Not really, just thinking that a heavy vignette & heavy T-stop combined with average weighted metering could render a rather diff shutter speed compared to a lens with a lesser T-stop and lesser vignette.


Don't make a mountain out of a mole hill. Most vignetting occurs at the extreme edges of the frame - where almost no DSLR has any metering sensor cover anymore and the t-stop difference you will only ever notice if you meter externally - most lenses are within 1/3rd stop difference from the actual f-stop...

You can notice it if you shoot two lenses of different complexity side by side - but then again it's just that minute difference of 1/3rd stop...
