EF 70-300 f/4.5-5.6 DO IS USM

C-RAW processed in DPP4. Taken last night when there was a pause in the rain. @200mm and f/11 this is the sharpest end of the lens. Landscape picture profile w/+2 Contrast used

SOOC JPEG; normal (not fine). Standard Picture Profile w/+2 Contrast. In-camera DLO

SOOC JPEG; normal (not fine). Standard Picture Profile w/+2 Contrast. In-camera DLO. NR-standard used (which does destroy some detail/color). Of note, f/8 does alot for 300mm vs wide open.

SOOC JPEG; normal (not fine). Standard Picture Profile w/+2 Contrast. In-camera DLO. NR-standard used (which does destroy some detail/color). Wide open at 300mm.

Here's a best case (200mm @ f/11), normal case (70mm wide open with less than ideal light) and worst case (300mm wide open, macro in the dark) samples.

Note, even at ISO12800, stopping down to f/8 produced better colors, not just sharpness. This is a lens that performs best stopped down a bit, particularly at 300mm.

Also note, even very basic in-camera +2 contrast does the trick for bringing contrast back into the images. As long as you're exposing correctly IE within 2 stops of correct exposure, basic in-camera post does the trick here with making this lens shine.

2nd note, this is a 2nd hand-lens which does have noteable (but not substantial) dust in it. I don't note any impact on IQ, however, I don't have a clean optic to compare. I'll be looking into getting a quote to remove the dust. Depending on the price, I may or may not get it removed as often dust doesn't have a real impact. In this case though, contrast, which this lens lacks, it's not small potatoes as dust can reduce your contrast. Most (probably almost every) used copies of this lens are going to have dust in it due to age and use. I did however get it at a very ($300) reasonable price. Even if I get the dust removed, contrast will still need to be bumped. I'm curious though how much impact that dust is, or isn't having, and how much it costs to get it serviced as I suspect most folks interested in this gem are going 2nd-hand which this will be a common issue.

As weather permits I'll update the thread. I've gotten some very good samples off the lens as far as IQ goes, but, I'd prefer to wait for more interesting subjects/framing to post IE I'll add more interesting samples as I capture them. Weather should permit this weekend. We'll see.
