I had a Pentax camera with a mirror and I liked it, but it was very heavy. The mirrorless Olympus camera I bought takes pictures I think are just as good, and I don't have all that weight around my neck. I'm not a photography geek, though, so you'd have to get other opinions re: photo quality.
And can tell why they have a preference in function and/or image quality.
might very much like to switch to a digital camera that is very familiar to the type they've used (and there are a few reasons high-end photographers may want to stay with mirrored).
So many people want to shoot video these days and for that you want a good mirrorless.

Early designs were TLR or rangefinder cameras, both of which did not look through the lens used to expose the film. This created a number of problems which were fixed with the advent of SLR, which employs a mirror and prism designed to allow the photographer to look through the lens used to create the image. The disadvantage to SLR was it required an increased distance between the back of the lens and the media to allow for the mirror. This means all things being equal, the lens has to be larger and heavier for the same image ratio.
Mirrorless cameras do not employ a mirror and instead have a viewfinder that depicts a representation of what the digital sensor sees. There are several advantages the most noticeable being it allows for smaller and lighter lens designs, like the old rangefinder cameras. It is also less mechanical and more quiet(important for some nature photography) because you don't have a mechanical reflex mirror operating inside the camera. Some mirrorless cameras still have a mechanical shutter, so the noise hasn't been completely eliminated, but others have an electronic shutter which allows for completely quiet operation.
Early mirrorless cameras had problems with shutter delay which has pretty much been completely resolved with faster processors. Another disadvantage is you no longer have an optical viewfinder which some photographers are going to want, particularly if they are used to optical viewfinders.
Is mirror-less more accurate on tripod with higher aperature shots?
Most of them depict the image as smaller than it will appear on the media. As far as mirrorless goes in one respect it will be potentially more accurate because it's a digital representation of a digital image, particularly if you are viewing the final image digitally on a monitor.
Most SLR cameras have the capability of mirror lock up, so the differences in shake between the mirror actuating would be eliminated.
or are you fine looking at a digital screen - it's much more like shooting with a video camera - you see what the sensor sees.
Personally I need to see through the lens so I'd only get mirorless as a point n shoot
Several manufacturers made the switch a decade ago and finally Canon and Nikon have followed suit. All new technology is going mirrorless. The DSLR is going the way of 35mm film.
Regardless of brand, mirrorless cameras have a number of technical advantages. They're smaller, allow for a host of technological improvements and are replacing the mirrored SLR in new design and production. I won't go into all the advantages here but if you're interested PM me and I'll go into as much detail as you want.
It's just the next step in cameras. Why invest in buggy whips when there is a new fangled auto-mo-bile taking up space on the streets?
I would never use anything else and I have been a pro since 1990. But, you will get different opinions from everyone.
Is price range going to be a factor?
It has less to do with the camera and almost everything to do with the shooter and the glass on the end of the camera.
I can afford to buy the best Sony made, but I just don't because I don't need to do so.
All modern cameras with a good lens will create fabulous images, if shot correctly.
I taught photography for almost 20 years so if you have any questions, feel free to ask...either here or in pm. I will be glad to help if I can.
Have you thought about getting a camera sling? I bought one several years ago and it made the world of difference.
There are many out there to choose from.
Just a thought.
If you are not shooting action/sports under poor lighting, you will probably be able to get away with mirrorless.
