Sound plausible, the press conference is at 10.00am in London tomorrow, probably breaking earlier than that elsewhere in the world. Live preview (howls of protest) Only 10 megapixels (triumph of sanity) 6.5 fps (nice) Silent shooting mode (electronic shutter with mirror/shutter open - valuable) Tethered USB HD possible GPS data embeddding possible Wireless g possible Gigabit ethernet tethered operation possible HTTP embedded interface option for tethered operation Auto ISO defaults to 400 and spans 100-800 - means they must be confident about 400 quality 14-bit conversion and a highlight extended mode But basic ISO just 100 to 1600, 3200 is a menu accessed option 1/250th flash Interchangeable screens including one you can really focus on Totally new CMOS AF module with very high precision crossed unit for f5.6 or darker lenses (ie typical superzooms at the long end) David -- Icon Publications Ltd, Maxwell Place, Maxwell Lane, Kelso TD5 7BB Company Registered in England No 2122711.

You're right that the live preview feature will draw howls of protest, but only until the protesters find out just how useful it is, when they will demand the same from "their own" DSLR manufacturer. Of course some manufacturers, notably Olympus, already offer this very valuable feature. The silent shooting mode, auto ISO, 1/250 sec. flash synch, choice of focusing screens and low light AF module signal serious intent, as these are also among the key features of the "pro level" Canon DSLRs that will be announced soon. |

Electronic shuttering is very interesting. What are the speeds available for this? What is the max sync speed available with this? (If the max sync is 1/250 and they don't take advantage of electronic shuttering to push this to 1/500 or higher (a la D70 and others) it is a waste of potential. GPS data embedding. Good! Gigabit ethernet! This could become (s/w prob required) a very high res movie camera when combined with live pre-v. Interchangeable screens is great. Good spec. It seems like Canon are really testing the want for certain features with this model. Thanks for posting the highlights.

I've found that most DSLRs need around -.7/-1 exposure compensation to get something vaguely acceptible in the highlights anyway. This means that at an ISO the manufacturer calls 100, the shutter/aperture combination would indicate you are really using ISO 160/200.

This means that at an ISO the manufacturer calls 100, the shutter/aperture combination would indicate you are really using ISO 160/200. This is pretty much a copy of Minolta's 'Hi' or 'Hi200' mode from the 7D over three years ago - if you set this instead of a regular ISO setting, the camera exposed as if set to 200, but the sensitivity was really just left at ISO 100. A different JPEG conversion was used in-camera, preserving highlights. If you shot a raw file, you could see straight off how it worked - the raw file was dark. The same mode has continued to be offered in the KM 5D and the Sony A100. The difference with the Canon mode is that it works across a range of ISO speeds - I guess KM/Sony did not do this, because of noise issues when you underexpose a higher ISO image, then brighten it in raw conversion. Canon must have some confidence in the noise levels of the 40D, compared to the 400D. David |

Canon must have some confidence in the noise levels of the 40D, compared to the 400D. The 400D is already exposing 1/2 stop lower than other Canon DSLRs (it meters for about 85% of the stated ISO, as opposed to the 120% used for the other Canons), and if you set a contrast level of -2, it will automatically roll extra highlights into the JPEGs (moreso than the other cameras do at - 2 contrast). -- John P Sheehy |

Both cameras meter for about 120% of the stated ISO. I meant to say that based on a standard of 3.5 stops of highlight headroom above middle grey, the real sensitivity of the 400D is about 85% of the stated ISO (compared to 120% for other Canons). -- John P Sheehy |

Canon should be totally ashamed of this (and some others too) HP got this basic and absolutely essential thing right in their little digicam that's cheap even for a P&S, so why can't Canon?!!
