K5 Cashback is at:
http://www.pentax.co.uk/k5cashback
Some of the SRS and Pentax UK website links don't work or are incomplete.
I am tempted. Trying... to... resist...

Why not adapt the software to take one exposure, then produce the under and over exposed images electronically before combining them to produce an HDR image? This would deal with the time-lapse between exposures and result in fewer shutter actuations.
Am I missing something really obvious here? If not, I claim the idea as my own and demand a new 645 from Pentax in recompense.
New pentaxian for here (though with 35 year old Pentax kit!), please don't jump on me if I'm wrong!

If the exposure is 100% perfect at the black and white ends, the extra two images then generated would be over exposed or under exposed respectively and would not help.
If the original shot was over or under exposed, the two extra images would not recover any lost detail any better than you could in post processing.
So any extra images generated from the first exposure would not extend dynamic range (I think).


£629 cost (after cashback) and a free 8GB class 10 card, postage free, SRS ground me down. Will miss bonfire night by the time it arrives but hey...
Will sort out any new lenses later.
