Pixel Pooper

That depends on what you consider fast, small, and sharp. Which lenses would you say meet all three requirements?

If it were that easy we would have those lenses already. Unfortunately you have to compromise on at least one of those attributes.

That doesn't sound right. With a pupil magnification of 1 (pupils are the same size) you should lose 2 stops of exposure from infinity to 1:1 magnification. With pupil magnification below 1 you ...

The pupil magnification the diameter of the exit pupil divided by the diameter of the entrance pupil. This different for different lens designs, so you have to measure the diameter of the pupils. ...

The A6600 uses the new Z series battery. It also has the most state of the art AF system of any mirrorless camera except the A9, and IQ as good as any APS-C camera. Sorry, not buying it. The OP and ...

Are landscape photographers asking for small slow lenses though? The thing with faster lenses is you can always stop down to f/8 or f/11, but it doesn't go the other way with slow lenses.

If people really wanted small slow lenses, Olympus might not be in so much trouble right now. Unfortunately I don't think that is the case. People don't by FF to use slow lenses. Good luck trying...

Diffraction has nothing to do with the sensor. It is purely an optical phenomenon.

I'm pretty happy with Sony APS-C. I don't need a new body every five minutes, and E mount already has the best lens range of any APS-C mirrorless system.

That makes the maths more complicated, but the answer is the same. The pupil magnification changes the effective aperture, which affects both DOF and diffraction, so the link between them is not ...

Agreed. Thonk you!

You can't always get more light into the sensor. If you can't increase exposure without comprising on DOF or motion blur, there is no harm in raising ISO and with most cameras you will get a ...

The COC should be scaled with the crop, so for this example the crop should use a COC 1/2 the size of the higher mag shot. No worries!

The calculator is giving you the wrong answer because you didn't change the sensor size in the second example to simulate the crop, so this is showing you what you will get if you reduce your ...

There was a discussion on this with image samples here: dpreview.com/forums/thread/4261275 This is one of my posts in that thread: When you increase subject distance you get deeper DOF, but ...

Unfortunately, no, there are no free lunches when it comes to DOF. Equivalance tells us that at the same DOF you get the same diffraction blur regardless of crop or format size. Macro is not ...

The dynamic range of the sensor the range from clipping to the noise floor, but an image also has a dynamic range, as does a display, or a print. The DR of an image is the range from the highest ...

In A mode the camera will reduce the exposure time to compensate for the higher ISO, so you shouldn't get any clipping.

Of course, and for most cameras, the higher the ISO, the less light it will take before clipping.

It depends on the camera. Some cameras just record the ISO as metadata and won't clip the raw file, but as far as I know that only applies to a few Sigma and medium format cameras. Most cameras ...
