What is mFT FoV?

This is the Oly Mk2 14-42mm kit lens at 14mm......

A is default conversion from Oly Viewer 2, much like the in-camera jpeg.

B is Oly Viewer 2 conversion but with manual correction at 0 and set to ignore lens data

C is conversion from FastStone Viewer which obviously is the real shape of the RAW

Quite clearly the Oly Viewer 2 so called zero manual correction with no lens input data is still making some correction to hide the fact that the lens really is very bendy. The FastStone effort is probably straight from DCRaw.

So pick your weapons and get results of any shape or flavour as you like.

I told you it was raining here in Sydney so shot through rainy glass and rain falling constantly. Focussed on those trees/bushes past my fence.

Tried every lens more or less and this was about the bendiest one. Have four kit lenses at 14mm and all are about the same bendiness (Oly 14-150mm & Oly Mk1 & Mk2 14-42 & Pana 14-45)
