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

Eh what? I have a Sony A7S, A7 II and A7R II; all full frame and interchangeable lens cameras. You just don't have to fine tune lens autofocus on a mirrorless camera!

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!

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?


Yes pure BS as far as IQ goes - IQ depends on sensor size and quality, and lens design mainly, aside from factors under photographer's control. Mirrorless vs DSLR boils down to photographer preference for EVF or OVF mainly. ML has many advantages and DSLR still holds a few but that gap is rapidly closing.

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.


D810 36.3 Mp, D850 45.7 Mp.

If you can’t see the difference and dumbed down to 240-300 dpi for printing, one certainly cannot print the difference, the whole discussion is an exercise in mental masterbation. Censor size is a bigger factor for detailed photos. A medium format camera will kick your ass every time.

Blanket statements like that are generally too small to cover the subject adequately. And if you know what it's like to have a small blanket on a cold night...

As you said, electronics play a huge role in the final result.

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.” 😄

I think you should go to your local camera shop and pick up an Olympus OMD-EM1 Mark ll, and see and feel a pro level 4/3 mirror less camera, weather sealed, moisture sealed and freeze proof and experience 18-60 frames per second, and check the price.

Try comparing a Nikon D850 with a Leica SL.

I don't recall seeing that said but if it has it is a not an accurate statement.

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.

You forgot the most important contributor to image quality which is the person behind the camera.

Actually, of all the criticisms and comparisons between mirrorless and DSLR's I don't think I have come across anybody saying mirrorless can't match DSLR for image quality which would be ridiculous. The comparisons are usually along the lines of no weight advantage when long lenses are taken into account; lack of native long lenses; lag time; slower focus; short battery life; menus versus buttons. Many of these are no longer valid or will soon be a thing of the past.

Check out why these Top Award-Winning Pro shooters switched to Sony Mirrorless cameras from DSLRs just in the past year..

Mirrorless has some critical advantages that NO DSLR can physically ever have, no matter the brand of DSLR. Mirrorless image quality easily equals and often surpasses image quality from DSLRs. I was a top-end Pro Canon DSLR user for 40 years, yes 40 years, and I switched to Sony Mirrorless in January 2017 and would never go back to ANY DSLR ever again.

Look at this Top Pro Shooters Sony gear he is using right now at the Winter Olympics. And click on his Instagram link in this story and see his actual images this week from the Olympics, and then talk about mirrorless image quality. Anyone that tells you that mirrorless takes a back seat to any DSLR anymore, is just a DSLR fanboy.

Even the excellent Nikon D850, arguably the best DSLR out there, was quickly matched and in some ways surpassed when Sony announced its mirrorless A7R3 in late November, and then took more camera-of-the-year awards from the industry.

"i.e.: you don't have to fine tune the focus for each lens you use"

Is this statement true? Or is it the fact that you can't fine tune the focus for each lens you use?

yes it is true, with mirrorless cameras there is no need to fine tune the focus for any lens. The reason is that in mirrorless cameras the focus is actually read at the surface of the image sensor, so the focus you see in the EVF (Electronic Viewfinder) is the actual focus taken at the sensor.

Whereas in a DSLR you are focusing on the image refleected up to the optical viewfinder by a mirror, so any critical misalignment of the mirror and/or lens flange wear can create a difference in the focus distance from the mirror-reflected image and the actual distance from lens to the sensor where the picture is taken.
