Full Frame / 36x24 Sensor Format

Pros of Full Frame / 36x24 Sensor Format Photography compared to smaller Sensor Formats

35mm (135) Look:
With same format like the 35mm (135) Film, the pictures look lens-wise like "since ever" with those.

Cons of Full Frame / 36x24 Sensor Format Photography compared to smaller Sensor Formats

"None":
Only the "being always with you" smart phone has in that area an advantage, non other system can beat.

My Conclusion(s)

The Sweet Spot:
The Full Frame / 36x24 Sensor format is in the sweet spot for costs, size, handling, weight, resolution, low light performance, etc. for generell purpose cameras and lenses.
