Lens Correction by Panasonic.


There have been lots of recent posts on various forums, about the use of in camera and software correction of distortion & CA, by Panasonic in their G series Micro Four Thirds cameras.
The majority of the posts have been critical of this. The basic argument being that Panasonic are in some way "cheating" or selling sub-standard lenses & then fixing their imperfections later.
I paticularly enjoyed this one:-

where the creator of the thread was truly getting his boxers in a twist about the shortcomings of the 14-140mm zoom, with regard to CA. (Chromatic aberration - see:- http://en.wikipedia.org/wiki/Chromatic_aberration) and fringing ( http://en.wikipedia.org/wiki/Purple_fringing)

My reaction to this was to go out & order the 3 Lumix lenses that I don't currently own. Because when I read through all the threads I thought what a great solution this is. It saves me doing it.
A few years ago I had a Canon 5D and a 16-35 F/2.8 L series zoom. This combination must have set records for the amount of CA & purple fringing it generated. It was horrendous & took ages to fix. The image in this post is an average example - I had worse than this. This from a very expensive lens.
I've had equally bad results from other zoom lenses by Nikon, Sigma, Tamron etc. Its one of the reasons I stopped using zooms, as the amount of post-production work involved was becoming overwhelming. After reading these posts I went back and looked at some recent images I took with my 14-140 zoom on my GH1. They were refreshingly "clean" & while not entirely "fringe free" were substantially better than the example shown.
Panasonic are not alone in doing this, other manufacturers are introducing it. To my mind its to be applauded.

I've been trying to sort out a super-wide option for my m4/3 system for some time & have finally gone with the Panasonic 7-14mm. Purely because of the in-camera & software "fixes". The point of taking photographs is the photographs. Anything that gets me from pressing the shutter button to edited image in the shortest possible time is alright by me.
Well done Panasonic.
