Pentax 6X7 transparencies duped with Pentax 645Z

Contrast has always been a problem when copying. Years ago there was a special flat piece of Photo Gray glass that a 35mm slide was laid upon and expised to light. This added density to the highlights and reduced contrast. It was finicky but seemed to work for printing on Cibachrome. Think it was manufactured by BAT Color.

Many people use enlargers as copy stands. Replace lamphead with camera body and locate light source on easel. This prevents using the camera's macro lens. But, my Beseler 4x5 enlarger has a Nikkor 135 enlarging lens. Wonder which lens is sharper?

I remember in the Hama accessory catalog a neat gizmo. It was a bright light that attached to the camera viewfinder. This projected the viewfinder on to the ruled copy board. It was supposed to help setup and position the photo to be copied. Hama is gone but it wouldn't be that difficult to turn a LED flashlight into one of these.

Thanks,

This is the first image copied. Haven't printed anything yet. I will have to work with this more
before being able to answer your question.

I'm here. Also using a DFA645 55/2.8 on the 645Z. Owned the Z for a month and the 55 arrived today. What better way to learn new equipment? Hope I can figure out how the picture posting works. It seems complicated. Shooting a picture every day but probably posting in batches, as time allows.

Thanks,

Thanks for the explanation. Since the 645Z is based on the K-3, it's surprising the screens are so different. I'm glad Ricoh puts the 100% indicator on their cameras it is useful.
Thanks,

Thanks for the mirror alignment trick. I will try that next time. Sounds a little like aligning reflector telescope optics.

I remember some 120 transparencies coming back rolled up in fat rectangular boxes. This slide was sent in strips of 3. Used a Beseler 4x5 enlarger's 6x7 neg holder to hold it flat. Glass would be even better, but Newton rings can be tough to conquer.

Thanks. Hope you try this if there are transparencies around the house.

This is my 1st attempt and reasonable care was used, but I can probably do a little better when everything is tightened up. The film was taken years ago with Pentax 6X7 and 75mm f4.5. Copied these on a light table using Pentax 645Z with A 120 macro. Even with levels it is hard to get everything parallel. Not bad for a first attempt. Any tips or comments appreciated

Not seeing the 400mm + 1.4 teleconverter example picture. Your 1.4 converter review has great info. Thanks for doing the research and posting. Any experience with the 2X?

Have 120 f4 macro, 80-160, and arriving soon the 55 f2.8. Is there any use for the tubes or converters on a 645Z? Or, are these photos better left to the K-1?

Quick 645D lens selection question?

For focal length coverage leave the 45-85 at home. The 33-55 handles everything up to 55. The 80-160 covers the 85 end. This leaves a small gap between 55-80. A few steps forward or back and a little cropping would handle that. It's always fun to pack and decide what gets left behind :).

No mirror lock up with live view

Will have to check if the mirror falls inbetween exposures. I'm used to the K-1 and just got the 645Z. I left the mirror lock up switch on lock. Using optical viewfinder all was well. Then I switch to LV to get more accurate focusing for a macro shot. The wired remote wouldn't work MLU. Thought the wired controller was broken. Then found out the wireless remote F wouldn't work either. Then I remembered reading the warning.

Does the 645Z have an electronic shutter like the K-1 or is every thing using the mechanical shutter?

Thanks,

Strange that the mirror lock up function doesn't work with live view. Seems it would be easy since the mirror is already up during LV.

Terrific captures. Snow didn't make these shots any easier. Grouse pictures are rare, nice to view something out of the ordinary. Glad you're back photographing and posting.

Excellent information. Sorry to hear of a Pentax battery swelling. Guess nothing's perfect. The price increases are quite a bit. Lots of lithium comes from South America & China. Perhaps the covid virus and other things have temporarily forced the prices up. Hope it's only temporary.
