Not sure how you would tell the difference unless you have several copies of each of the same even then I'll bet they all come out within 5% BUT each system has dogs and winners. That you can get up to speed from users reviews, like Hasselblad 35 it's the dog in the line up!I been looking to decide which system to go to and it seems Hasselblad lens are older and is unsure who even updated them. Hasselblad lens is cheaper, faster, and lighter it seems. Phaseone lens seem extremely good but huge. Phaseone has slower flash sync speed too.

Either system would make great tools for your image making possibilities, however Apple says the IPhone makes great images too! Try before you buy.
Hasselblad makes two types of lenses HCD and HC. HCD lenses cover a smaller area than HC, they were designed to work optimally with the smaller 50mp sensor (H6D50c). Owners of the larger 100mp sensor (H6D100c) are saying that HCD lenses work very well with larger sensors as well, e.g. : https://nordhaugphotography.wordpress.com/2017/01/21/h6d-100c-and-the-hcd-lenses/I was told that some Hasselblad lenses are crop lenses which do not cover fullframe sensors very well. You might want to be careful with their wide angles eg HCD24?
This is true on the larger sensors. However, I own a HCD 28mm and HCD 35-90mm and have never found the amount of crop to be significant or limiting on my H6D-100c.I was told that some Hasselblad lenses are crop lenses which do not cover fullframe sensors very well.

Eric, the MTF curves CI posted are from Phase One / Schneider.
To the topic... anyone who tells you one line is across-the-board better than the other is clearly in sales.
1) "good" depends on use case. For someone who shoots shallow DOF portraits with longish lenses, someone shooting wide-angle landscape at f/11, and someone who shoots high magnification macro product shots the definition of "good" lenses will be drastically different.
2) Not every lens in a line is equal. A line of lenses always has lenses that are above-the-average-of-the-line and below-the-average-of-the-line. The best lens in either lineup is definitely better than the worst lens in the other. So the question is really less about the whole line, and more about the specific lenses you're likely to use. That's a far more nuanced question.
3) Weight, size, feel matter. They don't (directly) effect image quality, but if you tire of picking up a lens then you probably won't use it as much.
4) Tools of the camera matter. A great lens that you can't achieve focus on is not as good as a great lens that you can. A great lens + body shake = poor image. So tools like the Hyperfocal focus tool, focus stacking tool, vibration-avoidance mode, and quality of autofocus matter.
5) Service/support matter. For example IQ3 kits come with 5-year unlimited-shot warranties on all lenses purchased with the kit, including a loaner during any service/repair. The quality of a lens doesn't matter when you don't have it in your hands in working order.
Moreover depending on what you're shooting you may be asking the wrong question, and the best option may be tech camera lenses like Rodenstock on an Arca, or a crazy old lens with a weird look (much more possible on the XF since it has a focal plane shutter that can be used with lenses that lack a central shutter).
It is unquestionably true that Phase One has been on a roll the last five years releasing new and improved lenses, all of which were designed for full-frame 645. But which lens line up will do the best job for your use-case and for your priorities is something you should decide with your own hands on shooting.
We'd be glad to help you with that testing. Our test studio / office is in midtown Manhattan, a few hour train (our office is 10 min from Penn Station where Amtrak stops) or short flight away from you and we can also arrange rental-toward-purchase evaluations. Or if you can't get the time to do your own testing we have a test catalog of a few hundred gigabytes worth of test images with different lenses; some are available on our website (35mm, 45mm, tech camera), but most are available only upon request.
Finally, let me put a strong word in for real testing over reading MTFs. There are any number of issues with using MTFs to guide purchase decisions, and I'll just highlight one. Incredibly sharp lenses that have slight field curvature can score worse on "corner sharpness" MTF analysis than a mediocre lens with a flat field. If your use case is shooting landscapes at f/11 then slight field curvature is not a problem, while mediocre optics are. An actual shot of landscape with both lenses (preferably a series of shots where you set up from scratch several times) will tell you far far more than an MTF curve.
Hi Doug,
I tried to give some correct and relevant information based on what I have found and what I know after following Hasselblad since 1970 and Phase One since 2006.
I don't think that MTF curves I referred to are any longer available at Phase One home site. If you feel there are better data available, feel free to post a link. If you do so, please also explain the fundamental differences between the way Schneider presents data and Hasselblad does. I tried to do that, to some extent.
MTF data does not tell all about a lens, but it tells a lot. Foremost, lens designers calculate a lot of different sets of MTF data while designing a lens.
Best regards
Erik
Well you're half right. There are biased opinions.There are two kinds of opinions, the non interested (biased) ones, and the interested (biased) ones...
We all want a friendly atmosphere on this forum, but your original post was right on target. You have no need to apologize.I am user of products from both brands, for my personal work and also for some client`s studios wich I have been working for as a photographer, and also as intermediary between clients-shops-brands in the last 10 years.
First of all I apologize. It was not a personal message. I just wrote it to keep the marketing out, in sites I consider public and non commercial, like a forum. Sometimes marketing is everywhere, and we dont have any space to have a breath
I would like to say I have, of course, the best wishes for you and for your business, sincerely. I repeat, It was not a personal message, sorry.
For the biased consequences, after my message, I dont make any comment about the quality of the lenses, of course haha..
Regards and apologize for the off-topic
ciao

Actually, I like the HC 35. The reviews are negative because the lens lacks punch full open, but one rarely uses MF lenses full open so it is not a real problem. On the other hand, the HC 35 has pleasing bokeh.That you can get up to speed from users reviews, like Hasselblad 35 it's the dog in the line up!
