<p>All good comments. Thanks everyone!</p>

<p>I received it from a colleague who was going FX...and I knew it was suspect. Not worth the repair cost probably. Selling it "as is" right now.</p>

<p>Eric, it was just soft, in the middle. And almost like it had an astigmatism... blotchy. only lens I had that was like that./ </p>

<p>good grief. it's a 20% crop....talk about not seeing the forest for the trees. Regardless, even this one is 2X sharper than the Nikon lens. Like I said, pretty sure I had a bad copy...doesn't mean apples to apples... the Sigma is better than the Nikon. of course, not</p>

<p>It has bugged me for over a year. Not so sharp photos coming from my Nikon 17-55 f2.8 DX lens. </p> <p>I had tried Fine Tuning to the nth degree and to no avail... just started to think that it was just me being too picky.</p> <p>So...I went ahead and bought a Sigma 17-50 f2.8 and today shot a family in the park. Om my God! What an improvement. Sharp as a tack and incredibly rich with good bokeh. Now I see what I was missing and should never have put up with this for so long.</p> <p><img src="/bboard//i66.tinypic.com/sg4hl1.jpg" alt="" /></p>

<p>I have a new lens and just wanted to get your take on the importance (or unimportance) of adding a filter.</p> <p>Pros and cons?<br> Thanks</p>

<p>All great suggestions. I'll try some of these. Appreciate it!</p>

I would like your insight and help/</p> <p>Lens in question: Nikon DX 17-55 f2.8<br /> Camera bodies tried on: Two D300s and two D7100... sample bad results.<br /> Tried AF fine tune in each (-20 all the way up to +20), no consistent better sharpness.</p> <p>Only thing I have not tried is adding a filter.</p> <p>Here is a typical photo. F2.8 in this case...<img src="http://tinypic.com/r/ribv3o/9" alt="" /></p> <p> </p>

<p>I have the DX's Nikon 17-50 f2.8 and Sigma 50-150 f2.8 and that will handle 95% of what I need (sports, outdoor portraits and events)</p>

<p>I 100% agree with Dieter!</p>

<p>White balance set to flash by error??? easy to do that rotating dials, etc. take a look</p>

<p>No Bob H., not one of those. Back in the 80's, Pentax 35mm. </p>

<p>Yes, she was tickled. I told her to just play with her son and let the two of them just have fun and that I would work around that. She said she was very happy with all of the photos. :)</p>

<p>Photographed a woman and her son in the park on Sunday and I really like the upgrade in pixel count and IQ that I am getting with my new D7100 vs my older D300. <br /> So GLAD I took the advice of many on here and took the plunge. :)<br /><br /></p><div></div>

<p>I bought a new D7100 to replace one of my D300's that shutter failed on me... love the D7100... just a bit small for my liking but I guess I will get used to it...even with the battery grip I bought.</p>
