Hi all,

I'm wondering how far you actually push the above mentioned lenses before you hit the infamous hard vignette disk.

These two lenses are my most favoured focal lengths and I would use them on my Credo 60.

In practice, I would like to know how far I can push the 70mm HR for 6x13 panoramic stitching, and it it'd be possible to get 17mm of horizontal shift plus upto 8mm of fall on the back, as pictured in the attachment here. This is where a lot of my work seems to sit these days. I know the graph (sourched from DT) represents the published limits, but wondered if in practice there's a little more give.

For the 40mm HR, I'm only interested in single capture so not concerned about doing such big shifts, but interested to know where the disk pops up vs. what the published limits are.

I'm also wondering what C1 is like in dealing with LCC shots where the hard vignette is visible. I know Phocus freaks out with it, so wondering if C1 can handle it and still enable you to process the LCC and apply it to a file (to perhaps crop it out later.)

Thanks,

TJV
