Aha. Now we know where Lilly's comp shot was taken

It was the FAJ 75-300 I think. I found this too, your Wedgetail I think, but it was awfully underexposed against the sky, and took a fair bit of mucking about with to see any detail.

You did better than I did at that show. A worse test of reactions and AF speed I can barely imagine.

This was the best I could manage, and it's hard to imagine a more dreadful pose for the bird, or a more horrible background . It's a fab show, though, for sure.

I do like it. However, I think there are a number of distracting elements, notably the marks on the fingerboard (especially between the lowest two strings), the curve of the pick-guard where the edge is just under the high E string, and the attachment points at each end of the pickup.

I love the idea, and I think the curve of light at the left edge of the body is just sublime, but it needs just a touch more work, I think. If you had access to a guitar without the pick-guard and pickup, those elements might be easier to remove.

Or, meter in manual mode (with the green button is easiest with the K10D since it also sets the exposure and you can change it from there if you want) looking through the finder, and then it won't change when you move away.

I had a brief look through this PDF earlier too - I thought it was all just a hoax to start with, but it certainly seems not to be.

I see it as a start, rather than a snag. According to Wikipedia, the first commercially available (I use the word 'available' loosely - apparently it was $30,000) dSLR was only 1.3 MP.

I wonder what the lower limit of the size of the microlenses is, though, and whether it's small enough to eventually catch up with and pass the sort of resolutions we see now.

Thank you. I think it must be the standard one. It just says 'SMC Pentax-A Macro 1:4 100mm', and there's nothing about it that looks unusual compared with any of the A-series lenses I've come across.

Ah.

Well I must say, I've been very pleased with it. Not that I've done much particularly to test it - but most of my eBay pictures in recent times have been taken with it, as well as this:




... which is a crop of about a quarter of the width of the K10D frame.

I bought an A- one of these some months ago for under £100.

It's in perfect condition AFAICT, but it's not for sale

What's different about a Dental Macro lens?

If you type "download k100d firmware" into Google, you'll find that the first link in the search results contains precise instructions for upgrading the firmware, and includes an answer to this question.
