rbubbly, what is your mode dial set to. I've tried this myself and in green mode the option is greyed out as you describe. In other modes, it is selectable.

Anvh - I beg to differ. Rbubbly did in fact say "Extended bracket" and that is the option I'm talking about. I am shooting in RAW and i can select it but not in green mode.

Here's another of my wee feathered friend...

I'm guessing you might have the mode dial set to the "green" mode? In this mode some of the more manual features of the camera are not available to you. Switch to one of the other modes such as "P" and you should find it is selectable.

Taken today at the Royal Botanic Garden in Edinburgh during my lunchbreak. I love this little guy - his colour and markings are fantastic.
Pentax K20D, Tamron AD LD Di 70-300

I've heard that the Magic Lantern guides are a pretty good purchase. Having just got my K20D last week, would it be a worthwhile investment? (they are very cheap afterall at approx £10). What would they give me that I can't get from the manual or from support on this forum?

Great news Peter (remember to update your signature!) Not so great news Mike! I had thought about holding off to see if they bring out a new body but to be honest the K20D is more than advanced enough for my skills plus I just decided to stick to a budget that I was prepared to spend. If the new body comes out it will probably be significantly more expensive and I just couldn't justify that.

I've not had much chance to play with the K20D yet to be honest - partly because of the weather and other commitments such as work, etc. - but I love it already. Especially how customisable it is. My partner is also delighted with my gift of my K100D and we're both looking forward to days out with our cameras.

Hi Anvh. Yes, I installed the code months ago on my main pc and on the laptop but to no avail. I'm disappointed that Pentax haven't released a 64-bit version especially now that Adobe have a 64-bit Photoshop (which I use).

I've used the convertor before but I guess I'm concerned about archiving more than anything. I don't want to archive thousands of images and then find in years to come that I can't open them with anything. Maybe the answer is to make sure I backup the JPG files as that format is likely to be with us for some time to come and seems fairly standardised.

Thanks rpk20d, however that codec only works on 32-bit Vista, I have the 64-bit version. Good point about the DNG files but not sure how often that would matter to me. Thanks for your views and help though.

I know this topic has probably been done to death all over the internet, etc. but I'd really value your opinions on this.

Having moved up to a K20D from my K100D and having always shot in RAW I'm keen to continue doing this (although I now shoot in RAW+ which gives me JPEGs too). However - should I shoot in Pentax PEF or Adobe DNG RAW formats?

I run 64-bit Vista and the one slight drawback is that the Pentax RAW codec doesn't work on it. However, I have a code for DNG files that shows me thumbnails when I browse folders. Not so much of an issue if I'm shooting in RAW+ mode admittedly.

So - what are your thoughts? What are the Pros and Cons of each format and which do you use and why?

I would contact chris@srswatford (using the messaging on this site). I did that last week and he kept me up to date on progress of my order. He's had a run of orders and was waiting on stock from Pentax for me but luckily it only took a day or so to come in. He's a good guy and the service from SRS is excellent. I know how you feel - I was excited about getting my K20D too!

Good luck.
