5D MkIII Eye Sharpness Capability
First off I know sharpness of images is a function of many elements. The lens in particular plays a huge role in how sharp an image can be resolved. Also the AA filters, Noise reduction, and post processing all play a role. I do not want to try to explain or learn the science behind what makes an images, specific eye tack sharp.
I do however wish to hear from other 5D MkIII owners. I want to hear from them on how their 5D MKIII renders eyes specifically. Also is you were to do a portrait sitting and did a 10 shot sequence of images, how many of the files would have the tack sharp eyes that render the Iris and it's fibrous texture nice and clear.
I would love to see some images that show how, "Tack Sharp" their eye examples are as well as the lens used to make the image.
I have been pulling my hair out to make portraits that render the Iris portion of the eye that shows all of the wonderful fibers and textures that are actually present.
Here is an untouched 5D MkIII file (cropped only) of my eye 70-200 f4L at F11 Iso 800. I made more than several attampts to capture this image. Self portrait is a pita
And a Nikon Cool Pix Image of EYE made in 2002 with a Nikon Cool Pix
Now here are some typical looking eyes that I have captured. 85 f1.2LII at F2
Below is an example of what the eyes from above would look like in a finished print (the eyes look great until you get to 100% crop)
The finished portraits are nice, but when I look at a 100% crop of eyes, they do not look like I would expect them to look. Again I am sure it's a combination of reasons. I am more interested in the images other MkIII owners create. As well as the lenses used to make the shots and any examples you choose to share.
This non tack sharp eyes thing has been a frustration for me for quite some time. I have a friend with a Nikon D4 who said he sold his MK III because it renders eyes more sharply. Can this be true? A camera sensor render an eye more sharply. Or is that some fan boi stuff? I mean I know a sensor has a lot to do with resolution, but can it make a world of difference? In closing I love my MkIII it is a fine camera that has made very very happy. I am just trying to see the results from other MkIII Shooters.
Thanks for your time, AKf
