For more thoughtful photography I like the process using legacy primes and using manual focus instead of using focus by wire offered by the native m4/3 lenses, this despite that maybe the native lenses offer better overall IQ compared to the legacy lenses. I've used various minolta rokkor lenses (mostly 45/2 & 58/1.2) mainly on my E-PL1 buy also occasionally on my EM5 or EM1. However lenses such as 58/1.2 becomes a tad long on m4/3 and given that I usually stop them down one stop to reduce the ghosting, I was considering either getting a speed booster or an Sony A7. This would make the 58/1.2 closer to a 85mm equivalent portrait lens and as I can move closer to the subject to keep the same framing, I can reduce the DOF giving a decent background blur. The main attraction by using legacy glass is the tactile feeling using MF glass and the more shallow DOF offered by my 58/1.2 for portraits. The price of a speed booster for Minolta MD to M4/3 is around 30% of a used Sony A7. I'm wondering if it wouldn't be better to get an A7 as a platform for legacy glass instead of getting a speed booster for my limited selection of Minolta glass. Ofcourse, I would be able to get 3 metabones speed boosters for the price of an A7 but there's still a significant difference in crop factor and DOF. Has anyone else done had similar thoughts and if so, what conclusion did you draw?
