Pretentious Latin twaddle and lens distortion Re: Is Full frame still the most versatile?

plevyadophy - what do you mean by distortion at 12mm on m43?

It's not distortion at 12mm on mFT per se, rather it's 12mm distortion (no matter what format). At that extreme focal length barrel distortion is common (mFT hides it by automatically doing distortion correction, at the risk of some image quality loss in the corners, on JPEG output). To get rid of it optically, means a more expensive and complex lens.

This is wrong. You can deduce that this is wrong through the use of reductio ad absurdem. If it were the case, then compacts and phones with tiny lenses would have insane distortion. They don't.

Dear oh dear, what's with all that pretentious Latin nonsense?

I suggest you go take a look at review sites like this one, SLR Gear, Lenstip, Photozone, Diglloyd and others. I think you will find that it is the wider angle lenses that have the most barrel distortion and the wider the lens the more distortion. And the manufacturer has three choices: leave the distortion uncorrected, attempt to correct it optically, or attempt to correct it by software; in fact one could add a fourth option which is to correct it as best as one can optically, allowing for things such as cost and then to attempt to complete the correction by way of software correction.

The microFT system does the bulk of it's lens correction in software for most of the lenses in the system. Get yourself a raw file from any microFT camera and have a look at it in a software package that doesn't auto-correct distortion. Or if you are lazy, or haven't got the time because you are studying Latin, go over to the Photozone site because the reviewer there often shows the difference between the corrected and non-corrected raw files.

When you have perused all the evidence, please do enlighten me as to what it all means in Latin.
