my rangefinder is out of alignment 🙁
not good

not sure how people define vertical and horizontal

when one focuses the lens, the patch moves left and right until it lines up

my patch moves left and right (i suppose is this called horizontal???) but does not line up images at infinity
i tested it by aiming at a pole or vertical object miles away

please help
thanks
 
well - which rangefinder do you have? Many have different methods to align the rangefinder.

As for the vertical/horizontal alignment question - I'll have to let one of the techies here answer, as my own understanding is a bit sketchy. (I only adjust the horizontal on my Canon P, I am not sure how, or what the vertical does other than make it easier to focus).

Making it easier to focus is a fairly big deal, so here's how to adjust the vertical alignment on your Canon P (or similar Canon RFs):

-- Removed the knurled trim ring around the round RF window. The ring just unscrews.

-- With the ring removed, you'll see that the round glass of the RF window has a slotted metal collar around it. This front glass is actually a prism that allows you to adjust the vertical alignment by turning it.

-- Using a pair of tweezers or other tool that fits the slots in the metal collar, turn the collar clockwise only to move the RF image. You want to turn it clockwise only because the collar screws into the frame behind it, and if you turn it the other way you might accidentally unscrew it from the frame.

-- Turning the prism actually moves the image in a circle, so your horizontal alignment will change as well as the vertical alignment. After you get the vertical alignment the way you want it, go back and reset the horizontal alignment in the usual way (using the tiny screw behind the chrome cover screw near the corner of the viewfinder window.)
 
The Bessa R3a, r2a, r3m, r2m, and probably the r4 all are just like the Epson Rd-1 when it comes to RF alignment. See the Epson RD-1 Forum for two recent threads with photos and diagrams for the procedure.
Long story short-
Take the thin metal plate off that is the bottom of the hot shoe, under that are some holes, which reveal the adjustment screws.
There is no optical wedge on the R types as outlined above for the canon/leica/fsu procedure, perhaps on the bessa T types.
