You wouldn't think a $2000 APS-C lens would need in-camera fixes. http://www.dpreview.com/news/2014/05...ing-in-camera- software-corrections?utm_campaign=internal-link&utm_source=news-list&utm_m edium=text&ref=title_0_1 There is nothing really wrong with this. There are a number of aspects of lens design which require compromises: correct moe of this and you are able to correct less of that. If there aspects of lens performance which can be corrected out of the lens then, BINGO!, that's a whole lot more scope to correct other problems within the lens. I think it's a good idea and we can expect to see it adopted by other manufacturers. Other manufacturers do it already (Sony, Fuji etc), the thing here is that Leica is supposed to be better, and build better lenses. This is not a bad lens though, and I agree with you that it's not a problem. The end result is what's interesting, not what kind of "tricks" Leica employs to get the end result. The lens is getting rave reviews so it's not like it's a lousy lens and they're trying to cover it up. as you say, the end result is what matters. however, correcting aberrations in the camera is not a trick. it's just another place to do it, something that was not possible until now and for certain things, more effective. It makes sure the corrections are done properly thereby making life easier for the lens designer. Yes indeed. Iit's the combo of design and post processing the signal where some of the transfer ("processing") function of the lens has been moved to software (firmware). It's just good engineering. And if the results are great ... (I don't know if they've passed on the recurring savings to the end customer, however). -- "Big data can reduce anything to a single number, but you shouldn’t be fooled by the appearance of exactitude." -Gary Marcus and Ernest Davis, NYT, 2014.04.07 |
