Have RF lenses had their day ?
9 months ago

Leica lenses, as Karbe admitted in a recent interview, follow the same design pattern they always did. This is an uncorrected rear element structure, where correction was not required due to the thickness of film emulsion.

this has meant that the digital Leica's have to have an extreme combination of angled micro lenses and software fringing correction.

With a fully corrected rear element, as Sony aptly demonstrated in the RX1, corner issues can be eliminated for a flat sensor.

although the A7(r) does have a combination of software and micro lens adjustment(in the case of the A7R) it seems that correctly designed lenses, like the 55mm, deliver spectacular results.

it greatly surprised me to see the Sony Zeiss 55mm easily eclipsing the Leica 50mm Summilux in all aspects:

Also the performance of the Otis 55. Not only does this indicate that the modern "digitally designed" lenses are superior, that Zeiss appears to leading he pack of current lens design.

given the cost of Leica lenses, the nasty field curvature seems not worth it, especially with FF digital cameras.

i understand people with collections, and seeing the clarity of these lenses with smaller sensors, like the OM-D , Nex and Fuji series, but I am struggling why I should keep my 50mm Summilux asph ?
