Canon 20D

  1. Hey guys i picked up a Canon 20D today, and i fired off some test shots along side my XTi and i have ot say i was NOT impressed. the 20D performed poorly compared to my XTi. the 20D was extremely soft and pixelated , even on the computer in light room, the LCD sceen isnt as good as the XTi so i went off the PC screen, i read a lot of reviews on the camera that spoke nothing but good things, unfortunately i was extremely let down. the end results from the 20D seem to be more along the lines of the 10D or lower megapixels
    Settings for both camera and each lens used
    75-300 USM IS 4-5.6
    18-55mm STM 3.5-5.6 (NEWEST RELEASE)
    F/8
    ISO 200
    500 Shutter Speed.
    For 20D, Parameter 1 (pre adjusted sharpness, contrast etc)(parameter 2 looked even worse)
    For XTi (Standard)
    My XTi preformed fine, my 20D preformed terrible. i really hope i didnt waste 200 on it. ive been a photographer for 4 years and do professional work, published in magazines etc.
     
  2. What does 'pixelated' mean? Seems like it means something different every time someone says it. I assume you are viewing at greater than 100% magnification so the images look the same size? Don't do that and it won't look 'pixelated' whatever that means
     
  3. There's nothing wrong with the 20D. Either you got one that isn't working right or you aren't using it right and comparing the images in a valid way.
    You really shouldn't expect to see a lot of difference in image quality. Noise should be about the same, dynamic range should be similar (maybe a touch higher for the 20D at higher ISO settings). You might see a touch higher resolution from the XTi.
    Sometimes Canon tweak the Rebel series default parameters towards consumer taste (higher saturation, more sharpening etc.).
     
  4. I agree with Bob.
    After going from a Bridge digicam to the 20D, I was initially disappointed, but when I started working with it, it soon became apparent that it was an excellent piece of kit that provided really good images.
    It may be worth posting some sample images to give us a better idea.

    Hi, Brandon.
    I have 20D and 450D (XSi - a little bit newer than XTi) and I can't see any important differences as image quality is concerned. In Tenerife and Rhodes folders im my portfolio I have exclusively photos taken with 20D, while in Thassos and Zakynthos - with 450D.
    My advice: shoot RAW's and process them to achive desired result.
     
  6. I use a 20D and 30D (same sensor) and they're excellent cameras. I just used them for a wedding shoot.

    Seems you have a problem with the camera or it's something you're doing in PP. Maybe post some examples for us?
     
  7. I bought a 20D originally, and after that was zapped by a focus confirmation chip, bought an XTi in case the repairs weren't done in time for a trip I was taking.
    I never saw any real, perceptible difference in results from the 8 and 10 MP cameras.
    I am still using that 20D, even though I've moved up to higher pixel count for other reasons. As Bob says, either you are comparing them incorrectly or something is wrong with the 20D you got.
     
  8. Pixelated as in viewing at 100% and it looks like im shooting with a maybe 1-4 megapixel camera, no where near as sharp as my XTi.
     
  9. ill show you guys one ive taken today, it seems to have some sort of a contrast problem as well. and yes the firmware is up to date. I was using my T2i religously until i started to notice these problems in it as well, so i sold it and bought a 20D, Maybe its the fact im using ISO 400 in the 20D and not something lower?

  10. That image looks absolutely fine to me. Not sure what you're seeing. If anything it looks maybe like a dirty sensor (if you mean the sorta mottling on the front of the train) or one cleaned and left with something smearing.
    Here's a 20D shot from many years ago, about the same size, doesn't show that pattern...

  11. You're going to have to post small, 100% crops from each camera, otherwise we won't see anything. Images should be of the same subject, with the same lens, shot at the same ISO and exposure, otherwise comparisons won't mean anything.
    The 20D is fine at ISO 400.
     
  12. I'd suggest shooting the tests in RAW on both cameras ans use the same software/settings for raw-conversion to eliminate differences from the in-camera processing.
    I'm another fan of the 20D. My 7 1/2 year-old body still gets use:

  13. My 20D has been the backup camera for my 5D2 for several years, It's still an excellent camera, and is now my wife's primary. For comparison, here's a shot from a few years back.

    At ISO400 a 20D is a fine piece of kit.
    It can be pushed to 1600 and 'H' also - representative outputs at those higher ISO's are shown in these samples. Some are JPEGS SOOC:

  15. Hi Brandon, The locomotive shot was taken without any filters on the lens? Curious about the glass windscreen of the engine, I have seen that effect with polaroid eyeglasses looking at windscreens of cars, has your 20d been adjusted in any way ? I have the 20d and not seen those effects at the settings you have provided , interesting .... regards miken
     
  16. PS I guess you have done a complete reset of camera and custom functions? Or reset with removal of all batteries and then use another set ( include the slim battery for date/time)? miken
     
  17. PPS Is your digital darkroom, photoshop etal in neutral processing? I guess so? Miken
     
  18. Brandon, you said the T2I began having the same problem ,and you then got the 20d, and the problem continues? that is really unusual, are we looking for a solution outside of the cameras actual performance? regards miken
     
  19. And you were comparing the 20d to a xti at the beginning of your post, or are these two cameras the same? miken
     
  20. The camera isn't set to something silly like JPG/Small/Basic is it? I tried that on my 30D years ago and at 100% it had tons of compression artifacts
