Never fails to amaze me the same stories you hear about this lens- never use it at 400mm, never use it at 400mm wide open (f5.6), too soft at 400mm f5.6. Enough already.

This lens is sharp at 400mm and f5.6. If you choose to shoot it at 400mm and f5.6 at the closest focus distance (less than 10 feet), depth of field is non-existant- it's not a lens performance issue, it a basic law of optics issue. If you're someone like the guy at Luminous Landscape and you can afford a 1Ds Mark II (maybe 3 or 4 of them), a 500mm f4, 300mm f2.8, etc., the 100-400 will be a pedestrian lens with pedestrian performance compared to that type equipment. If you are the average type person where the 100-400 is a major investment and shoot it at 400mm on subjects the where it makes sense to shoot at 400mm this lens is plenty sharp wide open at 400mm.

I've attached an image I shot the day the lens arrived at my office. I'm on the 19th floor at my building. I shot a very boring scene at ISO 1600 on my 10D to test the resolution, zoomed to 400mm at f5.6. This image is darn sharp. I'll also post a 100% blowup the small area in front of the bus where the plates are clear and sharp.

Thanks Greg, that's what I want to see out of the 100-400. Now if I can just find the time to work with mine.

One great example of how to use this lens. Last week I was at my daughter's region band concert. I knew I'd want to stand up a little and take pictures during the concert so I moved myself to the very back row to stay out of everyones way, around 30-35 yards from the stage. This was shot at 400mm, f5.6 at 1/50 sec at ISO 1600 with my 10D, and filtered in Neat Image. The slower shutter speed alone should have made this almost impossible at 400mm- Image Stabilization is an eye-opener with this lens. I really don't think I could have asked for much more.

Of course, sports outdoors during the day where you can stop down a little it gets super sharp. Here's my daughter, the catcher. 400mm at ISO 400, 1/640 sec at f11. I was standing down the rightfield line well beyond the dugout when I took this.

Greg, thanks for sharing with us. You are right, this lense "is" my 600mm DO lense. I hope I will someday get out of dog house for spendng this much money on camera stuff. I may some day have a really good fixed lense, but not in the forseeable future. I'll be I speak for Trout Man too.
Trout Man, don't be afraid to hand hod that lense- the shot I posted was about 45 yards out hand held.
This lense is day and night better than the cld Pentax I had. Wow. It does appear that it is going to be sharp enugh to test me.
Greg, your shooting examples are very helpful also. I tried only F8 and it was a good place to begin. I believe Eric suggested that.
Thanks to all of you for your help.
Trout Man, lets see some shots LOL, enjoy your new lense.

OK Guys, it's a crappy day out so let me see what it will do under those circumstances. Maybe I can find something out in the yard to shoot from the rear deck...stay tuned.

EDIT ADD: Here's a shot of the gas meter out back. It's shot at 400mm ISO 100, F5.6 @ 1/80th on Av. Not too scenic but all I had time for today.

Image has not been touched other than to re-size for this post. Distance to subject is 75'; not as colorful as the wood duck or the 19th floor bus shot but
