Now I'm getting worried. Does this banding occur when using these wide lenses on a shift that most AP's would use to photograph a building? I own a P45 and Phase 1 is going to give me double what it's worth as a trade in for the IQ180 but if I'm going to run into problems like this it might not be worth it.
that's my worries to - Phase have a really decent trade in for my A75, but as it seems now, nobody will have the chance to test the iQ180 on a technical camera before you have to sign up for the deal before 31.03.2010
I can only too easily remember the pain when I got my first Aptus 75 and it shows heavy centerfold.
It took 24 month before I had a back with no obvious centerfold. Leaf was helpful and in good faith on this problem, but it took a lot of testing and wasted time before we found a good sensor. Leaf Capture could correct the centerfold in most cases but not all, and you had to turn the light fall of adjustment up to 100% leaving the the file quite flat.
Well I can't speak for the Schneider glass, I have never seen anything like it from Rodenstock.
I have seen those lines on Schneiders AND Rodenstocks when shifting too far.
It was the same thing thing with the centerfold issue, some saw it, some did not.... it varied a lot from back to back.
So that's why I'm a bit scared about sensor problems with wide angels and shift - and 10mm of shift on a 35mm is not a lot in my world....
I do hope that phase enable some of the demo iQ180 for technical cameras, before I have to make a decision about the trade in, that are indeed very tempting, but on top also means two new mac pro's for the studio as well....
I know that there will be workarounds like, don't shift more than 8-10 millimeters and then correct in post - but, when I use my Alpa's I simply love to compose the image, apply the necessary amount of shift so I get that precise view of what I want to show of the building - no cropping, no perspective correction, no correction for CA, no distortion correction, (except for the 23mm Rodenstock, and I would like not to make that list any longer) in the post production
I like to choose the right light, make the final composition in the camera, make the exposer, move on to the next the image - the feeling of creating a beautiful images with a beautiful tool, I like that, a lot!
From a business point of view, then I should leave my Alpa's at home and only bring the Canon with the new 17+24mm shift's - they are good! and I can make 20-50% more images per day, which is not an unimportant feature in todays economically climate, but I miss the feeling of creating an images with the Canon, with them I'm just operating a camera taking a photograph - with the Alpa's I'm creating one. I know it's all in my head
So Phase; because the iQ180 is really so close in many fields - please tell me that I can shift the full image circle without any banding or centerfold or other abnormalities, and you get my money - a lot of them....
