APO clearly has better micro contrast. For people who are willing to pay 6x the price, I'm sure this is the diminishing return they're looking for.
The design of Loxia 50 is an adaptation of ZM50/2. The calculations are revised to optimize for the A7 sensor. ZM50/2 performs on a similar level as Cron 50 v5, except that ZM has slightly more barrel distortion. I guess the Sony/Zeiss solution is to correct this by software. In my personal experience, software correction of lens distortion may sometimes create ungainly effects, especially in portraiture. I guess this is also the reason why, when requirement for image quality is high, fastidious photographers still use optical tilt/shift rather than software to create a similar effect.
Leica is caught out on one thing though: 50 APO is not really APO. Just look at the chromatic abberation. |
