But what about the focal plane shutters? Should I be shooting landscapes in Silent mode (ie, Live View>Silent Shoot>Mode 1 for my 5D Mark II) to reduce curtain vibration by half? Why haven't I heard anybody doing this?

Unless you're doing semi-long exposures, or using slowish shutter speeds, the 'slap' of the mirror has a negligible effect on the sharpness. And the wider the focal length, the less it matters. Kinda like diffraction: only important to pixel-peepers. 'The success of the second-rate is deplorable in itself; but it is more deplorable in that it very often obscures the genuine masterpiece.

(3 edits in all) | Mar 28, 2017 18:00 | #3 All the moving stuff adds to blur but there are times it's minimal. The faster the shutter, the less the impact. MLU reduces it more. A wide lens makes it less noticeable as well, but it's still there. The below pic is a 100% crop of a long exposure image I took of the ISS at 17mm. Granted that this is a long exposure but you can clearly see how big the impact is in the first few MS. This was due to me forgetting to put the camera in MLU so most is from mirror slap,  Not sure why, but call me JJ.

I'm not talking about the mirror. I'm talking about the curtain. The mirror does not move while the sensor is exposing, but the curtains do. I would think the curtains can cause more vibration than the mirror. And because Silent mode (Live View>Silent Shoot>Mode 1) is suppose to use fewer curtain movements, I surmised that this mode can help reduce vibration. On the other hand, I suppose I would've heard about it by now if it really did make a difference.

However, this is in microscopy so even blowing on the camera is going to show results. I'm thinking that under landscape conditions, it will be much less noticeable.If at all...

I don't know, the rest of the article also shows a clear impact albeit at 400mm. Scroll down a bit farther. Not sure why, but call me JJ.

He proved that Live View>Silent Shoot>Mode 2 yields consistently sharper images than with Mirror Lockup alone. So ya'll been settling for less and not knowing it. Like me until now. FWIW, I attended a Canon presentation a few years ago, and the presenter indicated that Silent Mode 1 gave the sharpest images with Silent Mode 2 being the quietest. I suppose it's easy enough to test what works best for you.

Indeed; and some of us prefer to look through the viewfinder when making pictures.  100% crop with C1P sharpening:  100% crop with no software sharpening:  Can you see any difference in the actual picture? As in, any difference that matters to someone who ain't gonna zoom in to 100% or beyond? I can't. And I'm willing to bet to-day's martini that my viewers (non-photographers) can't either, or would care if they saw any. I can understand the quest for image excellence. But, like many other things, we can develop an obsession with every little thing.
