Thanks to both of you for advice. John, tried the dust removal several times as you said, took a couple of pictures of sky and then of white wall this morning, but dust spot still there. Very annoying as there were some good pictures from yesterday's shoot. Have ordered a " rocket blower ", and hope that will do the trick.

Looking for help. Was out today and took a number of photos with K30 and Sigma 17-70mm 2.8 in various settings, outdoors and inside. Have just looked at them on the laptop and a spot is appearing in the same place in most of the pictures. It is more prominent taken against a blue sky background. I have on start up dust removal on, but I am wondering if it is not the camera, but the lens ( though there is nothing on the glass that I can see ). I have had the lens for about a year and a half, so is still under warranty and the K30 is only a few months old. I am sure there is an easy answer to this and looking to the Forum to those more knowledgeable than myself. Thanks.

Been watching the forum for a while now and read some web reviews on the lenses mentioned, but looking for advice if one is ultimately superior than the other in terms of image. Or is it the case in the real world, there isn't that much of a difference? I would like to buy a lens for portrait photography(new or mint secondhand within my budget.) Any help from all of you more experienced than I would be appreciated.

If anyone took up the deal on Jan 4th for a Sandisk memory card and have doubts the deal will happen because of Jessop's Administration, then you have seven days to request a refund no questions asked. Have been in touch with Groupon and they have cancelled mine and be refunded in a few days.

Price increase for k30 now taken place: £529 Body and 18-55mm WR lens and £459 for body.

I have a Black Kr body boxed with all cables, etc for sale. Bought Apr 2011 with two year warranty. Sadly been too much in camera bag since. Circa 1560 actuations. IMO, everything in box is in near pristine condition. £225 includes RMSD. Paypal preferred but open to other payment options. Any questions please ask. Thanks.

A long time reader of the forum, and now just joined. I am in fact looking to sell my lightly used K-r with extras and in the Glasgow area. If you are interested regarding details get in touch.
