I am currently researching my options for a high resolution digital camera scanner primarily for my 4x5 film, but ocassionally for 8x10 film.

Another user on the forum here suggested that I look at the Panasonic Lumix DC-S1R mirrorless full frame camera because of its astounding pixel shift technology.

I think this camera could be in my future for my scanning my large format film, but I don't seem to see a true 1:1 macro lens available?

So, this brings up a couple of questions:

1 - For 4x5 sheet film, is there a preferred focal length? I don't own any digital cameras, so I can't test.

2 - Do you know of any 1:1 macro lenses available?

Any input or ideas for building a high-resolution film scanning system is welcome.

Thanks

Larry
