"hmmmm. . . .since this line is very easily dealt with, all the leaf owners who experience this centerfold problem should quit complaining. . . .at least until leaf replace the defective sensors"
Except that one of the main selling points of the Leaf back was not having to shoot a plastic card with every shot. For me personally it adds another 30-60 minutes to every shoot day to shoot the extra images and then apply those corrections back at the computer.
I shot an annual report with a P25 earlier this year mostly untethered. It took alot of time to create an LCC for each setup and apply that to all the images from that setup at the end of the day. If I wanted to try an alternate composition by shifting up 3mm, I would have to shoot another LCC shot for that bracket. I have used a few Phase backs and have always seen the LCC issue with these lenses (sometimes it may only be a corner of a white room going 2 points magenta). It is a known and accepted part of using the Kodak sensor. Like dealing with reciprocity from the film days it is just something that Phase One users accept as part of the workflow.
The primary reason I now own an Aptus 75 is to avoid the Plastic card. I was willing to sacrafice the superior workflow of C1 pro, and the ability to shoot long exposures so that I could just walk out my door with my Alpa and Aptus 75 around my neck and shoot pictures knowing that the files would not need a LCC or gain adjustment.
Of course I have to appologize to narikin for officially hijacking this thread. I just felt that if Leaf does solve this problem, then the Aptus 75 will be a back that is better suited to a handheld camera like the Alpa 12TC with the wide digitars and HR's than the P45. Put the Alpa on a tripod and it may be a different story.
Also Narakin, There is a universal shoe that Alpa sells...http://www.alpa.ch/en/products/pictures/_l...tive0-25-25.jpg
This would allow you to use viewfinders from other cameras like a Cambo Wide, Horseman, Leica, Blah, Blah, Blah. You may find something more suitable for the normal to long lenses. Jeff at Fotocare is my Alpa dealer and he has been very helpful with questions like this. I'm sure Jeff at Badger is very good too.
