Replying to Sharpness Issues: Canon 60d + L Lenses + Lightroom

Hey guys,

So I've been getting really pissed off lately because my photos just aren't coming out as sharp as the used too. I shoot with a Canon 60d, 17-40 F4L, 50 F1.8, and a 70-200 F4L, thats pretty good glass. I know my 17-40 has to be shot F8-F11 for best results, same with my 70-200. 50mm is just a piece of shit, don't ever buy it, the amount of light fall off is just stupid wide open. I try to stay between ISO 200-800, but I shoot a lot at night and don't always have my flashes with me so sometimes I have to push it up to ISO 2000+. I'm pretty OCD about keeping my lenses clean, and I have good filters on all of them.

I have a feeling thats its something in my workflow, as apposed to on camera thats causing this issue. I'm shooting RAW, the super-flat colour profile that Will Start uses (posted it on here a while ago), importing to Lightroom, editing, and then exporting as Jpegs for web use. I'm fairly competent in Lightroom, and I know that over editing causes a decrease in sharpness and increase in noise, so I try to stay away from playing with the exposure too much.

Few other things that have crossed my mind. Lens Calibration issues (don't know much about this), or a dirty sensor as I've noticed a decrease in sharpness since I got my camera. I've also heard that shooting Jpeg actually comes out sharper than Raw, doesn't make sense to me so if someone can explain, I understand the difference in data stored, but wouldn't more data = higher sharpness.

I know that was long but thanks for the read, you can check out any of the links in my sig for examples.

Thanks,
Zack.

Sparknotes: Why aren't my photos coming out sharp: Workflow, dirty sensor, or lens calibration issues. I have a decent body and good glass.
