    Shooting JPEG-fine, Large on a D50

    This is what I get. No resize just so ppl here can tell me what I'm doing wrong. Are they supposed to be sharper or is this how it usually is? It's not sharp when I look at it in its original size.

    No PP, composition etc. just randomly shooting outside to test sharpness of lens.

    edit: looks like imageshack resized it argh.

    my question is, are pictures supposed to be a bit blurry at their biggest size?

    Try shooting more close up.

    This was shot with a Nikon 17-55 DX f/2.8 on a D200

    But what did it look like when it was at its biggest (if you shot large that is)

    like my originals were about 3000x2000. Looked a bit blurry. When resized to the size of posted ones, looks sharper (of course)

    you will get sharper images shooting in small to medium format.

    wat?


    You'll get sharper images by shooting in a more compressed format?

    what the fuck are you talking about?

    Sharper = more detail

    compression = less detail

    A medium format will always be able to make a sharper print at any given size compared to a 35mm or DSLR.

    Assuming you actually scanned the neg in properly.

    I guess maybe hand holding was causing the blurriness...But there was a lot of light...

    I'll try on a tripod tomorrow. Just to make sure my lens is sharp. Will post more pics tomorrow, including possibly crops.

    even the kit lens looks sharp at f/8 :mamoru:

    open it up to 2.8 and test again

    No shit. Larger negative = more detail.

    This still does not explain your first post:

    Sharper images than what? Isn't he already shooting in 'small' format? Why would you recommend he shoot in med. format when he's clearly asking about the sharpness of his particular lens on his camera?


    Oh, and 1st generation digital shot > 2nd gen. scanned in med. format negative. Even a drum scan cannot accurately reproduce 100% of the detail on the neg.

    not quite sure what more you were expecting but not even the best lenses are sharp at any settings with any lighting. you need to venture out to more than just your front yard to test a lens.

    I see a lot of compression and no clear point of focus.


    Shoot something at a higher quality setting and shoot something with a clear focus point.

    Then post that.

    If you read on some of the boards, the 17-50's had "sharpness" or grain issues.... You could send them back to the factory (for free) or just test it out on your camera before buying..

    I guess only a certain serial# range was affected...

    That looks like a blurry unit.

    watch where you are focusing, you also dont need to shoot @ f22.

    i was wondering about that.

    can anyone comment on the distortion? I think it happens at 17mm.

    this is the Tamron 17-50 2.8 XR Di II LD lens we're talking about right ???

    You're not supposed to be getting ANY distortion on that lens.... I have one... and its sharp as a tack...
