After I had times with G7 and GX8, Oly bodies looks like... slow. I mean, slow by performance-wise. I played a bit with some Pana bodies while I'm in camera shop to buying some cleaning stuff. And I discovered they are extremely fast. Especially G7 and GX8 are outstanding by operation speed and single AF performance standard.(I used same single 1 area small target AF setting for compare) They acquire focus literally instantly. It's almost like they know already when I gonna press the shutter button even before I tap the shutter. It's not that current olympus bodies are sluggish. They are very fast in their own right. I like my E-P5, and it had rarely disappointed me in real life usage. Anyway mine(P5+25mm) was faster than much more expensive D810 + 50mm 1.8G combo when I compared it, so no really complaining here. Nevertheless, latest generation Pana bodies are just too supreme to be ignored. G7 makes latest Olympus cameras looks like slow performers relatively. I almost convinced to go for G7 there. G7 was faster than E-M1 when it comes to switch on to shot, and S-AF. It was my impression at least(I didn't checked firmware version on displayed E-M1.) and that's indeed impressive performance. I didn't know just operation performance can impact user's experience this much. I'm likely to give a serious look on pana cameras for my next purchase. Hope Olympus can manage in this regards for their upcoming new cams. I'm not an expert of digital technologies, but if computer's performance is related to its physical dimensions, I think it would be interesting to see vastly faster E-M1 mark II with cost of more bigger and heavier body.(well, just like flagships from C and N) Now we have 3 segmented in OM-D lineups, and they need to be more distinctly diversified by performance and compactness. For example, super fast and big E-M1, light E-M10, and E-M5 at between. Integrated vertical battery grip and more rooms for faster computer, does it sound? Can we accept "big and heavy" micro 4/3 flagship cam for cost of super performances? EDITED : corrected typo.
