Hasselblad has the best camera if you don't think about the Rollei hy6 II.
The Rollei has different prism finders also. Brighter than both the DF and Hasselblad H.
And the AF is the best in the MF-world.
You can read of the Hy6 story, and of details of the system here rolleiflexpages.com.
Recent at Photokina;
Hasselblad - made lots of rumble of something complete new, and delivered improvements in same old body with now metal panels...
Mamiya/PhaseOne camera - even more mediocre improvements in DF+, and to chock for all in much same old clunky body as was AF, AFD, AFDII, AFDIII, DF...
DHW announced Hy6 Mod2 and
that they had been given rights
to further develop the camera!!!
Of above, Hassy and Mamiya/PhaseOne ask you to sell off what you have and come with fresh $$ to buy a new body. DHW simply offers a reasonable upgrade for existing camera to internals of
Hy6 finders? I very much enjoy the WLF myself. I have also tried the 45 degree and 90 degree finders. The 45 degree is the brighter of the two and with larger view, but not same bright as WLF and not same large view. I also suggest to consider... the less high you need to lift camera, the more steady you can hold it, which I have found very important with an 80MP back. If not WLF, I would suggest the 45 degree. However, the WLF comes with the camera... so you could give it a go first and see if you like it, or not. It does make more compact... Regardless, there are choices.
Hy6 ergonomics? Best handling and best balanced medium format camera for digital back. Period.
Hy6 AF? I find it very very precise. Nope, it is not DSLR quick. Arguably much more precise. Funny, what was that in above about Mamiya three focus points??? Another Google search by Fred??? I had AFDIII and DSLR in past. DSLR has many focus points, sure... care to tell me which one focus on that eye??? With Hy6 the focus area is a tad larger than DSLR, but very very precise. The main difficulty in portrait and high resolution back is to focus precise at same plane as the pupil in eye
when using shallow DOF. Else focus will be somewhere else (e.g. eye brow) and pupil will not be sharp.
For Hy6 there is option of new Credo back or the AFi-II backs. The Credo offer the iPhone like interface, but the AFi-II offers rotating sensor and tilt display. Mine is AFi-II 12 (80MP) and I much enjoy both rotating sensor and tilt screen.
Hy6 = one of best cameras I have used period.
Rolleiflex lenses = 80/2.8 Xenotar is glued to my camera, best wonderful character lens I have ever owned, very sharp and lovely out of focus and shallow DOF.
... my 50 FLE is likewise top notch... heck all recent Rolleiflex seem to be so, and close or on pair with large format digital lenses!!!
Sold in States? Important? You can buy factory direct from Germany. My contact at DHW is direct with CEO for service and support..., yet check with Capture Integration in States. I believe they are looking into it...
Leaf? I much enjoyed the image quality of my prior 28MP Leaf Aptus 65, but for landscapes it was something missing per my eye as far as colors and ability for transition into highlights, thus I maintained using also some film. The image quality of Leaf AFi-II 12 has made me drop film. Pixels aside - it is significant better than prior backs, more correct colors, more pleasing rendering of colors, finer gradation of tones, broader DR, more shadow detail, better shadow response... and I assume the more pixels help. 80MP means you can crop for image within image. These said, I am yet to upgrade to Capture One 7, which should improve these even more.
Compared to Mamiya? I never liked ZD camera, AFD, AFDIII, but did like Mamiya 7. The 645 lenses? Had 45D, 28D, 300 APO, 55-110, 35AF, 105-210, 24 Fish, 80/1.9 and more. The one I liked was 80/1.9, but my Rolleiflex Schneider 80/2.8 using larger sensor blows it straight out of water. Want more shallow DOF for up close, add extender ring. Works great.
I hope above helps
