CFV BACK SECOND TRY

Austin:

I'm not sure 1/800 is that significant an "advantage" over 1/500>

I agree, I just mentioned it with respect to digital systems. I am not sure what other digital systems match 1/800 flash sync.

I did use 1/750 to correct the exposure and felt that it was a quick fix.

Please note I only spent a short period of time actually using the camera, but I know it is one of those cameras that will accomplish the task at hand very well.

Bottom line if I wanted a digital camera system I would buy one. But as I told the rep, I wanted to buy a V system and now I feel that someday I won't have a choice to buy what I want, and I don't like that. The watercolorest and oil painters have a choice. I don't think it is better than the V system, certainly not for what I do. I do understand the business aspects for it. When film dies my system will rest along side, the mimeograph, typewriter, ice box, reel to reel, phonograph, and other modern inventions .

It is the apples and oranges argument. What the pros need and what we want are two very different things and the market is going there way. I wish it was like the Swiss watch making establishment that did not follow the plastic watch syndrome. The fine art of making film cameras that will last generations is over.......................

Film will not die . Not for quite some time , or you could also say , not as long as the H3D system lives .
HASSELBLAD has launched the H3D-31 . If you read all text carefully , you will see , there is also a film back , which can be attached . I don't know , if HASSELBLAD delivers the film back with the camera , as a backup , if the back should fail or if the film back is optional .
But it could very well be thought as a backup , because tilt sensor could turn up and make your shooting implausible .

Just returned from my assignment. Bitter cold location shoot. Part of a year long job to build a library of images for a major Cemetery in my area. Winter shots now, then Spring when their flowers come up, then Summer sun rise, Fall colors, plus some interior/exterior architecual work of spectacular Deco buildings. My icy fingers still hurt.

You gotta love this work. A wedding one day, a Cemetery the next.

Did shots with the H3D/39 to the Imagebank. Very harsh lighting. Used a Metz 70ZM-5 on ocassion for fill. Pushed the 1/800th sync. to the max even at ISO 50 in order to open the aperture for the controlled DOF that my art director wanted (Sorry Austin, 1/500th wouldn't have quite got me there, but I could have used a ND filter if it was a 503CW.). Did use Lee ND grads to hold the sky from burning out. Shots done with the 100/2.2, 50/3.5 and 300/4.5.

Downloaded everything. Excellent performance from the gear.
 
Hi Marc,

As a note, a leaf shutter has different shutter speeds depending on where in the radius the shutter is at what time...so you'll get a range of shutter speeds in the same image. I assume the lenses you are using are leaf shutters? So, once again, I question the acutal necessity (or accuracy) of a 1/800 shutter over that of 1/500, though I don't dispute your metering would claim that there was some difference. You only have a 1/2 stop of latitude? And, the back only goes down to ISO 50? Gee ;-)

BTW, if this 1/800 is an issue for you, you could always use a Rollei PQS lense, which is good for 1/1000 ;-)

Austin

Since the shutter opens from the center, and at some point is open as far as the diaphragm, the time it takes to open 'fully', the time it remains open 'fully", and the time it takes to close again also depends on how far the diaphragm is open.
At smaller openings it is fully open sooner, takes shorter to close again, and the effective "fully open" time is longer than at larger openings.

But that of course does not mean you get different shutter speeds "in the same image".
The entire image is exposed as soon as the smallest opening has occured, and the entire image is exposed until the shutter is closed again.
So even though the effective shutterspeed may not be the one you had expected, you do only get one shutterspeed for all of the image.
 
Interesting. And I agree, it's probably splitting hairs. But I assume this principle would apply to the 1/500th sync also.

In the end I'll take anything I can get. And yes I know the PQS lenses deliver 1/1000th. Nice.

Really, in practice for most strobe work the flash duration determines the "real shutter speed" so to speak. It's in ambient light using fill that the higher shutter speed can help a little.

It was so freakin' cold that I should have increased the shutter speed on a few shots to over come the vibration from my teeth chattering : -)
 
Hi Q.G.,

Oops...I accidentally clipped the wrong parts of two sentences to make one! Thanks for pointing that out. It should have said you get a range of shutter speeds -depending on the aperture-, not -in the same image-.

At higher speeds, and wider apertures, that may be quite significant.

I rarely post here but I am hopeful of a larger square back even if it's only 47 square. I have accumulated a lot of V equipment and want to use it. I shoot studio fashion and the square is a great solution. I am tempted to get the CFV but feel a 1.5 crop factor is just too much, 1.3 maybe I could live with. Is it just a dream? I can't afford a P-45 or any such nonsense.

I also have a lot of Leica gear(m2, M6), including an R-8 but I bought a 2nd hand 1DS and a handful of lenses last year as my digital solution at half the price of a DMR, film was impeding my work. I am with Marc though, Canon has no soul and I want to see an R-10 and I would gladly go back to my manual focus Summicrons!! I am not a pro but I do shoot 1000 frames a week...that's what you do in fashion, it's 10-1 for sure.

The specs for the H3D-39 say , it will work from 0-45C . When you say it was bitter cold , how could the 39MP back then work ? ? Does HASSELBLAD supply a device to keep the digital backs at working temperature , or did you "hide" your gear under your coat . This was once a recommendation from HASSELBLAD , but that was at the good old time of analog photography .

My CFV back does not work at temperatures below 15C , but this might be due to the "nude studio feature" (optional) of my back . Sorry for beeing sarcastic .

Jürgen
 
-45C is about -50F isn't it? Where do you think I was shooting Jurgen that it was -50F ?

4 hours out in 12F is pretty cold for this city boy. With the wind it probably was more like 0 degrees. The only concern I had was the battery for the Imagebank. So I did put that inside my coat, and ran the connecting firewire down my sleeve. The camera seemed to like going for a winter frolic.
 
Sorry Mark

There is a misunderstanding of the figures .
The temperature specifications for all HASSELBLAD digital backs are the same and as follows :
Lowest point is 0 celsius and highest point is +45 celsius . (0-45 C) --> better ( 0 to +45 C )
In Fahrenheit:
Lowest point is +32 Fahrenheit and highest point is +113 Fahrenheit ( +32F to +113F ) .
That looks better .
The specifications for other brands , like LEAF and PHASE ONE will probably be the same or at least very similar .
 
Additional : +12F is below the specifications . So you are lucky , that your back worked .
Or should we say , that HASSELBLAD garantees a working back when operated within the specs. But it could well be , that it still works , even when the temperature is a "bit" below or above the limits ?
 
Hi Jurgen,

The "operating conditions" is the range for which the manufacturer guarantees that the product works correctly. That does not imply it will immediately stop working outside this range. You might for ex&le(!) loose a decent display on the back's LCD screen in extreme cold, with the capture of the back still working fine. And, like Marc already mentioned, it might be the battery giving up first in the cold.

Basically the silicon chips have their specific operating ranges. You have the "normal" or consumer temperature range, for automative use the range is much wider (extremer temperatures in cars), for military use (MILspec) the range is rather extreme. Price go from cheap, to reasonable, to extreme (MILspec).

hth, Wilko
 
I guess my hot little hands saved the day! I did take the camera into the warm car when my hands gave up. So that probably helped.
 
Wilko

No service menue and no diagnostics to be run on the CFV BACK . Just a "stupid" device where the customer can't do anything at all , but send it to HASSELBLAD , if it fails .
They obviously can't service the CFV BACK as well . So . . . . . . .
Nothing new at the CFV front , but waiting for a qualified answer from Christian Poulsen .
Tilt Sensor is watching you .

Jurgen,

Sorry to be unclear: normally service menus are not documented in end-user documentation. And typically you can only access them by using a 'magical' combination of keys or something like that. So selecting by accident is made quite difficult on purpose.

Note that I am not saying the CFV has such a service mode. I was just wondering.

Wilko
 
Yes Wilko , you are right

Might be , or better , shurely , there is a dignostic possibilty . The service people must be able to run "diags" , or read out an error log , to see where
z04_auslachen.gif
hides . But the key combinations will never be made public . What for ? ? ? No need . Even , if i would know them , i could not do anything . Hopefully they can . Hahahaha
 
Dear William, it is noted with interest the enthusiasm for the CFV, it has to be asked why it has to take a photographer to sing its praises when Hasselblad UK did little to promote this back. It took over a year to be sent ex&les of prints and even those were sent on a CD which could not be opened, taken through the back of a Mamiya RZ instead of a Hasselblad. May be you could influence the UK to now send out advertising material to promote and encourage users to purchase this back. It is most disappointing not to get sensible information or ex&les of the backs capability. There appeared to be a problem with ex&les being sent to photographers, they did not have any.

It may be too late for us to purchase such a back as no doubt new ones are in the pipeline so we may as well wait for those. please contact direct if it is felt that this back is worth a purchase, Hasselblad Uk certainly have not convinced us. best wishes, Carl
