Depends on the price and the quality difference.

Waiting to see on both counts.

Don't know what the score is on the Samsung battery grip, but the fact the Pentax one has a slot designed for the IR remote would swing it for me. Keeps it safe and at hand.

As the camera has sensors front and back the IR remote works for all the situations I have needed it for so far.

Sandisk Extreme III 2GB are currently 17.99 on play.com and in stock.

Ultra II are 14.99

http://www.technikdirekt.de/ are listing the 16-50 @ 799 euros and the 50-135 @ 899

Fair enough, we can only go on what we read and there are quite clearly a few people who have reported problems there.

I still feel that is an unusual occurrence rather than a common one though.

To put the cat amongst the proverbial pigeons, the only lens I have bought which had any problems on delivery was a 31mm limited!

Mongoose, I think you need to quantify how many is 'a lot' in your comment on people who received friday afternoon models'.

I am struggling to find a negative comment on it so I think it is far from the 50/50 your wording would suggest.

There was a magazine article a few months back where they went into the sigma warehouse and picked out several copies of the same lens at random (the 105 macro I think) and ran comparison tests because of this reported issue of poor standards, the results were very good.

I have the Sigma EX 10-20 mm and I am very happy with it.

Search the http://www.ephotozine.com/forum/ and you will see I am not the only one, it is a very popular lens and the EX series are very high quality.

I could be wrong, but I think you may all have gone off on the wrong tangent.

kcmadr asked about Multi-exposure not braketing. i.e. picking a previous shot say a landscape, selecting it for a multiple exposure and then taking a picture of the moon over the top of it. Nothing to do with braketing.

To be honest multi-exposure has to be the least used feature I have ever had on a camera and even more so since digital (just combine them in photoshop and have a better chance of getting the placement right!), but I think this was the original question.

Do you have your ISO set to Auto?

It caught me out a couple of times until I switched it off and moved ISO to a control dial

I have posted a reply on epz as well, but looking at your test shot either there is a problem with your *istD or it was not in focus.

I carried out a few comparrison shots when my K10D arrived just before Christmas and the difference between shots taken on the two was no where near that pronounced.

(For the record, I carried out my tests using a FA 50mm F1.4, FA 80-320mm and the DA 16-45mm)

I would try again using Manual focus and a tripod to rule out any AF problems on the *istD.

The K10D is a stunning camera, but the *istD was not as bad as your shot seems to suggest in my experience.
