Here's a question. Is the word "Digital" a bunch of hog-wash when it comes to large format lenses? As long as the lenses are designated APO, is that not enough?
I posted this question here since I am P25+ shooter but curious about Large format possibilities with my Sinar. Thanks guys.

Hi Rudy,
I am having a custom made adapter be made for my Aptus 65 to go on my 4x5. Thus no real life experience yet to your question... however I have researched;-
1. Digital large format lenses are all medium format size, up to around 120mm image circle per what I recall. Thus they require more exact movements than 4x5, because you will simply use smaller capture area (film/sensor). In particular for wide angles where DOF (depth of focus) is very small it requires a technical digital camera. Both the lenses and such cameras are $$$. For very wide you may not need lens movements at all.
2. My personal aim is to use for landscapes and for stitching panorama. Thus I will use my digital back similar to film size; up to near 612 and sometimes 4x5. I personally believe this will work, but near future will prove me right or wrong.
3. Per email reply, per what I recall from Schneider, they said that an Aptus 65 is around borderline for their modern traditional lenses. I believe it will be ok with SHARP lenses for Aptus 65 which is a 44x33mm sensor and 28MP. For a 22MP 48x36mm sensor it should thus work fine, but no certainties.
Best will be to use sharp lenses, but there may be issues of diffraction at certain apertures. You will need a steady 4x5 camera also. Mine is a non folding Shen-Hao TFC45-IIB.
