Framing w cv25 Brightline VF

[gbb]

Hi,

I'm getting a lot more in the frame from my cv25 than I see in the brightline vf, so I want to know at what distance the bl frame is correct, and whether at infinity or even 3m I should be using the whole vf, not just the frame? Thanks.

I've often wondered if the lines themselves are included or excluded in the field of view. And with an external finder afixed you get no parrelux correction. so what appears to be the center of the frame may be a little off, right?
Forgot to mention, congradulations on the new addition to your family. Boy or girl?

Usually the lines are set for the close focus angle of view. At infinity you see see more than the lines show.

Mark up a target for 3,6.10, ft and infinity and see how paralax changes and how image size sizes. Frame the image tightly just inside the lines.

Perfect framing is best done with a view camera or reflex camera.

Same experience here. The 25 brightline finder is as narrow as the 28mm framelines on my HexarRF were. There is no distance where my brightline finder matches the CV25 lens, even not at infinity where the field of view is widest.

Framing error with any finder.

Framing any finder, actually.
My CLE has 28 and 40mm frame lines, that correspond with 35 and 50mm field of view at around 3m distance.
I know about the theory of field of view of a mounted slide, but a mounted slide is a little over 23x35mm. Not that much smaller field.
Same error at my brightline finders and other in-camera finders.

This must be a design feature I don't understand. 😕
