Is there parallax correction when using an external finder? Is there compensation for distance from the subject? What is your experience with esternal finders & parallax correction? Thanks.

Huck,
I can't answer for the Rollei, but my Yashica's two auxillary lenses have distance correction marked on them. There is the external finder that fits in the flash-shoe to show what area will be included in either Wide or Tele, and then using the regular parallex focus, I check the distance and correct per the markings on the aux. lens.
Don't know if that helps, I'm sure more experienced RF'ers will lend you their advice 🙂

I am not sure about other auxillary view finders but I have a 28mm to 135mm Carl Zeiss Jena turrent viewfinder that has correction for infinity and one or two closer distances depending on the focal length of the lens. For Example at 85mm (8.5cm) The settings are Infinity, 7 feet? (maybe meters now that I think about it) , and 3.5 feet or maybe meters.
My Carl Zeiss Stuttgart 21mm viewfinder does not have parallax correction. I can't imagine why it would need it anyway.

The CV 90mm finder is their only one I think with adjustable parallax control. You dial-in the focu distance on a rind at thr finder's rear, causing it to tilt up or down.

Huck, some old Canon, Tewe and other external finders have a distance ring which tilts them to compensate for parallax error.
However, there was a great system into the Canon VT camera which tilted the external finder via a pin in the shoe to correct parallax error: http://www.cameraquest.com/crfvt.htm
It was a great idea and too bad it didn't find its way into the modern Canon bodies... well, the 7 has no shoe at all, so the pin is a secondary thing there 😛

Huck, to my knowledge the answer is no. Some of the CV finders, like the 21mm, have a faint second line to use as a guide when you are framing an object close to the camera. It is an approximation though, and not a true correction.

Huck, have a look at the viewfinder section at cameraquest, it has some info on parallax issues near the bottom of the page.

I know there are a few finders with parallax adjustments but only one I've seen in the flesh in the soviet turret finder. Some of the VC finders have an extra set of fixed lines in the finders... to quote from cameraquest section on VC finders........it has no manual parallax compensation -- but it does have parallax compensation marks in the finder. The lower dotted brightlines indicate the approximate view at about 3 feet. The upper solid brightlines indicate the approximate view at infinity

Parallax is more "acute" with telephoto lenses. The parallax error is "essentially" multiplied by the magnification of the lens. Wide-angle lenses have little error, but Telephoto lenses require some correction.
Most older finders allow the distance to be dialed in to correct for parallax. So you have to focus, read the lens scale, dial it into the finder, compose and shoot. Unless the subject is close, I do not bother with dialing in the distance but leave the finder set to 10' or so. Some (older mostly) finders use a cam to move it up and down, against a spring. Make sure the spring is strong enough, and you do not accidentally push the finder forward while composing. You do not need to ask me how I learned that one.
