Default Re: new camera body or an L lens

I went back and looked at the Exif
1st two images (from the 10-22mm)
- ISO : 100
- focal length : 22mm
- 1/50 at f16
2nd two images (from the 28-135mm)
- ISO : 100
- focal length : 135mm
- 1/40 at f16

I'll try with the 100mm macro lens too, to compare

Key thing on those pics - what was the shutter speed and how windy was it? If you had a shutter speed of say less then 1/60 and it was breezy enough to move the plant, then that would explain some of the lack of detail.

Other than that, did you shoot RAW or JPEG? If RAW how much sharpening (USM etc) did you apply??

1/50s, 1/40s is too slow. Put your ISO up to 200.

In any case, I don't think that alone is your problem. Read my previous post and try that.

Maybe there is a slight improvement, but it still looks soft to me.

Going back to your original post where you say 90% of your photography is landscapes, it is important to note that images taken from say 10:00 AM to 4:00PM will appear less sharp than those taken earlier or later due the angle of the sun, diffused reflections and UV. The earlier and later shots will have more contrast due to more shadow and the angle of the shadow and therfore appear sharper, though optically they won't be. Bright sunlight, snow, etc. will cause large and tiny highlight blowouts that make an image appear less sharp too. You need to determine the state of your equipment alone and then look at other factors that might contribute to apparent lack of sharpness as opposed to actual optical/sensor lack of sharpness. Make sense?

Well John, in color and sharpness they look all about the same to me, but viewing in a browser, though my monitor is very good and calibrated, isn't something decisive. I say it is the camera. By contrast here is an image from a 20D and a 35L. I would say that 80% of the differences between your shots and this one is camera.

Default Re: new camera body or an L lens

thanks for the input John_T, since the softness is occuring in all three lens, I'd have to agree.... but it occurs to me that I wonder if the UV filter is effecting this too...

Did you do any post processing on your image?

with some post process, I can get it close (I think)....

Default Re: new camera body or an L lens

I vote for the "L"

I helped my wife to shoot a wedding last weekend, my job was to get the "other" shots...candids. So to keep me out of the way and the camera out of peoples faces so I could actually catch their faces she put me shooting the
70-200L. f2.8

I also had used the our Tamron 2.8...WOW what a difference the "L" made in the clarity of photo's...2.8 vs 2.8...the "L" was VISIBLY better!

Yes I know that weddings are different than landscapes, but my wifes' landscapes WOW folks just fine and she uses her 70-200L for those too.

Agreed, hardly a qualitative difference between your shots. There is a muddiness in the colors and contrast too which is likely the camera.

The sharpening you did doesn't appear to have done much more that give you artifacts and the illusion that it is sharper, typical of when there isn't much there to sharpen in the original.

Depending on the quality of your UV filter, it will affect your images in two ways, one, reflections on and in the filter, and two, altering your colors. I don't use a UV filter at all, except maybe on hazy days. The lens shade and reasonable handling is more than adequate protection for a lens, so I find no merit for a UV filter on that score. Try the same shots without the filter.

The dragonfly shot is just any old shot I grabbed with no processing other than crop and jpeg cut down for the 100k limit. It is a 100% crop.

What bothers me the most on your images is the general lack-lustre colors and contrast, and other than the camera itself, the only other thing that occurs to me is that perhaps your sensor has accumulated a haze from air polution and condensation from going in and out of the cold.

On a few hiking trips I tried without the UV and didn't notice any difference in clarity.... think the 350 would get me the next jump up? I'd hate to take a $3000 camera (the 5D) snow shoeing ... and I'm not seeing good comments about the 30D ....

Your 10-22 is pretty much an L in EF-S clothing. Hack your rebel to get MLU and use f/8 to f/11. Avoid stopping down more than f/11 and wider than one or two stops from wide open. I shoot landscapes at f/11 to get the DOF anyway.

It might be an issue with your camera body. You can send it to Canon to calibrate.

If you can't get nice sharp shots from your 10-22, I don't think moving to 30D/5D or getting an L would help.
