We're surprised when a website isn't online on time? C'mon, this is Britain, it's been several decades since anything more complicated than a full English breakfast was delivered on deadline or within budget.

Well I have never noticed any obvious effect on my photos using this method, but then I'm usually taking the shot from at least twice as far away from the subject as the external flash and not photographing highly reflective subjects.

If it's more than an opportunistic scenario where I have just gotten the flash out on the spur of the moment I will generally take the time to set up the radio triggers. To be fair Cactus v5s are quite affordable and in my experience, completely reliable. You do lose the benefits of P-TTL but assuming you want to do something as least vaguely creative, gaining full control over the power output of your flash by using it in manual mode more than makes up for this.

I believe the custom option you're referring to is using the built-in flash to trigger an external flash in control mode (option 2) as opposed to master mode (option 1). Using option 2 the built-in flash fires to trigger the external flash, but is timed to go off before the shutter curtain opens so it has no effect on your exposure. It works perfectly well on the K-5 and K-5 II. I use it often when I can't be bothered setting up the Cactus v5 radio triggers.

I can attest to that, these two are my main shooting pair right now and compliment each other really nicely.

I'm thinking about upgrading from the Tamron 17-50 to the Pentax DA* 16-50 but there's really nothing in it in terms of image quality - I only want the Pentax for the convenience of the weather sealing (and slightly faster focusing, I'm told).

Plus they're almost certainly also silver birch. The bark is very distinctive and silver birch roots have the same coloured bark as the trunk and branches (at least the part of the roots that show above the ground do, I can't honestly say I've ever dug one up to see what the roots look like under the ground. It's common for trees growing alongside water to have the upper parts of their roots revealed as the water erodes the soil away, but I don't know whether the roots already have bark or whether they only grow it as a protective measure when uncovered). In any case that distinctive bark is so bright that it isn't unusual to see burnt out highlights in photographs of it.

Apparently the Canon 1D Mk III goes down to 50 if you turn on the 'extended' ISO settings in the menu.

Yup.

These days, phones are only phones because the manufacturers choose to market them as such. They might equally well be considered cameras, pocket computers, audio players, video players, e-book readers, mobile web browsers, etc. etc. For many people using the thing to make a phone call has become a secondary function, even if they do have a SIM card. Personally, I use mine more to listen to music than anything else (ever since my wife nicked my mp3 player... grumble grumble).

So, can I enter an image taken in March 2011?



...Just joking.

+Keeping the rain off the front element of weather-sealed lenses. Or in the case of earlier tonight, the snow.
