An aircraft is a vehicle with a motor and it meets the first definition of "motor vehicle" that you'll find in most dictionaries. If you want to go by a specific localized legal definition, then...

I know the from personal experience that the A7R exhibits the roughly the same behavior as DXO reported with the lenses I adapted to it.  I've never tried an adapter with my e-m1 so haven't been ...

The only problem with this is that digital sensors are not actually able to capitalize on all the extra light from ultra fast lenses. http://www.dxomark.com/Reviews/F-stop-blues

Without a doubt the benefits of shooting RAW outweigh the benefit of the in-camera focus stacking even if just for the additional dynamic range.  You can still do focus bracketing and then do the ...

My first thought when it was announced was that it might be useful for landscape work where you don't need as many frames, but the output is JPEG only so that severely limits the usability for ...

Indeed, although if you look at the original photo at full resolution it looks like garbage, especially all the long exposure noise artifacts near the bottom.  I think this mostly shows that ...

That 9th picture, the portrait of the guy in the forest, has some fairly nasty bokeh.

Flash duration is generally significantly shorter than the sync speed, although that is dependent on the power output chosen as full power shots will usually be on the order of the sync speed. ...

It only affects spot metering.  Evaluative metering is linked to the active AF point by default, but it isn't weighted as heavily as spot metering.

Can you get around it by generating a custom profile for the lens?

Placed 39^th in the challenge. A cyclist suffers as he leads the chase to catch the lone race leader during the 2015 Nittany Stage Race.

All three of my Olympus Pro lenses have a fairly gritty feel to the focus rings so I don't think this is abnormal.

I'd be very wary of their results.  The truth is that almost nothing is known about their methodology.  They give some very vague descriptions but nothing really concrete about either their ...

The front element measures ~26.5mm which is pretty much exactly what you'd expect based on the aperture ratio (25mm/0.96 = 26.3mm).

This is with the Tough E-mount.  As the poster above me noted, assuming the camera can't move at all isn't necessarily true as the shutter could cause the tripod to vibrate slightly.

It's quite possible that the 150-600 has enough mass to mitigate the effect of the shutter vibration.  On smaller telephoto lenses, however, it's definitely an issue but the effect is more like ...

You're really not correct here, for macro shooting where you're pretty much always diffraction limited smaller formats have no advantage in DOF.
