How bout M4/3 to SLT? Can I share experience?
Anyway, I have been Canon shooter for almost 10yrs, but switched completely to M4/3 last year when I need a small camera when my son was born. My DSLR occasionally left at home since I have to juggle between baby & huge diaper bag. Seeing I rarely go out for photo hunting anymore, I decided to retire my entire Canon system & switched to E-P2 plus a couple of manual glasses.
E-P2 is a very nice camera, in fact my favorite. Great retro design, lightweight & able to take great shots, I didn't miss my DSLR at all. I have no issue with its slow AF, as I use manual lenses most of the time. It was great fun, a far cry from lugging heavy DSLR + L lenses all day.
But almost a year later, hands started itchy when I was getting tired of the low light performance (above ISO800 always need heavy clean up), low dynamic range & shutter lag. My requirement is the camera must be very small & lightweight, but have much better IQ than the M4/3.
Then Sony releases Nex, I almost jump into it, but I decided to give it a miss cause no EVF (which is very important for me), dumbed down UI and weird design. After that came the SLT and it sent me packing my M4/3. It really is tiny, fully featured & from IQ perspective, its an upgrade from my E-P2.
The prospect of being able to use the entire range of Alpha & legacy Minolta lenses is also exciting if I want to use it for more serious photography. On M4/3, you can only use the existing Olympus 4/3 lenses that are CDAF compatible, which are also very slow. The fast full time PDAF video also is one of the main consideration for me, since I frequently video my family. Manual focusing on hyperactive toddler is not very fun. :sweat:
Anyway, until others have come up with better mirrorless cameras, I'll probably stick with A55 for a while. Got it about 2wks ago & absolutely loving it. Altho I must say it looks cheap & ugly next to the elegant E-P2, but its the outcome that's more important...so...
