This is bringing innuendo and conspiracy theories to farcical levels. You've got no named source, no citation, no link, no spec sheet - just an allegation, so far unsubstantiated. It's worthy of gossip rags.
At launch, the reviewers all had pre-release models to base their initial reports on. Their was, as it turned out, some MISINFORMATION, not lies, nor duplicity nor conspiracy. It wasn't just software correction - there was also doubt about whether or not the T had an AA filter - some were told yes, others no. It was clarified - the answer is no. Likewise for software correction (on M lenses). The T lenses do have software correction.
Software correction is not only for distortion, but also luminance vignetting and colour drift. I imagine it would be a time consuming and laborious job to correct the whole backlog of M lenses for the new aps-c sensor. Certainly difficult in time for the initial release but something they could add at a later date via firmware - if they so wish. Leica seem to be keen to differentiate amongst their products. Sinar - S - M - X and T. Now the M's have built-in correction already, the T is aimed at a different market - why would they ?http://j.mp/1c7dRuR#sthash.aSeDbv8f.dpuf
Farcical? Perhaps, but the fact remains that as of today, there has been no official communication from Leica to clarify whether or not the T lenses have software correction of optical defects. The fact remains that during a presentation/interview a Leica representative said that the T lenses use only optical correction. This is not true.
So yes, Leica have not lied, but a Leica representative was one of the following: ignorant about the product; overenthusiastic; full of BS.
I was not discussing the filter, and I have no problem with software correction, just with false allegations and claims.
Relax, I am sure the T is a great camera, I would buy one with the 35mm equivalent lens if I had the money. As it is, I make do with the also excellent Fuji X100...
