Lovely images and well composed, but do yourself a favour and buy a monopod for birding. Many of these shots are not quite as tack sharp as they might be if the camera was not handheld.

This is taken from the literature that is available so far. I suspect that the K-7 and other SR equipped bodies will need a firmware update for this to work on any of those bodies and historically, Pentax has not released firmware updates of their obsolete cameras.

Matt's guide is more relevant to the flashes and their features than the bodies, so yes, it's equally relevant to all Pentax DSLR bodies, including the K5 and probably the 645D as well.

You're welcome.

If you buy or build a computer with the right components to do a job efficiently, with the right maintenance (defragging, registry cleaning, etc) it will continue to do that job for as long as you use it, just as efficiently as the day you bought/built it. Hardware/software failures excepted of course.

The problem is, we continually load our PC's with extra jobs, extra software, updated software, trial software, etc. It is this increasing workload that causes a PC to eventually become unsuitable for the tasks we now ask of it.

So buy what's right for your needs now, but with extra power & expansion capabilities for the near future.

Pentax have 3 true macro lenses in their current lineup, at 35, 50, and 100mm. All are AF/MF, but I wouldn't be put off buying an older MF only lens. To any of those you could add extension tubes or a bellows to get greater than 1:1 magnification.

You'll get varying opinions about which lens to use for which subject. Here's mine. The 35mm is good for static subjects. The 50 is good for static and live, but sedate subjects. The 100mm is the one to go for for taking pictures of bugs in general.

There is a SMC Pentax-FA 200mm macro lens in the wild. If you can find one, it'll set you back somewhere between £1500 & £2000. The Sigma 180mm EX DG 1:3.5 macro lens is about the nearest you'll get to the FA 200mm. It's my favourite lens.

Birds are not usually considered to be a subject for macro-photography because to get 1:1 magnification, you need to be too close.

My question would have to be, as my mobile phone has GPS, why can't it be built into new bodies?. I think it probably will eventually.

I've been in the IT/computer business since the early 80's and the best advice I can give, and always have, is, buy the best you can afford. If your budget limits you to an i3, then buy it. Otherwise buy an i5 or i7.

Even if there isn't much difference now, when newer versions of software are available, they are almost always more resource hungry than previous versions.

You wouldn't need the paper Dave. If the GPS can store track data, software is available to match the date and time between images and GPS tracks, then tag the image with the GPS data relating to that data and time.

I use a very old Garmin eTrex Vista, and it works fine, but it won't track stars .

Simples.

This is only required when using lenses that have no 'A' setting on the aperture ring.

If the lens used has the 'A' setting and you prefer setting the aperture on the camera body, there is no need to enable this custom setting.

If you use the lens's aperture ring to set the aperture, and this custom setting is not enabled, the shutter will not fire.
