This is going to be a long post so before I begin... some background... I started in digital photography with a Rebel XS then moved to a T2i with a 24-105mm, 70-200mm f/4l, 50mm f/1.8, and a sigma 10-20mm. I found myself most happy with the 24-105mm + 50mm combo for traveling although the 24mm wasn't really wide enough on a crop body but the long end was pretty good enough. I decided to take the m4/3 plunge because I figured a 10 day trip across Italy would be annoying with a DSLR so I sold off all my Canon gear on POTN and got an Olympus E-PL5 with just the kit lens and a 20mm f/1.7. It's been a pretty good setup, and for walking around Italy it was pretty nice for my needs for traveling. I liked the versatility of the size, articulating screen and tap to shoot. However, I missed things from my DSLR like a viewfinder and an overall larger body for my hands to hold onto. At the time I didn't consider the OMD E-M5 because I thought it was too close to the price of a DSLR to justify the size difference. This year I went to Peru with only a rented 14-150mm Olympus lens. Although I liked the near p&s experience (small, all-in-one zoom, tap to shoot, tilting screen, etc), I also missed some features that make shooting a picture more deliberate (size/weight/sturdiness, viewfinder, ergonomics, etc). That being said I'm *thinking* about changing things around. By no means am I "gear obsessed," I just have a hard time figuring out what's best to compromise on. That being said here are my gripes/desires: 1. A slightly bigger/more ergonomic body while still somehow not being too bulky. 2. A viewfinder of sorts (EVF or OVF) 3. Better IQ if possible; my e-pl5 is comparable to my t2i but only under the best conditions... I notice it the tonal/dynamic range isn't as good as my dslr did in some conditions. 4. Pop up flash if possible; mainly for backlit/fill scenarios while traveling. I don't use flash enough to warrant an external flash and the little add-on flash on the e-pl5 isn't bad but it's just on other thing to pack/get lost. I'm not big on having multiple cameras so all options would likely replace the e-pl5 all together. Here's what I have considered: 1. OMD E-M10 - stay in the m4/3 world. Even has pop up flash; still a little small though 2. OMD E-M5 - same as above minus pop up flash 3. OMD E-M1 - same as above; but cost is pushing it for the form factor, etc 4. Canon 6D + 24-105mm kit - larger than other options but for the IQ and versatility I think I could accept the size increase again.The camera is in a diff bracket so cost not comparable 5. Sony A7 + 24-80mm kit - Same price as 6D but smaller; but also limited and expensive lens selection ($1k for a 50mm 1.8 is nuts) 6. Canon Rebel like a t5i or t4i FWIW, I've used the E-M5 and a T2i before so on the OMD and Rebel lines, they're close enough for me to consider having some experience with them. I've also used 40 and 50D's before so I'm familiar with Canon bodies though I've never used a FF canon. The only one I have zero relatable experience with is the Sony. As of now I'm leaning more towards one of the OMD's or a 6D. With all that said, I'm not looking for "the answer" on which route to take, but more like specific perspectives that I can use to aid my decision.
