After Leica announced the new Leica M-P type 240, many have asked the question of a potential upgrade from the previous M 240. A reader contacted Leica Camera AG and this is the response he got:
The Leica Camera AG is planning to offer an upgrade for this model M as well. This gives our M (Type 240) customers the opportunity to equip their camera with various features of the M-P (Type 240). Please be advised that neither the 2GB buffer storage nor the frame selection lever can be upgraded.
Detailed information regarding the offered conversions as well as the costs will be provided in time. We estimate that this service will be available to all interested customers in the second quarter of 2015. Starting immediately, we are offering all customers who are already interested in an upgrade at this time, to collect their contact data and inform them as soon as the service has been activated.
