Re: Problem with lens?

Can you tell what lens you think you need? Then we can tel what way you should go.

It is true that there are more lenses for the m43 then for the nex range, but most FL up to 210mm are covered at the moment with zoom lenses, the most important FL up to 50mm are covered with primes. Some high quality primes from Zeiss are on its way so if you are willing to pay their price that is an option too.

I'm not saying Nex has all covered as some lenses are still needed (short tele prime, high quality zoom lenses etc) But the question is do you need those lenses?

Then the quality of the lenses. Remember that on a M43 camera all lenses are corrected in camera, most test are using correctedd output to test the IQ, on the Nex they most use uncorrected output.

And this is why I sometimes enter a discussion on another forum. To counter these kind of faulty information. Olympus does not correct in camera AFAIK, panny does. That is why some Panny lenses show some CA for instance on Oly camera's where they do not on Panny camera's.

For purists: virtually all Oly lenses are just made that way in the hardware (construction).

2nd point: this corrections are miinors and do not make some sort of bad lens seem better. These lenses are very good and teh corrections are minor.

3rd point: don't use camera raw or silkypix becasue these programa automatically correct too.

4th point: an "informed opinion" of dpreview on this is that this is the way to go. Dpreview on this:

"So is it cheating?

With all this software correction of lens aberrations going on, it's perhaps inevitable that some people will look upon Panasonic's approach as 'cheating'. After all, the argument runs, film camera lenses were always properly corrected optically, so surely the use of software to achieve the same effect is simply cost-cutting, and therefore somehow 'cheating'.

We think this is fundamentally the wrong way to look at it. In photography, what ultimately counts is the final image - the means to get there is relatively unimportant. As we've shown, Panasonic's software correction results in pictures which are technically superior to those obtained using more conventional, purely optical correction methods. This is no doubt helped by the fact that none of the software manipulations used are particularly extreme (aside perhaps from those for distortion at wideangle) - we'd be much more worried if software was being used as a crutch to support the use of significantly sub-par optics. It's also worth appreciating that this new approach is only possible because of the opportunities offered by a system that has no optical viewfinder, and therefore no requirement for the lens to be corrected for SLR-type viewing.

So our considered opinion is that no, it's not cheating, and indeed this kind of processing is clearly the future. All of the major manufacturers are attempting to address lens flaws in software in one way or another, and one advantage of mirrorless system with purely electronic viewing is greater flexibility in what is possible. So the best approach for the photographer is to accept what technology can offer, and enjoy the images it can produce."

Now, this is an opinion. You don't have to agree but I wonder how many people shoot pics without using software to correct it in this segment...Most people purism onluy goes so far...
