I wasn't dogging any other system. I was just stating some facts about Hasselblad lenses so there is no need to get all defensive about your Mamiyas.
As far as weight differences there isn't much between the Hassy and Mamiya D ones... If you can physically feel the difference of a couple ounces or a pound then WOW! That is quite the skill you have yourself there.
Mamiya 28mm D = 1.9 lbs // Hasselblad 28mm 1.87 lbs.
Mamiya 120mm D lens which is manual focus (says their website) = 1.8lbs // Hasselblad AF 120mm lens 3.1lbs
Mamiya 75-150mm D = 2.5lbs // Hasselblad 150mm = 2.13lbs
Well while we are stating facts let's be complete.
Hassy 150mm 2.2 lbs - Mamiya 150mmD 1.7 lbs
Hassy 120mm 3.1 lbs - Mamiya 120mmD 1.8 lbs
Hassy 80mm 1.0 lbs - Mamiya 80mmD 0.7 lbs
Hassy 50mm 2.1 lbs - Mamiya 45mmD 1.1 lbs (55mm @ 1.0 lbs)
Hassy 35mm 2.2 lbs - Mamiya 35mm 1.1 lbs
Hassy 55-110 3.6 lbs - Mamiya 75-150mmD 2.5 lbs
In addition the Hassy mid-zoom, 35mm, 50mm, and 120mm are all significantly longer/larger than the Mamiya equivalent which moves the weight forward and off-balance of your hand (the 28, 80, 150 are all similar lengths).
Lens design is multi-faceted. Focal length, number of elements, maximum aperture, lens circle, and construction material size, and whether you include a shutter all contribute to the size and weight. Between Hassy and Mamiya one of the most significant differences in the size/weight is due to the inclusion of the shutter and it's impact on the design of the lens which is most notable on the 35 and 50mm lens where including the shutter greatly impacts the location of the rear elements of the lens which are preferably placed very close to the mirror box to avoid needing a higher power retro-focus element.
have fun correcting your lens distortion, APO, moire and vignetting on your own while I have Phocus take care of it all for me with the click of a check box.
Did a Hasselblad sales guy tell you that Hasselblad has lens corrections and Capture One doesn't?
In fact Capture One includes lens correction (distortion, APO, vignetting, purple fringing etc) for the Mamiya/Phase lens line, Hasselblad HC and Hasselblad classic lenses, as well as several Contax lenses as well as customizing the corrections for generic lenses (e.g. for dSLRs). The anti-purple fringing has won us many Leica users since certain lens/M8 combinations result in a lot of purple fringing. The only difference is that in Phocus you click a box, in Capture One you select your lens from a small pull-down. Once selected you can copy-paste that adjustment to some or all of the images in the folder in literally a few seconds.
If you are not and established professional photographer, it might be difficult to get a retailer to lend you a demo unit.
Where are you?
You could offer your services as an assistant to someone on the forum local to you... or are you local to a retailer on the forum?
We are located close by and would be happy to have you come to our studio with a model or still lives etc to test the system in a real-world situation for free. After if you're pleased with what you see we can rent you the system for a longer period and credit 100% of the rental to your purchase if you end up buying.
