Seeing Leica as well other manufacturers are bringing out new lenses with much improvement in resolving power (sharpness with great amount of details), field flatness and chromatic abbreviations correction (APO lenses) … I begin to wonder if for 8 x 10 print from smaller negative to outperform the same size of print from larger negative (no new lens has been developed for 120 film camera for years).
Carrying smaller and lighter photographic gears is always appreciated if no need to trade off quality of final print images.
I have not upgraded my 135 lenses to latest generation of APO lenses as I am still using my 120 setup (Mamiya 7) for film.
Would appreciate your comments or sharing of experience .
Your Mamiya 7 will always and forever hugely outperform (in terms of resolving power) any 35mm film system, no matter how great/perfect a lens is. The limit is the film grain. (A secondary point is the M7 lenses are already nearly as good as it gets, and modern lens improvements are incremental.) State of the art digital will out-resolve drum-scanned 6x7 negatives, but if you are working entirely with film then you are limited by the film grain. The difference between drum-scanned 135 and 120 film as seen on an 8x10 print, in my experience, is not resolution but the appearance of the grain in the print (you see it with 135, but barely if at all with 120). For bigger prints, the 120 scans will be even more dramatically superior (I always felt 17x22 was the sweet spot for prints from 120 film).
