PENTAX 6x7 Pentaprism Finder

Introduced for the original PENTAX 6x7 but also fits the 67 and 67II.

This is the standard eye-level view finder for the PENTAX 6x7. Extremely compact, it provides large, bright viewing despite of its size. It weighs only 480 grams. It provides a view of 90% of the focusing screen.

This viewfinder has no built-in light meter so the use of an external lightmeter is recommended.

Review Date: December 7, 2013 I can recommend this item: Yes | Price: None indicated | Rating: 9 

Pros: Well built and accepts eyepiece attachments. Includes “ASAHI” on front.
Cons: Prism blocks 10% of the focus screen, a bit heavy.

I got this standard 6x7 prism as part of a kit, along with the MLU 6x7 and 90/2.8 LS lens.

The build and finishing are very good.

Unreversed laterally correct image.

The standard 6x7 Prism accepts the Magnifier, Right Angle Finder, Eyecup and Correction Lens as attachments. (Same as the metered TTL prism)

Only 90% of the focus screen is visible when using this prism, so keep that in mind when composing a shot.

A bit on the heavy side.

These older prisms may need a seal replacement, if it’s a loose fit when attached to the camera body.

I use this prism when hand holding my Pentax 6x7 and meter with a Gossen light meter. This original 6x7 prism is the same as the newer ones, other than it has “ASAHI PENTAX” on the front. For sentemental reasons having “ASAHI” on the prism makes it my favorite, the newer ones just have “PENTAX”.

As I bough this prism as part of a 6x7 kit, I have not indicated a price for it.

Review Date: September 29, 2010 I can recommend this item: Yes | Price: $85.00 | Rating: 8 

Pros: Rugged, Clear
Cons: 92%? view

My version is as pictured. I got it with a big ding on the side, but it works great. My only negative is the fact that is seems not a full view so if I need the max frame area, I need to do a little bobbing.
