Hi Everyone,


Alexniedra - The purpose of the 100% crops is to show you exactly what you get from the camera. I can add the XSi results scaled up to the T1i's pixel dimensions if that is wanted. They will be a little softer than the T1i results, but not dramatically different. Scaled down T1i results would be sharper.


Benjamin - Right - What will the 60D bring us? Likely full frame rate 1080p HD video at least.


Jon - Thanks! I'll change that word.


I'm looking to remove ALL confusion over DLA. I first included it to help people understand why their images were soft - to answer the question "Why is my f/22 photo soft even when I used a $2,000 L lens?" (to take the extreme example). I fear I might have still caused misunderstanding for some.


Jesse - That is a great lens - good choice in my opinion.


I'm not seeing any T1i image attributes that noticeably stray from the previous Canon bodies. Canon's auto white balance under tungsten has never been good, but it is easy to change the selected white balance in-camera or in-post. Though I didn't take a scientific measurement, I didn't notice any significant change in dynamic range. You can look for differences in the color block example.


The lens used for the testing can make a huge difference in the results. I have both the 50D and the T1i results loaded for the Canon EF 200mm f/2 L IS USM Lens (link to comparison) in the ISO 12233 Chart tool, but I discovered that one of the 4 flashes was not firing for the T1i test. I'm going to be replacing these results soon.


There are a lot of other factors that can make big difference in image quality. Shooting RAW can be one of them. Noise reduction is another. Sharpening is another (the ISO 12233 chart results have very little sharpening applied). Comparing one brand to other further complicates the process.


STL - While your plan is not a bad one, DLA will probably only be an issue for you if you are reviewing your narrow aperture results at 100% on screen or printing to a huge size. And even so, the T1i will give you more detail to work with. I think a low-cost full frame body would be a big seller. A refreshed 5D (add sensor cleaning, Live View ...) would be very popular.


Regards,


Bryan
