I have both Contax (with or without extra battery grip) with P45 and H3D39 and they are totally different. With Contax, the handle is a structure of the camera while on H3D39 it is a moveable part (the battery itself) so I will vote without doubt the Contax gives much more confidence when you hold and shoot the camera, and its ergonomic is simply superior. The H3D39 battery grip is designed with an angle only comfortable when you are actually shooting, not when you carry the camera - when you are not shooting. It gets worse when you consider usually H lenses are bulky and heavy.
On the other hand, I also have the old 6008 Professional with the rotational handle grip, and because it has very good locking mechanical and able to change its angle to get better gripping, is also a better grip than the modern H3D39. I hope the Hy6 grip is equal or an improvement over the 6008 Pro and if it is, I will without doubt think it is better grip than H system.
Thank you for the feedback. I have enjoyed the Contax system for years, and I hsvr both finders (not the new $800 WLF, but the original $300 one :-) )
I have found both comfortable, esp. as you say the Contax is very 'confident' in the hand
Abd one other feature; it is heavy but SMALL. It is actually a smaller feel on my hand than an old Kodak SLR/c that I assume feels like many larger digital Nikon/Canon SLRs.
I do see the enthusiasm of the the crowd for the new Rollei/H6y. However, as pointed out above can you use
V series glass
I have recently tested older Visoflex SM (L39) lenses with the Contax/P45 and the image circle is 6x7
I think the short registry difference of Contax (64mm) opens to a whole world of glass that Hassy and Rolly miss out on
But I must say, this system, IFF, and that is big IF, it has access for the Phase backs seems to be thinking right,
Is that still an open issue? the Phase backs???
