Ha! They'll probably end up on some review website as examples of Pentax tracking autofocus!!

Some effective pan and zoom effects which catch a racy character and flavor of the event.

Also let's remember that over time the grain in films was reduced as things progressed, particularly with colour negative. I remember using ISO 800 Kodak Portra that was very smooth, nothing at all like the usual associations with 'high speed film' that were common at the time.

So even film types had the variations that we now think of that exist between different camera sensors.

The big liberation that our latest DSLR models give us is to reduce the worry about high ISO if it's needed ..... We have a far higher range of options for correct exposure control when speed or aperture are more important. Did many people use the TAv or Sv modes on their film SLRs ...?

There are some punchy reds and more subtle blues that give the images a distinctive tone.

It was interesting to see the exposure data ... I suspect these were shot using TAv ? Looks like the days of you worrying about high ISO and noise are long gone Alan.....

No, I'm no master of P-TTL cables at all, I've never used them! I've tried to pick up the ins nd outs of them from forum discussions in order to offer up some basic guidance in my Guide. From what I've read and been informed of, if you have the hotshoe adaptors that go with the cord then any Pentax P-TTL model will work with them. I think it is the older '540' model that has a dedicated socket so you can avoid one adaptor .....

Just checked my AF-540FGZ and there is a plug socket with 5 small holes ....

Lennybloke, it was a thread of yours a few months back that had a lot of discussion on this and was very helpful .... Could you link to it here perhaps?

I hope you get these sold unlocker, from the pics everything looks to be in lovely condition.

Super sharp action captures! Very good job there ..... Now you'll have to share you're secrets .... You must have a special set of focus point array selections and AF-C mode choices up your sleeve .....

I think the idea of a layer blend of the two would be very interesting!

A very interesting comparison! It certainly throws into stark relief the effects of the different lighting involved. The contrast difference is quite extreme. I am sure that many will probably prefer the first, for its 'softness' and gentle tones ... I personally feel it needs a bit more bite to the contrast (which might be easily dealt with by processing).

The second has all the bite, and sharpness, that comes with the extreme contrast, although the black background is not so supportive really. On balance, I prefer the look of the flowers in the 2nd, and the quality of light thrown onto them.

That's right, his recent move back to Pentax has caused an unexpected upturn in the Consumer Prices Index
