It's been said a number of times here on UHH that a mirrorless camera just can't take images equal to those taken with a DSLR. I'm wonder how that is a valid supposition. It seems to me that once the image hits the sensor, the rest is up to the electronics to process that image, and it makes no difference how it got into the camera at that point.

So how is it that having a mirror and pentaprism in a camera makes its images superior to those taken with a mirrorless camera?

Not true at all. A 42 Mp image out of a Sony A7RIII is just as high quality as the 45 Mp image out of a Nikon D810. Mirrorless fanboys will argue that there is less chance of camera shake with that supersonic mirror slapping up in a DSLR, of that Mirrorless cameras are smaller, etc.

It is the Photographer behind the viewfinder that makes the shot.

Not sure you will get a blanket debate between mirrorless and dslr. You WILL get a debate on silent shutter, AF speed, blackouts, EVFs vs OVFs and the pros and cons in various shooting situations with various camera bodies.

...and the comment about hitting the sensor is also up for debate. The sensor type and size impacts tone and noise so the debate does not stop there.

It is ridiculous to say that a mirrorless camera just can't take images equal to those taken with a DSLR. That implies that the mirror flopping up and down in a DSLR and an autofocus sensor separate from the image plane will improve image quality. Image quality depends on the lens and the image sensor. The mirror in the DSLR actually causes vibration that is evident as blur in images at some shutter speeds. The separate AF sensor in DSLRs means the AF path is different from the image sensor path. This results in front or back focus problems if the mirror or AF sensor are not perfectly aligned during manufacturing.

Differences in image quality also depend on the manufacturers implementation of in-camera software and supporting electronics. Given the same image sensor,
one company may chose to sacrifice some image quality at low ISO to achieve improved image quality at high ISO. Another company may make the opposite tradeoff. Or one company may simply implement their support electronics and software better than other companies resulting in superior image quality.

That's hard to believe without supporting evidence.
Seems it would imply that the sensor and/or the processing software are inferior to DSLRs, which I highly doubt.

All this is true, as far as I’m concerned. I do a lot of reading on things, and I’ve found nothing to suggest that a DSLR will take a better picture than a mirror less camera. And I challenge anyone to look at a set of photos and be able to tell which were taken with a DSLR and a mirrorless camera. I have just found it interesting that some will make that statement, and I’ve never found the basis for that. And like it or not, even though the DSLR is the heavy duty workhorse in the industry, mirrorless is slowly (or not so slowly) encroaching on the DSLR kingdom. It’s just a matter of time, in my opinion.

If this has been said, it is hogwash!! I would say a mirrorless camera takes images superior to those with a DLSR, primarily because you'll get better focus with a mirrorless camera, i.e.: you don't have to fine tune the focus for each lens you use. Also, with mirrorless silent shutter and no mirror flopping about there is less chance of vibration causing image blur.

Of course those that think an optic viewfinder is God's gift to man/woman will consider a mirrorless camera to be substandard; however, I'll been there through decades of Canon DSLR camera usage and after using a good electronic viewfinder will never go back to a DSLR and optical viewfinder.

Nothing preventing a photographer from getting superior images off either a DSLR or mirrorless camera except the photographer him/herself!

I agree - and I found a mirrorless camera with a viewfinder that I can actually like after decades of squinting into peepholes.

I think you’re having a brain freeze all the way up in Alaska. That statement of yours or what others have said is flat out wrong.

Yep, that is just a false statement. Of course, mirrorless cameras can produce images equal to DSLR's, many point & shoots can too!

It's not.

But until recently, mirrorless cameras relied on contrast detect focusing, which is a lot slower to acquire focus than phase detect. Sony, Olympus and possibly a few others figured out how to populate their sensors with hybrid focus sensors, which are amazingly fast.

While the image quality of a mirrorless may be equivalent, or slightly better/worse than a DSLR, the kinds of shots you could get have been different.

Well, I guess we’ll have to agree to disagree on that, because it has been said on here that DSLR’s are superior to mirrorless. I’ve just never figured out what the basis for that assumption is. We have DSLR fans who love their cameras and wouldn’t have it any other way, and there are mirrorless fans who favor theirs. What I will say is that I believe the professional level DSLR’s may be superior to the current mirrorless cameras in that they they are certainly more robust. They’re built for heavy duty use, and are priced accordingly. No brain freeze up here. In fact, I think we’ve been having a milder winter here than in a lot of places in the “Lower 48.” 😄

Now there's the hogwash. You're saying mirrorless cameras don't have interchangeable lenses?

Not valid at all. The quality of the picture is dependent on the quality of the lens and the sensor and there is no reasons both DSLR and Mirror-less can not have the same quality lenses and sensor.

Greg, call and talk to everyone of these guys, they can likely explain it better than anybody here will be able to!
While you’re at it, ask them why they use Canons!!!
This IS a year old now, maybe they’ve all switched to mirrorless?!?! LoL
