Wow! you guys are bringing a whole new argument to the discussion. This is an angle I hadn't thought of.
I would like to hear more about Larger sensors needing faster f-stops to produce sharp images.
show me what you got!

Not larger sensors, just higher density sensors, and faster shutters, not larger apertures..

Yes yes yes. There is always give and take. It's not too bad in good light where you can up the shutter speed and keep the ISOs low. Low light is a killer. I shoot live music and with the d80 and a 50mm f/1.4 shot at f/1.4 to f/2.8 for the ISOs I almost want , lol, I keep my shutter speed most of the time at 1/160 or higher. I sometimes can go lower but the situations have to allow me . And with the new Nikkor 70-200 e fl with VR on its 160-250 at f/2.8. Not really liking this lens in even marginal dusk darkness. It hunts and also just plain misses. Where my old 80-200 ads-d hot. That's another story.

where did you hear something like that?

From 02Ra and you. see earlier replies

I believe i said:
"Not larger sensors, just higher density sensors, and faster shutters, not larger apertures.."
"Now with the D810/36mpx, i'm not even sure 1/500 is fast enough."

And i think o2ra said:
"But with higher mp you'll have to shoot at higher shutter speeds to stop the blurring effects you get from that high mega pixel sensor. It even happens with the d810."

No mention of sensor dimensions or aperture.

Quote from Canon and an example case on pixels:

"If you have moved from the EOS-1D to the EOS-1D Mark II, you might find that the images look less sharp. There are two reasons for this. First, images captured with the EOS-1D Mark II have less noise than images from the earlier model.

This provides a smoother gradation, which can give the impression of reduced sharpness. Also, the EOS-1D does not have a phase plate. This makes the images look sharper, but can increase the level of false colours. If you want images from the EOS-1D and EOS-1D Mark II to be similar, set the sharpness parameter on the EOS-1D Mark II to ‘1’.

Even after making these changes, images from more recent EOS professional digital cameras can still look softer than those from earlier models. This is because recent models have more pixels, which means that pixel size is smaller (11.5µm on the EOS-1D; 7.2µm on the EOS-1Ds Mark II). Smaller pixels are more sensitive to camera shake, as a smaller movement will cause the image to move across more pixels. You need to hold the camera steadier - ideally on a tripod.

For the same reason, sports photographers also need to re-think their shutter speeds, as blur from subject movement will be more apparent on cameras with more pixels. Where possible, consider increasing the shutter speed, even if this requires an increase in ISO speed".

Yes and one of the reasons say (Nikon) because I know their products , uses 16-21 mp on their sports and action type cameras. And also it allows for more fps and larger buffer capacities.

for sure that is exactly what it takes in a sports camera...

It's funny how many articles are on the internet that disclaim the notion. I was reading a few very convincing stories today...

The manufacturers will tell you flat out that increased shutter speed is now required for today's higher pixel sensors.

Great article! Thank you for sharing your research.
