Err, I would think the Canon A650 IS is the obvious choice? It's the only compact (not SLR) that I know of with the twist LCD. BTW, many of the newer LCD designs have a wider viewing angle than you may be used to. That wider angle does close the gap with the twist designs for odd situations..
I was tempted by the A650IS but, as far as I am aware, Canon has stopped manufacturing this model and distributors worldwide have only a few runouts left, meaning that Canon has something new in the pipeline. Whatever Canon comes up with in August/September might fit the bill but, meantime, I was wondering if any other manufacturer did anything that met the criteria...
Look at the Canon S5 IS, it's got the twisty LCD, 12X optical zoom and really a well regarded camera......I have used one and liked it.....although rumor has a new replacement is forthcoming....Costco has the S5 on their web-site by the way..I try not to pole vault over ant hills..
If you want to stick with Canon then the Powershot S5 IS is probably your best option. I had an S3 (previous model) which was almost identical (S5 has few more pixels and face detection AF) and it was a pretty good camera. 12x optical zoom (up to 40 something digital but who cares), full manual control (P,S,A,M) twist/flip screen etc. The only thing on your list it doesn't do is HD video..
Also check out the Fuji S100FS. It's also got a huge zoom (14.3x 28-400mm equiv.), twisty screen, manual control and video modes. On top of that it will also shoot in RAW format which is a bonus. On the down side, it's bigger than the S5, more SLR size, but it is a fixed lens camera. Have a look at http://www.dpreview.com/reviews/fujifilms100fs/ for more info..
Hope this helps.
Thanks, Chris and Steve. Most helpful..
Forgive my ignorance, but do you happen to know if widescreen (16:9) format is merely one switchable option within a P&S that otherwise shoots standard frame, or do widescreen-format P&S models shoot widescreen and widescreen only?..
It's always switchable. The interesting thing is how the LCD is handled. Most will have a 4:3 LCD, then crop top and bottom for wide screen format. But I believe there are a few cameras that do their LCD the other way..
