Highlights and Shadow Recovery Tests:


On each I was trying to pull up as much as possible using ACR. I’ve used Adobe RAW converter because it gave me slightly higher range of adjustments over Capture One.  The quality of the output was the same from both.

Another Example of Leaf Aptus Dynamic Range  


Highlights Recovery Example: Not the Best From Leaf

Highlights recovery is not that impressive though. But there is always could be a level of overexposure when sensor frys pixels. May be one day we’ll have something like electronic iris on each pixel? this would be cool:-)



What Is Next:

Full in-studio test similar to Hasselblad and Leaf Aptus II I did a while ago.


P.S Speaking of the pricing of Medium format backs on eBay: Check this Hasselblad H3D39! Average selling price is around $6000, and this one was sold for $2900

  1. Many thanks for the excellent article. I have the chance to purchase a Leaf Aptus 75 for my Hasselblad V system. After watching your video I think I will make the plunge .. (it will allow me to get some more milage out of the Hasselblad equipment) Do you have any experience with the Leaf on older Hasselblad equipment. Any tips or suggestions you can give about using the back in the field.

    thanks again.

    Great stuff.

  2. I have Bronica ETRSi and wish to use the Leaf Aptus 75. What all do i need to work straight away , is just Aptus 75 sufficient or do i need extra accessories to make it work .Please reply with details.
    Thanks in advance

  3. thank you for your feedback, and keep up the good work, good light!

  4. I’d love to have a medium format camera!! I prefer Phase One with IQ back, it is my dream!!
    Except the resolution I’d like to see studio samples for example jewlery, how the dynamic range can help in such shoots?
    The biggest problem is that I have not so big clients to can get medium format, for the time deign I investing to 180mm macro and 4 -5 C stands with flags.
    Step by ste I am building my studio fro 2006 but it seems that the steps never stops !! I am also a gear geek :-)
