Hasselblad SWC or Distagon C 40 mm with CFV?

[ulrik]

Hi,
I have the problem that the CFV back does not mount to my SWC camera. So I have two options: Have the SWC modified (lower the tripod foot to give clearance for the back (and no, the EL-battery adapter does not solve the problem alone) or buy a cheap 40 mm C-lens (CF or CFE Distagons are out of reach at the moment).

Has anybody compared picture quality of these setups?

I have used an early Distagon C not even with T* coating with the CFV.
Results were quite good, I did not compare them with an SWC though.

The improvement with the later CF version of the 40 mm is mostly at the edges of the image.
Since the CFV does not use that part of the image circle the IQ of the C lens with the CFV back is very good.

Removal of the tripod foot of the SWD is not a major job though.
With some SWC cameras the foot was cut of near the body shell.
Not elegant but an effective solution.

Hi,
I am looking for an elegant solution and of course a tripod foot has to stay in place.

I was always tempted to cut off the extension to the tripod foot as I did not enjoy the L-bracket at all.

The SWC is a joy to use with the CFV and quality is excellent. Maybe a CFV-39 will tempt me to try again.

Is the L-bracket required with SWC/M or later cameras?

Alternative would be to drill a hole in my CFV back so that I can use it conveniently on the Hasselblad SWA ;-).

On my SWC/M you van see that the tripod plate is extended beyond the camera body and that's covered with a chrome plated plate.

The extension serves no purpose for me and my intention was to cut it off at the block. That wouldn't affect tripod use, but would make the SWC/M (now fitted with superb Voigtlander Angle Finder) infinitely easier to use as a street camera.

I sold my CFV because I was not happy with the crop factor and I needed the cash to purchase an Leica M9. I'm wondering whether the crop of the CFV-39 is more acceptable as the IQ from the CFV is preferred here.

The CFV-39 is not recommended to be used with the SWC and the following is from my own experience .

If you use the full sensor format (37x49) , you will get a magenta cast in the right part of the image and a cyan cast on the left part . The square part (37x37) shows the same quality as with the CFV-16 .
Even if you take a white balance shot additional to your image , you will not be able to remove the color cast by a 100% in PHOCUS .
Also you will not get the expected sharpness on either side .
You can of course use the "crop to square" function of the CFV-39 , but then , you can also use a CFV-16 back .

Thanks for that information, could save a life here.

If I did buy a CFV-39 it would definitely be to frequently put it on the SWC/M, so I need to be fully aware of the downside.

I'd booked a week long demo last month, but my current 203FE hasn't been modified, so it was cancelled. I have to pay £260 for the mod, or borrow a 500 Series, before I can test it. Think I'll be keeping the M9 and using film in the Hasselblad. :-( Don't get me wrong, film results are what I like best of all and I have a scanner to take advantage of it, it's just that I tend to elect for convenience far too often.

Using the CZ DISTAGON T* 4/40 IF/CFE + CFV-39 I receive extremely good results .
There is no color cast and the distortion can easily be corrected in PHOCUS .
The crop factor is 1.1
I can not speak for other 40 mm DISTAGONS .

The 40 mm IF lens is without doubt one of the best lenses ever designed for Hasselblad cameras by Carl Zeiss.
Like Jürgen mentioned the slightly bigger distortion can easily be corrected by Phocus.

This will be a sought after lens as soon as Hasselblad stops supplying these.

There is a used 40 mm IF for sale in the classified section!

You can use your unmodified 203 with Cf lens and CFV+ a wire.

I don't understand why the cfv has not the drilled hole for old Hasselblad.

Strange colors with SWC does not disapear with a pluged wire ?

By the way, impossible to use my 1000F with my CFV.
