Originally posted by FHPhotographer newarts, sorry about that, I had forgotten using USM so I stand corrected.
Also, you have answered the question I originally asked. If I follow you (and correct me if I'm wrong), this is a fair representation of what the equipment can deliver, so what I got is as good as the equipment can give (under these conditions). Now I have to decide if that's good enough, or if I should invest in equipment that will give me more. Thank you,

I think even perfect equipment would not record the scene much different from what you got. The picture looks flat because the detail in it was all clustered around the same average brightness.
I checked the distribution of brightnesses on the photo posted. The brightest brights were not overexposed but were about twice as bright as the photo's average brightness. Similarly, there were a small number of really black blacks, and they too were faithfully captured by the camera.
The camera did a good job of capturing the entire range of brightnesses from maximum to minimum, but that resulted in not much range for the remaining 99% of the image brightness clustered in the middle to be recorded, hence the image looked flat as your brain ignores the small fraction that's too white or too dark.
However, the camera did not do what your brain does, it did not ignore the whitest spot nor the darkest spot and expand the detail around the average. In the following, I did that for you. I added no sharpening and did nothing to artifically enhance anything.
Here's the photo and a histogram graph of the brightness distribution; notice that almost all the data is clustered around the middle with almost nothing at the high & low ends. The broad hump is the gray wall and the sharper peak is mostly the twigs and leaves.
A perfect camera set up to capture the brightest and dimmest parts of the scene would give about the same result.
I subtracted about 10% of the brightness to get rid of the useless "too black" blacks then increased the contrast to expand the detail of the remainder (this also made a few of the whites "too white" - the spike at the very right hand side of the graph.) I think you'll agree this is a much better looking photo.
But it is not much different from what the camera recorded.
Your camera might be set up to get as broad a range of brightnesses (Dynamic Range) as possible - while this sounds cool, it can have the effect of decreasing contrast. Perhaps that contributed to your result?
In summary, I'd want to see more examples and know how your camera is adjusted before I'd tell you you'd do better with new equipment (by "better" I mean recording more perfectly what's actually there.)
Lord knows there are many cameras out there that seriously distort reality with too much contrast, sharpening to "punch up" edges, and saturating colors to make clown-like images.
You are best off to start with grabbing what's actually in the scene THEN adding enhancements. I think your camera got close to what was actually there.
