Justin,
There are some that prefer the image quality obtained with the 22MP system(s), not to mention the 22MP sensor is noticeably larger, (ie. 37x49mm as apposed to 33x44mm), allowing for improved wide-angle performance. Also the 22MP sensor does not incorporate a micro-lens array, making it ideal for use with view cameras and super-wide / technical cameras. Options are always nice!
As always, I suggest any one with specific interest to call or email directly, so we can discuss final pricing, logistics, and details.
Regards,
Jordan Miller
Not to sound mean, but why would you pay 15k for an H3d2-22 when you can pay 17 for an h3d2-31 with an 80mm lens?
