Unfortunately, you did not mention your favoured genre of photography. If you prefer wildlife photography then a high quality, second hand Olympus EM1 mark II would be worth checking out. Don't be fooled my the small M43 format, in many instances it matches APS-C and full frame. In my hands, it is a better wildlife camera than my APS-C Nikon D500. Olympus produce some fabulous, lightweight lenses and there will be some very good second hand ones available. I owned quite a number and they were all superb. If you are not a wildlife photographer, you could take a look at the Olympus EM1, again there should be some cracking second hand models available. The EM1.2 is a feature rich camera, which makes it suitable for general photography too.

I currently own a Sony A7III and A7II, both full frame with the A7III being a superb camera for wildlife and the A7II pretty good. Both are excellent for general photography. Sony produce some terrific lightweight lenses in full frame format. The A7III is still quite expensive and may not be readily available on the second hand market. I am unable to comment on other mirrorless cameras, as the above are the only ones I have owned. You may care to check out a YouTube channel known as Mirrorlessons.

I made the switch to olympus E M-5 II from nikon 7200. Weight and size was the primary reason. I now find I like my pictures much better. Took awhile to u nderstand the differences in light I was seeing through the viewer.

We seem to be, amongst other things, talking weight. MY Panny G3 + Panny 35/100 = 20 ozs. My Panny G5 + Panny 14/45 = 22 ozs. My bag + two cameras and three Panny lenses + speedlight + two spare batteries + two chargers and memory sticks = 5 lbs. Fact! So we are not just talking a few grams difference.
My 16 mpx kit, being M43, is capable of all I could wish for (I don't do Vid) - For me, a G9 would be GAS.

Ford 150 Limited, I loved it but decided to move to a Toyota Tacoma TRD....love it also. Guess its why there are so many options out there for all the different personal preferences people have. Besides, its what money is for, to spend it, even if its on GAS... Cheers PixelStan

Your call. Do what you believe is best for you. You can figure this out. It's not hard.

Bruce, Mirrorless (FF or APS-C) is where the technology is moving.....go to your nearest camera store, if one's available, and do a touchy-feely on various brands, or, if possible, rent a brand for a day, and see what you like about each one. Maybe you have a friend who has a ML camera, get their input. If you have the money, buy whatever you want. Don't like it, sell it and you're only out what would be a couple weeks rental prices....I have been with Sony ML for some years now and have no regrets at all.

I recently bought a Fuji, the x-T 20 and it is quite a nice,capable, and small Beauty. I really like it. For lenses,I got their 100-400 with the 2/X rear extender, also the 55-200 & the 18- 50. That right there leaves almost all of my Pentax & Nikon stuff at home on the library shelves. I doubt that I will ever regret going FUJI. Such quality,the glass. RJM

I have the Olympus OMD e-Mark 5 II that I adore and I’m a former Nikon user who made the switch. To save some cash, check out used or refurbished. This model is weather sealed and it pairs wonderfully with a 14-150 (28-300) weathersealed zoom. Stabilization is in the body which gives you much broader access to lenses. The touch screen takes some getting used to but not bad. The screen saves you from having to dig thru menus when you need to change a setting or access a special feature.

. The price on the Olympus E M-5 II has dropped through the floor with the schedules release of the Mark III

I am currently in the process of doing exactly what the OP describes. Selling my Canon 60D and all my Sigma EX lenses. I have decided on the Olympus OM-D E-M1 II with the 12-100 f4 M.Zuikio and tbe PannaLeica 100-400 along with the Summilux 25 f1.4. It wwill represent a huge step up in capability as far as the body goes and a significant increase in reach. It will also be several pounds lighter and much smaller. I have done months of research, narroewd it down to the e-m1 ii and G9. Then I went and handled them in a camera store. The e-m1 is slightly smaller, lighter and fit my hand better. (Mostly I liked the control layout better). Then I rented the e-m1ii with the 12-100 lens for a week. I don't pixel peep, don't do much low light stuff so the m43 sensor is perfect for me. Quite frankly the image quality from this combo is stellar... Way better than my aps-c canon, and I had some stellar lenses for it.

Mirrorless cameras have been around long enough that timing isn't a concern. Of course, you can always wait until the next great camera is introduced, but then you would always be waiting.

Yes, the Fuji X series has a great reputation. Try some comparison sites to compare features. Then look for reviews and comparisons. Whatever you buy, it won't be junk.

Read comparisons and specs, and decide what features are important to you.

I own multiple Canon, 3rd party lenses, and also 70D, 60D. I just bought the Canon M50, and it is an awesome little camera. Reminds me of a shrunk down 80D. Also with, an adapter you can use all of your lenses. Much lighter and will be used as my travel camera. Great IQ, and Video in 1080P, I am not using 4K.

If your not looking to spend a lot of money and still want a good mirroless, try the Sony A6000. Got a really good deal at Best Buy. I have it and really like it. Light, nice lenses and produces good quality images. I had lots of Canon equipment and really liked the idea of a really good mirrorless so I sold all the Canon stuff and bought the Olympus E-M1 MK II and just love the camera and all the lenses. I did go with the f2.8 pro lenses, not cheap, but hay at my age this may be the last camera I buy so I went for it.

This is just one opinion.

Knowing your camera means knowing it's menus. "Dig thru" sounds as if you don't? However, Panny menus are well documented as being easier to use than Olympus. In all things photographic, beware GAS. The OMD e-Mk5-11 is, I agree, a great camera.
