Here is my experience with both Leaf and Hasselblad:
About two months ago I was ready to buy into either make. I was currently using two Imacon 4040s.
I called the rep from Hass in the UK and at the same time I called one of the reps for Leaf.
Both reps came to the studio within a week knowing that I had called their ribal and may the best system win.
The Leaf guy came first, there were some problems with the software or connection or both. The lens on a Rollei ControlS wouldn't stop down through the software, it had to be done manually, then half way through the demo it started to work. No-one knew why. The file was very good, but I was left thinking that the system wasn't reliable enough, so I waited for the Hass demo.
The Hasselblad demo was the biggest disaster I've ever experienced. I felt sorry for the rep, he is a nice guy, very helpful and so on, but the camera, which he had just opened brand new from the box, didn't fire properly, the 4-shots weren't implemented yet, the Life picture wasn't implemented, everything was embarrassingly not working at all. Tell you what, much as I like the rep, I was angry that Hasselblad would allow their cameras go on demos with the knowledge that they are not ready for customer consumption.
I wasted a day, I got really impatient and Hasselblad, (I had been using two Imacons 4040 for three years, which I really liked, as I like the Flexcolor software) was suddenly out of favour, they lost my faith and my custom. If they had told me, sorry, but the camera is not ready yet, so we can't demo it, fine, I would've understood, but how can anyone buy such expensive item on the premise that it will work one day, sure it will!
So, although my natural impulse was to go Hasselblad (the Imacon 4040 was at the time, and even now, quite difficult to beat in 4-shot mode), I had to see if the Leaf guy had updated the latest firmware which he assured me was the cause of the initial erratic behaviour.
So the Leaf rep came for a second demo. This time everything worked, the camera fired, the aperture stopped down from within the software, the files were great, the image was on the screen quickly enough and so on.
I went for Leaf, and I bought two Aptus 65 actually, which are incredibly good value, as the chip is only a couple of milimetres smaller than the A75, and I always crop anyway.
I still have some nostalgia for Hasselblad, but it's only by default, as I find the Leaf software completely behind times, it does the job, though (V8). I wish the Leaf software were as practical as Flexcolor (though Flexcolor updates have removed its simplicity much to its detriment, I think)
I am willing to give Leaf the benefit of the doubt and see if they come up with the promised software update (10.1). So far I am a bit disappointed that they have announced a delay (we were expecting something by Photokina) but my patience is not exhausted yet.
I have no loyalty to any make, they are all far from perfect, I feel that us photographers are being short changed, but we have no alternative but to chose from the small choice and make the best we can out of it.
