I clicked on your link which took me to your picture in the gallery then I clicked on the picture there, and that took me to your picture on a plain background. I then right clicked on your picture and selected "properties". I then copied the url and selected "image" and pasted the url between the two sets of square brackets.


It's when two of the elements in your lens grind together and produce a fine glass powder. This results in problems with colours in your photos.

I want to take that picture.

My perfect holiday snaps - one of the Northern Lights and one of a polar bear in the wild.

That's right as far as I know. You remove it's entry from the File Allocation Table. This file holds information on which sectors are used and which are free. Basic recovery programs work by actually reading all sectors, rather than looking at the FAT. This is why if you if you accidentally delete something, you should immediately stop using that media until you can you can unleash recovery software on it. The information is still there until it is overwritten.

I am a little surprised at these answers. I have had one card in my K20 since I bought it last year. My shutter count is 3543. I formatted the card when I put it in and had not done so since.

When I connect to my PC, I usually cut the photos from the camera and paste them onto my hd. I was convinced that the capacity was 104 pictures best jpeg + raw and I still have that. To prove it to myself, I formatted the card and sure enough, 104.

Normally, I would expect deleting a file to remove it's entry from the file address table and any sectors allocated to it would then become available for writing.

Am I missing something?

Just to clarify a point, am I right in thinking that the Pentax incarnation of this lens is non HSM?

Looking at various websites I got the impression that currently it is not, but Sigma are working on it.

Seems odd that it appears on fleabay before the dealers get stock.

To replace your 18-55 on that budget I would have thought there are two choices, either DA 16-45mm F4 ED AL for which the nice people at SRS will relieve you of £269, or try to get a used DA* 16-50mm F2.8 ED AL.

So sorry to hear of your loss Martin. You will be missed.
