Who uses FD lenses on a digital camera?

<p>FD/FDn lenses are all I use on digital cameras and I've come to realize that and learned about "sharpening". But have seen nothing that suggests its an FD/FDn lens issue...apparently its an inherent characteristic of digital technology.<br />A "sharpening feature"seems to be imbedded in most digital post processing software packages.</p>

<p>An example of Before and After sharpening.<br /> Made a distant full length shot of a Red Shouldered Hawk on a limb with an FDn 300/4.0-L without a tripod.<br />Then when cropped way up for a head portrait I saw DoF was too shallow and also thought it was a bit soft.<br />Bumped it with a couple clicks of 'sharpening' for some improvement, made it worth keeping to me.<br /> <br /> <em><strong>BEFORE SHARPENING</strong></em></p>

<p>Its a feature built into most "post processing software packages"...you display a photo you might want to see if it could be sharpened up a bit, and usually just click and slide a slider button on the screen while watching the photograph and you'll see the image sharpen up (or not)...and you can adjust how much, etc...just takes a few seconds. Here's a Before and After of your beautiful ocean / sky scene:</p>

<p>LOL...reminds me of the old saying about opinions being like noses...I suppose there are times when soft, even blurry photos have their purpose and appeal to some...but not to others.<br /><br />This example & discussion was specifically about "sharpening"... how to do it, etc...a positive attitude in a positive attempt to help a fellow photographer with a technical question...because bottom line there's no question the industry recognizes the inherent characteristic of digital images in general is that they can / usually do benefit from some degree of sharpening.</p>

<strong>No sweat...just trying to help regarding your opening question which implied you may have been bothered by soft images.</strong><em><strong><br /></strong></em></p>

<p>I use mine on an EOS-M with an oddball adapter I got for less than $15 from DealExtreme. The two mounts are off by about 120 degrees so it's a bit inconvenient to set the aperture (and essentially impossible to use my 500mm mirror's tripod mount), but it works and the whole setup was probably cheaper than most new lenses.<br>

I haven't really noticed a lack of sharpness, but I haven't really been printing anything from it yet. And I haven't been staring at pixels.</p>

<p>The issues which I have seen, using FD lenses on a Sony Nex 5 and a Fujifilm X-Pro 1, are that it is often necessary to stop down, say to about f2.8 or f4, to get acceptable sharpness and that with very fast lenses the amount of light overwhelms the adaptor (I use Novoflex, so it is not a quality issue), so that a lot of additional stray light gets into the picture. </p>

<p>Hard to express, but it's as if there's too much stray light. You can see a bit of the effect in the image below - which is not strictly comparable, as this was taken with a Bower adaptor on an EOS 1Ds III, but it was shot at f1.2 on the FD 85mm f1.2L, so you get perhaps something of the idea. (I'm 6,000 miles from home at the moment, so this is the best I can do ... ).</p>
