I think he is a she (s/he changed ebay username a little while back) and no, I don't think I have seen them on here. Just someone making a buck buying kit on ebay then re-selling it at 4x the cost. Relatively poor ebay rating.

My 12-24 is pretty much permanently on my camera at the moment (in the absence of my 50-135mm). I found that I used the wide end of the kit lens mostly, and now I use the "tele" end of the 12-24... Nice to have 12mm when you want it though.

Pentax are doing the 50 quid cash back on the K-m in Feb.

Not my favourite ebayer...

I assumed someone probably did but as it was over 20 years ago I last did anything requiring studio flashes I wasn't sure who. Thinking about it, it was actually 1986. I took photos for the college ball. They were much more popular than I expected and I spent every waking moment for a week printing and sepia toning 10x8 photos. I still have the negs somewhere.

Cheers, Kris.

Presumably they work on the basis that if nothing comes back they set the lens to infinity :

I wonder how this impacts on the SR? How much difference does it make to SR if you have a 450mm lens but it thinks it is a 300mm?

Probably the easiest thing to do is tweak the white balance slider when doing the conversion from DNG in ACR or whatever your RAW converter is.

I just had a look at removing a colour cast in CS3 and it seemed strangely difficult, especially as I remember Elements having a simple colour cast correction tool.

Cheers, Kris.

A beam system would be largely useless in a camera. If I take a photo of a beautiful wide view with lovely white clouds and a blue sky, what on earth would the beam reflect off? The reason surveying equipment uses a beam is that they need millimetric accuracy over long distances to a specific target. For a camera, once the lens hits infinity who cares if the object it is focusing on is 500m away or 1000m away or even 1267.452m away? AND the time taken for a Leica Total Station to take a reading, quick as it is, would have most photographers grumbling that they had missed the shot of the goal/bird/moving car etc.

The camera can, however, make use of a beam already although in a limited way. On the AF360FGZ flash (is that the right mix of letters?), one mode is to use the flash gun for low light focusing using an infrared beam. I guess the range is limited (I have never tested that out). I also assume its big brother will do the same, and probably some of the third party flashes.

If anyone is interested in how laser technology is moving things on, google LiDAR. This is airbourne laser scanning which is replacing more traditional land based survey. One of LiDARs great advantages is that it can survey through the tree canopy of woodland. Its disadvantage is that you have to process out of the survey the readings from the person walking the dog across the field...

Best wishes, Kris.

I tried out the Tammy replacement today. Discovered I cannot hand hold a long lens while wearing a rucksack...
