Thread: Does the sharpness of lenses still significant??

    Default Does the sharpness of lenses still significant??

    Just curious, does the sharpness of your lenses still an important factor, even with the help of sharpness tools in photo editing softwares (GIMP, PS and etc) ... ?

    If the original image is not sharp, there is only so much you can do in post processing!

    post processing sharpness looks different from lens sharpness. its less noticeable when the print is viewed from a distance though

    Agreed with Deadpoet.

    If it is not important, why would people still willing to pay so much for a better lens?

    Depends on what you are sharpening. If it's just a 640x480 or smaller image I don't think it is that crucial. But when you reach 12mp resolution, any inferior lens will show clearly on the 100% crop of the image which sharpening tools and unsharp mask can only help so much.

    Personally, sharpness is important, and maybe even more so than other things such as contrast and saturation. Sharpness, or the amount of 'pop' in an image is the easiest criteria I use to see if the lens I have is a dud. My eyes aren't good enough for too much else.

    It does look skewed, but your question is indeed something to think about. Sometimes I think that a circular polarizer placed over a cheap lens to deepen colours will add so much appeal that I'd look less at sharpness. Unfortunately for us, most cheap lenses have a rotating front element that makes polarizers a pain to use, otherwise I'd certainly consider that for my kit lens.

    Hi!

    Would like to post a link for your consideration

    http://ck37.image.pbase.com/image/55778014/original.jpg

    The original post

    http://forums.dpreview.com/forums/re...ssage=17060014

    It mentioned that the picture was taken with a very inexpensive 75-300mm canon lens

    Given the wonders that post-possessing can do to a picture.. it is still necessary to invest in an expensive lens..? Of course.. an off-focus shot cannot be compared to a well focus one.. but maybe a shot that is taken with a cheap lens can be "transformed" to one that is no different from that taken with an L lens? In that case, is it really necessary for an expensive lens? (other then the maybe larger max aperture, and better built etc....) if just considering the final possible picture quality after PP.



    Regards

    what u said makes some sense, but wouldn u rather get the quality of the pic the moment you click the shutter than to spend hours sitting in front of a pc and doing major post processing to boost up the pic?

    Using the dpreview example to say sharp lens is no longer important because of the advance of post processing software is completely absurd. Why? The comparison in dpreview is to demnstrate the power of the software. It was not to compare the sharpnes of a lens.

    The example quoted, yes there is definately an improvement after the image was post processed, however, we have no idea if the example, taken with a cheap EF75-300 will be able to stand up to a similar picture taken wth a say EF70-200L.

    Anyway, if the original is not sharp, it can be sharpen in post processing, but each and every action is degrading the original image. I stick with a sharp lens anytime.

    sharp lens anytime! too much sharpening in post processing makes the photo, awful.

    moderate sharpening in PS is fine, so long as the artifacts and such don't show.

    I'm not one of those who likes to spend hours on the PC doing PP. I would rather have a sharp lens anytime. In other words good out of the cam pics (shaprness, saturation, contrast etc). I grew up on film and to me there is no substitute for a sharp lens.

    For most consumer grade lens they are sharp in general, at least
    good enough for a 4R print.

    But for larger print, I think the sharpness of lens is significant.
