New T5i vs old 400D , pics no better on T5i ?

Hello all , I just bought a T5i as my third DSLR . I had a 300D and sold it for a 400D which I still have , and now a new T5i. I have been taking pics and zooming in on them both from each camera . After seeing no real noticeable improvement in the new T5i , I took pics in manual with each camera . I took the pics within 1 minute of each other . After numerous pics , I wound up trying to be as precise as possible . On each camera I used the same lens , (canon 70-300 IS zoomed to 300mm ) in the M or manual setting .

The shutter speed was 1/100 sec. , ISO of 400 , and f8.0 on both cameras . I used the center single point focus option , on the same spot about 150 ft from the camera . White balance was auto and AF mode was AI focus AF on both cameras and both were at evaluative metering mode .

Personally, I use One Shot AF when testing my cameras. Assuming you have the non-L 70-300 zoom you will see much sharper images at the wider end (70mm).

No mention of a tripod, 1/100 second at 300mm is not where I'd want to be when testing a camera and/or lens. For me a tripod is de rigueur when testing my gear.

After a pic of each like that, I took one on each at 1/1000 sec shutter speed .

I viewed all pics using the software that came with the T5i , Digital photo Professional . I viewed all pics at the maximum setting of 200 % expecting to see about a 2x clearer pic from the T5i. when zoomed to 200 %.

DPP isn't good at 200% zoom, jaggies will ruin just about any image from any camera. Stay at 100% when trying to assess image quality or use a program that does a better job of scaling.

400D is a 10 mp camera and T5i is 18mp.

I think the newer cameras are using stronger AA filters although I'm unclear on why. My 40D (also a 10mp sensor) appears much sharper than my 7D under the same conditions. But my EOS M with the same 18mp sensor seems to have a weaker AA filter which results in sharper images OOC with no PP. Go figure. Of all of the cameras I own my G10 produces the sharpest JPEG images, the EOS M would be second, the 40D would be third, and the 7D would come in last. You can get much sharper images using DLO and shooting RAW of course.

I have gotton the same results no matter what I have tried as I see NO difference between the two cameras pics. Is the normal ? Tom

You're looking at images from both cameras at 200%, try looking at the images at a more normal size. As already mentioned, use a program that scales better than DPP. For quick checks of images I find Faststone to be excellent. Even ZoomBrowser does a better job of scaling. Version 4.0 of DPP seems to have this corrected but only supports 4 bodies.

Spend less time worrying about the camera and more time shooting!
