Im leaning more and more toward the idea of a miniature mountain just across the meadow.

Quite clearly, he agrees with ME.
Just like *EVERYONE* else does.

DO Lenses Have MP Ratings?
The issue is a lenses' resolving power when it comes to higher meg sensors. This is strictly resolution not creative aesthetics or characteristic properties of any given lens.

When Nikon first launched the 36mg FF D850 they provided a list of their lenses that could resolve that many pixels and lenses that could not.

When Leica Launched their 37mg Medium Format Digital DSLR (the S system), they said the new S lenses could resolve up to an 100mg sensor. Their current S3 model is 63mg ... that platform is probably being discontinued in favor of mirrorless. I expect an 100mg Leica camera in the future.

Hasselblad and Fuji both have an 100mg sensor mirrorless MF cameras. Hasselblad is redesigning their lenses and Fuji seems to have certain optics that make full use of the sensor's resolution. I've retouched work from both systems and the detail is jaw dropping. If I were a landscape photographer I'd get a Fuji GX100 is a NY heartbeat.

Sony have re-released many lenses that seem able to fully resolve the 61mg sensors as well as provide better AF etc. Sigma has done the same.

Interestingly, I first went for these higher resolving versions but in some cases came to miss the creative aesthetics of lenses like the Zeiss versions. All but a few of my Sony camera lenses are now Ziess.

PIC: Sony A7R-IV, Zeiss 50/1.4 ... trust me this lens resolves like crazy ... I made a giant print of this for a client and you can stand 1' away and see the detail.

Just imagine what an 8x10 digital view camera would provide!

And yes, some people would want one.

Love this shot.

You are right about the need of great resolving lenses to match these high megapixel sensors.

SAB (SonyAlphaBlog) has done MTF-sharpness testing on nearly 200 fullframe E-mount lenses and has its results that show which E-mount lenses can resolve those higher megapixel sensors, Sony and third=party lenses..

Here it is : Which Lenses to maximize the potential of your Sony A7RIV/ A7RV / A1 / A7IV…?

Cheers and best to you.

BTW, Zeiss will not be making any new E-mount lenses ever again. They have moved to making branded smartphone lenses and industrial and medical lenses. Much more profitable for them.

Shoot some 8x10 film and scan it, just to experience the futility of 8x10 digirtal.

That would preclude that I purchase an 8x10 view camera..... and film.
Nope.
I will totally survive with my 4 and 15 MP cameras.

All you need is a box with a pinhole ....

And the sensor.......

You mean that sheet of 8x10 film ?

No, digital sensor.
Just imagine the resolution

Copy and past from Teledyne Princeton Instruments:

"It is important to consider the resolution of the camera lens when determining overall system resolution. The ability for a lens to resolve an object is limited by diffraction. When the light emitted from an object travels through a lens aperture it diffracts, forming a diffraction pattern in the image, this is known as an Airy pattern, and has a central spot surrounded by bright rings with darker regions in-between. The central bright spot is called an Airy disk, of which the angular radius is given by:
θ=1.22λD (Where θ is the angular resolution (radians), λ is the wavelength of light (m), and D is the diameter of the lens (m).

Two different points on an object being imaged produce two different Airy patterns. If the angular separation between the two points is greater than the angular radius of their Airy disk, the two objects can be resolved (Rayleigh’s Criterion). If the angular separation is smaller, however, the two distinct points on the object merge.

The angular radius of the Airy disk is determined by the aperture of the lens; therefore, the diameter of the lens aperture also determines resolution. As the diameter of the lens aperture and the angular radius of the Airy disk have an inverse relationship, the larger the aperture the smaller the angular radius. This means that a larger aperture results in higher lens resolution as the distance between smaller details can remain greater than the angular radius of the Airy disk. This is often why astronomical telescopes have large lens diameters to be able to resolve the finer details in stars."

This is why a poor lens design, or aperture diffraction can produce less resolution than what a sensor is capable of producing.

I currently have a Sony A7R-IV, A7R-V and A7C-R ... all delivering 61 meg maximum.

I still have the org A7R, 36 meg, and a A7-II with 24 meg.

The A7C-R is an attempt to downsize for everyday work without losing much ability from the A7R-V. It is quite small ... almost as small as the original A7R.

To answer the other question about lenses. Yes, as the meg count went up it put pressure on lenses to be able to resolve that level of detail.

But...

what good is your 61 megapixels if you only view your image on a monitor, or post them on social media?

Lotsa' pixels are only adventitious for large printing or a cropping advantage... and nothing else.

Your nice 61 Sony image posted on FB is only 6 megapixels in size after you prepossess it...
