Using A Right Angle Finder

A guide to using a right angle finder on your Pentax SLR.

24/02/2012 - 00:00

We often restrict ourselves to take photographs from a comfortable angle, but sometimes a lower viewpoint is much better. The right angle finder will make it easier for you to take more dynamic photographs from the ground looking up.

What is a right angle finder?

The right angle finder is an optical gadget that slips over your Pentax camera's viewfinder eyepiece.
It allows you to view through the finder in a more comfortable position, so you will be looking down rather than having to place your ear to the floor to see through the finder.

How a right angle finder works

The finder has a prism inside that bends the light, but the view on some is laterally reversed so it takes a little while to get used to fine adjusting the camera position. The benefit is you can shoot from ground level and see the subject from a totally different and more creative viewpoint.

Some right angle finders have magnifying lenses built in so the view becomes larger and easier to focus. Some have a switch to go from a standard view of 1x to a magnified view of 2x or 3.3x. They also have a diopter adjustment so photographers who wear glasses can use them.

What right angle finders are available?

The Pentax option is called the Ref Converter. Over the years Pentax have made several versions starting out with the original one used on the 60s Spotmatic cameras called the Pentax Refconverter that also fit the K1000 and KM. Then the Refconverter II that fit all K mount bodies, followed by the Refconverter M (below) that shows a corrected image and has 2x magnification. This one fits M and A series film cameras and modern digital SLRs.

Pentax Refconverter M

The current Refconverter A (below) is the same as the M but has a broader field of view to ensure the LCD below the viewfinder could be seen in the Program Series cameras.

Alternative brands include Seagull (still made), Jessop and Ohnar (both discontinued a few years ago). There are also several Chinese manufacturers selling direct on eBay.

With your refconverter in place you will find it easier to take photos like these:

I have a Pentax right angle view finder that I use with my Pentax S1a. Unfortunately, it does not fit the viewfinders of the Pentax digital range of cameras. The seagull viewfinder and the ones from china have plastic mounting plates and break.

Very smart technology at work here. In photography and image editing, it's often difficult to decide what the best angle is for that upright look. Depends on depth and the dominant figures in the frame. A mixture of art and science I'd say. Would be interested to know how the algorithm works.
