I'm having a bit of an issue with image quality and not really sure if i'm just expecting to much
equipment
60D
18-200 canon ef-s lens
50mm 2.5 macro lens
Now about 4 weeks ago I bought
60D
tamron 18-270 lens
canon 50mm 2.5
very unhappy with the quality
so went back to the shop and they tried out the lens and decided it had a focus issue
so replaced for a canon 18-200 as the replacement tamron still looked bad
I had my laptop in the shop
next day still unhappy went back
and we tried a 50mm 1.4 and a 100mm canon lenses and also a 17-40L on the new 60D body they decided the body was at fault
so replaced the 60d - about 10 days ago
but i'm still not convinced , and tried on a different quality screen - but i only have a
sony laptop with dedicated graphics - 1600x900 resolution
and a new i5 Fujitsu which does not have a great display - 1366 x 768
so not sure its the screen, eyesight or what
I have taken some pictures at a different shop using their 60d and 18-200 canon lens and they look the same
so i think it must be me
now i was playing with some iso settings ready for taken some marine fish tomorrow and I have taken some shots of a vase , clock and an apple with both lenses on a tripod with remote control release
manual focus, used live view and x10 focus and also auto focus single shot
I have some images on here taken with both lenses as wella flower and a brick wall
images from canon 50mm & 18-200 zoom

I have looked through POTN and seen pictures taken with the same lens and they still look off
I can load the images here - but whats the best way to show a 20MB file here
do i crop and then reduce the pixels and compress with jpg
or ?
i also took some images onn my old pro1 - but not happy with those
any one got a high quality image from a 60D - 18-200 I could be emailed
EDIT
I just realised looking at various forums, that on the 18-200 IS ,I left the IS on while on a tripod and the article mentioned it would degrade the quality of the image
it also talked about setting up the camera so it was 50x the focal length and largest aperture - so on the 50mm - that would be 2500mm 250cm 2.5m i was only about a foot 2/3 or less of a m
edit
i have also put the full RAW in DNG format on this share - 4 files of the bricks and flowers approx 20Mb eaxch
