Thanks, hm. Already rigged up a loupe as a waist-view - wondering if the DW-1 will actually be an improvement?

The DW-1 offers only a little protection from light from the sides and lift the loupe a little further away.
Otherwise it is exactly the same as looking at the focusing screen with the prism finder removed.

F2 Head-related question.

DW -1 Waist Level Finder

"its projected image inside is reversed left to right but NOT top-to-bottom."

That's landscape format - what do you see as portrait format please: will the image be reversed + upside down?

Thanks

Se my answer above. You can use your current setup to answer your questions.

You put the camera on a tripod and raise it to eye level.
Then you rotate the tripod head so the lens is pointing to the subject and the finder is pointing sideways.
Then you stand to the side that the finder is pointing to and look at the upside down image to compose and focus.
It will help you gain an appreciation of the early portrait photographers
This image was done that way with a 6x4.5 camera - using its self timer:

I really should have had my hair cut before that day

Thanks Matt,

I typically use waist-view for crowd scenes, hand-held, ASA 125, using a Gossen meter as an aperture guide. In the studio I'd use the Nikon F2 mounted on a heavy tripod, but using the DP-11 viewer, which will give me meter-readings for tricky, macro studio-lit shots.

That looks like a turbine. My father used to work in a power station, I remember seeing things like that there

Just looked at your pic a second time, I think your loupe position is about the same as with a DW-1.
A little cardboard around your construction to protect the view from light, and you can use the savings for a lens (those DW-1s are pricy these days).

Cool, thanks - I was astonished how well that loupe fit.

My photos are random multiple exposure so, although composition is always important, exact placing of uprights and horizontals should not present too much of a problem. I found it practically impossible to 'line up' on anything, using the mirror-view, upside down, but I'm sure something interesting may come from this!

Which (macro) extension tubes will fit the AI system please?

Have seen several types/sets, some have AI ridges, some have none; others have a flange extending out from the rear of the lens.

Thanks

Here's a link to the KEH site for the PK13 extension ring in Ai. The photos give a good look at the Ai lever:

Yep, PK-11, 12 or 13 are AI-compatible. PK-13 is the longest, providing the highest magnification.

Thanks How do they work though - I can't see any ridge or notch on them to engage with the DP-11 light meter?

jimjm · Aug 9, 2023

AI lenses and other attachments have a raised ridge on the edge of the aperture ring, closest to the camera body. These engage the meter coupling lever on whichever AI-compatible body you are using. Extension tubes have a moveable ridge that's linked to the ridge on the lens you have attached. This transfers the maximum aperture setting to the camera's meter. This shot from Ken Rockwell's site is a good illustration (ridge at the bottom starting between the 16 and 11).

Yes thanks, I understand the ridge

Yes thanks, I understand the ridge - it's a pity there isn't a picture of the tubes though, how they engage. I'll look for the PK 11-13's

on the lens side of the tube there is a lever that is engaged by the lens' ridge. On the camera side there is a ridge that actually rotates based on the position of the level on the lnes side, that way wherever the ridge is n the mounted lens, the extension tube will move its ridge to the same place.

Many thanks - think I found some tubes - will update
