Bob from Plymouth: I'm not sure why people are suggesting that to include RAW would neccessarily increase the price. It's just some additional software which is probably already written for the processors of their other cameras. It must be a marketing decision but I don't know why?
As well as DSLR kit I have a P300 and it's a great pocket camera which can produce some surprisingly good results. Forget about the sensor size and all the other points being debated, it's a small camera with a bright, wide-angle lens, just take it out and use it. I'm sure the P310 will do very well.
P510 certainly is a bridge camera and not a DSLR. Brdige camera (DSLR like) use small sensor to catchup superzoom, if the sensor is bigger, so the magnification should be reduced, except they make longer zoom barrel and even should make bigger diameter zoom barrel, if necessary. So, all kind of camera has a trade-off. RAW maybe necessary or not depends on the users. I agree that RAW existing maybe a trade policy. Fujifilm have many product line in their bridge camera, all of them based on one camera only, but the magnification is different and we can choose including RAW or not and also use hotshoe or not (8 type of cameras). Please see Wikipedia: Bridge camera.
raywes: Nothing has come along in a while to compete with the Sony HX100v, but this changes everything. Along with the Panasonic FZ150, these two cameras will bed the new leaders I predict. And I thought I had my mind made up about purchasing the FZ150 already.
Certainly has hidden ''hot shoe'', please open the cover behind the pop-up flash. Canon SX40 HS and also the previous have Ultrasonic Motor and it cannot be beaten by almost superzoom camera. Canon flash compatible are also avalaible, such Young Nuo. It should be considered, if we want to buy a camera. No camera will fulfill alll needs with low or reasonable price. Please consider also Fujifilm SL 300 which has also hot shoe, but the compatible flash (same as Nikon) may be difficult to find.
NoNerd: l have a SX20 and after 3 years it feels like it is getting worn out so l was waiting to buy the SX40 as a replacement, which l will not as just like the SX30 it runs on a IONLithium battery and not AA's. For me a bridge is a travel camera. This year l have spent 2 weeks in the Sahara and 2 x 2 weeks in the Himilayas in both cases there were no possiblities to charge batteries, which didnt bother me as with the XS20 l use lithium AA's that allow abt 1500 shots. l have now bought a Fuji HS20 (uses AA's!), but l don't like it's handling. Could Canon PLEASE make the XS50 for AA's. One last remark for those who want RAW on a bridge. My HS20 has it and uses abt 15 seconds to calulate a RAW shot, so no travel camera. It can only do this because of the manual zoom elec.consumption is low, but for a traveller it's a useless camera as you can't make fast situation shots of people and movements.
There are Chinese charger for Li-on Battery (for all mobile phones) which is generated by one AAA battery and if the AAA battery run out, just replace the AAA battery. It was very useful when the light off and we need to charge our Li-on Battery. The price is about $2 to $3 each. Hope it will solve your problem.
