Another RZ67 Finder Question

[trace_dibble6]

Can anyone tell me how accurate (or not) the RZ67 eye-level prism finders are,

i.e., how accurate the borders seen when looking through the finder are to

what is actually recorded on the film? Thanks in advance...

Mamiya doesn't provide this data. I used both a waist-level and a PD Prism Finder on RZ Pro II bodies. IMHO, both finder/body combinations were about 90%-plus accurate (which is decent for medium format SLRs). That is to say, I didn't see notice a difference in framing accuracy as between the waist level and PD Prism Finder.

 

 

Mamiya advertises the body, presumably with a waist-level finder to be 95% accurate, which is, I think, a bit optimistic:

Trace, I have used the FE701 Prism Finder on my Pro II for about four years and find it better than 90% accurate. Exceeded my expectations. I also consider its metering system capabilities and LED displays to be fairly accurate, as in most cases when doing landscape I always compare to my Sekonic L-558 meter, the Bible for all my cameras.

Checking the accuracy of a prism or folding viewing hood is one of the first things to do when you buy a new camera.<br>

If you have a Polaroid back, it is much easier to do.<p>

 

Select a subject with geometrical marks, like a building with windows. Frame the building so as to have a complete window on the upper-left part of the focusing screen, and another complete window on the lower-right part of the screen.<br>

Shoot a Polaroid, and check if the framed subject is totally on the photo, or not.<br>

As you know the dimensions of the Polaroid film, (a <u>square</u> 69.5 x 69.5 image) and the dimensions of the focusing screen, you can determine the proportions.<br>
