WAHOO 203FE back from overseas With CFV ability now
- Thread starter fotografz
- Start date
I have the same question. How can Austin be be so definitive and absolute without having a back to inspect or know what the company has up it's sleeve?
For ex&le, here's a mystery ...
The CFV has two sets of four gold Data-Bus contact points. One located in exactly the same place as found on the E-backs.
The other set of four points are located on the opposite side but higher up.
There are no corresponding electronic communication points on a 500 series camera for any of these data-bus contacts.
There are no corresponding electronic communication points on the camera left side of the 203FE where the mystery data-bus is located.
Why would Hasselblad put gold data-bus contacts there if none of the existing V cameras can use them?
What am I missing here?
Those are the physical facts, the purpose for which we can only speculate.
Are there electronic paths in this back as of yet unused?
Could it be a hint of a possible future V camera, and this CFV was "future engineered" to work with it?
Is it a clue of a larger sensor in the same housing for an updated V camera? Perhaps an AF
able camera like the Rollie that uses the new Schneider AF optics?
If none of the above, then why are they there?
Inquiring minds want to know.

The upgrade is not free. It cost real $.
For 450$ they could even add a gold data bus on the other side à la "ELD" way.
BTW with CFE lens the exif-data of lens value and speed are transimited to the CFV's generated files ?

So that is what the second set of data-bus contacts are for? The ELD? If so, mystery solved.
I can't recall how the ELD was set up. Anyone with an ELD that can confirm this? There would be data contacts on the left side with the film back off and the camera exposed.
Of course the "upgrade" cost something Isidor. Why would they do it for free?

Marc,
> Why would they do it for free?
To sell CFV back !
When I baught a 500cxi body I recieved a card to order a free convertion set for tripod.
30 years ago I sent part of gear of my 1600F in Sweden to explain what part is broken. They sent back the complete gear setted lubrificated for free with documentation and certification of the year my body was built.
It's called a "geste commercial" in french.
Of course it helped me to keep Hasselblad in mind later when I had to buy new hardware.

Hi Marc,

Because I do this stuff for a living and have over 30 years experience in designing digital imaging equipment.
BTW, I didn’t say anything about the back, the back was designed subsequent to the body, obviously, and would have to have been designed to accommodate the design of the body...namely the I2C triggering, plus the ISO reply.

One guess (and this is purely a guess) is they could be for diagnostics.
Does this back use an adapter to mount to the V body, or is it %100 a V series only back?

Austin

That's the copy of the responce recieved in january from Hasselblad inport in Switzerland:
Q: Can I use the CFV with my Hasselblad 200- series camera?
A: A solution allowing the use of certain V-system cameras from the 200 series with the new CFV digital backs without the use of external cables or connections has been devised.
A permanent modification to the camera itself is required, however. The modification includes an exchange of the main electronic circuitry in order to provide a synchronization signal via the interface contacts. The exterior rubber pad is also replaced as an indication that the camera body has been modified in this manner.
Please note that there are several points to highlight in this regard:
The modification can only be done on the following models: 202, 203 and 205 and no other.
In general, it is NOT to recommend using the f-sync from a 200-camera to trigger exposure at all, since the timing requirement is very loose... AND
There will be no f-sync at all for exposure times shorter the 1/90. With
The modification of the 200-camera, the combination will be VERY nice though. No cords - just expose. Set the exposure time on the camera and the back will follow. The backside is that you will loose the automatic transfer of ISO to the film magazine. But, who needs film...
The modification has to be carried out at Hasselblad in Göteborg, Sweden. No other Hasselblad Authorized Service Center will currently be able to offer this specific modification.
The cost of the modification is set at SFR 425.-, excluding freight
10 working days are required as minimum turn around time for the modification.
