  1. Hi Everyone:
    Am interested in getting a Hasselblad CFV 39 or 50 Digital Back for my V Hasselblad Bodies and Lenses. I have numerous V Lenses. Stopped Shooting 5 years ago due to Health but now want to get back into it. Things have Changed. Do not know anyone who owns or has even used one of these Digital Backs. Maybe should get into the H Series but I Love 6 X 6 and would prefer V Series. Any Comments or Advice would be Very Appreciated Regarding these 2 Digital Backs.
    Thank You
  2. I bought a CFV-39 over a year ago and love it. The quality of the images is absolutely outstanding.
    I got it before the CFV-50 was introduced, and have never used the 50, so I can't compare the two.
    I use it with a 555ELD body, and that's a great combination. I can shoot tethered to my MacBook Pro in the studio and never have to touch the camera except to compose and focus.
    Hasselblad makes a program called Phocus that does all the processing you might want, including correction of optical aberrations for all the V-series lenses. It's free at the Hasselblad website www.hasselblad.com or www.hasselbladusa.com although you do have to register, which you should do anyway.
    Phocus also controls the camera for tethered shooting.

    "Correction of optical aberrations": I thought Hasselblad / Zeiss lenses would not have any ;-)
  4. All lenses have some aberrations. It's impossible to design a lens for white light that has none.
    Zeiss optics are much better in this regard than most, but they're not perfect.

  5. I have a CF-ii 39MS back and it's capable of some very impressive files. I compared it to a phase p20, a canon 5D2 and an Aptus 12 and the CF had more DR than any of them. You can find my posts with the results on the LuLa forum. I use mine on a Rollei 6008AF so can say anything about the V. I'm sure you'd be pleased with the back and the digital corrections for distortion, light fall off and CA are very useful in the hasselblad Phocus software - and yes you do need them. Don't forget that a lot of those Zeiss lenses are getting pretty long in the tooth. They were fantastic for their day of course, but film was more forgiving.

    Hi Leigh,
    Of course I was joking.
    I often use the Photoshop tool to correct some aberrations, with some lenses. (I am not talking of Hasselblad now). On the other hand, I have some lenses that never suggest me to correct any aberrations: probably not perfect, but close enough not to bother to correct anything.
    Well, I would have imagined that Hasselblad / Zeiss lenses were of this latter kind (close to perfection enough so that correcting aberrations is not necessary). Perhaps the very high resolution digital back really amplifies all defects.
  7. Good Morning Everyone:
    Leigh, Eric & Marco Thank You for Responding, Greatly Appreciated.

  8. Mike, you do understand that to shoot square with these backs that you will have a lens factor of 1.5? The sensor for square shooting is only 36.7mm which isn't much larger than a FF dslr. If you shoot rectangular, then you are still looking at a crop factor of 1.1, but also shooting more of a 645 format. (1.1 seems optimistic based on the sensor size of 36.7x49.1mm)
    Anyway, this wasn't mentioned and you may already understand this.
  9. John:
    Thank you for Responding. I knew about the 1.1 Factor but the Gentleman at the Store never mention the 1.5 Factor when using the 6 X 6 Format. If I was to use my 503 CXi Body in Vertical when using the 645 Format I am not sure it would be very Comfortable. Maybe I will try to rent the CFV back and experiment for myself.

  10. The 36x48mm sensors have an horizontal aspect. If you wish to shoot in the vertical mode, you have to turn the camera 90 degrees. Unfortunately, the 90 degree prism will not fit these cameras, due to the depth of the digital back and the drop of the finder eyepiece. Consequently, you have to use another type of viewfinder from the side of the camera.
    Really Right Stuff and Kirk make universal L-brackets, which facilitate turning the camera if you use an Arca type QR system (recommended in any case).
    The aspect orientation may be a minor inconvenience, since you need a tripod to get all the resolution available in these backs anyway. The CFV is still a viable option for using an otherwise obsolete "V" kit of bodies and lenses. However, it is a case for an "H" camera if you're starting from scratch.
  11. Unfortunately, the 90 degree prism will not fit these cameras, ,,,​
    Sorry, Edward, but that's not correct.
    The HC 3/70 and its later incarnation the RM-2 both fit perfectly. They were dedsigned for use with the 70mm backs, so they are longer than the other 90° finders.
    With a magnification of 4x they're also the most powerful of the finders, giving a huge image.
    I use the RM-2 with my CFV-39 and it works perfectly, supporting both landscape and portrait modes.

  12. That's good to know, Leigh. There's nothing wrong with these antiques as long as they are in good condition. I based my comments on the PM-90 and similar finders. Will the older finders fit on a 200 body with a meter finder in the panel?
  13. Hi Edward,
    I'm afraid I know nothing about the 200, so I can't answer the question directly.
    The two finders I mentioned mount in place of the standard waist-level finder on the 500-series bodies.
    - Leigh
  14. The HC-3 and RM-2 will not clear the viewfinder display in the 200-series cameras.<br>Nor will the shorter tubed HC-4/RM.
  15. Good Afternoon:
    Edward, Leigh and Q.G. Thank You for your Comments. I will look into the HC-3 and RM-2 Finders.
    Mike Zentena
  16. Don't forget the shorter, or rather normal length tubed HC-4.
  17. The HC-4 works well. I use it with a 500 c/m, the cfv-39 and the flash hand grip - good also for working in portrait mode.
