i have seen impressive photography done for movies by dop´s like michael ballhaus shot on the rather small 35mm cine format so maybe the format is not too important at all...The A7rii is certainly an interesting camera with a high possibility to rip a decent share of the MF market but all the time the sensor is 135 it'll miss a certain look and feel to the image.
Hi Alexander,Thanks for the comment so far. I've managed to find some raw files to download and have to say I'm astonished by the quality of files from the 645Z!
If the profiles fully correct geometric distortion of the prime lenses based on focus distance and the zoom lenses based on focal length as well then I'm sold. I'm surprised though that no one else seems to have mentioned or discussed this. Again in something as simple as the attached shot, the residual moustache distortion from the Leica S 24mm lens is noticeable and disturbing.
Can anyone with any experience with the following lenses provide any information on how good the lens profiles are? 25, 28-45, 45-85 FA, 55, 75, 90, 120. I know everyone jokes about shooting brick walls to test lenses but as an interiors and architecture photographer I do strangely do find myself shooting brick walls!
Thanks
Graham, only if you must have the Leaf back. If you buy the Actus DB+ piece parts, eliminate the kit back and buy a CFV-50c (essentially the same as the Leaf) you would save $4K. Now THAT would be a deal.That is quite a deal!!

i never experienced connection problems with the sony but i use right/left angle connectors like http://www.amazon.com/StarTech-com-Micro-USB-Cable-UUSBHAUB3RA/dp/B001AR4NC8
Hasselblad has had a 200 mpix camera for some years now (multishot) and the people using it do not complain that the lenses are not fit to that resolution.Unfortunately I don't think Hasselblad ever expected digital backs to become so large because 50MP is pushing the limits of their lenses.
I'm glad to hear that Jerome but do you have any personal experience using the 200MP multi shot?Hasselblad has had a 200 mpix camera for some years now (multishot) and the people using it do not complain that the lenses are not fit to that resolution.
While LuLa has great reviews concerning usability etc, I don't trust them much when it comes to pure technical image quality analysis. They've had some strange claims through the years, such as DSLRs have 6-7 stop DR and MFDBs 12-13 stops. Multishot is much about getting rid of aliasing artifacts and I think you need to appreciate that specifically to like it.Michael Reichmann did a comparison between the Hasselblad H3D 50 II multishot and Phase One P65+/645AF in 2009 and even then concluded that in single shot mode the P65+ was vastly superior and in multshot mode the H3D only just managed to beat the P65+.
I've been working with multi shot technology since its inception (over 13 years) including working closely with the Sinar importers. I've used Sinar and Leaf multi shot backs on rail/tech cameras as well as the Sinarcam which had lens boards for 35mm and medium format lenses. I believe I have sufficient knowledge of multi shot technology.In the D800e review if I remember correctly mr Reichmann claimed that there is no aliasing issues despite no moire filter and if you think that you probably are not in position to appreciate multishot.
No, I use an H4D-50. But I gather that we would know it if lenses were not usable on the multishot backs.I'm glad to hear that Jerome but do you have any personal experience using the 200MP multi shot?
In support of my opinion, Hasselblad haven't updated their lenses (except the 50mm) since their release in 2002 (13 years ago!)
Of the ones you've mentioned I only have the 55 & 120mm. The 55mm is decently sharp, but the outer parts of the image circle suffers from lots of plane curvature, which many people immediately react to as being soft. I suppose that effectively it may as well be so.Can anyone with any experience with the following lenses provide any information on how good the lens profiles are? 25, 28-45, 45-85 FA, 55, 75, 90, 120.

Here's an image I shot at f/8 and the red circle marks where the building stops being sharp; the transition is fairly obvious up close.
I can't say much about the 120mm because I seem to have a bad copy of it, as it's considerably less sharp than my 150mm at any aperture; it's still fine for the macro stuff I do, so I'm not in a hurry to replace it.
And here's a 100% crop of the far left detail just outside of the red circle, followed by the second one just inside of it.Thanks, thats much appreciated. That's exactly the kind of subject matter I'm likely to be shooting so it's very interesting to know.

Many lenses are more recent than 2002:
HCD 28 (2006)
HCD 35-90 (2008)
HC 50-II (2010)
HC 120-II (2010) and
HCD 24 (2012).

I was shooting freehand, so it's not as overall sharp as it could have been, but you can still tell the difference.
The ground was sharp out to the corners which is why I believe this to be curvature, maybe if I had shot at f/14 or even f/22 I could have alleviated this, but had no tripod with me at the time. You can always square-crop your images
