Thanks for the suggestions folks but I've not lost any images.

Yes you're correct Matt, I get "card error" in the cameras and Windows asks me to insert the card into the card reader - so it effectively can't see it.

I'm not sure where the 256 card is at the moment but I can send you the 128, to see if you can do anything with it.

BTW, the Trust can also use MMCs and as they are particularly cheap, I think I may try one of those.

Thankyou for the links, Matt, I'll have a proper read through them later when I've got more time.
All I get on the cameras is "card error" and I can't format on the pc because Windows can't 'see' either card - "please insert card into the removeable drive" - or words to that effect!

I think I might contact Trust, there's a two year warranty on the camera and I think there's about a month left but in any event, they might be aware of the issue and be able to advise - not too hopeful though!

The camera itself is pretty good - Samsung lens, Sony sensor and the 5MP interpolated resolution is remarkably good and I've been very pleased with it's performance, for a cheapie...........but it's no good if it 'eats' SD cards!

Thanks for your help so far

I have three cards - a 128MB, 256MB and a 512MB, all Viking (Toshiba).
Has anyone else had problems with these or any other brand for that matter?

The 256 began to display decode errors when playing back images on my Trust 910Z compact but the images were still visible on the pc. I downloaded the files and reformatted (in camera) and then the card was no longer recognised - "card error"
The 512 has been used exclusively in my DL and so far, I've had no problem with it but I wanted to use the 128 in the Trust this coming weekend.
After viewing the stored images (128 card in Trust), I opted for the 'delete all' option, rather than formatting but once again, "card error".

Now, neither card will work in the Trust, the DL or on the pc via a card reader.

Viking is a cheap make and the 512 cost about the same as I paid for the 128, 2 years ago............so are they 'cheap and nasty' or have I just been unlucky?
Do you think that the Trust camera (which I happen to think is very good) is somehow damaging the cards?

The 512 is staying put in the DL for the time being and the Trust has 15MB internal memory so it is at least usable but I don't want to buy another card, only to have it destroyed by the camera - so much for Secure Digital!

This chap's done a good here, you can see the differences between lenses and file formats and also between cameras.
I think it's a pretty comprehensive review of the equipment he had available and he's provided a significant amount of detailed information - check out the various links at the bottom of the page.

A couple of years old now but well worth a look if you haven't seen it before.

Not strictly relevant Matt, but I've got a Tamron SP flat-field 2x converter (the good one) that I picked up quite cheap because of a misty rear element.
It was a simple job to unscrew it and a gentle wipe with a lens tissue removed the mistiness completely.
I don't know what caused it in the first place but it's remained clear ever since - so you never know

In defence of Parceline - even though I work for a rival delivery company, I recently bought a laptop (from eBay), that was delivered by them.
I also received the yellow card because the driver attempted to deliver in the morning and I was sleeping (I work nights) and didn't hear the bell.
I awoke less than an hour later and phoned the number on the card, I too was not happy with the automated response and decided to do a quick search on yell.com for the number of the local depot. This put me through to a real person and he tried to contact the driver for me and had no reply but asked me to phone again about an hour later - which I did.
This time, the driver said that he would try to re-deliver but couldn't guarantee making it back to me that day, which I thought was fair enough but thankfully he delivered it by 5pm (approx 7 hours after the initial attempt).
I must say that I was very pleased with this, although it took some effort on my part ie. finding a way around the automated number, but at least the driver hadn't left a valuable item on the doorstep which so many couriers tend to do these days.

If you do get a card from a courier, it's worth remembering that most if not all drivers can be contacted en-route, - it worked for me!

Well, which one do you like the best?

Generally speaking, marque lenses ie. Pentax, Canon, Nikon etc. are better than equivalent independants but tend to be considerably more expensive.
Tokina rank as one of the 'best of the rest' and they have produced a number of superb lenses over the years, along with Sigma and Tamron and a few others.
There are sometimes compatibility issues but they normally affect the way that the lens communicates with the camera and only really affects sophisticated program models.
At the end of the day, only you can decide which one you prefer and I've no experience of Tokina but I know they are generally well regarded.
What you can be sure of however is that the Pentax lens will be very good if not excellent, built to the strictest tolerances and a perfect match for your camera body.

Do let us know which you prefer and why.

Tokina use Hoya glass - excellent, but just how 'Pentax' is this lens?
The collaboration with Tamron produced the 28-200 which is a very good lens, esp. for it's zoom range and I like Tamron very much but it's not really a Pentax lens, is it?

As far as I can tell, the DS2 is a minor step up for the DS - the most significant improvement being the larger LCD screen taken from the DL.
The DS/DS2 and DL are essentially the same, the original D is of an older specification but more manoueverable because of it's pro features, such as the battery grip.
The DS2 might be viewed as the top of the range until a pro spec replacement for the D is released but that should be a considerably more potent machine than the DS2.

ok, ok,
