p.1 #1 · p.1 #1 · 7D Mark ii and 100-400 mark ii review Day 3: sharpness and ISO results


I am an IT professional with a photographic hobby. I wrote a javascript application to compare two photos with a slider. I can't get it to work on FM, so sorry this time you have to hit my website to see results. The script does not work on a mobile device. So please view on full browser.

ISO test results

Sharpness and Telephoto Test Results

This weekend will be the last of my field testing before I post the final overall review.

First three days reviews are on FM.

This has taken way more time than I expected.

Thanks for stopping by! Life is good and I am blessed,
Kent

The images from the first three days review on FM are remarkably sharp in my opinion and I would certainly be happy with results like that. The high ISO and sharpness Telephoto between the 7DII and I DX using the 100-400II really seems to show the detail and sharpness advantage of the 1DX (at least to my eye) Thank you for taking the time and effort to set up this comparison.

For the price difference, and FF versus crop, I would hope so.

The two tests are difficult to compare at lower resolutions, they all look good to my eyes. I would also question shooting the 7D2 at f/11 since it has a higher pixel density than the 1Dx it might soften the image some. Again at the displayed resolution it's hard to tell.

The JavaScript slider is cool. It definitely works well to show the crop factor effect of the 7D2.

Thanx for posting this Kent. Your tests do show the benefits of "A Few Dollars More". (If you don't get the reference, google it.) A neat way to compare for sure. If you decide to repeat this kind of test, I would suggest an image or two at 100% for the pixel peepers ~ Ron

Thanks Ron, glad people are enjoying the slider. I walked away from it a couple times! Came close to giving up, but I am just to dang stubborn!
