Put off your purchase for awhile. Sony is rumored to release a new APS-C camera soon. It is expected to be a baby A9 and if true will blow away all competitors in that class.

Cdouthitt gave you the list. Since you liked the Olympus 4/3rds except for focus speed, I think you would be satisfied with the speed of focus of the Olympus E-M1 mrII. Much better than the E-M5 mrII. If the Olympus system doesn't appeal to you anymore, the Panasonic and the Fuji X-T2 and X-T3 would receive my nod.

Stay with Nikon Mirrorless. You have glass invested!

Bwhahaha. If he couldn’t afford the a7 series Sony, then how’s he supposed to afford the Nikon. Besides, Nikon has some major bugs to iron out first. Like it’s focusing system.

I have the Sony a6500, the 18-105 and 35 mm lenses. Love the outfit, light and a lot easier to carry. I also have and like the Sony rx100v. Great small camera to carry around.

I have Olympus OMD-EM1 Mk 2 and nikon D500 The nikon leaves it for dead for birds in flight but for anything else the olympus is excellent. The electronic viewfinder is too slow to pick up the target. You can set it to multi target focus and set it to track and it is ok but not a patch on the nikon. I saw someone with an attachment on his hot shoe called olympus red dot which was a scope type of thing and you looked through it and he could pick up the target much faster, worth looking at.I have olympus glass so changing to sony (big learning curve ) or fuji would mean buying new glass.

I have an Olympus EM 1 Mark ll and it is a fantastic camera, focus is lightning fast and I use it for bird and wildlife photos on a daily basis. I really like the EVF and I have the preview delay set to zero so I can track and shoot in CAF without loosing site of my target.

I have the very same issues with my cherished D500 and its lenses—they get heavier and bulkier.as I get older. One of its greatest assets though is its seemingly endless and limitless buffer, especially when I shoot ice hockey and other action shots.

I’ve tried several mirrorless, but haven’t found as good a buffer. Maybe the Sony A9 but the lenses are pretty heavy.

I’ve tried the Lumix G9. Not as small or as light as I’d like but not bad. I used a Lumix 35-100mm f/2.8 lens and got excellent results for fast sports photography. With its MFT sensor with a 2x crop factor, I had the equivalent of my heavy Tamron 70-200 that I use with my D500. Buffer not bad but not as good as the D500.

A step down from the G9 is The Lumix G85 which is smaller and also very good. With the 35-100 f/2.8 lense it’s pretty light and compact. Buffer not bad.

In comparison to the complicated and encyclopedic Sony menu system, the Lumix menu is a breeze.

I think the answer to the weight and bulk issue is not only mirrorless but micro four third sensor as well—which will give you a much smaller body.That way you will get the benefit of the smaller, lighter and more compact lenses too. BTW Lumix and Olympus lenses are interchangeable and both have image stabilization.

I too am currently looking to switch from my canon aps-c kit to mirrorless. My reseach is leading to the E-M1. My question is is the mark 1 up to the task of mostly family and some light wildlife. Mostly birds on feeders. BIF is a bit beyond me at this point. The mark 2 is the dream bug budget may dictate the mark 1 with some better lenses.

Since weight seems to be your primary issue, calculate the actual weight of the kit you use now and then calculate the weight of the proposed kits (including equivalent lenses) Make sure you are actually saving weight. This varies for each manufacturer and model. Some mirrorless kits weight nearly the same as their DSLR equivalents. Some are actually lighter.

Cdouthitt is the member I would ask though. I think he has been in the mirrorless world longer than most.

What are you using for a lens on your Olympus? I have the same camera and I’ve had no slow focus problems with my 14-150 II, my 25mm, 35mm, or 75-300. Just did a workshop on action photography with Olympus and the camera was up to the task.

C-af isn't usable on the original EM-1...can't trust it. That was one of the reasons I upgraded, along with the higher mpx, high rez shot, better IBIS, and improved highlight/shadow recovery.
Keep an eye out on the buy/sell forum at http://www.mu-43.com as well as the olympus outlet store https://www.getolympus.com/us/en/outlet for used em1ii bodies.

I switched from Nikon to Fuji XT2 with the 18-55 "kit" lens and I am really enjoying this camera. I've had it about a year and it has made taking pictures "fun" again. ( I have added 4 other lens during this time frame - all are great )
