In some cases all you need to do is change the header to get the converter to see the file as an old friend instead of an alien life-form. It's worth a try

Good catch! How'd you get him to stay still while you fiddled with the camera?

The fisheye lens will have a specific type of distortion, lines will be curved out. Think of it as barrel distortion on steroids!

The rectilinear lenses will have minimal distortion (the 12-24 in most cases doesn't need correction at all, it's very minimal for a wide zoom).

If you want to do perspective correction, a fisheye is defenitely NOT the type of lens you want. You need a rectilineaar lens.

For my uses, the 12-24 and 16-45 make a good pair. I think of them as two ranges that I keep on the camera depending if I'm in walkabout mode or wide mode. They're both great lenses.

I suspecrt the compact point and shoots do more in-camera sharpening, as most of the users aren't going to pull their files into Photoshop. The DSLR's usually assume a user who's sufficiently involved to get into processing, thus leaving the sharpening up to Photoshop or equivalent, because you preserve more detail that way.

In fact, most of us real fanatics shoot RAW, leaving the whole in-camera processing issue behind.

Most digital images require some post processing. Pentax, in particular, will keep down the in-camera sharpening on the DSLR's (I don't know about the compacts) so you don't lose detail. You get better results if you use an image processing program, but straight out any digital camera they can be a bit soft

I use the *st D, and there's an option to set up a two second mirror lckup which I often use if I'm too lazy to use the remote release (which you can buy at most well-stocked camera stores). It's a quick an dirty solutin, but I'd order the cable if you plan to use it a lot.

I'd go with the 16-45, it's an excellent lens. The 18-55 kit lens isn't quite up to the same level.

The 12-24 is very good, minimal distortion for a super-wide. Practically none, in fact.

If I could afford the airfare from Boston to London, I'd be really tempted.
