8x10 is still the best IMHO.
Just the look of the lenses is hard to beat.
A friend of mine with deep pockets and is a director of photography working with state of the art still and motion picture
digital still prefers a 4x5 film camera to anything digital out there. Actually I know quite a few digital directors of Photography that
shoot film for their stills.
You can also consider film as "digital". There are many advantages to shooting film and then taking it into digital post.
It's also cool to shoot hifi with fine grain film and then throw in a paper negative and shoot a totally different look
with the same camera.
I am also experimenting with direct to positive paper. Each image being unique. Interesting in the fine art world.
