I've been trying catch this woodpecker for quite some time. I found a little patch of woods the other day that was very active. Stalking has not worked for me so I planned on sitting. Sure enough after a couple hours he went to work on a tree about 15 yards away. I was pretty fired up about what I got until I did a search and looked at the examples previously posted. Below is the shot straight(converted raw to jpg) out of the camera and the best I could do with Elements 9. What did I do wrong?

Is this lens a sigma 120-400?

Yes, Sorry, 120-400.
It was pretty cloudy that day and I was in the woods. I thought an ISO of 640 should have been acceptable. My widest Ap at 400 is 5.6 so I wanted a bit smaller than that. I was thinking F8 would be crisper and give me more DOF to insure focus. Birds can be twitchy so I didn't want to go below 1/500. If I could have gotten 1/2000 at ISO 200 and F8 you can bet I would have been there. My meter showed I was exposed properly and the histogram looked correct. I have found that those are great tools for exposure but have nothing much to do with sharpness.
I had assumed you probably already knew everything i was saying, when i was saying it. I just thought i'd share anyway... in case you didn't.

IMO there is nothing wrong with the pics ,
considering the distance .
try to get closer ,
at 400mm there is not mutch room for cropping .

How many photographers does it take to change a light bulb? 50. One to change the bulb, and forty-nine to say, "I could have done that better!"

Nope, no tripod. Wondered about that. I was hoping the shutter speed would cover the hand held. The next day when I went out I took my monopod but didn't get any shots. I was going to take the tripod out today with me but did not make it into the woods.
Do most of you birders use a tripod?

I think a Canon 7D with a Sigma 120-400 can provide very sharp images. I'm trying to figure out why it didn't in this case. Maybe it was just a combination of no tripod, no flash, heavy crop.
Here's some probable evidence that the lens and lighting are the critical mistakes (if you can call them mistakes) in your shots here. I'm shooting an inferior camera the GH1 with a crop factor of 2.01, and below is what I get with a good position to the light, with a nice lens attached, and always on a tripod - always. I hope you don't mind if I flood the post with images but for me personally it makes a tremendous difference if I can see 5 or 10 instead of 1 or 2 when I'm trying to evaluate these kinds of things for myself. First I'll show some FD 300/2.8L samples and then some FD 300/4.0L ones. 300mm on my camera is about 601mm and the 400mm on yours is about 640mm - so petty close to the same. My sensor sucks compared to yours tho - which just means I can't really go above about ISO400 (for birding) and I get less Dynamic Range (DR) than you - err, it also mean I get a little lees detail (resolution) as your cam is 18mp and mine is only 12.
All of these are 100% crops, all manually focused, all have EXIF embedded, and all are wide open (f/2.8 or f/4.0 respectively), here goes:
Even tho there's some motion blur, notice that the direct light on my side of the bird really brings out the detail.
You can see some noise added because I bumped the exposure in PS. This is also using the 2X-A Canon FD Extender. So this is 1,200mm equiv actually.
This exposure is also bumped way up.
Exposure bumped considerably.
Exposure Bumped considerably.
Exposure Bumped somewhat. Slightly OOF too. With these last three I wanted faster shutter without changing the ISO so
I underexposed with the intent to push it in PS. Here's another one of him slightly better focused but his pose sucks.
OK, so that was the nFD 300/2.8L. I dig this lens! They go for between $600 and $1,200 depending on how beat up they are. Of equal IQ is the nFD 300/4.0L - the only difference being that it's not as bright. The 2.8 has fluorite elements to maintain the same IQ while also allowing the wider f/2.8. Here then is the 4.0L - typically $400 ~ $600. Some of these are BIFs so there is some motion blur too.
And you can see more of the nFD 300/4L here: http://tesselator.gpmod.com/Images/_Image_By_Lens/Canon_FD_300mm_F4L/ or navigate around to see other lenses I've sampled for on-line. Almost all of my bird shots are 100% crops or very near that. So if you come across a bird shot it's probably 80% ~ 100% somewhere abouts.
Anyway that's my input. I have a lot of images that look like yours (not on-line tho) and most of the reason is less than excellent glass mixed with poor lighting. BTW, if it's an easier fit there are some Nikkor ED lenses that are on par with the 300 and 400mm Canon L lenses too!
Have fun!
