This argument is still valid and active cooling (fan) does help in removing heat from the electronics. However there are other technological advances in the Credo (it is after all a much newer design!) that provide this facility and that allow us to do away with the fan and the ventsLeaf Capture was designed around the .mos format and as such it does not support any other format. Since we already have Capture One with full support for both of these format, there is little sense in putting R&D resources into adding new file support in LC I haven't dropped a Credo yet (I've done this several times with an Aptus) so I don't have 1st hand experience. I expect the replacement cost to be in-line with the Aptus/ P+/ IQ backsThe new electronics design allows us to maximise the dynamic range of the sensor with improved calibration at a very low iso setting. This also allows us to extend the maximum exposure time (2 minutes on the Credo 80)We've done quite a bit of work in Capture One to make sure that the character and the Aptus's "look" are maintained. The Credo at 35iso will give you another 1/2 a stop of DR (of course this also depends on the scene/ conditions) and obviously it can do longer exposures.
There is no list price for going from Aptus-II 12 to Credo 80 (or from II 8 to 40, II 10 to 60) since the change is not cost effective to you/ us/ dealer. The dealer can provide a price though, on a case-by-case base. Not yet...
Hope this answers all your questions?
A few other questions about the differences or similarities between the Aptus II and the Credo:
1) Does the histogram in the Credo read from the raw files or the preview file? Does it work the same way as the Aptus II
in that is it possible to take spot readings from the photograph and have it show up in the histogram. Is this info tool capability available in the histogram when shooting untethered in the Credo?
2) Does the Credo support the grid tool as it exists in the Aptus II when shooting untethered?
Are you able to move grid lines on the LCD to match the content in the photograph?
If so, how do you accomplish this without the use of a stylus?
3) In reference to the LCD panel.......are both the image area and the extended area on the perimeter of the image touch sensitive? Or is it just the perimeter area outside of the image area that is the touch sensitive screen?
4) Is custom white balance possible when shooting untethered?
5) Can you still load LCC correction files via CF card to the back for untethered use?
6) The Aptus II lasted 1-2 hours shooting untethered on the factory supplied batteries, do you have an estimate
of how long the battery lasts when shooting untethered continuously on the Credo?
I am just trying to get my head around the evolution of the Credo...are all the new features listed in the tech sheets in addition to the Aptus II features (untethered) or have some features that made the Aptus II unique been deleted?
