Thanks John, but wouldn't the ISO just change? I have tried all sorts of combinations since but cannot get the 'hyper' message again. I started finding about hyper using the AE-L button but that just shows a star and stays a DNG file. I didn't change from DNG to PEF in the middle of the shoot so the camera must have done that at the same time.

Just going through some interiors photos I took yesterday on a K-1. All my RAW photos to date are default .dng files but for some reason the last three are .pef files. As my flash batteries had died I switched from Manual to (as I thought) TAV, but the data is showing TVhyper (?) and PEF. I cannot find any reference to TVhyper in the manual or menu, and the only RAW file reference in the menu is to a .dng file. Anyone know what is going on?

Not me, bought a Manfrotto carbon fibre pro3 tripod from Park Cameras for 215.50 reduced from 269.00 plus the Manfrotto free offer of a Pro3 head which is normally 74.26. Total saving 127.76.

Update, the discount should have been 25% so the good folks at Park Cameras have refunded 13.45, total saving 142.21. Offer on till 28th and longer for the freebies from Manfrotto depending what you buy.

There is on my mini iPad, works perfectly.

Incidentally, if using the image synch app, which is always in live view, you can touch any part of the screen and it will focus on that point no matter what the camera settings are.

Wouldn't it be nice if Ricoh made accessories like this available now, I am sure they are made as they are in a K-1 catalogue and on the Japanese Ricoh website.

Does anyone use the Pentax PF-CA35 digiscope adaptor, currently £299.00? Recommended for use with the Pentax 80 digiscope it is a lens which replaces the eyepiece. Question is what equivalent telephoto lens would that represent, and how are the results?

The worst thing in retail is when you get to Christmas Eve the shop has to be stripped and the Sales put out ready for Boxing Day so having endured weeks of Noddy Holder and ghastly kitsch when you actually get to Christmas the festive spirit has gone!

I think it has taken a while for digital cameras to reach the same quality as film but the extra variable of ISO is a real breakthrough. I am guilty of using ISO 100 whenever I can but looking back on some earlier I was amazed to find a really good photo with ISO 10,000! I confess to following my Dad's advice of buying the best you can and it will give the most pleasure. Not a great one for the iPhone mania of updating with every new model launch, I tend to keep stuff until there is a really good reason to replace it, and I do tend to get attached to things.

I liked the Joe Cornish link; set of Lee Filters hard grad + soft grad + ND filters? Hmm. I don't know about other models but on the K-1 the green button gives a meter reading in manual mode which I use 80% of the time, really useful. Incidentally there is a K-1 review in Outdoor Photography this month highlighting Interval Composite Drive mode, which combines exposures over a period of time using the same setting (not like HDR) Effectively this does a very similar job to an ND filter in smoothing out water movement, must try it sometime.
