Hi Rob ... The original thread went off on DoF. As you said, the original issue was whether or not there was any difference in AOV or perspective. All else was irrelevant to me when first posting the question, and, while the DoF issue may be of some interest to some people here, it's not to me. Anyway, I wouldn't know how to design a test for that ... that's more in your bailiwick ;-))
I'm more interested right now in another aspect of this. Early on I noted that the image seen through the istDs finder looked smaller and seemed "further away" than the image seen through the SLR I was using. I believe it was John Francis who said any perceived difference would be the result of different viewfinder magnifications. OK, I'll accept that. But ... the view of the scene through the istDs finder showed things to be smaller and further way. Both of us commented on that on Saturday when we were conducting this test. However, the magnification of the istDs viewfinder, according to Boz's site, is .95 and the % of view is 95%. The K-body camera has a .88 magnification @ 93%. It would seem that the view through the finder would appear closer, or larger, when using the istDs. What's up with that?
