I thought the previous hassy 39 sensors were 36 x 48mm- so larger than the current h4d40 at 33 x 44. Maybe you mean the 39 is he same sensor size as the 50?http://www.flickr.com/photos/brianhirschfeldphotography/
I have sections for the H3Dii-39ms and H4D-50. The 39 is similar to the H4D-40 in terms of resolution and sensor size. I definitely noticed a difference between the two.

Sorry, but they are NOT similar in size.http://www.flickr.com/photos/brianhirschfeldphotography/

Marc,The two cameras are somewhat different, so how and what you shoot could be a determining factor as to whether it is worth the extra tariff.
The 50 is a 1.1X crop and the 40 is a 1.3X crop factor. So focal lengths are effected ... however, the HCD28mm is D lens, meaning its 28mm taking area is fit to the sensor size of the 50 ... and when used on the 40 produces a 1.2X factor making it about a 33.6mm focal length. Same 1.2X factor for the HCD35-90 zoom. Used with the larger sensor H4D/60, the 28 has a sliver cropped all around, so it is 28mm but the resolution is then about 56 meg. The HCD 28 has a image circle that will cover the full 60 sensor, but it is not recommended for critical use, and the true taking area can be had in Phocus by selecting the auto crop for the H4D/60 application.
The 40 does ISO 100 to 1,600 and is the newer sensor design. so ISO 1,600 is better than ISO 1,600 from the 31 meg cameras ... the 50 does ISO 50 to 800. The 50 is better in the studio, and brighter ambient, where the 40 is better for hand-held and does a very good ISO 800 and 1,600 if exposed and WB correctly.
The 40 uses micro lenses and the 50 doesn't. So if you use a tech field camera with view lenses, the 50 is the better, easier choice to use for this application. the HT/S1.5 is part of the Hasselblad integrated system and corrects for the H4D/40's micro-lens color cast.
As usual, application and preferences drive the selections.
(BTW, the 50 can be upgraded to a H4D/50 Multishot 50 or 200meg if you do still life work. It can still be shot as a single shot 50.)
Hope this helps a little,
-Marc
