I wasn't so careful in some of them.

All interior shots used an AF540FGZ without any diffuser but aimed at the white ceiling for plenty of diffused light.

Shots through the windows would have benefited from HDR treatment but it wasn't necessary for my purpose.
